IMPORT DEFN SOURCE(CATALOG) command enhancements

The IMPORT DEFN SOURCE(CATALOG) command has new options: NAME and NOCHECK.

NAME option

The IMPORT DEFN SOURCE(CATALOG) command is enhanced to support the NAME() keyword to allow you to specify one or more DBDs or PSBs or both to be imported by name instead of importing all of the DBD and PSB ACBs from the staging directory.

The function is enabled when the new OPTION(NAME) is specified in the IMPORT DEFN SOURCE(CATALOG) command.

All the resources associated with the database DBD or program PSB resources (or both) that are specified on the NAME() keyword are also imported, except for GSAM. For GSAM DBDs and PSBs, only the named GSAM DBDs and PSBs are imported.

NOCHECK option

The IMPORT DEFN command can be used to import changed DBD members with no associated PSB members that are rebuilt by using the DFS3UACB utility with BLDPSB=NO or by using DDL ALTER. The IMPORT DEFN command with the NOCHECK option improves performance to import database changes for the BUILD DBD especially for a catalog directory with large number of members.

The function is enabled when the new OPTION(NOCHECK) is specified in the IMPORT DEFN SOURCE(CATALOG) command.
