ORA-12505: TNS: listener could not resolve SID given in connection description.
When trying to connect to Oracle the following error is generated:
ORA-12224: TNS: listener could not resolve SID given in connection
The SID specified in the connection was not found in the listener’s tables.
This error will be returned if the database instance has not registered
with the listener.
This page represents one page of many pages of notes I made whilst working
with Oracle 7 through to 10i. I now no longer work with Oracle databases,
but hope that these notes will continue to be of benefit to others.
