Question

我刚收到此错误错误日志:org.apache.lucene.store.LockObtainFailedException:Lock获取超时:NativeFSLock@/var/database/schema/label/lucene/write.lock org.apache.lucene.store.Lock.获取(Lock.java:84)org.apache.lucene.index.IndexWriter.(IndexWriter.java:1098)org.neo4j.kernel.api.impl.index.IndexWriterFactories $ 1.create(IndexWriterFactories.java:44)org. neo4j.kernel.api.impl.index.LuceneLabelScanStore.init(LuceneLabelScanStore.java:301)org.neo4j.kernel.lifecycle.LifeSupport $ LifecycleInstance.init(LifeSupport.java:474)org.neo4j.kernel.lifecycle.LifeSupport. init(LifeSupport.java:72)org.neo4j.kernel.impl.nioneo.xa.NeoStoreXaDataSource.start(NeoStoreXaDataSource.java:337)org.neo4j.kernel.lifecycle.LifeSupport $ LifecycleInstance.start(LifeSupport.java:498) org.neo4j.kernel.lifecycle.LifeSupport.start(LifeSupport.java:115)org.neo4j.kernel.impl.transaction.XaDataSourceManager.start(XaDataSourceManager.java:165)org.neo4j.kernel.lifecycle.LifeSupport $ LifecycleInstanc e.start(LifeSupport.java:498)org.neo4j.kernel.lifecycle.LifeSupport.start(LifeSupport.java:115)org.neo4j.kernel.InternalAbstractGraphDatabase.run(InternalAbstractGraphDatabase.java:310)org.neo4j.kernel.

我已经使用java代码和使用库创建了我的数据库,所以请检查我是否直接关闭服务器以便当我收到此错误时如何恢复此数据库.

如何通过代码从文件中删除写锁定请分享您的视图.

Answer 1

你在同一个目录上运行Neo4j的第二个实例吗？

如果没有制作graphdb目录的备份副本,请删除并重/var/database/schema/label/lucene/write.lock试.
