The JobScheduler requires an Oracle Java Runtime Environment (JRE) 32-Bit at least version 1.6.x.
For AIX you can use the IBM Java 32-Bit at least version 1.6.x, too.
You can install the 32Bit Java in parallel to a 64Bit version.
If you start the JobScheduler, it is looking for the Java Virtual Machine, which is normally in ...
- ... %JAVA_HOME%\bin\client\jvm.dll for Windows.
- ... ${JAVA_HOME}/lib/i386/client/libjvm.so for Linux.
If the JVM is not found or is not from above Java environment then you get the error:
terminate called after throwing an instance of 'zschimmer::Xc' what(): Z-JAVA-101 Java Virtual Machine is not started
In this case you must edit the JAVA_HOME variable for the JobScheduler in the ./bin/jobscheduler_environment_variables.(cmd|sh) file.
For Linux:
For example
<span style="color:red;">#</span> test -z "$JAVA_HOME" && JAVA_HOME="/usr/lib64/jvm/java" <span style="color:red;">JAVA_HOME=/opt/jdk.1.6</span>
If necessary, the LD_LIBRARY_PATH must be adjusted too in the ./bin/jobscheduler_environment_variables.sh file.
For Windows:
If necessary, add the location of the Java Virtual Machine to the JobScheduler configuration file .\config\sos.ini like this:
[java] vm = C:/Program Files (x86)/Java/jre/bin/client/jvm.dll
For Red Hat:
Look into the ./config/logs/scheduler.log. If you find an identically line
[ERROR Z-JAVA-100 Java Virtual Machine cannot be loaded [xxx/lib/i386/client/libjvm.so: cannot restore segment prot after reloc: Permission denied] [libjvm.so]]
then you must edit the "Security-Enhanced Linux" settings (see http://fedoraproject.org/wiki/SELinux).
