HP XP7 Performance Advisor Database Listener service does not start after installation
or upgrade
After installing or upgrading HP XP7 Performance Advisor, the HP XP7 Performance Advisor
Database Listener service might not start automatically.
Cause
The HP XP7 Performance Advisor Database Listener service might not have started after an upgrade.
It can be due to an incorrect DNS name or a change in port number mentioned in the
listener.ora and tnsnames.ora files.
Resolution
Perform the steps listed to resolve the error:
Start the HP XP7 Performance Advisor Database Listener service manually by completing the
following steps:
1. Open the listener.ora and tnsnames.ora files available in the following location:
%PADB_HOME%\oradb\ADMIN\NETWORK.
2. If an incorrect DNS name is specified, replace it with the correct DNS name of the management
station. If the problem persists, replace the DNS name with the IP address of the management
station.
If a different port number is specified, change the port number to 1521, as HP XP7 Performance
Advisor uses port 1521 for the HP XP7 Performance Advisor Database Listener service.
3. Restart the HP XP7 Performance Advisor Database Listener service.
Go to Start ⇒ Run and type services.msc. In the Services dialog box, verify that the HP XP7
Performance Advisor Database Listener service has started.

data. These information metrics is not updated until the configuration collection is reissued in HP
XP7 Performance Advisor v5.4, v5.5, or v5.5.1.
