Typically, APARs are not cumulative, because each APAR corresponds to fixes for a subset of Java5 filesets. Different APARs can have different subsets of Java5 filesets. However, the individual Java5 filesets will contain cumulative fixes. Check the version.release.modification.fix (vrmf) number to compare fileset levels. For example, the fixes in fileset 5.0.0.225 contain or supercede the fixes delivered in fileset 5.0.0.210 and below.
How do I know if I have installed the latest code?
There are different ways to determine the level of code on your system:
You can check and compare the build date of your Java installation by using the command: /usr/java5/jre/bin/java -fullversion
You can check to see if a particular APAR is installed on your system by using the command: instfix -ivk APAR_NUMBER
You can check the Java5 filesets installed on your system by using the command: lslpp -L | grep Java5. The list produced by this command might show filesets that are optional, such as java5.samples or java5.source. The java5.sdk fileset is the only fileset you need.
