Recovering the compression dictionary data set without bringing down a Db2 data sharing group
If the compression dictionary data set (CDDS) becomes logically damaged, you need to recover or rebuild it.
About this task
An implementation of the GDPS® Continuous Availability with zero data loss (GDPS Continuous Availability with zero data loss) solution uses a CDDS for the source data sharing group. Before you can recover a CDDS, the CDDS must be closed and deallocated. You can close and deallocate the CDDS without stopping the Db2 data sharing group by issuing the -STOP CDDS command. After you recover the CDDS, you can allocate and open the CDDS by issuing the -START CDDS command.
Procedure
To recover or rebuild a CDDS, follow these steps in the source data sharing group:
