Changing the VSAM CI size for a HALDB database data set

You can change VSAM CI sizes for a HALDB database data set only by using z/OS® DFSMS commands. After you change the VSAM CI size, the partition initialization needed (PINIT) flag is set for the partition.

Because VSAM CI sizes are not stored in the DBRC RECON data set, you cannot change them using the HALDB Partition Definition utility (%DFSHALDB) or the DBRC CHANGE commands.

For information about the z/OS DFSMS commands used for VSAM data sets, see z/OS DFSMS Access Method Services for Catalogs.
