Hi,
I have installed the DB2 v8.1.2 over Redhat Linux 8.
I have started the db2 and opened the control center.
When i try to create a new database or do any operation at the control center i get an error
"SQL22212N A DB2 Administration server Communication error has been detected. Client system 127.0.0.1 or server system 127.0.0.1"

How can i overcome this error and use the control center and other tools successfully.
I am able to use the commands from the command line processor without any errors.

Any help is appreciated.

Did you start the Administration Server? To do so you need to log in as the administration server owner (default is dasusr1) and issue:
db2admin start

HTH

All I can give you is the Error message straight from the manual.

4. The DB2 Administration Server has not been cataloged correctly at the client system.
5. The communication subsystem at the client system or server system has not been configured correctly, or has not been started successfully.
6. A network error has caused the connection to go down.
7. An internal error in the DB2 Administration Server caused the connection to go down.
