Working with Z Data Tools and shared files

This section describes how to work with VSAM files in a shared environment. This may be as a result of using:
  • The Z Data Tools for CICSĀ® feature, or
  • The base Z Data Tools product and accessing a VSAM SHAREOPTIONS 3 or SHAREOPTIONS 4 KSDS file, or another type of VSAM SHAREOPTIONS 3 or SHAREOPTIONS 4 file that could not be allocated exclusively to the user or region accessing it.
    Note: The use of VSAM SHAREOPTIONS 3 files for multiple users where the file may be updated is not recommended as VSAM offers no methods for data integrity for SHAREOPTION 3 files. For this reason, results with such files may be considered unpredictable.
