How does tnsManager work?
- The client PC initiates a connection to HR_DB. Because the Oracle client has been configured to use LDAP instead of tnsnames, a request is sent to tnsManager.
- tnsManager responds with a connection string for HR_DB.
- The client PC disconnects from tnsManager and makes a direct connection to HR_DB - just as if it had used a tnsnames.
If, in the future, the DBA decides to move HR_DB to a new server called 'Server2', all that is required is an update to the central tnsnames.ora held on the tnsManager server.
