Version	Date	Data Replicator/User Interface changes
6.2.0	04/29/08	Enterprise Manager: Fixed a problem in the Replication Wizard where it was not possible to schedule mirroring interruptions from the wizard because the ‘Add’ button was always disabled; Fixed an issue that occurred with Internet Protocol (IP) version 6 that occurred when resolving an IBM System i IP address from the System i library setup function; Fixed a problem that occurred when setting up a new connection. The checkbox to set up transactional replications was set to false by default; Added TransactionTS (transaction timestamp) to the log fields available from the Expression Editor; Fixed an exception in the Create Target Table wizard in the column definition step when the Next button was selected while a cell was being edited. Log Reader: Fixed a parsing issue when reading ntext columns in SQL Server transactional replications; Fixed a problem in trigger-based synchronization when both target and source connections had configured the same master table name. An error was reported in the log indicating that a record was missing in a log table; Fixed an issue in synchronizations involving a SQL Server connection when a shrink (or clean up) of the log was performed on the server. Transactions executed by DBMoto on SQL Server were reprocessed back to the original server creating errors of duplicate keys or missing records. Data Replicator: Fixed a problem with the SQLBulkCopy (insert bulk mode for SQL Server target) where the command timeout parameter was not set and the default (30 seconds) was used as a timeout.
6.1.1	03/14/08	Common: Introduced handling of a remote distributor for SQL Server connections; Introduced support for transactional replications using DB2 on i5/OS for server versions back to V3R1; Added support for trigger-based replication using SQL Server (including SQL Server Express Edition) as a source; Added trigger-based replication for Informix as a source database; Added trigger-based replication for Sybase SQL Anywhere as a source database; Added trigger-based replication for Sybase ASE as a source database; Introduced an "Initial Refresh" option for refresh mode replications (it was disabled by default); Introduced a control to handle an error that occurred when mapping to a LOB field and using bulk insert on replications that have DB2 for i5/OS as a target; Fixed a problem that occurred when running a bulk insert with SQL Server Native Client (OLE DB) as a target provider; Fixed a problem that occurred with the scheduled refresh where it would not run if the "Initial Refresh" option was not checked. API Library: Fixed a problem that occurred when calling the DisableReplication API. It would incorrectly check if the engine was running and generate an inappropriate error; Improved the API trace generation,so that it follows the Enterprise Manager trace settings, with the only difference that it creates its own trace file called DBMotoAPI.trc; Fixed some problems that occurred when communicating between the API client library and the Data Replicator with the TCP/IP connection. Enterprise Manager: Enhanced the Export Replication Wizard so that, when a replication is selected, the source and target connections of that replication are automatically selected in the wizard; Fixed a problem where the Export Replication Wizard, when creating the exported replication with a new target table, would use the list of fields from the original source table, instead of using the original target table; Fixed a problem in the Export Replication Wizard where the exported replication would inherit the Insert Mode from the origin replication even when that specific mode was not supported in the exported replication target database; Enhanced trigger-based replications so that, when a table is modified through the ALTER table command and the table is refreshed, DBMoto asks the user whether to regenerate the triggers defined on that table; Introduced repair functionality for transactional replications in cases where it is necessary to rerun a setup of transactional replication objects that have been removed or corrupted; Fixed transactional support in DBMoto connection objects upgraded from earlier versions where there was no transactional support for that database; Added a word wrap button in “Execute SQL Command” dialog; Fixed a problem in the Replication Properties dialog. When editing multiple replications, the Read Last ID function was only executed on the first replication in the list. Log Reader: Introduced the option to specify the path for creating the distributor database; Introduced the option to indicate an alias name for the server where the distributor is installed to support cases when the server network name is not valid to open a connection; In transactional replications involving DB2 on i5/OS, fixed a problem for TIME fields with *USA format and the value was 12:00 PM. Data Replicator: Extended the IRecord interface with the functions GetType, GetDBType, GetPrecision, GetScale and GetLength; Fixed a problem that occurred when aborting a transaction using the script function Record_onBeforeMapping or Record_onAfterMapping. If the transaction aborted was the last transaction in a mirroring interval and the Data Replicator was closed, the transaction ID would not be updated and the same transaction would be picked up once again when the Data Replicator was restarted; Fixed a problem where, in a refresh of a group, if the source table had no record, the target table was not truncated; Modified refresh behavior so that a refresh replication will only start according to the schedule. An initial refresh is no longer required.
