it is 1 cylinder

it cant be 1 control interval

since some records may take more than 1 CI they are called as spanned records.

so  maximum record length could be 1 cyl.

Hi ,

Of all the answers provided. The answer provided by DRSCBALAJI is correct. It is Max of 1 cylinder.

The reason he gave is also correct, since there can be SPANNED RECORDS which can cover multiple CI's. But a spanned record can never cross a CA. And the maximum value for a CA is 1 Cylinder. So ultimately the maximum size of a VSAM record will be 1 Cylinder.

Thanks and Regards

What do you mean by record size? Are you asking about physical terms or logical? I can't say about current vsam but at one time the records were 512,1024,2048, and 4096. CIs which are the logical record could read multiple records and present them as a logical record from a read. So if you are asking about the largest physical record that vsam supports, I believe the answer is 4K but if you are interested in the CI which would look like 1 record to you, I believe the answer is 32k.
