Yes, the new SMS rules are only invoked at allocation. They will have no effect on an existing file. They will be invoked at delete/define. Are you going to use SMS compression on this file? In the past (last job) I reduced VSAM and sequential files by an average of 50%. This works fine as long as standard APIs are used. We had some clever consultants, long since departed, who wrote their own assembler I/O routines. It did not work so well for those files.
________________________________ Hi, I have a CICS VSAM file that is reaching it's 4gb limit. I want to create an SMS pool for it. Can I define all the constructs and activate the new rules while the region is up and using this file ? Will they take affect the next time the file is deleted/defined ? Please advise.
