Thank you for using Embarcadero DB Change Manager! Its compare, synchronization, data masking, and auditing capabilities let you track and report on changes, roll out new releases, and pinpoint performance problems resulting from changes to the data, schema, and database configurations. By comparing a live database to a schema or configuration “snapshot” administrators can quickly identify changes and correct problems. By monitoring configuration settings, DBAs can ensure compliance with regulatory policies and performance standards, and maintain overall database performance and availability.

Upgrade Notes

DB Change Manager 2016 should be installed in a different directory than 4.x or 5.x versions. If DB Change Manager is installed in the same directory, the following error will result at application start up: "Unable to read workbench state. Workbench UI layout will be reset."

If DB Change Manager is already running, you can also modify the Workspace directory by choosing File > Switch Workspace > Other from the Main menu.

DB Change Manager 2016 provides an upgrade process for moving jobs and other information from an existing Change Manager 4.0, 5.0, 5.1.x, 5.5.x or 5.6 installations. No upgrade process is required to move from 6.x installations to Change Manager 2016 (6.3).

NOTE: You do not have to upgrade to 5.6 and then to Change Manager 2016 (6.3). The import procedure is the same.

Upgrading from Version 5.0, 5.1.x, 5.5.x or 5.6 to Change Manager 2016 (6.3)

All objects can be imported from version 5.0, 5.1.x, 5.5.x or 5.6 to Change Manager 2016 (6.3).

To upgrade from 5.0, 5.1.x, 5.5.x or 5.6:

1. Make sure that the earlier product is not running and that no command line jobs are being processed.
2. Install and run DB Change Manager 2016 in a different directory than the previous installation.
3. The Welcome to DB Change Manager dialog opens with the Setup and Import data sources, jobs, and settings from a previous version import options selected.
4. Click Get Started to launch the Import Wizard. Alternatively, you can launch the Import Wizard from the main menu:
   • Select File > Import.
   • Select Change Manager Workspace from the Embarcadero group and click Next.
5. Select the version of Change Manager from which to import.
6. Select the location of your DB Change Manager workspace. The default value is the default workspace, so you need only change this value if you configured DB Change Manager to store the workspace in a custom location.
7. The wizard imports the items from the previous Change Manager version. Click Next to continue through each step of the wizard.
8. Click Finish. The jobs are imported to Change Manager 2016.

Upgrading from Version CMSchema 4.0 or CMData/Config 4.0 to Change Manager 2016

The following objects can be imported from version 4.0:

• data sources
• all comparison jobs (data, configuration, and schema)
• configuration archives
• configuration standards

The following objects cannot be imported from version 4.0:

• schema archive versions
• synchronization scripts
• reports
• command line automation (scheduled jobs, batch files, etc.)

Note: 4.0 should remain installed to access any archives and reports.

To upgrade from CM Schema 4.0:

1. To import schema comparison jobs from 4.0, obtain and install cmschema_40_932_upgrade.exe from your Embarcadero Technologies Support representative.
2. Run cmschema_40_932_upgrade.exe to convert the schema component jobs from version 4.0 to 5.0, which uses an XML-based format.
3. Follow the steps as described in the previous section, "Upgrading from Version 5.0, 5.1.x, 5.5.x or 5.6".

