如何解决使用Solr时“锁定获得超时”的问题？

本文介绍了如何解决使用Solr时“锁定获得超时”的问题？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我的Solr系统有两个内核（Solr版本3.6.1）。当我在我们的专用Solr服务器上调用以下命令行来添加然后索引文件时：

I have two cores for our Solr system (Solr version 3.6.1). When I invoke the following command line on our dedicated Solr server to add and then index a file:

java -Durl=solrprod:8080/solr/original/update -jar /home/solr/solr3/biomina/solr/post.jar /home/solr/tmp/2008/c2m-dump-01.noDEID_clean.xml

我在 /usr/share/tomcat7/logs/solr.2013-12-中收到异常11.log 文件（等待约6分钟后）：

I get an exception in /usr/share/tomcat7/logs/solr.2013-12-11.log file (after about 6 minutes of waiting):

SEVERE: org.apache.lucene.store.LockObtainFailedException: Lock obtain timed out: NativeFSLock@/home/solr/solr3/biomina/solr/original/data/index/write.lock

（你可以在这条消息的末尾看到它的详细输出）。

(You can see the detailed output of it at the end of this message).

我试图修改时间-out for locks（通过将 writeLockTimeout 设置为 300000 ），但这并没有解决问题。我没有使用任何自定义脚本，只需要Solr 3.1.6附带的 post.jar 来添加和索引。

I tried to modify the time-out for locks (by setting writeLockTimeout to 300000) , but this did not solve the problem. I'm not using any custom script, just the post.jar that comes with Solr 3.1.6, to add and index.

有关需要更改哪些内容以摆脱此错误并成功将XML文件添加到Solr并将其编入索引的任何想法？

Any ideas about what needs to be changed to get rid of this error and successfully add the XML file about to Solr and index it?

内容 /home/solr/solr3/biomina/solr/solr.xml ：

关联solrconfig.xml的一部分（针对名为的核心原创）：

Relevat part of solrconfig.xml (for the core named original):

<indexConfig> <!-- maxFieldLength specifies max number of *tokens* indexed per field. Default: 10000 --> <!-- <maxFieldLength>10000</maxFieldLength> --> <!-- Maximum time to wait for a write lock (ms) for an IndexWriter. Default: 1000 --> <writeLockTimeout>300000</writeLockTimeout>

relevat solrconfig.xml的一部分（针对名为的核心deidentified ）：

Relevat part of solrconfig.xml (for the core named deidentified):

<indexConfig> <!-- maxFieldLength specifies max number of *tokens* indexed per field. Default: 10000 --> <!-- <maxFieldLength>10000</maxFieldLength> --> <!-- Maximum time to wait for a write lock (ms) for an IndexWriter. Default: 1000 --> <writeLockTimeout>300000</writeLockTimeout>

推荐答案

以下修改解决了这个问题：

The following modifications solved the issue:

• 应用 stackoverflow/a/3035916/236007

切换到 Oracle Java 运行时（ IBM Java 运行时）。

Switched to Oracle Java runtime (it was IBM Java runtime).

将 ulimit -v unlimited 放入 /etc/init.d/tomcat7 。

修改 /usr/share/tomcat7/bin/setenv.sh 文件如下（给它大约4 GB内存）：

Modified the /usr/share/tomcat7/bin/setenv.sh file as the following (giving it about 4 GB memory):

export JAVA_OPTS =$ JAVA_OPTS -Xmx4000m -XX：+ HeapDumpOnOutOfMemoryError -XX：HeapDumpPath = / mnt / data / tomcat_dump
