Before migrating the data from the Sybase database to Oracle database, do the following:
Ensure that the license state of ZENworks is Active. The product must be installed and running either in the licensed version or the evaluation version.
Ensure that the Oracle database is installed on a device that does not have ZENworks installed.
Ensure that the "USERS"/USER-CREATED tablespace has sufficient space to create and store the ZENworks database schema. The tablespace requires a minimum of 100 MB to create ZENworks database schema without any data in it and an appropriate additional space depending upon the size of the database to be migrated. For more information on tablespaces, refer to the section ZENworks Server Installation Guide.
Ensure that the NLS_CHARACTERSET parameter is set to AL32UTF8 and the NLS_NCHAR_CHARACTERSET parameter to AL16UTF16 by running the following query at the database prompt:
select parameter, value from nls_database_parameters where parameter like '%CHARACTERSET%';
Ensure that the, , and do not contain blank strings in the NC_VRBSOFTWARE table. In case these column have blank strings, delete those records from the table. Deleting these records will remove the usage of these software from database.
Query to delete the records from:
DELETE FROM NC_VRBSOFTWARE WHERE SHARENAME='' OR PATH='' OR FILENAME='' OR SHARENAME IS NULL OR PATH IS NULL OR FILENAME IS NULL;
(Conditional) If you want to migrate the database by creating a new user schema, ensure that the following additional requirements are met:
You must be aware of the database administrator credentials.
NOTE:Ensure that the database administrator has the following privileges:
GRANT ALL on DBMS_REDEFINITION with GRANT option;
GRANT ALL on DBMS_DDL with GRANT option;
A tablespace must already exist for associating to the Oracle access user
You can choose to migrate the database by using an existing user schema that resides on a server in your network in the following scenario:
The database administrator create two user schemas with the necessary rights and you get the credentials for both user schemas from the database administrator. In this case, the database administrator credentials are not required to migrate the database.
If you want to migrate the database by using an existing user schema, ensure that the following additional requirements are met:
Ensure that the user schema has the following rights to create the database.
Ensure that the quota for the user schema is set to Unlimited on the USERS tablespace.
Manually stop the ZENworks services running on the ZENworks Servers in the Management Zone. For more information, see Step 2.a in the Backing Up the Embedded Sybase SQL Anywhere Database on a Windows or Linux Server.
Ensure that your external Sybase database service is running.
(Optional) The status of database migration is logged into the novell-zenworks-configure.log file. By default, only the messages of the type Info and Severe are logged. If you want other message types (such as Finer, Finest, and Warning) to also be logged into the file, do the following in the novell-zenworks-configure.properties file:
Set the value of Logger.logLevel to the appropriate message type.
For example, if you want messages of the type Finest to be logged:
#Logger.logLevel = FINEST
Uncomment the line by removing the “#” as follows:
Logger.logLevel = FINEST
The novell-zenworks-configure.properties file is located in %ZENWORKS_HOME%\conf\ on Windows and in /etc/opt/novell/zenworks/ on Linux.
