hi there,

if i am not mistaken the max size of the commarea is 32k.

is there a minimum size? would it be 4k?

my question is: how offensive is it to CICS to use 32k commareas?

to make a long story short, what is more expensive? the opening of a db2 select cursor or using 32k commareas?

Hi jctgf,
Yes the max size of Commarea is 32K, but as far as min size is concerned I am sure this 4k restriction because I am able to successfully pass a COMMAREA of size 0 [EIBCALLEN = 0].
The size of commarea is resource intensive in terms of storage but it is definately less than the DB2 multiple time opening the cursor and fetching the data storing and passing through COMMAREA.
Nowadays, you can also choose channels where the 32k limitation is not imposed. Follow this link for more details
