We're looking at multiple structures to accommodate the heavy hitters. In our shop, DB/2, the occasional (all right, frequent) CICS looper, and the fact that Audit wants us to log all access attempts to production datasets including successful attempts has caused us in the past to lose SMF data. We may adjust up or down based on our experiences. Already I've dropped the system specific structures I mentioned in an earlier post in favor of SYSPLEX versions. I take your point though and it may be overkill but I may have to prove it to our Capacity folks. The information contained in this message may be CONFIDENTIAL and is for the intended addressee only.
