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.
What's New in Change Manager 6.0
See the DB Change Manager User Guide at http://docs.embarcadero.com/products/change_manager/
or the online help for details about the new features. Changes in this
in the 6.0 release include:
You can export and import jobs as zip files.
Schema archive job performance is optimized for improved usability and
scalability. The memory footprint was reduced and you can now
successfully run larger schema archive jobs. You can browse pages of
results, filter and select or deselect objects, and see a summary
report of the objects used by the DDL extraction script.
If multiple valid licenses are detected at startup, a dialog prompts
you to select the preferred license.
When comparing master catalogs or user mappings in a schema comparison
job, you can select multiple targets against a single source. The
mapping page has changed allowing the user to map one source
database/user to multiple database/users on the target datasource.
Data comparison job performance is optimized to support larger jobs.
For schema comarison and schema archive jobs, the Include
Table Dependencies option will extract all table
dependencies. By default it is not selected.
To improve performance for many cases, preferences for the SQL Editor have
changed. The Enable SQL Parser
option now includes a file size threshold. By default, SQL files
smaller than 700 KB enable the parser, and files larger than that
disable the parser. You can configure the file size. The Parsing Delay
option is no longer supported.
• SQL Editor Results Viewer
preferences include the option to save the output to a file.
Data sources have a Category
property so that you can sort them by Development, Test, QA, and
Production color-coded categories.
The data comparison job preference Drop and Recreate Foreign
Keys behavior is clarified. By default, this option is
selected. If you choose to deselect this option, a data comparison job
will generate ordered table insert and delete statements. If the
default comparison key is changed the DML generated by CM/Data may not
respect referential integrity. Also, in order to respect referential
integrity all dependent tables must be selected in the mapping

Important Advisory Notes
- You can install Change Manager as an Eclipse plugin. This
installation feature lets Eclipse users add a version of Change Manager
with full functionality to their development environment without
requiring the standalone application.
- Change Manager 6.0 is not compatible as a plugin with Rapid
SQL Developer 2.x and DB Optimizer 2.5.
DB Change Manager 6.0 should be installed in a different
directory than previous versions. If DB Change Manager is installed in
the same directory, the following error will result in at application
start up: "Unable to read workbench state. Workbench UI layout will be
If a previous version is already installed on your machine, either
change the default Workspace or delete all files from the Workspace
directory. The Workspace directory location appears whenever you start
DB Change Manager and can be redefined from this dialog box. If the
same Workspace is indicated for the new version, as was indicated
previously, the following error will result: "Cannot restore workbench
If DB Change Manager is already running, you can also modify
the Workspace directory by choosing File > Switch
Workspace > Other from the Main menu.
The format in which schema comparisons are saved has changed in 6.0.
Use the import feature to import pre-6.0 schema comparison jobs.
DB Change Manager 6.0 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.
NOTE: You do not have to upgrade to 5.6 and then to
6.0. The import procedure is the same.
Upgrading from Version 5.0, 5.1.x, 5.5.x or 5.6 to
All objects can be imported from version 5.0, 5.1.x, 5.5.x or
5.6 to Version 6.0.
To upgrade from 5.0, 5.1.x, 5.5.x or 5.6:
- Make sure that the earlier product is not running and that
no command line jobs are being processed.
- Install and run DB Change Manager 6.0 in a different
directory than the previous installation.
- The Welcome to DB Change Manager dialog
opens with the Setup and Import
data sources, jobs, and settings from a previous version import options
- 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.
- Select the version of Change Manager from which to import.
- 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.
- The wizard imports the items from the previous Change
Manager version. Click Next to continue through
each step of the wizard.
- Click Finish. The jobs are imported to
Upgrading from Version CMSchema 4.0 or CMData/Config
4.0 to 6.0
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
- command line automation (scheduled jobs, batch files, etc.)
Note: 4.0 should remain installed to access any archives and
To upgrade from CM Schema 4.0:
- To import schema comparison jobs from 4.0, obtain and
install cmschema_40_932_upgrade.exe from your
Embarcadero Technologies Support representative.
- 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.
- Follow the steps as described in the previous section,
"Upgrading from Version 5.0, 5.1.x, 5.5.x or 5.6".
- 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
- 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
- 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:
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
- 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
- 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.
- 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
- 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
- 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
- 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.
- 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
- 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
- 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 (v220.127.116.113)
- 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.
Bugs fixed in Change Manager 6.0 include:
||Errors are thrown when you generate a large SQL data
script and paste something into it.
||Comparison Summary contains UTC time - should be
||Schema Comparison Sync script results only show ALTER
statements as if Ignore Permissions option was not enabled
||Incorrect Matching on SQL server when ignore name case
option is checked
||Incorrect matching index when using an archive as
Target for a schema comparison.
||Oracle Data Comparison sends redundant set time zone
calls to the server each time it compares timestamp fields
||Cannot have both a default value specified on a column
and a Default object bound to a column
||Not able to map UDT columns on DATA comparison SYBASE
||Identical tables seen as different when comparing
Oracle AL32UTF8 based tables with default tables
||Different results when running a job from the UI and
command line (Dependencies - object permissions related )
||Invalid extract for foreign keys on SQL server
||Objects with the name BIN are not picked in archive vs.
live/live vs. archive comparisons
