The maximum amount of memory (MB) that the service JVM will be allowed to use is controlled by the wrapper.java.maxmemory property, configured in the file
<PT_HOME>/PortletSuiteILotusNotes/3.4/settings/config/wrapper.conf. For example, the following line shows a maximum memory setting of 1 GB:
The setting corresponds directly to the -Xmx parameter used by the java executable. The default value of this setting in the config file is adequate for most configurations. For large production configurations, especially those in which the service is installed on a dedicated host machine, this value should be set as high as possible (for example, 1024 or 1536) but should always remain below the amount of physical RAM on the host machine.
