Thanks for the info Tom.
Another option I have now is to make a remote call to the DAS to ask for
the property. The in-code equivalent of:
asadmin --host [hostname] get
configs.config.server-config.system-property.GMS_LISTENER_PORT-[cluster
name].value
Can you tell me what the proper way is to do that (if any) from within
the gms-adapter module? Something with RemoteCommand I guess, but you'd
know up front if there are any issues with this approach.
I have the DAS host and admin port already at this point in the code. I
know that it will only work if secure admin is turned on, but I'd at
least like to provide the option. This is something we'd like to get
into 3.1.2 also, if possible, in case that makes a difference.
Thanks,
Bobby
