The 'user.home' property is set to the JSM instance system directory. The SystemDefault.properties file located in the JSM instance system directory can be used to set Java system properties.

i5/OS and the JVM determine the values for Java system properties by using the following order of precedence:

  • Command line

  • QIBM_JAVA_PROPERTIES_FILE environment variable

  • user.home SystemDefault.properties file

  • /QIBM/UserData/Java400/SystemDefault.properties

  • Default system property values.

If the first line of the SystemDefault.properties file starts with #AllowOptions, then JVM options and System properties can be used.
