JavaVM Options

Specify additional options to be passed to the JVM loaded by the domain's server processes. Separate the options with spaces, for example:

 -Xrs -Xmx256m -Xms256m

If the domain will run as a Windows service, you must specify at least the default option, -Xrs.

Note:

If you are using the AIX operating system, these options may be required: JavaVM Options=-Xrs -Djava.awt.headless=true -Xcheck:jni.

The JavaVM Options parameter specified in the [PSTOOLS] section specifies global JavaVM options used by every server process in a domain. To override this global value for a particular server process, you can apply custom JavaVM options to individual server processes by adding the JavaVM Options parameter manually to the configuration section for that server process.

JavaVM Options can appear multiple times in a single PSAPPSRV.CFG or PSPRCS.CFG file. While the JavaVM Options value in the [PSTOOLS] section applies to all server processes governed by a particular configuration file, the system only uses the JavaVM Options value in the [PSTOOLS] section for server processes that do not have the JavaVM Options parameter added to its configuration settings section.

For example, if the JavaVM Options parameter has been added to the [PSAPPSRV] section of the PSAPPSRV.CFG file and has been assigned a value, then that value will be used when loading the JVM as a thread of that PSAPPSRV process. If the JavaVM Options parameter does not appear, or has no value, in the [PSAPPSRV] section, then the system uses the value specified in the [PSTOOLS] section when loading the JVM as a thread of the PSAPPSRV process. This applies to any server process: PSAPPSRV, PSQRYSRV, PSAESRV, and so on.

See your JRE documentation for valid JVM options.

Note:

If the server runs behind a proxy server, and Java code will be invoked, you must set the -D Java options to reflect your proxy connection settings. For example, Java code invoked by any Tuxedo-managed server, such as the application server or Process Scheduler server, requires the following Java options: -Dhttp.proxyHost=<value>, -Dhttp.nonProxyHosts=<value>, and -Dhttp.proxyPort=<value>.
