Working with File Manager 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 File Manager for CICS® feature, or
- The base File Manager 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.
