Can I share the same VSAM control file across products?

Question & Answer


Question

What are the reasons for sharing the same VSAM control file across such products as DB2® Automation Tool, DB2 Log Analysis, DB2 Object Restore, DB2 Table Editor, and DB2 Query Monitor?

Answer

You can share the same VSAM control file among multiple subsystems. For example, one VSAM control file can be shared by all products, or you can have one control file for each product.

With one VSAM control file for all products, you only need to update the profile once with each DB2 subsystem. With one VSAM file for each product, you must update each VSAM control file with the profile information for each subsystem.

The only reasons for having multiple VSAM control files is either if you have multiple subsystems on different LPARS without shared DASD, or if you want to support multiple versions of the products in the same subsystem.
