my hsql database of JIRA has been corrupted due to power-jerk, we have been trying to recover this Hsql database but we haven't found any proper solution yet.is there any way to recover this database?
Did you use HSQLDB for a production environment? Because this is absolutely not recommended: https://confluence.atlassian.com/display/JIRA/Connecting+JIRA+to+HSQLDB
If you have the XML Backup service enabled, it might have saved some of your data in JIRA_HOME/exports
