The following article outlines a short checklist of questions to ask and steps to take before opening a Shutdown/Inoperable Systems ticket in Liferay Help Center. By taking a moment to go through this checklist before opening a Help Center request, you're ensuring the fastest possible resolution for the particular issue.
Resolution
For each ticket, please attach your portal-ext.properties file as well as the output of the patching-tool info command specific to the environment.
For shutdown/inoperable systems error tickets, in the event the system becomes shutdown or inoperable, please work through the following checklist and include the resulting information when you create a Help Center ticket:
- Check the application server logs, searching for error messages related to peripheral systems connection and verify they are up and running and reachable from the Liferay DXP servers.
- Because Liferay DXP works in cooperation with other systems, those too need to be checked such as, but not limited to:
- Database connections
- Search index servers (Elastic, Solr) connections,
- LDAP servers
- Web servers
- Lastly, check your infrastructure such as, but not limited to:
- Network settings,
- Physical servers,
- Memory allocation,
- Hard drives
- Firewall
If any of those systems or the infrastructure are malfunctioning, it is unlikely that Liferay DXP can operate normally, exhibiting different types of errors.
