What File Manager considers a shared file

For most of the commands discussed in this section, record integrity checking is only active when File Manager considers itself to be operating on a file in a shared environment.

A shared environment exists when File Manager is operating on:

A CICS® VSAM file (when you are using the FM/CICS feature), or
A KSDS VSAM file that is defined with SHAREOPTIONS 3 or 4, or
A non-KSDS VSAM file that could not be allocated to the region with a DISP of OLD (meaning that exclusive access to the file is not currently available) and the VSAM file is defined with SHAREOPTIONS 3 or 4.
