The maximum size of OSAM data sets and HALDB databases

You set the maximum size of the OSAM PHDAM and PHIDAM data sets for a HALDB database in the RECON data set.

The maximum size of OSAM PHDAM and PHIDAM data sets for a HALDB database can be 4 or 8 gigabytes. When a HALDB database supports 8-GB OSAM data sets, the HALDB online reorganization (OLR) function cannot be used to reorganize the database. Instead, use offline utilities for database reorganization or use 4-GB OSAM data sets, which supports OLR.
