Oracle hyperion Performance Tuning: Changing the Heap Size in Windows

To change the heap size of a managed server:

For Windows machines, use Windows Registry Editor to change the heap size of the Windows service:

On the machine hosting the product whose managed server you want to modify, open Windows Registry Editor: Select Start and then Run, enter regedit, and then click OK.

In Registry Editor, select HKEY_LOCAL_MACHINE, then SOFTWARE, then Hyperion Solutions, then ManagedServerName, and then WindowsServiceName_InstanceName.

For example, if you deployed a single managed server, select HKEY_LOCAL_MACHINE, then SOFTWARE, then Hyperion Solutions, then EPMServer0, and then HyS9EPMServer_InstanceName.

If you scaled out a single managed server, on the scaleout machine, select HKEY_LOCAL_MACHINE, then SOFTWARE, then Hyperion Solutions, then EPMServer1, and then HyS9EPMServer_InstanceName.

For example, if you deployed Oracle Hyperion Planning, select HKEY_LOCAL_MACHINE, then SOFTWARE, then Hyperion Solutions, then Planning0, and then HyS9Planning_InstanceName.

Right-click JVMOptionX (where X is 1, 2, ...) whose value starts with -Xmx, and then select Modify. In Value data, change the value to a value appropriate for your environment.
-XmxValuem

For example, to set the heap size to 8 GB, enter the following:
-Xmx8192m

Start EPM System by selecting Start, then All Programs, then Oracle EPM System, then Foundation Services, and then Start EPM System.

Complete these steps for each managed server on each machine in the deployment.
