Modifying JVM Properties of a Host Through the CLI

Procedure

  1. Navigate to admin sample folder of CONFIG_HOME or TIBCO_HOME.
  2. Add the details of the Host to be modified in host_data.xml.
  3. Add the attribute jvmArgs to the <Host> tag of host_data.xml. This attribute is case-sensitive. Provide all the JVM-specific or user-specific properties within quotes as shown in the below example.
  4. Add the attribute options="mergeJvmArgs" to the update target of host_build.xml to merge the specified JVM properties with the existing properties.

Example: Host_build.xml 

<target name="update">
         <AMXAdminTask
            remote="true"
            propsFile="${instanceProperties}"
            action="edit"
            dataFile="${dataFile}"
            objectSelector="Host"
            overwrite="true"
            merge="true"
            createIfNotExists="true"
            force="true"
            options="mergeJvmArgs"
            failOnError="false"/>
</target>

Example: host_data.xml 

<Host xsi:type="amxdata:Host"
         name="SecondHost"
         description="Description for SecondHost"
         hostType="TibcoHost"
         sourceHost="SystemHost"
         windowsService="true"
         jvmArgs="-Xmx512m -Xms128m -XX:+HeapDumpOnOutOfMemoryError -Dprop1=value1"
         managementUrl="service:jmx:jmxmp://localhost:36923" assignToEnvs="ALL">
