Pass vijava ServiceInstance via rabbitmq or another task queue

Question

I'm trying to create a system where a master will create a connection to vcenter and passes the serviceinstance object to a bunch of performance collectors that can then do their work and exit. My question is what would be the best method to share the SI object? I was thinking of using a messaging queue for the purpose, but I'm not really keen on serializing objects. Is there any other more efficient way?

That SI is only going to work on that vCenter which created the SI. If thats is not going to be a problem for you then simply place the session id on the bus for your workers to pick up then they should be able to create a new SI using the session id.

The first time you connect:

ServiceInstance serviceInstance = new ServiceInstance(new URL("https://vcenter/sdk"),user, passwd, true);
String sessionId = serviceInstance.getServerConnection().getSessionStr();

Next place that sessionId on the bus. Have your worker pick it up and do:

ServiceInstance si2 = new ServiceInstance(new URL("https://vcenter/sdk"), sessionId, true);

The default timeout for that session is like 30 mins IIRC..

Also a little self plugging I would suggest a move from vijava to yavijava. Its a fork I maintain which has added lots of nifty features, and Im even currently adding 6.0 support. https://github.com/yavijava/yavijava
