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:
