Hi Ramakiran,
It is possible for multiple machine definitions to reference a single System Agent within AutoSys. An example of such is below.
/* ----------------- machine1 ----------------- */
insert_machine: machine1
...
port: 7520
node_name: agent_host_name
agent_name: WA_AGENT
...
/* ----------------- machine2 ----------------- */
insert_machine: machine2
...
port: 7520
node_name: agent_host_name
agent_name: WA_AGENT
...
The node_name is the name/IP of the server upon which the agent is installed. If there are multiple agents on the same machine then they will be using different ports.
When you first installed the AutoSys server I suspect that that the first agent was defined. When you uninstalled AutoSys and started afresh, did you also drop the AutoSys database tables? If not, then its possible that the original machine definition remained in place and that during/after the second installation the additional machine was added.
I suggest that you check the definition of both machines to verify that they are referencing the same system agent. Assuming that this is the case, you can use the JIL interface to delete whichever machine you no longer need (delete_machine: ******).
