Problem: Cannot start a second co-existing Sybase Control Center in a deployment environment.
Explanation: When multiple versions of Sybase Control Center co-exist on a single machine, if the older version is already using the default port number, the new version of Sybase Control Center uses another port number, such as 8285. If the configuration files have not been updated, this may cause port conflicts.
Solution: Check the port numbers, and check the configuration files to make sure the configuration is correct. See the topic Port Number Reference. If the configuration is correct, you may need to start the second version of Sybase Control Center manually.