6.1.0.25	12/05/07	Common: Modified the function that checks the existence of metadata tables when loading metadata. In some databases, the absence of a qualifier could generate an error during this operation. Enterprise Manager: Introduced the option to perform SQL Server mirroring and synchronization replications using triggers instead of the transaction log. This option provides a way to perform transactional replications with SQL Server 2005 Express, and with tables that do not have a primary key defined; Added the option to define a remote distributor for SQL Server transactional replications when setting up connections for mirroring or synchronization; Provided a way to refresh transactional replication objects in the metadata for SQL Server and trigger-based replications. This option is available in the Transaction Read Point dialog; Fixed a problem that occurred when opening the Expression Editor from the Replication Script dialog. All static functions defined in the global script were not loaded in the list; Fixed an error that occurred when changing a metadata qualifier. Clicking on Apply first, then OK did not refresh the metadata content with the new objects; Fixed a null reference exception that occurred when modifying a metadata connection for a database which does not support qualifiers; Fixed a problem that occurred when changing Distributor settings on a SQL Server connection. The password parameter would be saved incorrectly; Fixed a problem in the Metadata Restore Wizard. If a replication was scheduled with recurrences (refresh) or interruptions (mirroring and synchronization), the wizard imported the schedule settings but enabled the scheduler to Run One Time Only (for refresh replications) or Run Continuously (for mirroring and synchronization replications).
6.1.0.24	10/31/07	Common: Introduced a new feature to allow custom QCMDEXC stored procedure to be run on i5/iSeries/AS400 connections for remote commands execution. Enterprise Manager: Fixed a problem in System i connections where the properties ‘Temporary Library Name’, ‘Max Size Mirroring Block’ and ‘Journal Sequence Reset’ could not be modified and saved in the metadata.
6.1.0.23	10/24/07	Common: Added support for SQL Server timestamp column type; Added support for Informix .Net Provider; Improved the description of the message generated when loading the metadata in case of an error: the message would always state that metadata tables were not created even when the error was of a different nature; Fixed an issue when loading metadata upgraded from version 6.0. In some cases the metadata could contain schemas related to non-existing catalogs, preventing the metadata database from being opened; Fixed a problem that occurred when specifying a different metadata qualifier from the default database in the connection string. DBMoto would use the qualifier to verify the existence of metadata but then used the database of the connection string to create the metadata tables. Enterprise Manager: Introduced a new wizard that restores partial contents of metadata, allowing selection of single replications to be imported to an existing metadata database; Introduced a copy and paste feature for DBMoto connections. Now connection objects can be copied from source to target and vice versa and also among different metadata sets; Introduced a rename feature for the following components: metadata, source connections, target connections, replications, and groups; In the Replication and Multiple Replication wizards, introduced the option to use the source table name to name generated replications; Added a tool to the License Information dialog to visualize the number of replication pairs created on a metadata; Enhanced the license error message that can occur when loading a metadata to show the number of replication pairs defined in the metadata; Added a feature to change the login ID used in the Execute SQL Command dialog. This is useful for synchronization replications during the test phase when the dialog is used to execute commands and it has to be run with a different user so that the synchronization process does not skip the transaction; Table columns are now displayed using their ordinal value by default instead of using alphabetic order; Fixed a problem that occurred