Oracle XE TNSListerner Service Failure

Problem:

Oracle XE services in Windows refuses to start. An attempt to start  it from the ‘Services Windows’ in Windows 7 results in a dialog showing:

The OracleXETNSLIsterner service on Local Computer started and then stopped.
Some services stop automatically if they are not in use by other services or programs.

Prerequisites:

• Oracle 11g Express Edition, most probably it affects other oracle editions/versions.
• Windows 7  O/S, symptoms only noted on Windows.

Resolution steps:

1. Go to the command prompt and check the listener status

C:\>lsnrctl status

TNS-12560: TNS:protocol adapter error
TNS-00515: Connect failed because target host or object does not exist
32-bit Windows Error: 1001: Unknown error

TNS-12545, TNS-12560, and TNS-00515 errors occur after a migration to a new domain, oracle network files – tnsnames.ora and listener.ora – still references the old domain.

2. Change the domain part of the host to the new one

3. Restart the service :

C:\>lsnrctl start

or

From the ‘Services Windows’ in Windows 7

4. Check the listerner’s status again.

C:\>lsnrctl status
