IBM InfoSphere Guardium CAS not working with Java version 1.7 on windows

Resolving The Problem

1- find the path where Java 1.7 is installed on your system (ie. C:\Program Files (x86)\Java\jre7\bin\ but it may be different on your system).


2- find the location of the library jvm.dll within the java path found in the previous step (ie. C:\Program Files (x86)\Java\jre7\bin\jvm.dll or C:\Program Files (x86)\Java\jre7\bin\server\jvm.dll but may be in different location under the java installation directory). Copy the complete path.


3- Edit the cas.cfg file in <CAS directory>\conf directory ( ie. C:\Program Files (x86)\GUARDIUM_STAP\cas\conf\cas.cfg)


4- Find the line (usually at the end of the file) corresponding to the JVM, ie. it will look similar to this:

;JVM=c:\program files\java\jre1_2_3\bin\client\jvm.dll

and do this:

a) set JVM to the path of the libray jvm.dll that you found in step 2-
b) uncomment the line if commented (ie. take the semicolon out from the beginning of the line)

For example, if the line looks like this:

;JVM=c:\program files\java\jre1_2_3\bin\client\jvm.dll

you would change it to something like this, assuming C:\Program Files (x86)\Java\jre7\bin\server\jvm.dll is the path to the jvm.dll library:

JVM=C:\Program Files (x86)\Java\jre7\bin\server\jvm.dll


5- Copy 'msvcr100.dll' from the bin folder in your java 7 installation directory to your <CAS directory>\bin folder (ie. copy C:\Program Files (x86)\Java\jre7\bin\msvcr100.dll to C:\Program Files (x86)\Guardium\GUARDIUM_STAP\cas\bin\msvcr100.dll) .

This is only needed for Java version 1.7. For older versions of java this step is not needed. The reason is that in version 7 Java the jvm.dll has a dependency on this msvcr100.dll which was not the case with older java versions.


6- Restart the CAS (Change Audit System) sevrice in control Panel / Administrative Tools / Services
