The types of connectivity issues you may encounter include:
- web server connectivity problems.
- database connectivity problems.
Web server connectivity issues:
To troubleshoot web server connectivity problems:
- Use the ping utility to check connectivity to the management server at the IP layer.
- If the server is responding to ping, log onto the server as the ENA user with the requisite rights.
- Check that there is an httpd web server process running on the management server. For example, enter:
ps -ef | grep httpd
- If there is no httpd process running, use the starteye utility to start one.
- If there is already an httpd process running, check the web server log files (see the article on Checking System Log Files) to ascertain the cause of the problem. It may be necessary to kill the current processes, and restart them using starteye.
To troubleshoot web server connectivity problems if you are a Windows user:
- Use the Windows Task Manager to check that the httpd server is running:
- if it is not running, wait a short while because it should restart automatically. Otherwise, use starteye or start the ENA service to start one.
- if it is running, check the web server log files to determine the cause of the probloem. It may be necessary to restart Windows.
Database connectivity issues:
To troubleshoot database connectivity issues:
- Log into the management server as the ENA user with the requisite rights.
- Navigate to the Process Health page and check that the ENA processes are running.
- If any processes are not responding, check the appropriate log files, and then shut down and restart ENA.
