I tried to import the login data from TOAD (which works perfectly) I keep getting the *** ERROR: ORA-12537: TNS:connection closed error. Even if I try to register source manually. We have 11.2.0.2 database on Linux server, with ASM.RMAN uses control file.Any idea?Best regards Create an account to join the discussion.
