In two of our JES2 environments we use MOD-27s and in one other we use MOD-54s. 
 All three environments use TGSIZE=36.  I don't recall when it changed to 
TGSIZE=36, but it has been that way for years.  We have not seen any issues 
with either size volumes.  As Dave mentioned don't forget to set 
LARGEDS=ALLOWED.

$DSPOOLDEF                                                      
$HASP844 SPOOLDEF                                               
$HASP844 SPOOLDEF  BUFSIZE=3992,DSNAME=SYS1.CRS1.HASPACE,       
$HASP844           DSNMASK=,FENCE=(ACTIVE=NO,VOLUMES=1),        
$HASP844           GCRATE=NORMAL,LASTSVAL=(1999.164,06:34:51),

$HASP844           TGSIZE=36,TGSPACE=(MAX=3339040,              
$HASP844           DEFINED=1801635,ACTIVE=1637850,              
$HASP844           PERCENT=41.9087,FREE=951447,WARN=80),        
$HASP844           TRKCELL=3,VOLUME=OSSP

Dave, 

At your request! I should have provided it before...now where is that 2nd cup 
of coffee?

It would be helpful if you could post the output of a $DSPOOLDEF command.  We 
run with mod-54's with no issues.  Just make sure you code LARGEDS=ALLOWED

$SPOOLDEF                                               
SPOOLDEF  BUFSIZE=3992,DSNAME=SYS1.HASPACE,DSNMASK=,   
          FENCE=(ACTIVE=NO,VOLUMES=1),GCRATE=NORMAL,   
          LASTSVAL=(2007.294,12:08:34),LARGEDS=ALLOWED,
          SPOOLNUM=96,TGSIZE=30,TGSPACE=(MAX=2524640,  
          DEFINED=1202032,ACTIVE=1202032,

**CAUTION EXTERNAL EMAIL**

For years, we have run with 3390-3 spool volumes and a TGSIZE=24. I am not sure 
when or why the default became 30 and why it was not changed in my shop. 
Probably the wisdom of it is not broke, do not fix it. Okay, so much for 
history.

Shortly, there will be a push to go to all higher capacity spool volumes. At 
the moment, it looks like we are going to MOD-27s. What I am trying to 
determine is a better value for TGSIZE given the migration to the MOD-27s. 
TGSPACE has recently been tripled (still relatively small at 2.4 million). The 
rest of the numbers associated with SPOOLDEF are defaults.

Any suggestions would be appreciated. If it matters, DS8886 DASD.

Thanks in advance!

Bob
