Changing the high-level qualifier for Db2 data sets

The high-level qualifier for Db2 data sets is the catalog name of the integrated catalog facility, which is commonly called the user catalog.

Before you begin

To concentrate on Db2-related issues, this procedure assumes that the catalog alias resides in the same user catalog as the one that is currently used. If the new catalog alias resides in a different user catalog, see DFSMS Access Method Services Commands for information about planning such a move.

If the data sets are managed by the Storage Management Subsystem (SMS), make sure that automatic class selection routines are in place for the new data set name.

About this task

You cannot change the high-level qualifier for Db2 data sets by using the Db2 installation or migration update process. You must use other methods to change this qualifier for both system data sets and user data sets.

The following procedures do not actually move or copy data.

Changing the high-level qualifier for Db2 data sets is a complex task. You should have experience with both Db2 and managing user catalogs.
