I misread the LISTCAT output to get my number, so my apologies. EXAMINE will definitely take longer than a LISTCAT -- EXAMINE is doing much more.
Why do you think you will have sudden growth in data sets? Unless data comes in from a third party, it is quite rare for there to be drastic jumps in the amount of data processed each day. The way to handle such a case is to have the VSAM data set big enough to hold a daily spurt, and then offload / delete / define / reload the data every night if it is required. Using LISTCAT (or EXAMINE) multiple times a day seems like a lot of wasted effort.
