M204.2581  APF authorization required for XMEMOPT​=​2 (IOS Branch Entry) and XMEMOPT​=​2 required for option

The indicated parameter setting, option, is valid only if IOS branch entry (the X'02' bit in the XMEMOPT CCAIN parameter) is being used. And in turn, APF authorization is required if the XMEMOPT X'02' bit is on.

Possible option values are:

  • SYSOPT2 X'80' bit (XTIOT)

    The XTIOT option might be specified explicitly on a DEFINE or ALLOCATE command or as the default by the SYSOPT2 X'80' bit.

  • NUMBUFG > 0

    Set as a CCAIN parameter.

  • NMPSUBZ > 0

    Set as a CCAIN parameter.

Response: Remove the XTIOT option from the DEFINE or ALLOCATE command, or contact the system manager.

System manager response: If the message is issued during initialization, do one of the following:

  • Remove the X'80' bit from the SYSOPT2 parameter (if the complaint is about the XTIOT option)
  • Set NUMBUFG to 0 (if the complaint is about the NUMBUFG parameter)
  • Set NMPSUBZ to 0 (if the complaint is about the NMPSUBZ parameter)
  • Restart Model 204 with the XMEMOPT X'02' bit, with M204XSVC linked into the Model 204 nucleus, and with the load module APF-authorized.

Message attributes:

RETCODEO=0Sets online return code
RETCODEB=4Sets batch (single user) return code
CLASS=EError class; the message can be suppressed with the X'04' bit setting of the MSGCTL parameter
AUDITERWrites the message with line type ER to the audit trail
COUNTIncrements the error count (ERCNT) parameter
