I am not able to start my jira data center after doing some housekeeping activity

[Tariq Rana Sona]

I am not able to start my Jira data center after doing some housekeeping activity. While opening the Jira URL I am getting "Jira had trouble starting" page with below errors. I tried all the possible ways suggested on Atlassian page "Troubleshoot a Jira Data Center/Server startup failed error", but nothing worked.

"System plugins failed to start: We haven't been able to start all the required system plugins
We couldn't start the following plugins:
Jira Projects Plugin (com.atlassian.jira.jira-projects-plugin)
Atlassian Jira - Plugins - Project Config Plugin (com.atlassian.jira.jira-project-config-plugin)
Gadget Directory Plugin (com.atlassian.gadgets.directory)
Atlassian Jira - Plugins - Gadgets Plugin (com.atlassian.jira.gadgets)
Atlassian Jira - Plugins - Global Issue Navigator (com.atlassian.jira.jira-issue-nav-plugin)
Atlassian JIRA - Plugins - Quick Edit Plugin (com.atlassian.jira.jira-quick-edit-plugin)
Atlassian Jira - Plugins - REST Plugin (com.atlassian.jira.rest)"

For Jira, I have two Linux vms servers where one for application and another one for Jira database (Oracle). My Jira is hosted on nginx web server.

Has anyone any idea how to fix this issue.

Hi,

please frist check the logs for the "real" error. 

The UI message is generic.
check:

<JIRA_INSTALL>/logs/atlassian-jira.log

Here you will find hoefully the real error .
