Hyperion Planning Java Heap Size

To change the settings for the Planning Java heap size for Web-logic , when Planning is run as a
service or when Planning is started in a command window.

Changing the heap for Planning as a Windows Service:

There are two ways to set the java heap settings for the planning server depending on whether Planning is run
as a service or run in a command window.
Changing the heap for Planning as a windows service
For planning run as a service you need to do the following:

1. Start -> Run -> RegEdit -> Enter.

2. In the registry look for the
HKEY_LOCAL_MACHINE->Software->Hyperion Solutions->HyperionPlanning>HyperionS9Planning.

3. For this node you should see several keys, several are JVMOptions.

4. Locate the Xmx and -Xms which are the maximum and minimum heap respectively.

5. These can be changed by right-click-> and select modify.

6. The recommended settings are 512, and 1024m respectively.

7. Exceeding 1024 is not recommended. Unless you are very familiar with JVM management you should leave all other options unchanged.

8. After changing these two setting you will need to stop and start the Hyperion Planning windows service.
Changing the heap for Planning running in a command window in the foreground.

Changing the heap through command window:

1. Open the start up script, (for example, for Planning:startHyperionPlanningstartHyperionPlanning.cmd or
StartHyperionPlanningStartHyperionPlanning.bat).
2 Add this line to set the heap size (this is an example, your memory choices may be different):
set
MEM_ARGS=-Xms512m -Xmx1024m
before the “call” command.
3. Save the cmd or file

4. If the server was running, stop it using the stop script and start it from the amended start up file.

In 11.1.x.x. :

Open the setCustomParamsHyperionPlanning.bat|.sh location should be  HYPERION_HOME/deployments/app_server/bin/
or  EPM_ORACLE_INSTANCE/bin/deployment scripts/ depending on version) and modify the –Xms128m –
Xmx1024m entry to values of your choice.

If you installed 32-bit Planning on Microsoft Windows 64-bit the registry location is
HKEY_LOCAL_MACHINE->Software->Wow6432Node->
Hyperion Solutions->HyperionPlanning>HyperionS9Planning



Thanks!!

Import Security : Planning

There will be a huge number of requests to grant or remove security access for users. For one or two changes, it is simple task, click on member and then assign access and grant permission. It becomes tiresome when we need to make changes for large number of members. It involves considerable amount of time. Automating the security changes saves considerable amount of time. The ImportSecurity utility in planning loads access permissions for users or groups from a text file into Planning. Importing access permissions using Import security utility overwrites existing access assignments only for imported members, users, or groups. All other existing access permissions remain intact. The SL_CLEARALL parameter clears all existing access permissions. ImportSecurity utility is located at /Hyperion/Oracle/Middleware/user_projects/epmsystem1/Planning/planning1 on Planning server as shown in the following picture: Steps for importing access permissions: STEP1 :Create a text...
