Updating Internal Essbase References to a Rehosted Essbase Server

You must map Essbase Server names to cluster names before you perform this step. See Mapping Essbase Server Host Names to Cluster Names.

If the Essbase Server host has changed since the earlier release, you must update internal references to the host. This step updates partition definitions and alias locations.

To update internal references to a rehosted Essbase Server:

From a command prompt on the machine hosting Essbase, navigate to the following directory: EPM_ORACLE_INSTANCE/bin/upgrades.
Run the following script, and then enter the administrator password when prompted:
```
EssbaseUpdateEssbaseServer.bat|sh newHost:port userName 
```
Where newHost is any alias or fully qualified name or IP address for the upgraded machine and userName is an Essbase administrator user provisioned in Release 11.1.2.1. The default port is 1423.
The utility updates the host for all location aliases and partition definitions for all Essbase applications.
Repeat for each Essbase Server instance.

Review the log file, EPM_ORACLE_INSTANCE/diagnostics/logs/essbase/EssbaseRehost.log, for details of the script actions.

If you are configuring all Essbase products at one time, continue to the next section. Otherwise, when you are done with this step, return to the Upgrading Checklist.
