Hey April, > Need some advice on global_names. > Cloned a database, upgraded the 10.2.0.4 clone to 11.2.0.1. > Cannot drop any of existing database links - > ERROR at line 1: > ORA-02024: database link not found On your cloned DB with the issue, does the following query have the same values for each column reported (assuming non-RAC)? SELECT SYS_CONTEXT('USERENV','INSTANCE_NAME'), SYS_CONTEXT('USERENV','DB_NAME') FROM dual; Or, perhaps more correctly, how does the output from the above compare to the original DB?
