The Question is:
Backup reports an error 10A3800A - the message translates into a %BACKUP-E-NOMSG.
Any clues on what it is ?
The Answer is :
To translate error messages, you can use the SET MESSAGE command
and the target message file.
BACKUP messages can be found in SYS$MESSAGE:SYSMGTMSG.EXE.
$ SET MESSAGE SYS$MESSAGE:SYSMGTMSG.EXE
$ WRITE SYS$OUTPUT F$MESSAGE(%X10A3800A)
%BACKUP-E-OPENIN, error opening !AS as input
You would need to examine the log file to find out the file which
caused the error, if this is indeed an input file error.
This type of error can also be produced by incorrect or inadequate
settings among the various process quotas involved; it is possible
that a process quota exhaustion condition can render BACKUP or most
any other utility unable to access the message file to retrieve the
error message text. The quota exhaustion condition could be the
initial error, or it could be secondary to another error.
In the specific case of BACKUP, the recommended process quota
settings -- and the recommended relationships among the various
process quotas -- are available in the System Management manual
within the OpenVMS Documentation Set.
