Appendix D. Profile Property Resolvers

Abstract

When defining properties for a profile, you can use a variable substitution mechanism, which has the general syntax ${ResourceReference}. This variable substitution mechanism can be used in any profile resource, including the agent properties, PID properties, and other resources—for example, the mq-base profile's broker.xml resource references the ${broker.name} and ${data} variables.

System properties can be substituted in a profile resource, using the following syntax:

Where PropName can be the name of any Java system property. In particular, Java system properties can be defined in the following locations:
  • The etc/system.properties file, relative to the container's home directory.
  • System property settings in the profile's agent properties.
Some of the more useful system properties defined in the etc/system.properties file are, as follows:
