标题: ommand "lsof" Shows High Number of Open Files [打印本页] 作者: 刘泽宇 时间: 昨天 13:47 标题: ommand "lsof" Shows High Number of Open Files 现象：
After configuring and starting FMW 12c Forms and Reports on RHEL7/OL7, open files count is too high when listing using lsof command.
Open file count decreases once services are stopped.
Same behavior is not seen in RHEL6/OL6
Below is the difference seen between RHEL7/OL7 and RHEL6/OL6.
RHEL7/OL7
$ lsof |wc -l
904392
RHEL6/OL6
$ lsof |wc -l
10721
原因：
default output of lsof command is different in RHEL6/OL6 and RHEL7/OL7.
The “lsof” command on RHEL7/EL7 show output including **TID** as default compared to RHEL6/OL6
This is explained in the Bug 24978109 - HIGH NUMBER OF OPEN FILES IN 12.2.1.1 ON RHEL/OEL 7
处理方法：
No Changes required in the environment as this is expected behaviour and “lsof” command on RHEL7/EL7 shows output including **TID** as default compared to RHEL6/OL6.