when mapping fields in synchronization mode through the Expression Generator dialog. Listing the Fields element in the treeview would only show the source table fields list, even in target to source direction; Fixed a problem where occasionally, after a general error, the Enterprise Manager would close but would still keep running in memory; Fixed a graphic issue, when using a Large Size DPI setting in the monitor configuration. The toolbar in the Enterprise Manager main dialog would expand vertically covering part of the controls below it; Fixed a graphic problem in the Field Mapping dialog with Unmapped fields in synchronization replications, when switching mapping back and forth, it would show the same fields as unmapped; Fixed a Null reference exception in the Replication Properties dialog when trying to open more than one replication by selecting multiple replications; Fixed a problem that occurs when dropping one or more columns (with an ALTER TABLE) on a table where a replication has been defined. After running a catalog refresh on the table, the metadata could no longer be loaded; Fixed a problem that occurred when dropping one or more columns (with an ALTER TABLE) on a table where a replication was defined with one or more Unmapped Fields. After running a catalog refresh on the table, the Unmapped Fields list was not refreshed; Fixed a problem that occurred when changing metadata connection properties using the Connection Properties dialog. The metadata would not reload using the new connection parameters; Fixed a graphic problem that occurred when the DPI setting was different from the standard (96). The form would grow in size every time it was opened. Log Reader: Fixed a problem that occurred when mirroring TIMESTAMP data type fields in Oracle; Fixed a problem where NULL values in UPDATE statements were not replicated when the source was a SQL Server; Fixed a problem with possible lost of transactions when the connection to the target database was lost; Fixed an IndexOutOfBoundException happening sometime in synchronization mode; Fixed a NullReferenceException when replicating from IBM System i (iSeries/AS400) using Arabic conversion classes. Data Replicator: Fixed a problem introduced in version 6.1.0.14. In some cases, replication script events defined inside a group were only called one time for the entire group, instead of once per replication; Fixed a problem with Unmapped fields. In synchronization replications, the unmapped fields were not retrieved correctly and they would generate an error if used inside a script function; Fixed a problem in synchronization when processing multiple transactions affecting the same record in the same replication interval.
6.1.0.16	07/30/07	Common: Passed Microsoft Windows Vista certification; Added support for enum data type in MySQL; Added access to the internal source and target connection from the replication script through the new properties InternalSourceConnection and InternalTargetConnection; Fixed a problem creating a Mirroring replication on a MySQL source connection when the master table and the source table belonged to different databases; Added support for System i/iSeries journals that reset the sequence number when the receiver changes. Log Reader: Fixed an exception in the initial refresh from an Oracle database when the last replication transaction ID was not available in the Oracle Log.
6.1.0.14	06/12/07	Common: Modified the application to be aware of activity relates to restart manager aware so that it responds correctly to requests from the system to close or shut down; Verified exception handling strategies to ensure that possible problems would not be hidden by a general catch block and therefore remain unresolved; Updated the metadata upgrade function to correct some upgrade problems and optimize the process. Enterprise Manager: Fixed a problem that sometimes occurred in the Multiple Replication Wizard where, in the Select Replications step, a non existing target table was selected and forced to be created before the processing step. Mapping information would not be visible and metadata would contain incorrect information. Data Replicator: Fixed an exception that occurred when reading the System i/iSeries/AS400 log after upgrading DBMoto to version 6.1.0.13.
