Answer 1

I had restarted the cacheagent by using the following command
Call ttCacheUidPwdSet();
call ttCacheStart();
Also tried
ttAdmin -oraAgentStart -oraAgentUID test -oraAgentPWD test cgdsn to manually start the Agent.
If I use ttCacheStop() it gives the message the Cache agent has already been stopped.
