What caused the CA Datacom Shadow Multi-User (MUF) startup to terminate with error
DB00205E - MULTI-USER ERROR - 1106 MUFPLEX NUMBER ALREADY IN USE?
1106 means:
Data Sharing initialization failed due to specification of a number parameter on the MUFPLEX MUF startup option that is already in use for this instance of the MUFplex.
Review MUF startup options and ensure that number is unique throughout the MUFplex.
In this case, the Datacom MUF startup parameter SYSPLEX was missing the "S" value in the "mode" parameter which indicates that this is a Shadow MUF environment:
??? MUFPLEX ? name,number ?????????????? ,max_tasks ???????????????????????????
?? ,locks ?? ?? ,mode ??
??????????????????????????????????????????????????????????????????????????????
?? ,tracesize ?? ?? ,mufplex_entry_ratio ??
???????????????????????????????????????????????????????????????????????????????
?? ,mufplex_element_ratio ??
In this case, the Shadow MUF successfully started after the MUF startup option ...
MUFPLEX name,*,,max_tasks
... was corrected to add the ",S" ...
MUFPLEX name,*,,max_tasks,S
