Remove files and directories in /var/man
Description
Before z/OS V2R2, the /var/man directory was used by the man command. Starting with z/OS V2R2, the man command does not use this directory. Instead, it uses the /tmp directory on a per-user basis.

Steps to take
Follow
these steps:
- Remove the /var/man directory and all subdirectories and files on your z/OS V2R2 system. These files are no longer used for the z/OS V2R2 man command.
- The z/OS V2R2 man command uses the temporary directory for caching man pages. Each user has their own man page cache in the temporary directory. This change might increase the size of the temporary directory, depending on how much man command usage there is on your system. Monitor space usage for the temporary directory to ensure that there is adequate space for users to issue the man command. The temporary directory can be the directory referred to by the TMPDIR environment variable, or /tmp if TMPDIR is not defined.
