SET FILE/GLOB=DEFAULT -> several BugCheck/Crash

[Ruslan R. Laishev]

Hi there!

Is there someone who have tried to use a cool VMS feature as "V8.3 Global Buffering" ?


I tried ... got crashes. :-(

[Duncan Morris]

Ruslan,

what sort of "crash" did you experience? Process or system?

It works for me (see the attachment).

System's crash...

Your files about 140 blocks, my files -> 700 MBs - 3+ GBs.

[Duncan Morris]

Ruslan,

what was the crash?

If you have the CLUE$*.LIS from sys$errorlog, then please post it as ana attachment - I am sure that Volker/Hein would be keen to see it.

[Ruslan R. Laishev]

Attached.

I'm working with an RMS Engineer on a global buffers related crash.
That case is on I64 8.3-h1 and _might_ be specific to RELATIVE files.

Ruslan, I can not download your attachement (Duncan's TXT file works fine). Can you Email it to me, or stick it on EISNER and let us know where?

I'm sure that attachment would give the right details, but in the mean time, what about platform and exact version / patches?

What exact command is used .. on what file (size, typ, bucketsize): how many gloabl buffers were picked and how big did the section become. Less than 32K buffers?

When does it crash? On the SET FILE .. I doubt it.
On first usage? Under heavy concurrent usage? Read-only or active updates?
Specific program, or will for example a CONVER/SHARE/FDL=nl: file nl: crash it?

Maybe the system ran out of LOCK resources (pool) at a 'bad time'?

Finally, if this is for a production environment... The old interface allow up to 32K global buffers.. Typically that is plenty. Do you have 'evidence' it is not?

hth,
Hein.

Hein>> What exact command is used ..

The exact command was probably: "SET FILE/GLOB=DEFAULT".

That is only meaningfull to others when we know how the SYSGEN params GB_CACHEALLMAX and GB_DEFPERCENT were set... on top of the file characteristics.

Ruslan,

consider to just rename the CLUE*.LIS file as .TXT and attach it directly, without ZIPping it first...

Volker.

Hello, Hein!

Thanks. I just sent a mail to your gmail box.

Gentelemn,
I got my .zip back w/o problems.


Sysgen:
GB_CACHEALLMAX 50000 50000 100 -1 Blocks D
