SRB time is just the amount of CPU time accumulated by SRBs running in the address space and/or in dependent enclaves. The latter tidbit may be "TMI" since you're just getting your feet wet again. Ignore it for now. For most garden variety address spaces (batch, TSO etc.) the majority of the SRB time is caused by I/O completion processing. So the more I/O they do, the more SRB time you're going to see. For system and ISV product address spaces you may see quite a lot more SRB time because they're more likely to be using SRBs for internal functions. Then there's DB2 - the granddaddy of them all when it comes to SRB use. But ultimately this is another "tourist information" statistic because (a) you can't really do much to change it and (b) attaching the term "SRB" to plain old CPU time conveys a certain sense of deep internal systems voodoo for most people. Just think of it as part of the overall system overhead :-) CC ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
