[hibernate-issues] [Hibernate-JIRA] Issue Comment Edited: (HSEARCH-998) Unlock at startup using SimpleFSLockFactory

Unlock at startup using SimpleFSLockFactory ------------------------------------------- Key: HSEARCH-998 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-998 Project: Hibernate Search Issue Type: New Feature Components: massindexer Environment: Java 1.6, Hibernate Search 4.0.0.CR2 on Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - 64bits Reporter: David Polo Labels: hibernate I'm using SimpleFSLockFactory and I'm getting this exception after an unexpected shutdown of the application during indexation: org.apache.lucene.store.LockObtainFailedException: Lock obtain timed out The workaround consists in executing this code at startup in order to unlock the indexes: FullTextSession fullTextSession = Search.getFullTextSession(hbSession); MutableSearchFactory searchFactory = (MutableSearchFactory) fullTextSession .getSearchFactory(); IndexReader indexReader = fullTextSession.getSearchFactory() .getIndexReaderAccessor().open(""); Map<Class<?>, EntityIndexBinder> indexBindingsForEntity = searchFactory .getIndexBindingForEntity(); for (EntityIndexBinder eib : indexBindingsForEntity.values()) { IndexManager[] indexManagers = eib.getIndexManagers(); DirectoryBasedIndexManager indexManager = (DirectoryBasedIndexManager) indexManagers[0]; Directory indexDirectory = indexManager.getDirectoryProvider() .getDirectory(); if (IndexWriter.isLocked(indexDirectory)) { IndexWriter.unlock(indexDirectory); } } I have a single application that executes this code at startup so I think it's safe to unlock the Directory at this time. I'm doing this because I'm using SimpleFSLockFactory and it leaves write.lock files. I need to unlock at startup because I think using NativeFSLockFactory is not an option for me (I'm using NFS). It will be a good thing if Hibernate Search have an "unlock at startup" option. It could be used only in cases like this (not all cases!). In Solr there is an option: <unlockOnStartup>true</unlockOnStartup>
