Application compatibility on DB2 for z/OS
In DB2 for z/OS® Version 11 and later versions, you can specify whether you want applications to run by using the features and behavior of the current DB2 for z/OS version or of a previous DB2 for z/OS version. For CLI and .NET applications that connect to DB2 for z/OS Version 11 or later data servers, you can control the application compatibility behavior in several ways.
