Steps to change the IP address of the LPAR/System on which CSM is running:
1. Shutdown CSMTC, the DB server and the MUF.
2. Update hostname in SAMPLIB(DBINIT) to use the new IP address.
3. Update hostname in .../msmruntime/dsi/dsi.conf to use the new IP address.
4. Update hostname in the context.xml file located at .../msmruntime/tomcat/conf with the new IP address.
This is an ASCII file so the 'ea' command for edit ASCII should be used.
5. Restart the MUF, DB server and CSMTC.
