REN Server Ports on Multi-App Installations February 7, 2008

Posted by Duncan in Administration, Infrastructure, Oracle, PeopleSoft, PeopleTools, PS Admin.

When you have more than one App Server on a single machine – and they both need to run a Ren Server process – you need to adjust the port number in the same way you do for other processes (although the REN Server is easy to miss – like I did – as it’s near the bottom away from the other port numbers).

If you do boot the App Server without changing the port you’ll get an error message:

exec PSRENSRV -A -- -C psappsrv.cfg -D PADMO -S PSRENSRV : CMDTUX_CAT:1685: ERROR: Application initialization failure

tmboot: CMDTUX_CAT:827: ERROR: Fatal error encountered; initiating user error handler

tmshutdown -qy

OK, you think. I know what that is, it must be a port clash. So you reconfigure the port in PSADMIN and then try to boot it again. Same error. Checking the REN Server log gives the following clue:

(ERROR) nssock: Cannot listen on port 7180. The port may already be in use.

It’s still looking on port 7180, not the new port!

The missing step is to update the database, as the port is stored there also:


You should then find you App Server and Ren Server boot fine.

Hello Duncan,

I saw your post dated 7-Feb-2008 on REN Server related error

We are trying to setup an ERMS system (PeopleSoft CRM9) at our place.While trying to configure REN server using psadmin utility from linux machine, we are getting the same error i.e CMDTUX_CAT:1685: ERROR: Application initialization failure

I tried to boot the system agauin after changing the port numbers.But the error is still the same. Can you throw some light on what could be the possible failure reason be?

Also, If you have any ERMS setup document made by you that gives a basic step-by-step approach right from server setup to creation of simple worklist, agents etc, It will be very handy

I think I’ve getting at the same err when I try to boot the 2nd domain, and I ‘d try to change the port number as you write(it’s reconfirmed), but the error keep just the same as before, even the port number 7180 in the PSRENSRV_xxxx.LOG dosn’t changed. and it the same even after cold reboot the server(It’s win2003server on PC).
Is there any other place have to change or some cach to clear?

Thank you very much.
