Cause
The failure of the OPEN ACB for the VTAM control point (CP), as indicated by message IST049I, prevented VTAM from initializing. The hexadecimal code 72 displayed in message IST1218I is a value returned by the OPEN macro indicating that the reason for the OPEN ACB failure is that either VERIFYCP=REQUIRED or VERIFYCP=OPTIONAL was coded in the VTAM start option list, but one or more of the following prerequisites for those start options was not satisfied:
- The security management product is installed.
- The security management product is active.
- The security management product resource class APPCLU is active.
- The application represented by the ACB is in the security management product Started Procedures Table.
Resolving The Problem
If you want to have either VERIFYCP=REQUIRED or VERIFYCP=OPTIONAL in your VTAM start option list, ensure that all of the above prerequisites are met. Doing so will eliminate the OPEN ACB error indicated by messages IST049I and IST1218I.
If, on the other hand, you do not want to have either VERIFYCP=REQUIRED or VERIFYCP=OPTIONAL in your VTAM start option list, either replace VERIFYCP=REQUIRED or VERIFYCP=OPTIONAL with VERIFYCP=NONE, or let VERIFYCP default to NONE.
