I get the error ORA-12560: TNS:protocol adapter error
on trying to execute server manager at the command prompt using the SVRMGRL command.
I set trace on in the sqlnet file and find that server manager tries to use BEQ as the protocol while it should be using TCP. All my files sqlnet.ora, listener.ora and tnsnames.ora refer to TCP as the protocol adapter. I am unable to find how server manager is picking BEQ. Please help.
