Resolution:
We recommend that you first take a look and follow the instructions in "Post-Installation Instructions" and “Review the Administrator’s Checklist” outlined in chapter 5 “AS/400” of the TIBCO Rendezvous Installation Guide, and the AS/400 readme file that comes along with the installation.

Basically, if you have option 30 of the OS installed, you can use QSHELL by entering qsh on the Command Entry screen, followed by cd /usr/tibco/tibrv/bin tibrvlisten.  Here the messages will appear on the screen.

If you don’t have option 30, you will have to use the Native commands.  Because of the nature of the application having multi-threading, you will have to use batch:

SBMJOB CMD(CALL PGM(TIBRV/TIBRVSEND) PARM('-service' 7500 '-daemon' 'hawk400.na.tibco.com:7500' 'subject1' 'subject2')) ALWMLTTHD(*YES)

Here the messages will appear in a print file.
