Configuring JVM Memory Allocation
The following table provides information about setting the initial and maximum memory allocation for the JVM at startup.
Property
Value
wrapper.java.initmemory
Initial size (in MB) of the Java heap. For the Analytic Engine, the recommended value is 100
Note:
If you specify a value for the wrapper.java.initmemory memory property, make sure that it is smaller than the value of the wrapper.java.maxmemory property.
wrapper.java.maxmemory
Maximum size (in MB) to which the Java heap can grow.
For Analytic Engine, the recommended value is 900.
To use the default values that are configured in the JVM itself, specify zero (0) in the properties of the wrapper.conf file. If you configure the memory amount in the Java wrapper (a non-zero value), the wrapper adds an appropriate -Xms parameter. However, if you configure the default JVM memory amount (a zero value), you can set the -Xms parameter manually as an additional property in the configuration file.
