Issue:

A Datacom batch job is failing with Datacom RC 68(001) and the following messages:

DB00121I - UNAVAILABLE - mufname                     
DB00122I - ACCESS TYPE - LOCAL    TASKS=1            
DB00123I - WAITING FOR MUF AVAILABILITY

DB10045E - ABNORMAL TERMINATION DUE TO ERROR(S)                        
IEF450I jobname stepname - ABEND=S000 U0004 REASON=00000000  692          

Environment:

z/OS

Cause:

The submitted job was executing on a different lpar in the SYSPLEX than the Datacom Multi-user (MUF) was running and enabled on.

In this installation, it was intended that all jobs be restricted to be run on the same lpar as the MUF and the use of XCF was not desired. 

Resolution:

Add JCL /*JOBPARM statement with SYSAFF= parameter to ensure the conversion and execution of the job will be done on a specific lpar.  

If submitting the job from a remote lpar, supply the specific execution lpar identity:

   /*JOBPARM SYSAFF=lpar-to-execute

When the job is submitted from the same lpar as the MUF, add SYSAFF=* to force execution on the submit lpar:

   /*JOBPARM SYSAFF=*

Additional Information:

Refer to IBM documentation on JCL /*JOBPARM statement and parameters.
