I would like to be able to specify the Java classpath for a particular execution group's JVM, without affecting other execution groups.
I can't see this option in the mqsichangeproperties (ComIbmJVMManager) command.
Anyone know a way to achieve this?
Can it be done using the jvmSystemProperty option to set a name/value pair? |

Remind me again if you're at Broker v7?
If not, you likely can't. |

| New broker, new workpath, new EG, new Shared-Classes, new CLASSPATH in shell that issues mqsistart... |

| New QM, new HA resource, new WLM class, new filesystem, new DNS alias, new broker userid, new DB2 database and so on - I think not somehow!! |

Well.
There are, of course, other solutions. You can indeed deploy the JARS you need on the CLASSPATH to the EG in question, using a non-message flow BAR file. Then the only EG that has the JARS in it have these classes on their classpath.
You could include a JCN in whatever flow needs these classes, that manually loads the relevant classes.
Neither of these will allow you to *remove* things from the classpath of a given EG.
You can certainly *try* setting -cp using mqsichangeproperties and -n jvmSystemProperty... but that's as likely to cause things to halt and catch fire as not. |

Stick it in a JAR file. Stick that in a BAR file... deploy it.
Or reference it by full path in whatever needs to use it, and put it in a known location on the broker system. |

| There might also be a corresponding -D property that could be set to indicate where the properties file is. Depends, again, on what's using it. |
