ZDBRO INIT-Initialize Database Reorganization Control Records

Use this command to initialize the control records that are used for database reorganization (DBR).

The DBR control records can be initialized to allow the capture of all fixed file and pool records in the system. Alternatively, the DBR control records can be initialized so that specific subsystem user, processor, and I-stream combinations are captured.

Requirements and Restrictions

Format




ssu/processor/istream
is a triplet that specifies the subsystem user, processor, and I-stream combination. The specified I-stream is a decimal number from 1 to 16. This parameter captures all the records the specified subsystem user owns for that particular combination.

BYPASS
specifies whether or not to override the control bit that is set to prevent the reinitialization of control records. Specify YES to reinitialize the control records before running DBR.

Attention: Use the BYPASS parameter with care because it reinitializes all DBR records regardless of contents. Using this parameter can cause loss of data that was previously entered by the installation. Any previous values that were set with other DBR commands are overwritten.

Additional Information

After initialization, you can use other commands associated with DBR to specify what sections of the database should not be captured during a DBR run.

Examples

In the following example, the control record is set to capture all the records owned by the SSU1 subsystem user on processor B and I-stream 2.
