Error occurred while trying to connect to Performance Analysis Agent
Details:
Connect to middleware failed Extended Information: Message: Error reported by function Connect.
Component Class: TSCSourceConnection
Error Code: -47 = Connect to middleware failed
Last Error
Code: -47
Cause: Connect to middleware failed (May be the launcher at the middleware-host=mw_hostname is down) - Error Code:-1010101 - Unknown problem. Connect Info: host=monitored_hostname instance=monitored_hostname-SID port=3566 user=@(#)internal_sc_StealthCollect_6.0 extra_info1= extra_info2=
Location: sga_monitor_v250.cxx:523
The Last Error information does not necessarily relate to the last ScapiAccess error message.
CAUSE 1
Client machine cannot resolve hostname of middleware machine. When agent was configured, it was configured with only the unqualifed hostname so if a client machine needs a fully qualified name, it will fail to connect.
CAUSE 2
PA network ports are being blocked.
WORKAROUND 1
1. cd <install_dir>/agents/StealthCollect/6.0/<host-sid>/quest_sc_collector/config/
2. cp -p quest_sc_mw quest_sc_mw.backup
3. Modify the quest_sc_mw file and change the line:
host mw_hostname
to:
host mw_hostname.domain.com
Then save the file. You might need to restart the agent at this point, which you can do by going to <install_dir>/agents/bin and run
./quest_launcher_daemon stop
./quest_launcher_daemon start
or
Here are the steps for Unix machine, restart the PA Processes:
To stop/start the PA processes on the middleware, the user needs to go to 'stealth home/agents/bin' and issue:
./quest_launcher_deamon stop
Restart the launcher:
./quest_launcher_deamon start
Try to connect to PA. If it doesnt work, please restore the original quest_sc_mw file.
WORKAROUND 2
Ensure that all the ports between all the PA components (client, middleware, monitored host) are opened bidirectionally via the firewall. Refer to the PA Agent installation guide or KB article SOL25942 Performance Analysis communication workflow for more information on how the PA components communicate with each other.
