XCOMS8000E ERROR ACCESSING TRANSMISSION QUEUE when Sending to CA XCOM for I5/OS (AS/400).
CA XCOM Data Transport on AS/400 cannot get Access to the Queue File. If this error happens at regular intervals, it is most likely due to a backup being run at that time, so CA XCOM Data Transport was unable to access the queue file
Other less likely causes of this message are:
CA XCOM Data Transport must be down when a full backup is being done which includes the whole XCOM2 library (or whatever the CA XCOM Data Transport library is named). Change the backup to a time when CA XCOM Data Transport is not actively transferring files or perform the backup at a time when CA XCOM Data Transport is not running.
This is a fatal error and will not be retried. The transfer(s) need to be resubmitted from the sending side.