Known Issues

General

• Saving jobs is not recommended if they trigger errors on runtime. Problems may occur and some functionality may fail to execute.
• System Tables, Indexes, and Primary keys created using Oracle Text indexing (CTX_DDL package) are not filtered by the Ignore System Objects filter. The solution for this issue is creating custom SQL Filters to exclude any objects the user does not want to include in schema jobs.
• Large DDL files generated through schema archive cannot be opened due to an eclipse memory limitation (~ 100.000 objects). The solution is generating the DDL in chunks that the user can easily inspect and modify.
• All procedures on a source schema will be picked up in comparison when checking Include dependencies on DB2.
• Job import doesn’t work if you change the default path for 5.x workspace.
• SQL Filter's conditions changed. In 5.0.3, the conditions within a SQL Filter are applied in an AND manner (an intersection of the conditions specified), but in 5.1, the conditions are applied in an OR manner (a reunion of conditions).
• Type filter text from Data Source Explorer does not apply correctly for imported data sources.
• The SQL Editor doesn't have an option to Set ON/OFF ARITHABORT for SQL Server. The DML generated by data comparison will fail on tables with indexes on computed columns or indexed views if the default Server setting is OFF.
• Running jobs from the command line is not yet supported for the All Access InstantOn version of Change Manager.
• The CM Schema 4.0 943 patch needs to be run twice in order to successfully update an older CM Schema installation.
• Code complete is available only after you enable indexing of the specific data source.
• While licensing, if the error "Cannot find base license" appears, try removing the line: "[email protected]/change_manager_5/configuration" from the change.ini file and changec.ini file in the installation folder of Change Manager 5.1.
• Users of InterBase may experience difficulties using the SQL Editor in some isolated cases. You can disable parsing for the SQL Editor script-by-script by right-clicking on the file in the Navigator view and changing the Parser Settings. Contact support for more information.
• The Open Scheduled Tasks button from the toolbar is not available for use with the InstantOn version for Windows 2008 OS. As a workaround you could start the scheduled tasks window manually from the operating system functionality or install the application.
• Quick Launch icon is not available for Windows 2008 and Windows 7.
• SQL Editor doesn't display big ntext fields for MS SQL Server caused by Eclipse limitations for simple text files. The characters are there, but can't be seen. If you copy the content of the SQL Editor and paste it in a document you can see that the characters are displayed correctly.
• Installing the application in the root partition C:\ is not recommended because serious problems may occur and some functionality may fail to execute correctly.
• Sync Scripts Import functionality is not available from CM Data and Config 4.0 to Change Manager 5.1 and newer versions.

Schema Comparison

• The Ignore Object Permissions option for schema comparison jobs does not work if the Enable Dependency Linking option is not selected in the Preferences page. By default, Enable Dependency Linking is unchecked for Oracle, so all Grant statements for Oracle objects are not extracted and compared.
• Identical views with different Header comments cannot be synchronized on SQL Server.
• Comparison fail views on SQL Server if the "Compatibility level" server property is set to 70=SQL Server 7.0.
• Comparison fails for Tables and Indexes on DB2 if the system temporary tablespace is a page size smaller than 8k. We recommend using a 16k page size so that Change Manger queries run seamlessly.
• When using DB2 version 8.1 with different collation between the source and target, the object matching will not be correct due to an IBM server known limitation.
• Identical views are seen as different when comparing cross platform objects SQL Server vs. Oracle due to text property which specifies the view columns on Oracle. The same problem occurs for SQL Server vs. Sybase, due to the way that Sybase returns the select statement.
• Identical Check constraints are seen as different when comparing objects on Oracle, Sybase towards SQL Server, due to the way SQL Server returns check conditions.
• When comparing tables among different versions of Oracle, the default values for Storage parameters will be removed from synchronization.
• The options "Ignore Constraint Names", "Exists in Target Only (Drop)", and "Ignore Specific Name" work only for object types for which all items are included on the refinements tab. Specific object selection will invalidate these option selections.

Data Comparison

• For MS SQL, you should manually exclude System Databases from any Data Movement and Data comparison (e.g. master, msdb, model, etc.) in order to avoid any alteration on data dictionary. See http://msdn.microsoft.com/en-us/library/aa260604.aspx and http://msdn.microsoft.com/en-us/library/ms179932.aspx.
• Data Auto-synchronization Limitations:
  • When updating the IBM DB2 client with new patches, or upgrading from the installed version, the client needs to be rebound to the IBM DB2 server. If rebinding is not performed, there will be problems in getting metadata using the DB2 driver. One solution is to drop and recreate the database if you are unconcerned about the data in that database. This will automatically perform the required bindings.
  • For tables having columns with data type DECFLOAT, data migration gives null pointer exception and the data does not get moved properly.
  • For tables having columns with data type MLSLabel Oracle driver gives a null pointer exception.
  • Data Auto-synchronization is not supported for versions of InterBase 2007 below Service Pack 3 (v8.1.1.333)
• Use the trim trailing spaces option when doing a cross-platform comparison for tables with binary, nchar, numeric or unichar data types towards SQL Server, because the server is appending trailing blanks and 0s when data is inserted in the tables.
• Random exceptions could be experienced when performing data movement jobs using MS SQL trusted connection caused by concurrency issues when Secur32, ntdll ( from Windows) and ntlmauth from dbconnection (DB Change Manager internal plugin) are accessed.
