The simplest way for you is probably to run the CHGOUTQ command against the remote *OUTQ name. Change the address in the RMTSYS() parameter. However, a better way is not to use addresses for these; use host names instead. If an address needs to be changed, then change the host entry in the hosts table. — Tom

These are the steps I follwed. But am facing an error
ENDWTR (outq_name)
CHGOUTQ (outq_name)
I changed the IP address.
STRRMTWTR (outq_name)
But am facing the below error.
Post. . . . : The output queue QUSRSYS library FAXPRT is   assigned to another writer.                                                                               Cause. . . . . : The output queue is assigned to another writer.    While the transcriber is of a type that is different from tearing, or   While the number of transcriptionists uprooted to the output queue has   exceeded the limit of 10.Recovery. : Use the WRKOUTQ with OUTQ (* ALL) or mandate   WRKWTR with WTR (* ALL) to display the Transcriber is active for   output queue. Then use the OUTQ parameter to correct the   name of the output queue or use the command to finish ENDWTR   existing transcriptionist
 
I do not understand what the error is…?
 

But am facing the below error.
 
What error? You show the text, but we can’t be sure of the error because you didn’t include the message identifier. It looks like you ran the text through a translator (which is helpful), but translators do not guarantee exact translation. If we had exact translation, we might be able to search through English message files to determine which message ID was involved. If there is a single character that isn’t correct, we won’t find a match.
 
It looks like you ended a writer, but the writer is not the one that is using that *OUTQ. Or the writer did not finish ending before you tried to change the *OUTQ. But we can’t be sure from what we see in your comment.
