jps 进程信息不可用 - jconsole 和 jvisualvm 不工作

发布于 2024-10-21 17:48:02 字数 568 浏览 5 评论 0原文

Windows 更新后,我的 jps、jconsole 和 jvisualvm 不再工作。

Jps 为我提供了进程 ID,但它告诉我进程信息不可用

而且我无法像以前那样使用 jvisualvm 连接到这些进程。

我正在运行 1.6.0_22 jre。

我过去已经遇到过这个问题,尝试 这个技巧,它奏效了。但这一次,运气不好,也无济于事。

编辑: 我找到了一个解决方案:在我的临时文件夹中,我确实销毁了 hsperfdata_ 文件夹。显然我的用户名大小写有问题。该文件夹名为 hsperfdata_myname。在通过调用 jps 销毁并重新创建后,它被称为 hasperfdata_MYNAME。

很奇怪。

After a windows update, my jps, jconsole et jvisualvm are not working anymore.

Jps gives me the process ids, but it tells me process information unavailable

And I'm unable to connect to those processes with jvisualvm as I used to.

I'm running the 1.6.0_22 jre.

I already had the problem in the past, tries this trick, and it worked. But this time, bad luck, it does not help.

Edit :
I found a solution : in my temp folder, I did destroy the hsperfdata_<username> folder. Apparently there was an issue with the case of my username. The folder was called hsperfdata_myname. After having been destroyed and re-created by a call to jps, it was called hasperfdata_MYNAME.

Very strange.

在我的临时文件夹中,我确实销毁了 hsperfdata_ 文件夹。显然我的用户名大小写有问题。该文件夹名为 hsperfdata_myname。在通过调用 jps 销毁并重新创建后,它被称为 hasperfdata_MYNAME。

在 UNIX 上,确保您以启动它的用户身份运行。

On unix, make sure you are running as the user that started it.

我们这里也遇到同样的问题。

tmp 文件夹技巧对我们来说也不起作用。

到目前为止,我们已经找到了几种使事情再次正常工作的方法:

  • 系统还原
  • 重命名“C:\Documents and Settings\myusername\Local Settings”下的临时文件夹并创建一个新的临时文件夹(我不确定这是一个安全的事情,对于 Windows...)
  • 开始手动从临时文件夹中删除内容
  • 可能是最安全的:运行 ccleaner,这将清理临时文件夹

we're having the same problem here.

The tmp folder trick didn't work for us, as well.

So far, we've found a few ways to make things work again:

  • a system restore
  • rename the temp folder under "C:\Documents and Settings\myusername\Local Settings" and create a new temp folder (I'm not sure that this is a safe thing to do, regarding to windows...)
  • start removing stuff from temp folder manually
  • probably the safest: run ccleaner, this will clean up the temp folder

我编写了一个脚本来应用解决方法,我从一些监视脚本中调用该解决方法,直到问题得到解决。

#!/bin/bash

# Purpose: create /tmp/hsperfdata directories that jps and jstat can work with

# for every /tmp/hsperfdata_[name] directory that exists
for fileHSP in `ls -d /tmp/hsperfdata_*`; do
        #echo "entry ${fileHSP}" # DEBUG
        # if our search returns entries that are not directories, skip them
        if [ ! -d ${fileHSP} ]; then
                continue
        fi

        #fi
    for filePID in `ls ${fileHSP}/ 2>> ${fileLOG} | grep "[[:digit:]]\{1,\}"`; do
            #echo "pid name: ${filePID}" # DEBUG
            # if the directory was empty, move on to the next fileENTRY
            if [ "${filePID}" == "" ]; then
                    #echo "the contents of the variable filePID appear to be empty \"${filePID}\"" # DEBUG
                    # remove the fileHSP if empty; this will clean up user hsperfdata dirs
                    rmdir ${fileHSP} 2>> ${fileLOG}
                    continue
            # if a symlink already exists, move on to the next fileENTRY
            elif [ -h /tmp/hsperfdata_${filePID} ]; then
                    #echo "symlink already exists for /tmp/hsperfdata_${filePID}" # DEBUG
                    continue
            fi
            #echo "name: ${filePID}"
            # if a process exists for filePID, create a symlink to the source file
            ps -eo pid | awk '{print $1}' | grep -q "^${filePID}$"
            RETVAL=$?
            # if a process exists with pid of filePID and a symlink doesn't exists, create symlink
            if [ $RETVAL -eq 0 -a ! -e /tmp/hsperfdata_${filePID} ]; then
                    ln -s ${fileHSP}/${filePID} /tmp/hsperfdata_$filePID
                    #echo ls -l /tmp/hs perfdata_${filePID} # DEBUG
            fi
    done
done

# remove broken symlinks
#find -L /tmp/hsperfdata_* -type l # DEBUG
find -L /tmp/hsperfdata_* -type l -delete

I wrote a script to apply the work-around, which I call from some of my monitoring scripts, until this is fixed.