6.1.0.13	05/23/07	Common: Added Windows Event Log messages in case of failure at startup of the DBMoto applications; Introduced a check when loading metadata to see if a table has no columns. This is in general indication of something that failed, but no longer generates an error; Fixed a problem in create table configuration in cases where there were alternative data type mappings depending on the database version: in some cases, the create table information would be erroneously set to null, generating syntax errors when creating tables; Added support for user defined data types in Sybase ASE; Fixed an issue in a function defined to parse (and modify) connection string values. It could cause problems with the LogReader when a connection with sysadmin privileges needed to be built in order to correctly set up a transactional replication; Fixed a problem that occurred when using SQL Server as source in transactional replications. If the connection used authenticated security, DBMoto could fail to determine whether the user was a sysadmin or not (and fail to show the warning when defining a transactional replication that a non-sysadmin user is needed for the connection); Fixed a problem that was introduced in the metadata update function. In a query during the metadata upgrade, DBMoto would erroneously prefix the column ‘ConnectionID’ with the qualifier defined for the metadata; Fixed an invalid cast exception happening while upgrading the metadata to version 6.1.0. Enterprise Manager: Fixed a null reference exception in the Connection Properties dialog when the connection settings were changed to use a different provider/database; Fixed an error that occurred when physically deleting a table that had been set up in DBMoto as the source or target of a replication. The ‘Refresh’ context menu on the table or catalog object would remove the table but not the replication from the metadata; Fixed an invalid cast exception when opening the Update License dialog and an invalid license was selected; Resolved an unhandled exception in the Replication Browser tab, when clicking on ‘Source Table, ‘Target Table’ or ‘Replication Mode’ column headers to sort the rows; Fixed a null reference exception in the Enterprise Manager window when clicking on ‘Refresh’ on a catalog or schema with no tables. Data Replicator: Fixed an issue with numeric fields having precision greater than 28 on systems configured to use ‘,’ (comma) as decimal separator character; Fixed a problem with the synchronization that could generate different errors during the execution. In some cases the data was replicated only in one direction, in other cases conversion errors were reported.
6.1.0.10	04/23/07	Common: Added the ability to set the order in which tables are refreshed in a group; Added support for numeric and decimal fields with precision greater than 28; Added the global events Replication_onError and Record_onExecuteError; Added a replication script event LogReader_onPrepareMirroring; Updated replication script events. LogReader_onBeforeTransactionsRead has changed name to LogReader_onBeforeMirroring, LogReader_onAfterTransactionsRead has changed name to LogReader_onAfterMirroring. DBMoto checks if these events are defined in a script on loading metadata and offers to convert metadata/scripts to the new names; Optimized code to load and save the metadata; Introduced the DB2 connection property CommitBlockSize to release database resources while refreshing and mirroring tables with LOB data; Added support for MySQL BINARY and VARBINARY datatypes (MySQL version 4.1.2 or above); Modified the Metadata wizard and introduced a metadata table qualifier property, used to indicate the specific catalog and schema where the metadata tables are created; Fixed a problem where Datetime formatting was not following a standard format; Fixed a problem in the LogViewer when opening log files with errors indented under other errors; Introduced an option to filter warning messages in the log that are displayed whenever an update or delete operation applies to more than one record at the target table; Improved log/trace readability on parameter values. When the value is NULL, it is logged as “<DBNull>”. When the value is not assigned, it is logged as “<null>”; Updated the configuration for MySQL. In version 5 and above, the maximum size of VARCHAR types has increased; Fixed a problem where SQLBase generated an error when loading tables; Fixed some issues with the TCP/IP communication between Enterprise Manager and Data Replicator. The metadata icon now shows an error whenever a problem in communication is found with the Data Replicator; Fixed a problem in configuring date fields, the InvariantCulture is now used to avoid conflicts in date formats depending on the