Connection Manager Problems
This section provides suggested solutions for some common problems related to the use of Connection Manager.
CMAN Refuses to Start
Symptom
You issue a CMCTL START command to start Connection Manager, and you receive the following messages:
ADMIN Status: (STATUS=(VERSION=8.1.6.0.0)(STARTED=26-SEP-2000 10:27:37)(STATE=RUNNING)) Failed to start service, error 0. TNS-04002: CMCTL: error while starting the Connection Manager
The Connection Manager Administrator (CMADMIN) has started, but the Connection Manager Gateway (CMGW) has not.
Possible solution
The problem may lie in your cman.ora

address list can’t be parsed because the syntax is incorrect,
cman won’t start and you’ll get an error such as the one
shown here.
CMADMIN Is Running and Cannot Be Stopped
Symptom
The Connection Manager Administrator (CMADMIN) process is running by itself and won’t shut down when you issue a CMCTL STOP command.
Possible solution
There are two possible solutions for this problem. CMCTL STOP stops both CMADMIN and CMAN, but only if they are both running. If CMADMIN is running by itself, you should be able to stop it using the CMCTL STOP ADM command. If you are running on Windows NT, another solution is to go to the Services control panel, and stop the CMAdmin service.
