Problem:

I am getting a DISABLED WAIT state with code 08C when trying to start ACF2 with the CAISEC00 PARMLIB member. What is wrong?

 

Description:

I am trying to establish the CAISEC00 method (SYS1.PARMLIB member) of starting ACF2 at IPL time.

I have followed all the instructions given in the ACF2 Installation Guide, Chapter 3, Step 11.
I included ACF2(00 START) in the CAISEC00 member, and there exists a member CAIACF00 in SYS1.PARMLIB.

Very shortly after the IPL sequence, the system hangs, and we see these messages:

Central processor (CP) 0 is in a non restartable wait state (stopped) due to a System Control Program (SCP) initiated reset of the I/O interface for partition SYTC. <== Note: partition id can vary by site
The disabled wait program status word (PSW) is 0002000080000000000000000000108c.

Here is an explanation for the wait code 08C (from IBM manual: MVS 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.

CodeDescription
001Wait 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

Reason for the error:

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
