ASYNCIONOMM, Database file ffffssss cannot cccc
MUPIP Error: This indicates that database file has current state ssss (" has ASYNCIO enabled;" or: " has MM access method;") and therefore cannot change to assume change cccc ("enable MM" or "enable ASYNCIO"). MUPIP SET can also issue the same message with the text: "; cannot enable MM and ASYNCIO at the same time".
Action: Address the blocking state - ASYNIO by disabling it, or MM access method by change it to BG before repeating the MUPIP command that produced this error.