regional settings; Fixed some inconsistencies in writing log messages on replications in synchronization mode. Sometimes the error message was not written to the DBMoto log but only in the trace; Fixed a problem in the communication between Enterprise Manager and Data Replicator on systems using IPv6; Fixed an error when compiling/saving changes to the global script while they where in use by the Data Replicator. A message has been introduced to warn the user that changes in the global script will be reflected in the Data Replicator only after restarting it; Fixed a problem with the obfuscation of the script method SendMail; Fixed a problem creating a mirroring replication using MySQL tables containing BLOB or text fields; Set a maximum limit for the size of the Default column in metadata fields table to avoid errors while loading tables with a default value that exceeds the maximum allowed; Fixed a problem where starting a replication group in mirroring mode could fail with an error indicating that a replication does not match the transaction ID used by other replications in the group; Fixed a problem where an unhandled exception could happen when starting and stopping the DBMoto service from the DBMoto service monitor; Fixed problems with Firebird when creating a target table. The syntax for the DEFAULT clause was incorrect. Also fixed some precision problems with the FLOAT data type; Fixed a problem when creating metadata on Sybase ASE. The QuotedIdentifier property needed to be set to 1. It is now it’s the default value in DBMoto; Changed functionality so that when a Ritmo/i5 Exception is thrown while reading the first entry in the journal, DBMoto retries the mirroring one more time at the next interval before reporting an exception in the log. Enterprise Manager: In the AS400 Library Setup dialog, introduced the option to indicate a different library from DBMOTOLIB for installation of DBMoto setup information; Optimized loading and sorting of graphical elements in the Enterprise Manager; Introduced a limitation on SQL Server connections. When the database has a transactional replication defined, the Distributor cannot be removed; Introduced a limitation on trigger-based log connections. When a database has a transactional replication defined, the master table cannot be uninstalled; Improved handling of LOB fields on DB2 mainframe platforms. When creating target tables with LOB fields, DBMOTO automatically adds the ROWID column when required; Added Oracle materialized views to the “Select Tables” dialog; Fixed a problem where, when removing metadata tables defined in Microsoft Access, the connection would remain open; Fixed a problem that occurred when changing CCSID values manually for DB2 (System i/iSeries/AS400) tables. The Object Browser did not refresh its information unless a different node was selected; Fixed a null reference exception in the Replication Properties dialog thato ccurred when editing the current transaction ID and the result was null; Added a feature to ask the user whether to remove the objects created in the database for transactional replications when switching to refresh mode; Fixed a problem where creating a table from MySQL to MySQL with a default value on a DateTime field would define the default clause without quotes; Fixed a sporadic multithreading error when closing DBMoto Enterprise Manager; Fixed a problem where, in the Create Table wizard, the datatypes in the Type column were not sorted alphabetically; Resolved a problem in selecting tables with descriptions longer than 50 characters, the maximum size in the metadata. The description is now truncated to 50 characters when loading the metadata; Fixed the “Define another replication group” flag in the Replication Group Wizard; Fixed a problem in wizard dialogs on table selection steps with the Schema combobox; In the Enterprise Manager, fixed a synchronization issue when closing the window; Fixed some SQL syntax issues creating tables on Sybase ASE; Fixed a problem where, in selecting tables on databases with a huge number of tables, the dialog would hang or throw an exception; Fixed a problem where, when removing an entire catalog from metadata, the schema was not deleted and caused a “catalog not found” error when reloading the metadata; Fixed a message box location. When an error happened during application startup, the message box would be displayed in the left top corner of the screen. Now it is displayed in the center of the screen. Fixed a problem in editing multiple replications with the Replication Properties dialog when the selected replication was modified; For System i/iSeries/As400 systems, a field’s Description column now shows the LABEL of the column; Fixed some issues in the Replication Properties dialog.

