| RDBMS table and index repository procedure (OP)With this procedure, you can convert the [RDBMS]_storage file from the runtime data dictionary to the RDBMS Administration
module. During the conversion process, the [RDBMS]_storage file is split up into two separate files: - The database storage parameter file,
[RDBMS]_storage_param - The database driver parameter file,
[RDBMS]_driver_param
If you split up the [RDBMS]_storage file, the interaction between LN and the database is
improved. For example, the time required to run a query reduces. Warning: The information in the Table and Index repository
affects the data transfer to the database. Ensure to store the correct
information in the repository to ensure that you do not corrupt the data
transfer. To optimize the table and index repository: Step 1. Convert the table and index repository.Complete these steps: - Start the Convert Table and Index Repository (ttdba0540m000) session.
- Convert the table and index repository. During the
conversion process the
[RDBMS]_storage file is split up into the [RDBMS]_storage_param file and the [RDBMS]_driver_param file.
Splitting up the [RDBMS]_storage file into two separate files is a once-only action. After you split up
the [RDBMS]_storage file, the file still exists, but has expired; therefore the file is no
longer used. The next two steps are for maintenance purposes of the [RDBMS]_storage_param file and the [RDBMS]_driver_param file. Step 2. Optimize the storage parameters.Complete these steps: - Start the Storage Parameters Optimization (ttdba0132m000) session.
- Use this session to maintain the
[RDBMS]_storage_param file, which is a part of the [RDBMS]_storage file.
Step 3. Optimize the driver parameters.Complete these steps: - Start the Driver Parameters Optimization (ttdba0137m000) session.
- Use this session to maintain the
[RDBMS]_driver_param file, which is a part of the [RDBMS]_storage file.
