Hi,
My Cobol program is writing into an ESDS vsam file. While creating the vsam file i used cyl(800,50) and dataclas(extend). Now because of huge volume of data, the cylinders given are not enough and it gave me the below message but the process didn't stop. Can I assume my dataclas(extend) saved me by auto allocating space?

I cant see how many records are written in vsam as the spool is too big it was archived.

Code:

You have some addon product,
the VAM.... messages are not from <IBM>

usually in this cases before investigating <IBM> behavior it would be better to investigate the addd on messages and behavior !

I think VAM is the old Sterling product that did similar things to SMS, not sure whose product it is now. It looks like it's doing some sort of 'best fit' processing, which is probably best done using the Dataclas Space Constraint Removal features instead.

You need to give more detail on your Dataclas. Does it have just Extended Format or Extended Addressability as well? Does it have Space Constraint Removal enabled, and does it have the Dynamic Volume Count value set to allow it to dynamically extend to more volumes?
