DL1B—PSB and DBD Security

Valid on z/OS.

Use the DL1B control option to:

• Implement PSB and DBD security for IMS batch regions
• Provide access to the CA Top Secret Application Interface Program

This option does not apply to IMS, BMP, or MPP regions and to IMS/DC transactions for which PSB and DBD security is automatically applied through the IMS control region.

All entry methods are accepted.

This control option has the following format:

DL1B(YES|NO)

YES

Indicates that PSB and DBD security checking is implemented in IMS batch regions. The CA Top Secret Application Interface is available to user programs executing in the IMS batch region.

NO

(Default) Indicates that PSB and DBD security checking is suppressed when executing IMS batch regions. The CA Top Secret Application Interface is not available to user programs executing in a batch region. This control option defaults to NO because most installations do not want to implement their BATCH DL1 security concurrent with their IMS/DC security.
