Re: Large SVCDUMPS

[Longnecker, Dennis]

Thanks all.teach me for not keeping up with JCL parameters and knowing 
DSNTYPE=LARGE was actually a JCL option!

Putting
//  DSNTYPE=LARGE, 
In my allocation did the trick!

Subject: Large SVCDUMPS

Can someone point me to the right place to find the documentation on how to 
create large SVCDUMP datasets?   I need to create a large dump dataset so I can 
take a console dump of DB2.  I keep getting partial dumps.  I see in the 
messages the maximum size of a dataset is 65,535 tracks which for a 3390 is 
4369 cylinders.   In the z/OS MVS diagnosis: Tools and Service Aids manual they 
say "IBM Recommends using extended format sequential data sets as dump data 
sets for SVC dumps..and they can hold 128 gigabytes".But the manual 
doesn't give any clues on how to create them.

IBM APAR II06335 talks about the subject also:  " Note: With DFSMS120 and 
Dynamic Dump Allocation, multi-volume EFDS format datasets can be created for 
your SVCDUMP. "  but doesn't give any clues on how to create such a beast 
either.

I've tried created the SYS1.DUMP dataset on a MOD 9 with the contig option, but 
it stops at the 65,535 tracks.

Any pointers appreciated.

SMS. I don't know whether SDUMP supports EAV, but old fashioned
extended is good enough for mod 9.

  In z/OS 1.13, SDUMP specifies the DSNTYPE=LARGE text unit on
its SVC 99 parameters if the dump data set needs to be 
larger than 64K tracks. 

  Prior to z/OS 1.13, you can use Extended Format Sequential 
data sets for large dumps.  Such data sets must be SMS managed,
and you would make the request for Extended Format in your 
SMS ACS routines.

Re: Large SVCDUMPS

[Bobbie Justice]

I take it you've seen this already as well. 

from: II14016 


Another message to be aware of is  MSGIEA043I MAXSPACE REACHED.
  This indicates a PARTIAL dump. At minimum, set DB2 using system
  to a reasonable level, in MVS Commands see these commands:
 DISPLAY  : D D,OPTIONS
 CHNGDUMP : CD SET,SDUMP,TYPE=XMEME,MAXSPACE=8000M
  
  MAXSPACE=8000M minimum for DB2 z/OS V8 & later 

Note: See II06471 : DUMPSRV uses AUX storage for dumping, you
 may need to add an extra PAGE dataset when dumping DBM1.
   Note: Allocate a hi-capacity device like a 3390 mod9 for dumps.
  **use ACS routines for size ***
   Note: With DFSMS120 and Dynamic Dump Allocation, multi-volume
 EFDS format datasets can be created for your SVCDUMP.

Sir,

Try DSNTYPE=LARGE.

Re: Large SVCDUMPS

[Eatherly, John D]

Dennis,
  We set up a SMS pool and do dynamic dumps to that pool. This command is what 
controls the size allowed for the dump.

CHNGDUMP SET,SDUMP,MAXSPACE=6000M

You can display by doing D D,S

This is an example of the commands to start the SMS MGMT part.

DUMPDS NAME=SYS0.DUMP&SYSNAME..D&YYMMDD..S&SEQ  
DUMPDS ADD,SMS=(MGMT=MCDUMP,STOR=SCDUMP,DATA=DCDUMP)
DUMPDS ALLOC=ACTIVE

Hope it helps.

You specify whether a dataset is allocated in extended format in it's 
data class. I don't know off hand if SVCDUMP processing supports 
DSNTYPE=LARGE, but if so that would be another option.
