Hi Sekar,
If I am reading it correctly, you are not able to run multiple deployments from the same end point (remote agent) agent. Right?
If that is the case, you can increase the client and server network threadpool but all it does is it accepts multiple request in agent, nimi_config.xml. PS: You have to increase those in multiple of 2 (Even numbers). 10 means 5 multiple request agent will accept.
Here is the catch, it is not going to solve your multiple deployments requirement. Remote Agent (End point) accepts requests whatever you configured but the agent is going to process one task at a time. With this option, you have achieved multi-threading but not multi-tasking. Agent is going to run one task at a time.
I have created an idea (enhancement request) to get this feature added. RA Agents - High Availability Feature
You can vote for my idea
Also note that even if you set it to utility server or the new requires exclusive execution, it only works for retrieval tasks. It doesn't work for deployments.
Thanks
