jps出现– process information unavailable解决方法_html/css_WEB-ITnose
使用jps命令查看java进程，经常出现类似"3135 -- process information unavailable"，有两种情况，第一种：3135这个PID存在，原因为当前ID为其他用户启动，该用户没有查看权限。第二种：3135这个PID不存在。
jps命令process information unavailable
# jps631 Jps3135 -- process information unavailable24351 Bootstrap323 Bootstrap2978 -- process information unavailable
# jps631 Jps3135 -- processinformationunavailable24351 Bootstrap323 Bootstrap2978 -- processinformationunavailable
解决process information unavailable
/tmp中找到hsperfdata_前缀的目录，并找出PID对应的文件并且删除即可。
# rm /tmp/hsperfdata_ttlsa/3135# jps744 Jps24351 Bootstrap323 Bootstrap2978 -- process information unavailable
# rm /tmp/hsperfdata_ttlsa/3135# jps744 Jps24351 Bootstrap323 Bootstrap2978 -- processinformationunavailable
可以发现3135不存在了，接下来在删除2978
# rm /tmp/hsperfdata_ttlsa/2978# jps759 Jps24351 Bootstrap323 Bootstrap
# rm /tmp/hsperfdata_ttlsa/2978# jps759 Jps24351 Bootstrap323 Bootstrap
