WLM and skip clock

(or leaves them with reached velocity) until skip clock expires (so I was told). Is this skip clock concept described somewhere (manuals, papers ) ? Thank you in advance Max Scarpa Db2 sysprog -- For IBM-MAIN subscribe / signoff

Re: WLM and skip clock

Hi Mark, thank you for your reply I read it in redbook as well but as you said there's no 'direct' reference to skip clock concept, only a generic delay (skip) as it was considered useless to help that workload due to unattainable goals. Best regards Max Scarpa

SDSF slow after migration to z/OS 1.9

Greetings listers We're facin a problem we met after migration to z/OS 1.9. It's with SDSF. After migration we saw that SDSF is slow in response, expecially in displaying output classes. In some cases is VERY slow even if CPU is quite far from 100%. Did anyone encounter the same problem

Re: Real storage usage - a quick question

. Anyway is there any rule of thumb, having z/OS 1.7, for max central storage ? I mean, is there a suggested value to avoid RSM overhead before z/OS 1.8 (1 Gb ? 5, 10 or which value for central storage) ? Thank you in advance Max Scarpa Mark Zelden [EMAIL PROTECTED] Sent by: IBM Mainframe

Re: WLC, WLM and all the rest: how optimize them ? to Steve Samson - errata corrige

use potentially ALL CPU. Using a service class more agressive causes a raise in cpu usage, but only for reaching the higher goal. This is in contrast with some answers I received in the past ie that this job should use all CPU available. Any hint/tip ? Thank you a lot and best regards Max

WLC, WLM and all the rest: how optimize them ?

useful to reduce CPU demand with WLC. I know that there are good papers by Al Sherkow for example but they aren't downloadable from his site. Any help/hint/paper will be really appreciated. Thank you in advance Max Scarpa DB2 sysprog

DASDs Extents in DB2 world

to me that the previous are arguments like define VTOC in the 'middle' of a disk or using imbed/replicate of some years ago. Anyway, Is there anyone out there who had problems due to 1) and/or 2) reasons ? Thank you in advance Max Scarpa DB2 sysprog

Re: DASDs Extents in DB2 world

a procedure that reorganize tablespace when number of extent is high just to avoid (in the past) to hit extent limits. And I agree, we have index of VTOC now (...now, since many years). Anyway you confirm that VTOC is very slightly involved with extents. Thank you again and best regards Max Scarpa

Re: DASDs Extents in DB2 world

volumes (both dfp limitations and per component) = 7,257 extents –Striped VSAM data sets, up to 4080 extents per data component (16 stripes (volumes) max for VSAM*255 extents per stripe). With z/OS 1.7 the 255 extents maximum is removed for SMS managed components. Max Scarpa Ted MacNEIL

Storage group PAV

without any problem but here we are using PAV (so using alias). Is there any problem of defining so many volumes (not all really with a DASD) in a SG using PAV ? It seems to me to remember that PAV performance could degrade in this case but I'm not sure of this.- Thank you in advance Max Scarpa

Re: Storage group PAV

Hi Kees Actually I suspected it but some bosses were scared about having so many sms volumes with PAVs. Having many volumes defined tgo SMS even if not 'real' volumes gives me more flexibility in managing space shortages. Thank you very much MAx Scarpa Db2 sysprog

A quick question about velocity goals set high

shop in some CICS we lowered our goals without any delay in response time. Is still bad to put velocity goals higher than 80% ? In IMHO it is. Thank you in advance Max Scarpa -- For IBM-MAIN subscribe / signoff / archive access

Re: A quick question about velocity goals set high

but the difference between a goal of 90% and a goal of 70% was minimum for batch jobs and not so high for 1 or 2 CICS. Infact we had CICS velocity goals ranging from 30% to 50%. Thank you again and best regards Max Scarpa

Re: RSU value in a z900

Ted,MArk, thank you for your replies. The configuration I've in my mind is quite simple, no need (until now) to reconfigure memory. We are monoplex in 64-bit mode and - as I said - I read from this list that RSU should be 0. And now the problem is how to say it to our experts... Thank you again

Estimeed listers I'd like to have some information about RSU PARMLIB parameter. I saw in a z900 ( 2064-2C2, monoplex) installation a RSU = 32 when I read (am I wrong ?) that it'd be RSU = 0. I searched archives and I've found that RSU = 0 is recommended. Is still valid or are there any new

Re: RSU value in a z900

Hi Ted They're in 64-bit mode. What problems could they have with RSU specified and equal to 32 ? I heard something dealing with memory below 16M. So RSU = 0 is a mus from your reply... Thanks M. -- For IBM-MAIN subscribe /
