当用户数量增加时，Lucene Indexing中的打开文件太多 [英] Too many open files in Lucene Indexing when number of users increase

问题描述

我一直在为我的网络应用程序使用Lucene Indexing和搜索技术。最初，我遇到了太多的打开文件问题，经过研究后我通过使用常见的IndexSearcher为单个用户修复了它。然后，当我用更多并发用户测试应用程序时，它再次开始带来打开文件太多问题。

I have been using Lucene Indexing and search technique for my web application. Initially I faced the "Too many Open files problem", after research I fixed it by using a common IndexSearcher for single user. Then, when I tested the application with a greater number of concurrent users, it again started to bring "Too many Open files problem".

我保留IndexSearcher对象特定用户的会话，它始终保持一些文件打开（他们当前正在使用）。即使有任何数量的用户，也可以帮助解决这个问题吗？

I am keeping the IndexSearcher Object in the session of particular user, which is always keeping a few files open(which they are currently using). Could any one please help to overcome this issue even if there is any number of users?

如果我在上述说明的任何地方都不清楚，请告诉我。

Let me know if I am not clear anywhere in the above explanation.

推荐答案

Lucene的FAQ有关于它的不错的条目。

Lucene's FAQ has a nice entry about it.

简而言之：

• 检查所有Lucene IndexReader，IndexWriter和IndexSearcher是否正确关闭


• 尝试使用复合文件，这限制了创建的文件数


• 增加操作系统上打开的文件句柄的限制

我遇到过与Lucene类似的问题在此之前，当您拥有大量并发用户时，可以轻松达到此限制。增加文件句柄限制工作完全正常。

I had similar problem with Lucene a while ago, and when you have a lot of concurrent users, this limit can easily be reached. Increasing the file handles limit worked perfectly fine.
