gtpo1m3m | Operations |
Use this command to start the database reorganization (DBR) output phase. You can capture the database based on the settings in the master keypoint or set up the override keypoint to capture only part of the database. The partial capture starts when you enter this command with the END parameter.
Requirements and Restrictions
Format
|
You can specify as many as 8 record types. If more than 8 record types are required, enter the command with 8 record types and do not specify the END parameter; then enter the command again with the remaining record types followed by the END parameter. Processing does not begin until you specify the END parameter. If any previous ZDBSO START commands with the rectype parameter specified were entered, these records are also captured.
Additional Information
If you want to run the DBR output phase with buffered tape devices, you must do one of the following:
Attention: Running the DBR output phase with buffered tape devices will improve performance; however, if the system re-IPLs or tape errors occur while DBR is in progress, you may lose data. Also, because the switch that is set by the DBRBUF parameter is subsystem-shared, you can specify ZSYSG with the DBRBUF parameter only from the basic (BSS) subsystem.
Examples
In the following example, DBR is started for 4-KB long-term pool records.

In the following example, DBR is started for record types 0027, 0040, 0046, and 009A in a subsystem with multiple subsystem users.
