Change the CICS®-supplied resource definitions in a primary CSD file.
Upgrades the IBM®-supplied definitions in the CSD. Definitions are added to, modified in, or deleted from DFH-groups. Note that deleted definitions are added to compatibility groups with names of the form DFHCOMPn. This enables you to share the CSD with earlier releases of CICS after you have run the upgrade command.
The upgrade command can also be used to apply any package of IBM-supplied resource definitions to the CSD file. For example, the definitions for the CICS sample programs and transactions can be transferred to the CSD file with the UPGRADE statement.
To upgrade a CSD do, not specify the USING operand. All IBM-supplied definitions from any release are deleted and then the CSD file is initialized, so you do not need to say which release you came from.
To install IBM features onto CICS, specify UPGRADE USING(filename). For example, UPGRADE USING(DFHRDJPN) is used to place the double-byte character set feature definitions onto the CSD file.
