When running a job to access the Datacom Multi-User Facility (called MUF), the following error message is seen:
DB00501E - OPEN ERROR - RETURN CODE 85 (002)
Release: All supported releases.
This is the description of the RC 85(002) error:
The job has requested XCF access to a remote Multi-User Facility. The job has requested more task areas (by itself) than the TASKS xcfnumber MUF startup option allows.
Increase the value of the fifth subparameter (xcfnumber) of the TASKS MUF Startup Option to handle the number of tasks that will be running in the MUF from remote LPARs. This value will take effect the next time that the MUF is started.
If the MUF cannot be restarted and this value needs to change before then, there is a console command available to version 14.0 and higher that will allow the value to be changed: /f mufstc,TASKS_XCF xcfnumber (where 1 <= xcfnumber <= 4000).
