Changing the JRE Package in Control-M/EM

This procedure describes how to change the JRE package from the default installation to a custom package in Control-M/EM.

You can install the supported JAVA Runtime Environment and replace the one that is installed by default. BMC verifies major releases of JRE provided by Oracle and Azul only if you have a third party support agreements. The use of JRE is supported only where the major release version is the same as the tested version.

To change the JRE package:

1. Do one of the following:
   • UNIX: Do the following:
     1. Create the em_env_local.sh file in the $EM_HOME/etc/directory
     2. Define an alternative Java home directory by adding the parameter BMC_JAVA_HOME to the file em_env_local.sh that is located in the $EM_HOME/etc/directory.
     3. Insert the following lines to the file under the line: ############ A D D I T I O N ##############:

        BMC_JAVA_HOME={new JRE Path}

        export BMC_JAVA_HOME

        CUR_BMC_JAVA_HOME=$BMC_JAVA_HOME

        export CUR_BMC_JAVA_HOME

        if [ -z "$LD_LIBRARY_PATH" ]; then

        LD_LIBRARY_PATH="./:/usr/openwin/lib:$EM_HOME/lib:/usr/local/lib:/usr/lib:$CUR_BMC_JAVA_HOME/lib/amd64/server"

        else

        LD_LIBRARY_PATH="./:/usr/openwin/lib:$EM_HOME/lib:/usr/local/lib:/usr/lib:$CUR_BMC_JAVA_HOME/lib/amd64/server:${LD_LIBRARY_PATH}"

        fi

        if [ -n "${LD_LIBRARY_PATH_64:-""}" ]; then

        LD_LIBRARY_PATH_64=${LD_LIBRARY_PATH}:${LD_LIBRARY_PATH_64}

        else

        LD_LIBRARY_PATH_64=${LD_LIBRARY_PATH}

        fi

        export LD_LIBRARY_PATH

        export LD_LIBRARY_PATH_64

   • Windows: Do the following:
     1. Create the environment variable BMC_JAVA_HOME and set its value to the location of the new JRE.
     2. Add %BMC_JAVA_HOME%\bin\server to the beginning of your PATH system environment variable.
2. Copy the following jar files from {Installation CD Image}\Setup_files\3RD\JRE_libs to {BMC_JAVA_HOME}\lib\ext:
   • bc-fips-1.0.1.jar
   • bcmail-fips-1.0.1.jar
   • bcpg-fips-1.0.1.jar
   • bcpkix-fips-1.0.1.jar
3. Recycle Control-M/EM components.
