IBM Java 7 and VIO Server Release 3.1

How To


Summary

Starting with releases 2.2.6.51 and 3.1, IBM Java 7 can be removed from the Virtual I/O Server.

Objective

This document will describe information about VIOS 3.1 as PowerVM V2.2 is no longer supported since 30th Sept 2020.
VIOS 3.1 release removes the dependency on Java 7 from many filesets.

If you would like to remove these filesets, and Java 7 itself, which goes out of support in July 2022, you can use the following command:
$ updateios -remove_outdated_filesets
Currently, "remove_outdated_filesets" will also remove perf.analysis, hence breaking part command.
We recommend removing Java 7 filesets individually as mentioned in "Steps" paragraph till FIX availability
IBM Java 8 has been included in these releases and must not be removed.
Note: 
  • There is a PATH environment variable in /etc/environment which indicates the default Java to be used on the system.  
  • The PATH does not change automatically. It needs to be changed manually. i.e. If you want default Java on the system to be 64-bit Java 8, you need to remove any old references to Java from the path and add the 64-bit Java 8 entries to the PATH.
  • Option "-remove_outdated_filesets" from updateios command removes the following Java filesets: Java5.sdk, Java6.sdk, Java7.sdk,Java7_64.sdk, Java7.jre, Java7_64.jre

Steps

Summary of the steps to remove the Java7 filesets:

*) Get the fileset name
# lslpp -hac | grep -i java7
*) Check if there are Dependents
# lslpp -d Java7.rte
# lslpp -d Java7_64.rte
*) Remove the fileset
# installp -ug Java7.rte
# installp -ug Java7_64.jre
Details output of these remove :
