Charles, Just out of curiosity, are you trying to judge your own software's use of common storage or are you trying to assess if a vendor's use of common storage is too high?
Both are, of course, very worthwhile tasks. If it is your own software, then the sort of non-optimal use of common storage that I would advise that you investigate replacing would include : (o) Request blocks and queues held in common storage (o) Buffers for transient data (o) Memory bridges between two allied address spaces I am not saying that all usage of the above is invalid, however sometimes when code is originally authored it can be easier for the developer to use common storage rather than invest development time and resources into different techniques.

Main users VTAM, SMSVSAM, BMC CICS monitor Too much? Anything that would cause us to change ECSA size, which would be from 10M up towards 100M depending on LPAR. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ================================ Rocket Software, Inc. and subsidiaries ■ 77 Fourth Avenue, Waltham, MA 02451 ■ +1 800.966.3270 ■ +1 781.577.4321 Unsubscribe From Commercial Email – [email protected] Manage Your Subscription Preferences - http://info.rocketsoftware.com/GlobalSubscriptionManagementEmailFooter_SubscriptionCenter.html Privacy Policy - http://www.rocketsoftware.com/company/legal/privacy-policy ================================ ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
