Re: How expensive is AMODE switching?

It would need to purge the pipeline, wouldn't it? I would think that all the operand addresses for instructions in the pipeline would need to be recalculated. And I suspect it might affect instruction interlocks and out-of-order instruction execution, too.

Re: How expensive is AMODE switching?

... or there's some implication of AMODE switching that has not occurred to us. "It takes that long because it must _." I would think the cost might depend on how you measured it. (Doesn't it for every instruction nowadays!) I could certainly see SAMxx invalidating any branch prediction,

Re: How expensive is AMODE switching?

All I can say is WOW, also. There are only two reasons I can think of to have it cost that much. 1) It is a milli-code instruction, or 2) It purges the pipeline. If that time is for each instruction, then I tend to think it is milli-code. If the time is for a SAM64/SAM31 pair, then I think

I would think not much at all (but what I think and $4 will get you a coffee at the Poughkeepsie Starbucks). How hard long could it take to start using all of the bits of the registers for addressing rather than half of them? I would guess it might cause a refresh of the data cache, but that is

Thanks very much for this. Really I don´t guess about to read 2721 as hexa number but a normal number since it isn´t in x'' or 0x. 0d0b is clear that is hexa number but 2721 isn´t. Any way thanks again. CARLOS BODRA IBM Certified zSystem São Paulo - SP - BRAZIL Em 04/05/2016 15:16,

Re: ADR309E Message during Restore

You cannot do a full volume restore, so stated in the messages manual. What you can safely do is a selective data set restore. If you want to live dangerously, you could restore by track address. Dennis Roach, CISSP, PMP IAM Access Administration – Consumer – Senior Analyst 2929 Allen Parkway,

Re: ADR309E Message during Restore

If this was a logical dump, you could restore the individual datasets. Execute the restore job with PARM='TYPRUN=NORUN' to get a list of the individual datasets. If this is a physical dump, you have no choice. You *MUST* provide at least a 3390-9 to restore successfully. X'2721' is 10017

Re: ADR309E Message during Restore

It appears you are trying to restore a 3390 mod 9 to a 3390 mod 3. The 2721 you have listed below is hex for 10,017 which is the number of cylinders in a mod 9. In order to do a full volume restore your target volume will also need to be a 3390 mod 9 -Original Message- From: IBM
