Configuring Additional JVM Parameters
You can define and configure some additional Java parameters that are passed to the JVM when it is started. You define the additional parameters in the wrapper.conf file in the same way you configure memory allocation, as described in Configuring the Java Service Wrapper. Each additional parameter is defined in the form:
wrapper.java.additional.<n>=<parameter>
where:
*<n> is a numeric value, starting with 1 for the first additional parameter, and then incrementing by one for each consecutive parameter.
*<parameter> is the parameter name and value.
*To configure additional JVM parameters
1. Browse to Software AG_directory /optimize/analysis/conf/ and open the wrapper.conf file for editing.
2. Define the most frequently used additional parameters.
The following table describes the additional JVM parameters.
Parameter
Value
wrapper.java.additional.<n>= -Xsssize
256k
Note:
Set this value to 512k for HP-UX 64-bit.
wrapper.java.additional.<n>= -XX:PermSize=value
The default value for PermSize is set by the JVM. In the event of Perm out of memory errors, use this parameter to increase the PermSize value.
wrapper.java.additional.<n>= -XX:MaxPermSize=value
The default value for MaxPermSize is set by the JVM. In the event of Perm out of memory errors, use this parameter to increase the MaxPermSize value.
3. Save the wrapper.conf file.
4. If the Analytic Engine is running, restart it to apply the modifications.
