[hibernate-issues] [Hibernate-JIRA] Closed: (HSEARCH-511) Clean up orphaned lock files on startup

[Sanne Grinovero (JIRA)]

     [ http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-511?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Sanne Grinovero closed HSEARCH-511.
-----------------------------------

    Resolution: Won't Fix

Removing the lock defeats the purpose, if you really want to remove the lock you can configure a different locking mechanism as explained on [LockFactory Configuration|http://docs.jboss.org/hibernate/stable/search/reference/en-US/html_single/#search-configuration-directory-lockfactories] in the reference.
Selecting *single* for example you would have a fair protection to prevent the MassIndexer to use the index concurrently to normal work, but in case of a restart the locks would be gone.
I hope this is a good solution for your case, if you need an explicit API please discuss it on the mailing list we would like to hear about it.

> I have had several occassions when the MassIndexer failed to complete for some reason and I had to restart Tomcat. MassIndexer creates lockfiles for the indexes it is updating. These lock files remain after a restart and block MassIndexer from running again. 
> I suggest that Hibernate Search during startup checks for the existence of lock files in the index directory and removes then if they are there. This prevents an administrator from having to go and do it manually which is a bummer in production.
