solr - WSO2 Enterprise Integrator - Solr 索引已损坏

问题描述

CorruptIndexException: file mismatch我有一个在 CentOS Linux 7 上运行的 WSO2 EI 6.1.1 实例，每次我部署任何类型的工件时，它都会出乎意料地在日志上吐出一个错误。WSO2 实例工作得很好，部署也完成了，但是索引出了点问题。服务器几天前内存不足，所以这可能是相关的。

这是整个例外：

我试图搜索如何在 WSO EI 上重置/重新索引，但所有结果都是针对 APIM 或 Analytics，并且文件不匹配。我也尝试过挖掘文件​​，但我对 WSO2 的内部工作了解不多。

解决方案

似乎注册表索引已损坏或未正确发生。您能否按照以下步骤重新索引注册表，

  1. 打开 registry.xml 文件，该文件位于<PRODUCT_HOME>/conf/.
  2. 改变lastAccessTimeLocation如下。前任：/_system/local/repository/components/org.wso2.carbon.registry/indexing/lastaccesstime_1
  3. 停止服务器，备份并删除 <PRODUCT_HOME>/solr目录。
  4. 重新启动服务器并等待几分钟以重新建立索引
