What Z Data Tools considers a shared file

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

A shared environment exists when Z Data Tools is operating on:
  • A CICSĀ® VSAM file (when you are using the ZDT/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.
