>Where does HC get this info from? I'd say that "HC" does not get the info from anywhere. This is a VLF health check, so VLF gets the information from its own control structures. VLF knows when it cached something and when it trimmed it (i.e., chose to remove the item from its cache for space reason). Thus it knows the "age" of the item that is trimmed and can compare that to the AlertAge.
>This is useful information for adjusting the size of the VLF cache, >but why is this value not made available in VLF's SMF 41-3? Because no one has asked for that to be done (and we didn't think about it when considering implementing the health check). That certainly seems like a good thing to consider. Feel free to open an RFE to request it. For example, perhaps what you would want in the SMF record for each VLF class is: -- the class's AlertAge -- the class's current minimum age (when the minimum age is less than the AlertAge, the check flags this as an exception) Peter Relson z/OS Core Technology ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
