Hi,
we use his 2000 to send data to our os/390 cics COBOL transaction.
We need to send more than 32k of content.
In the docs it's written that there's no limit on size of the message
but COMTI chunks the data in 32k frame.

Is there a way to change this behavior and sending the data
alltogether?

If not, what is the best way to recreate the area in the receiving host
transaction?

THanks

Carlo,

Back when I did mainframe CICS the commarea was limited to 32K. But that was
10+ years ago in CICS v1.x/2.x and early 3.x releases. What is the limit now?

Possible other ways of doing it would be to write the data to a mainframe DB/2
table, VSAM file etc. then kick off a CICS transaction pointing to the key for
the data.

You can override the default buffer size unfortunately not to a value
larger than you are already have. For any particular piece of data that
you are receiving which is larger than 32k you can redefine it with a table
something like 01 BIG-DATA OCCURS n TIMES PIC X(32763). and then bump
the table index after each receive.

Hi,
the limit of 32K it's only with CICS LINK using LU6.2 because CSMI is
used (not my case).

This 32k Chunks behavior is also for HIS2004?

Anyway, on the host side we already did something similar to handle the
incoming message in chunks.

Is there a way to know the total message size so we can allocate the
appropriate area?

HIS2004 Transaction Integrator limits the amount of data it will send at
one time to 32K regardless of whether the "Link" programming model is being
used or not.

If you look at the COBOL generated by the TIDesigner it will contain
comments that lists the size of the input and out areas.

Carlo - I'm afraid I don't know. Probably best if you open a case with MS PSS
and have them work it with you.
