JNLRDERR, Error reading journal file xxxx: unable to initialize.
Run Time Error: This indicates that GT.M encountered an error while trying to read from the journal file xxxx. This can happen if the journal file size is less than the minimum size of the journal file header, or if the journal-file-specification does not match the intended file, or if the intended file is not accessible by the processes that update the database. GT.M automatically attempts to create a new journal file. If the attempt to create a new journal file fails, GT.M issues another error and the intended update is lost and does not get registered in the database and journal.
Action: To reestablish durability, perform a MUPIP BACKUP that switches to a new set of journal files.
