ODBM Security Options Enhancement

In IMS 15.3, the ODBM security options enhancement added a parameter, ODBMSECURE, to the IMS control region.

You can use the ODBMSECURE parameter to specify whether IMS performs security checking on a PSB resource for an ODBM thread at the time of the allocate PSB (APSB) request.

The ODBMSECURE parameter can be specified in either the DFSCGxxx member, or the DFSDFxxx member section <SECTION=COMMON_SERVICE_LAYER>. If you specify ODBMSECURE in both the DFSCGxxx member and the CSL section of the DFSDFxxx member, the values specified in the DFSCGxxx member override the values specified in the DFSDFxxx member.
