WSO2 企业集成商 - Solr 索引损坏

Question

我在 CentOS Linux 7 上有一个 WSO2 EI 6.1.1 运行的实例，突然它开始在日志中每次都吐出一个 CorruptIndexException: file mismatch 错误我部署任何类型的工件。 WSO2 实例运行良好，部署也已完成，但索引编制出现问题。几天前服务器内存不足，所以这可能是相关的。

这是整个异常：

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 的，并且文件不匹配。我也尝试过挖掘文件，但我对 WSO2 的内部工作原理了解不多。

Answer 1

注册表索引似乎已损坏或未正确生成。您能否按照以下步骤重新索引注册表，

打开 registry.xml 文件，它位于 <PRODUCT_HOME>/conf/.
如下更改lastAccessTimeLocation。例如：/_system/local/repository/components/org.wso2.carbon.registry/indexing/lastaccesstime_1
停止服务器，备份并删除<PRODUCT_HOME>/solr目录。
重启服务器并等待几分钟重新索引
