                  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并索引文件时:

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

                  /usr/share/tomcat7/logs/solr.2013-12-11.log 文件中出现异常(大约等待 6 分钟后):

                  严重:org.apache.lucene.store.LockObtainFailedException:锁获取超时:NativeFSLock@/home/solr/solr3/biomina/solr/original/data/index/write.lock

                  (您可以在此消息的末尾看到它的详细输出).

                  我尝试修改锁的超时时间(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,只是使用 Solr 3.1.6 附带的 post.jar 来添加和索引.

                  关于需要更改哪些内容以消除此错误并成功将 XML 文件添加到 Solr 并对其进行索引有什么想法吗?

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

                  解决方案

                  以下修改解决了这个问题:

                  • 应用了 https://stackoverflow.com/a/3035916/236007 中描述的更改p>

                  • 切换到 Oracle Java 运行时(它是 IBM Java 运行时).

                  • ulimit -v unlimited放到/etc/init.d/tomcat7中.

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

                  • <代码>export JAVA_OPTS="$JAVA_OPTS -Xmx4000m -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/mnt/data/tomcat_dump"

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

                  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
                  

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

                  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.

                  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?
