Applying an Update Prerequisite Tasks

Before applying the update to move to Oracle Enterprise Performance Management System Release 11.2.7:

Stop services:
- EPM System services
- Node Manager Windows Service and Oracle HTTP Server, if you are using Oracle HTTP Server as your web server
- WebLogic Administration Server
For information about stopping services, see Starting and Stopping EPM System Products.
Back up these folders:
- EPM Oracle Home. The default EPM Oracle home location is MIDDLEWARE_HOME/EPMSystem11R1.
- EPM Oracle Instance. The default location for the EPM Oracle Instance is MIDDLEWARE_HOME/user_projects/epmsystem1.
You can delete these folders after you apply the update and validate the installation.
If you are using Oracle Hyperion Financial Data Quality Management, Enterprise Edition, before applying the update to Release 11.2.6, you must grant permissions on the SYSTEM.schema_version_registry table as sys user using the following command:
```
grant all on SYSTEM.schema_version_registry to <FDMEE_SCHEMA_USER>;
```
If you are applying the update to Release 11.2.6, and you are installing to a drive other than drive C, you must enable Windows long paths before applying an update. This step is not required if you are applying the update directly to Release 11.2.7.
