HP XP P9000 Performance Advisor v5.5 Software Troubleshooting and FAQs Guide (T1789-96344, February 2013)

Perform the steps listed to resolve the error:
Start the HP XP P9000 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 XP P9000
Performance Advisor uses port 1521 for the HP XP P9000 Performance Advisor Database
Listener service.
3. Restart the HP XP P9000 Performance Advisor Database Listener service.
Go to Start ⇒ Run and type services.msc. In the Services dialog box, verify that the HP XP
P9000 Performance Advisor Database Listener service has started.

displayed in Pool Tier table in the Pool screen
Cause

related data. These information metrics is not updated until the configuration collection is reissued
in HP XP P9000 Performance Advisor v5.4 or v5.5.
Resolution
After upgrading to HP XP P9000 Performance Advisor v5.4 or v5.5, reissue the configuration
collection for doremon arrays.
Connection not established with real-time server on the host agent
If you are not able to connect to the real-time server on a host agent, one of the following error
messages are displayed:
• Performance Advisor could not recognize the Real Time Server on the host agent <host agent
name>. This could be due to the Real Time Server not running on the selected host agent or
the host agent name is not found.
• Error occurred while connecting to Real Time Server. This could be due to the Real Time Server
not running on the host agent, or the same host agent is already being used for real time
collection by another instance of Performance Advisor.
Cause
It may be due to the following reasons:
• Real-time service is not running on the selected host agent.
• HP XP P9000 Performance Advisor host agent is not responding to your requests, as the
specified host name does not exist.
• Check if another user accessing the same management station has triggered another real-time
performance data collection. If you try to connect to a host agent that is already collecting the
real-time data initiated through another instance of HP XP P9000 Performance Advisor, the
existing connection is discontinued and the above-mentioned error message is displayed.
