How to change the middleware IP address and hostname from the machine in Performance Analysis ?

How to change the Performance Analysis (PA) middleware IP address and the hostname?

There are two configuration files: quest_sc_mw and quest_sc_mw.cfg.

1. Stop Performance Analysis on the database server and middleware server
   
2. File quest_sc_mw
   
   
   • On monitored host go to (PA_agent_install)/agents/StealthCollect/6.0/(host-sid)/quest_sc_collector/config
   • Make a backup copy of the file quest_sc_mw
   • Open the file and replace the old hostname/IP with the new one
      

3. File quest_sc_mw.cfg

   • On middleware host go to (PA_agent_install)/agents/StealthCollect/6.0/(host-sid)/quest_sc_mw/config
   • Make a backup copy of the file quest_sc_mw.cfg
   • Open the file and search for the old hostname/IP and replace it with the new one

4. If you have the repository database on the middleware server you also need to modify the following files

   • On monitored host go to (PA_agent_install)/agents/StealthCollect/6.0/(host-sid)/quest_sc_collector/config
   • Make a backup copy of the file quest_sc_rep
   • Open the file and replace the old hostname/IP with the new one
   • On middleware host go to (PA_agent_install)/agents/StealthCollect/6.0/(host-sid)/quest_sc_rep/config
   • Make a backup copy of the file sc_rep_mngr.xml
   • Open the file and search for the old hostname/IP and replace it with the new one

5. Start Performance Analysis on the database server and middleware server
   

If only the MW host name changed and nothing else, then this solution should work. The PA services should be stopped on both tiers and the modifications to the files should be made. Once the quest_sc_mw file on Mon Host is modified, the Collector process will look for the MW host in this file. Similarly, the MW process will look for the Collector process on the host as in the quest_sc_mw.cfg file. If the two find each other, the agent will work fine. Obviously the firewall on ports on the said hosts should be set up properly, if there is one. And the other critical thing is the Mon.Host – DB_name (HOST-SID) combination should not have changed at all, as all files carry this HOST-SID combination. But MW hostname change can be easily adapted to, using the quote SOL (provided that is the only thing that is changed and PA install folder pathname has not changed). This applies for 7.0.4 version too.
