Options for JVMs in a CICS environment
The options in a JVM profile are used by CICS® to start JVM servers. Some options are specific to CICS, but you can also specify environment variables and Java™ system properties.
Coding rules
When you specify JVM options, make sure that you follow the coding rules. For more information, see Rules for coding JVM profiles.
Format
The format of options can vary:- Options in a JVM profile either take the form of a keyword and value, separated by an equal sign (=), for example
JAVA_PIPELINE=TRUE
, or they begin with a hyphen, for example-Xmx16M
. - Keyword value pairs are either CICS variables such as
JAVA_PIPELINE=TRUE
, or if not recognized as CICS options, they are treated as z/OS® UNIX System Services environment variables, and are exported. - Options that begin with
-D
in a JVM profile are JVM system properties. Options that begin with-X
are treated as JVM command-line options. Any option that begins with-
is passed to the JVM after any substitution symbols have been expanded. For more information, see JVM system properties.
