ommand "lsof" Shows High Number of Open Files

刘泽宇

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.

Hence the number of open files count increases.
