Reassign the Java Home Directory

You may want to reassign the Java home directory, for example, when you install a new minor version of Java into a different directory to preserve the old version. When you change the Java directory, you must correct the Java path in the following places:

Change the value of the JAVA_HOME variable In the SAMPLIB(MSMLIB) member.
Example: In the following sample SAMPLIB(MSMLIB) member, replace original_path with the new path.
```
    export JAVA_HOME=original_path
```
Change the SMPJHOME DDDEF value in the CA CSM CSI that points to the Java home directory. The CA CSM CSI is located in CSIHLQ.SMPCSI.CSI. Change the SMPJHOME DDDEF value in the global (GLOBAL), target (CAIT) and distribution (CAID) zones. Use the UCLIN statement to change the SMPJHOME DDDEF value.
Example: Use this UCLIN statement to change the SMPJHOME DDDEF value for all CA CSM CSI zones by replacing the zone variable with each zone name: CAID, CAIT and GLOBAL.
```
    SET
    BOUNDARY(zone).
    UCLIN.
    REP  DDDEF(SMPJHOME)
         PATH('new_path').
    ENDUC.
```

Note: Once you start the MSMTC job, the JAVA_HOME path in the job log message has to match the path in the SMPJHOME DDDEF in the CA CSM CSI:

JVMJZBL1006I JAVA_HOME = new_path

Change the JAVAPATH option in the MSMSetupOptionsFile.properties option file located in the MSMPATH/CEGPHFS directory.
Example: In the following MSMSetupOptionsFile.properties option file sample, replace original_path with the new path.
```
    JAVAPATH=original_path
```
