SOME Errors in Oracle and their solutions June 10, 2010
SQL> ORA 12545 Connect failed because target host or object does not exist
Cause: The address specified is not valid, or the program being connected to does not exist.
Action: Ensure the ADDRESS parameters have been entered correctly; the most likely incorrect parameter is the node name. Ensure that the executable for the server exists (perhaps “oracle” is missing.) If the protocol is TCP/IP, edit the TNSNAMES.ORA file to change the host name to a numeric IP address and try again.
SQL> ORA-12541: TNS no listener
Cause: Listener for the source repository has not been started.
Action: Start the Listener on the machine where the source repository resides.

ORA-01665: controlfile is not a standby controlfile
Then ‘copy’ standby control file to other host and be sure its being used.
1) use an unusual name when you create it
2) verify it is transferred successfully
3) verify it is going in the right location by examining spfilE
4. verify that you are using the control file that you think you created in the alter database command. use the TO ‘c:\somwhere\stdby.ctl’ option of the command.
