Issue/Introduction

An IPL hangs  with a DISABLED WAIT state code 08C after setting up the CAISEC00 PARMLIB for ACF2. 

The CAISEC00 method (SYS1.PARMLIB member) of starting ACF2 at IPL time has been implemented as described in the ACF2 TechDoc page Perform ACF2 System Initialization. At the first subsequent IPL sequence, the system hangs, and messages are seen including one saying the disabled wait program status word (PSW) is 0002000080000000000000000000108c.

Here is an explanation for the wait state 08C  reason code 01 (from IBM manual: z/OS System Codes, under Wait State Codes):

08C

Explanation: An error occurred during workload manager (WLM) processing due to recurring abends in the WLM address space. The accompanying hexadecimal reason code identifies an internal, unrecoverable WLM error.

Code Description
001 Wait state/reason code for nonspecific WLM failure. This Wait State code is by the WLM Job Step Tasks Resource Manager Routine as well as the WLM Address Space Resource Manager Routine should IWMINTSK or IWMINJST terminate for any reason

 

Environment

z/OS

Cause

There is no LOGONID for the WLM address space, or it is suspended, AND there is no functional STC default LOGONID to be used instead. This leads to the WLM address space not being able to initialize, which ultimately causes the WAIT STATE with code 08C.

Resolution

Specify a valid LOGONID for the WLM address space, that has the STC attribute, and is functional (not suspended). If the LOGONID assigned to WLM is not functional, then make sure it is updated to be functional, or simply delete this LOGONID provided there is a functional default STC LOGONID in place. Example (in ACF or LID mode):

INSERT WLM NAME(WLM STC) STC NON-CNCL
or
CHANGE WLM NOSUSPEND

If there is no LOGONID assigned for the WLM address space, then the default STC LOGONID is required. Example (in ACF or LID mode):

INSERT ACFSTCID NAME(DEFAULT STC ID) STC NON-CNCL
