TSQ limitation & Queries

Postby Yong » Mon Sep 27, 2010 9:08 am

Hi,
I am preparing a paper about session management in mainframe using TSQ, Can someone let me know the TSQ limitation and the answers to below questions:
1)What's the maximum number of items/records can be stored in TSQ?
2)How long will TSQ exist in memory if not accessed, such as expiration time,will CICS automatically delete TSQ if it is not referenced and not manually deleted/purged by user?
3)The size limitation of each item/record, i think it is 32763 bytes, please correct me if it is wrong.
4)Is there any back up/recovery mechnisam can be used for TSQ?
5)How doesn Read/Write/Rewirte TSQ work? is it operating on Primary DASD dataset in memory?

Any guild/reference book will help, as detailed as possilble!

Thanks,
Yong

Hello and welcome to the forum,

It will probably help someone help you if you explain what "session management" means to your study. Usually, a "session" is when someone logs into tso, cics, or some other online service. These onlines are managed internally by their respective environments .

Suggest you read here:
http://publibz.boulder.ibm.com/cgi-bin/ ... 3c00/4.9.1
and follow the individual items here:
http://publibz.boulder.ibm.com/cgi-bin/ ... &rank=RANK

These links are to parts of the CICS Language Reference and Programming Guide documentation.
Hope this helps,
d.sch.
