Hi,

While defining a transaction in an online region, I can see the following code

Code:
APPLCTN PSB=PXXXX001,                             
      SCHDTYP=PARALLEL,PGMTYPE=TP
TRANSACT CODE=TXX001,                             
      MSGTYPE=(MULTSEG,RESPONSE,2),PROCLIM=(1,5),
      SEGSIZE=2048,SPA=(2048),                   
      PARLIM=1,                                   
      MODE=SNGL

Could you please tell , what each field stands for and I want to know how you will determine the SEGSIZE and SPA size ?

Thanks,
Paul

Edited to add the BBcode...Anuj D.

SPA - Scratch Pad Area is mainly used for conversional program.simply say, it is a temporary storage.Here you can store lot of message.
I think,Google is one of the best friend for programmer..why not try?


Thanks,

Hi,

I'm aware of the SPA area concept.But while defining a new transaction, I'm not sure about on what basis the SEGSIZE and SPA size is given.I searched in google but didn't get much info..

Thanks,
Paul

Hello Paul,

While Google is often your friend, there are a couple of places i'd suggest looking before going to the whole web. One is the "IBM manuals" which are linked at the top of each page - IMS documentation is available there:

http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/handheld/Connected/BOOKS/dfsapgg1/6.3.3?

http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/handheld/Connected/BOOKS/dfscr1g1/2.3.3.2?

A seond place to look is in the forum SEARCH. Many questions have previous discussion.

Most fast paced high transaction processing installations do not use the SPA. Make sure that your installation allows it. Also remember that SPA and non-SPA MPP programs do not "talk" to each other.
