Configure JVM Tuning for ERPI (FDMEE)
1JVM Tuning
The JVM (Java Virtual Machine) allocates and manages the heap memory based on how much each Java application needs. When a Java application is running, the systematic usage and release of heap memory is managed through a “garbage collector”.
The two settings to change for heap memory are:
-Xms - the minimum size of the heap
-Xmx - the maximum size of the heap
VM Heap Registry Settings in Windows Server
1. Open the Windows Registry.
2. Navigate to below location
3. HKEY_LOCAL_MACHINE\SOFTWARE\Hyperion Solutions\ErpIntegrator(n)\HyS9aifWeb_epmsystem(n) Where ErpIntegrator(n)
4.
5. (ErpIntegrator0, ErpIntegrator1, depending on how many FDMEE web servers are deployed and which server you are updating.
6. Locate the two JVMOptions –Xms and –Xmx (Data Type is REG_SZ).
7. Double click the option to change. (For example, JVMOptionnn)
8. In the Value Data, change the numerical value of –Xms2064m to the new value,
9. Repeat this step for the –Xmx value.
10. Restart the HyS9aifWeb service.
Note: -Xms and –Xmx values should be set to the same number
In Linux Server
To change the JVM heap entries for Linux do the following:
1. Edit this file: /user_projects/epmsystemx/bin/deploymentScripts/setCustomParamsErpIntegrator.sh.
2. Find the section JAVA_OPTS=”-Xms512m –Xmx512m….”
3. Change the numerical values to the new desired heap memory value, save the changes.
4. Restart the “Oracle Hyperion FDM Enterprise Edition - Java Web App” service.
Weblogic Data Sources:
Increase the default number of data sources. WebLogic data sources are the number of pooled connections made available to FDMEE for a JDBC (database) data source.
Tips… for error
If your application runs out of WebLogic data sources you might see in your log file, “ResourceLimitException”, or “Reached maximum capacity of pool”.
To start Oracle WebLogic Server Administration Console:
1. Select Start, then Programs, then Oracle WebLogic, then User Projects, then EPMSystem, and then Start Admin Server for WebLogic Server Domain.
2. When the Admin Server displays “RUNNING”,
3. Select Start, then Programs, then Oracle WebLogic, then User Projects, then EPMSystem, and then Admin Server Console.
4. To access the WebLogic Server Administration Console from the browser type in the following URL: » http://servername:7001/console
5. Login to WebLogic Server Administration Console with the credentials used during the system configuration
6. From Domain Structure, select Services, and then Data Sources.
7. Select either aif_datasource or odiMasterRepository by selecting the hyperlink in the Name column.
8. Select the Configuration tab and then the Connection Pool tab
9. Click Lock & Edit button to modify the “Maximum Capacity” setting.
10. In Maximum Capacity, type the new value for the data source connections.
11. Once the setting is changed, click Save. Repeat steps four through eight to change the odiMasterRepository data source connection pool.
Batch Size:
Specify the number of rows read at a time from the file to memory. This parameter is mainly used for performance.
Batch Size Batch Size refers to the number of import records that are “batched up” before a commit occurs on the database.
The “Batch Size” parameter is set at the system level.
Default setting for “Batch Size” is 1000.
This setting is changed by selecting Data Management, then on the Setup tab, select Configure, System Settings. On the System Settings screen, type the new value in the Batch Size field and click Save.
Smaller imports, such as < 10,000 records, would suffice to use the default batch size. If you have < 100000 records, keep the batch size setting as 10000.
Note: A setting too large or too small can have adverse performance effects.
Oracle Data Integrator (ODI)
ODI has three significant tuning components to explore if you are having problems loading large data sets.
1. Array Fetch Size
2. Batch Update Size (These can be found in “Topology” tab of ODI Studio in the Physical Architecture section for your data server.
3. Maximum number of sessions (The Maximum number of sessions setting is found under the agent.
Tips..
Optimal values for
Array Fetch Size and Batch Update Size is “100” for better performance, low memory and CPU usage.
Open ODI Studio and connect to FDMEE repositories
Go ODI Navigator
Go to Physical architecture à Technologies à Oracle à Data Server ( EBS_DATA_SERVER or FDMEE_DATA_SERVER)
The “Maximum number of sessions” value depends on the capabilities of the machine running the agent. Oracle Data Integrator allows you to load balance parallel session execution between physical agents. Each agent has a maximum number of sessions it can execute simultaneously from a work repository.
The default value for Maximum number of sessions is 1000
