Backing up the IMSRSC repository
Consider backing up the IMSRSC repository data sets, so that the IMSRSC repository can be restored.
By backing up the IMSRSC repository data sets, IMSRSC repository can be restored in the following conditions:
- IMSRSC repository error
- Falling back from a new IMS release that changed the IMSRSC repository format
- Backing off maintenance that changed the IMSRSC repository format
The IMSRSC repository consists of a minimum of 4 data sets:
- Primary repository index data set (RID)
- Primary repository member data set (RMD)
- Secondary repository index data set (RID)
- Secondary repository member data set (RMD)
Use IDCAMS to back up either the primary RID and RMD pair, or the secondary RID and RMD pair. Consider using a naming convention for the IMSRSC repository backup data sets to help tie them together to indicate that they belong to one IMSRSC repository.
