Changing HALDB data set name prefixes

The data set name prefix for each partition is stored in the RECON data set. You can change it using either the HALDB Partition Definition utility (%DFSHALDB) or the DSNPREFX(string) parameter of the DBRC batch command CHANGE.PART.

If you change a data set name prefix, the partition initialization needed (PINIT) flag is set for the partition.