The Global Script column was not correctly loaded into the new metadata; Fixed a problem where the field mappings of the replication were not updated when opening a Replication Properties dialog and switching between different replication modes; Fixed a problem in the Options dialog Database Log settings where the number was not multiplied by 1000 as the label indicated; Fixed a problem in the Options dialog Database Log settings for the maximum number of messages. Once the checkbox was set to true, it couldn’t be reset to false; Disabled the option to modify or remove the metadata while running; Added a Refresh Recovery option in the Replication Properties dialog; Fixed an argument out of range exception while mapping a target column to an expression when user functions were defined in the global script. Log Reader: Managed an issue where System i/iSeries/AS400 log setup, when defining a new replication, changed the creation of temporary files from the DBMoto temp library to QTEM. Data Replicator: Fixed a Null Reference Exception during the refresh of a replication with a CCSID set on the source table or field; Fixed an Overflow Exception replicating to an Oracle table containing decimal fields with precision less than 3. The exception occurred when processing records with negative values for these fields; Fixed a problem that occurred when one replication in a group could not be run because no primary keys had been defined in the target table. The error message in the log indicated a generic error for the group and not for the specific target table; Fixed a problem where, if primary keys and other replication-related information was updated while the engine was running, once the replication was enabled, the engine did not refresh this information but kept using the former settings; Fixed a problem where Initial refresh was not executed when a recurrent refresh was set; Fixed an index out of range exception that occurred when recovering from an error on refresh for a group of replications. APIs: Fixed a problem where, due to a build issue, all exported methods were not accessible.
6.0.0.29	10/15/06	Common: Fixed a problem when a connection timeout was generated where the connection was closed and another connection opened. The problem was detected with a System i/iSeries/AS400 source connection, but it could also occur in other environments.

When clicking Next or Back repeatedly, without waiting for the step to complete, the handling function would throw an exception; Introduced new property in SQL Server connections to enable/disable the detection of the UserID and Transaction Timestamp during mirroring. If this information is not needed, performance during mirroring can be improved by skipping an additional step while opening the transaction log; Fixed a problem in the mapping dialog. The “Map to Expression…” menu item was enabled only in the popup menu but not in the toolbar menu; Fixed a problem in the mapping dialog. When reordering the fields columns (in both source and target fields lists) the arrows representing the column mappings were not refreshed; Introduced row and column line numbers in the script editor dialog; Fixed a problem setting the time intervals in the Replication Properties Scheduler tab: the fourth time setting was not saved (it was always 12:00).

The connection used was shared among replications causing errors when multiple readers were opened on the same connection; Introduced ‘Remove Trailing Blanks’ property in mirroring from iSeries/AS400 when using HiT OLEDB/400 or HiT Software Ritmo for iSeries: if this property is set to True in the connection configuration, DBMoto will accordingly remove blanks when replicating char/varchar/long varchar fields; Fixed a problem for groups containing more than 32 replications and mirroring from iSeries/AS400 tables belonging to different libraries where only the transactions of one library were replicated. Data Replicator: Fixed a problem with the insert mode BulkInsert. With Ritmo for iSeries, a single insert was executed instead; Fixed a problem where replicating to a Microsoft Access table containing Image or Text fields could generate an “Invalid precision value” exception if the data size was greater or equal than 512 bytes; Fixed a problem where SQL Server data types text, ntext and image were truncated to 16 bytes; Fixed a problem where a refresh filter was not applied if the source table did not have a key defined in DBMoto; Changed the Data Replicator service name to DBMotoSrv.

If a replication was created inside a group, it would not follow the replication mode of the group (specifically the initial refresh option); Fixed a problem sometimes encountered when closing the Enterprise Manager; Fixed a problem with the Enterprise Manager monitoring thread which generated an error with some providers (for instance, using Oracle metadata with the Oracle OLE DB provider); Fixed a problem with the replication status. When creating replications using the replication wizard or the multiple replication wizard, the replication status was always ‘0 – Idle’ no matter what was specified in the wizard; Fixed a problem which occurred when creating one or many replications using the wizards and a group was selected. The replication advanced properties were not saved with the values defined in the group. Log Reader: Fixed a problem when using iSeries/AS400 as a source and detecting the journal associated to a table (the table would not appear to be journaled even if it was); Fixed a problem mirroring a group with more than 30 replications connecting to an iSeries/AS400 source. In some situations, the log reading failed with the message “no entries converted or received from journal”; Fixed a problem mirroring from SQL Server when the database name contained special characters. Some “USE” statements in the log reader failed because of missing quotes on the database name. Data Replicator: Logged a message when a replication is suspended and resumed because of a scheduled interruption; Fixed a NullReferenceException when a date or time field was mapped to a constant value; Fixed an error when parsing Oracle REDO log strings containing TO_DATE clauses.

When reading the last ID, if the log file SEQUENCE# field is 0, the log file cannot be added to open the logminer; Fixed a problem creating a mirroring replication from SQL Server 7 where the message “Table ‘MSRepl_commands’ not found” was reported. Data Replicator: Fixed a problem with the maximum number of open cursors that occurred when using “Ritmo for iSeries”; Fixed a problem in “Ritmo for iSeries” with GRAPHIC and VARGRAPHIC data types; Fixed problem with FastLoad when target tables contain DECIMAL fields and the system regional setting has ‘,’ (comma) as decimal separator; Fixed a problem replicating TIME fields when the global option "Date/time Conversion Errors" is set to "Insert NULL values"; Fixed a problem that caused the following error message to occur when reading an iSeries journal: “FROM and TO values not valid. [SQLCODE: -443 SQLSTATE: 38501]”; Introduced a control to avoid loading replications belonging to a group when not all replications in the group have been enabled; Fixed a problem where, in some cases, the request to enable a replication was not considered by the engine.
5.0.0.18	01/16/05	Common: Introduced support for .NET framework 2.0; Introduced support for SQL Server 2005; Introduced two new versions of the SendMail function for use in scripts, to specify the SMTPServer and the target recipient; Fixed a problem where using the enmOperationType and enmLogFields data types in a script generated errors during compilation. Enterprise Manager: In Create Target Table, fixed an anomaly when prompting the datatype, size, precision and scale for the target table, calculated based on the source table; Fixed a problem where replications were not sorted alphabetically in the Replication Monitor; Fixed a problem where in the connection wizards, when setting up a connection and going back and forth with the wizard steps, the connection parameters would be cleaned up; Fixed a problem in the Fields Mapping dialog when maximizing the dialog due to the loading of the center area containing the arrows; Introduced new feature to allow custom automatic mapping. The user can define any number of script functions to use when creating a replication to automatically generate mapping between source and target fields; Fixed a problem when using manual CCSID settings in DB2/400 tables, when the CCSID was first changed and refreshed back from the database; Fixed a problem in the Multiple Replications wizard. When creating a replication in synchronization mode, the mapping dialog would show only the source to target mappings; Fixed a problem in the Replication Wizard when creating a replication with a DB2/400 table using a journal library name (or journal name) containing special characters (like ‘.’). Log Reader: For SQL Server, introduced an error message when the SQL Server edition installed does not support replication; Fixed a problem when installing the distributor on SQL Server 2005, the @encrypted_password parameter is not supported. Data Replicator: Fixed a problem using the RRN when the table name contained special characters; Fixed a problem with Date and Time conversions using DB2 for iSeries as a source database. Set Up: Introduced upgrades when DBMoto is already installed.

Enterprise Manager: Introduced more detailed information in the trace file when running the migration from a DBMoto 4.1 metadata; Fixed a problem when updating a disabled replication with the engine running. The status would not be refreshed and the ‘Enable Replication’ popup menu would stay disabled; Introduced a check for platforms where metadata is not supported (iSeries/AS400 and zOS/OS390); Fixed an error in the SQL Server distributor dialog. When exiting with Cancel the changes were saved in the connection. Log Reader: Fixed a problem where, creating the Distributor on SQLServer, DBMoto was always using the user sa instead of the user set in the distributor properties of the connection. Data Replicator: Fixed a problem where in some cases Time data were not replicated. Set Up: Fixed the Setup splash screen which reported “Beta 5 version”; Fixed a problem where there was an error starting the PC: “The service DBMotoDR is not installed”. The DBMoto setup configured the DBMServiceMonitor.exe application as a startup application even if DBMoto were not installed as a service.
