M204.0171  A discontinuity was detected for file fileName in update updateID

During the open process for this file, Model 204 detected that another job has updated this file since the previous close. Once a file is opened, Model 204 maintains a copy of the last update date/time stamp in memory. This date/time stamp is also in the FPL that is written out to disk. If a batch job subsequently updates this file, then the date/time stamp in the FPL will differ from the one in memory and this message is issued.

Response: Note the update ID and notify the file manager.

File manager response: If you want to preclude this condition in the future, you can set the FRCVOPT X'10' bit on for this file. You can reset this option at any time or it can be set at the time of file creation.

System manager response: You can open all of your production files in User 0, and close them when you receive an EOD command. This is another method of preventing discontinuities caused by other updating jobs.

Message attributes:

RETCODEO=0Sets online return code
RETCODEB=0Sets batch (single user) return code
CLASS=IInformation class; the message can be suppressed with the X'02' bit setting of the MSGCTL parameter
