IMS/DB - Working with GSAM files.

Hi,

Shortly, I will be working on COBOL, DB2 & IMS/DB with GSAM access method. I request you people to tell me the critical details about this combination. What is peculiar about GSAM and what are the constraints? I never worked on IMS before.

Please let me know what is possilble / not possible while working on COBOL-DB2-IMS/DB (GSAM).

Thanks for your time.

Hi gowtham_1982,

Thanks for the inputs you've given. It is useful to me. I am told that a senior person will give a lecture on GSAM on IMS/DB after a week or two.

hy ranga,
gsam means general sequential access method,
means there is a possibility to use a sequentiel
dataset (input or output) like an ims-db.
this is useful for data integrity, means all data in
ims or db2 are in two phase commit state,
therefore the data integrity is always given.
If you work with sequentiel datasets as well,
data integrity is only given, when using your
sequentiel files as gsam files.
for a full discussion, wait for your lecture first,
then you will understand, it is easier as you
might think...
