应用服务器- Glassfish启动失败

Question

我已经设置了一个glassfish服务器来学习它。在根据快速入门指南进行设置和配置之后，我能够毫无问题地运行服务器和domain1。一段时间后，它开始记录以下行:

[#|2013-01-11T15:43:45.246+0800|WARNING|glassfish3.1.2|java.util.prefs|_ThreadID=105;_ThreadName=Thread-2;|Could not lock User prefs.  Unix error code 5.|#]
[#|2013-01-11T15:43:45.246+0800|WARNING|glassfish3.1.2|java.util.prefs|_ThreadID=105;_ThreadName=Thread-2;|Couldn't flush user prefs: java.util.prefs.BackingStoreException: Couldn't get file lock.|#]

我在谷歌上搜索了一下，找到了这个链接，并应用了那里推荐的选项。重新启动glassfish后，尽管服务器日志显示它已启动，但我在命令行中看到如下内容:

./asadmin start-domain domain1
Waiting for domain1 to start .............Error starting domain domain1.
The server exited prematurely with exit code 1.
Before it died, it produced the following output:

我试图找到一个解决方案，删除域目录中的缓存文件夹或更改访问权限，但问题不断发生，我无法启动我的域。

有什么办法解决这个问题吗?

Answer 1

在安装Glassfish后，我有相同的IO错误，并发现以下内容:

Glassfish 3.1.2使用felix库来处理OSGI内容，而这个版本想要使用核心Java方法Java .nio.channels. filecchannel . trylock()来锁定文件。当要锁定的文件位于某些类型的NAS上的文件系统上时，这似乎不起作用，并且在长时间超时后会导致IO错误。确保将Glassfish的关键部分或全部安装在本地磁盘上，这个错误就会消失。

这个错误很容易在运行以下Java类时重现:

import java.io.File;
import java.io.FileOutputStream;
import java.nio.channels.FileChannel;
public class TryLock {
/**
 * @param args
 */
public static void main(String[] args) {
    // name of a file is the only parameter
    File lockFile = new File(args[0]);
    FileChannel fc = null;
    FileOutputStream fos = null;
    try {
        fos = new FileOutputStream(lockFile);
        fc = fos.getChannel();
        // This is the code that fails on some NAS (low-level operation?):
        fc.tryLock();
    } catch( Throwable th) {
        th.printStackTrace();
    }
    System.out.println("Success");
}
}
