Exporting and importing the repository

To export and import the repository, perform the following process during a quiet time:

1. Perform a LISTCAT of your primary and secondary repository files. Examine the currently allocated space to ensure that the new space allocation will be adequate.

2. Back up your primary repository by executing the following RUVZSM0 utility command:

   SET SUBSYSTEM(<ssid>);
   REPORT(DETAIL);
   BACKUP REPOSITORY
   BACKUP_OUT(<ddn8>)
   ;
3. Bring down your RUV subsystem.

4. Execute the following JCL to export your repository data, delete and define your repository data sets, and repopulate your primary repository data set.

   Note

   Make sure that the Primary and Secondary repositories are the same size. Also note that the CI size has been changed to 2048 (at the recommendation of IBM).

5. Start your RUV subsystem again.
   The RUV subsystem automatically populates the secondary repository from the primary repository at startup.
6. Perform a LISTCAT of your new primary and secondary repository files.
7. Compare the LISTCAT from before and after the export and import process to assess the results of the process.
