How to add Extended Addressability to VSAM datasets?
Do we need to make any change in the control card where we are specifying the define cluster statement

(The thing is that job is not able to handle more then 4 G.B. data so we need to provide Extended Addressability support, please let me know.......)

Easy, talk to the storage group. VSAM extended capabilities are controlled by them in the ACS routines.

Thank you so much, as I was searching for this for last two days in net for this.
Can you please tell me one thing more, Do we need to make any change in the control card where we are specifying the define cluster statement or not ?

Totally depends on the site setup. So the answer could be YES or NO.

I asked storage group to add this feature.
Now, they are going to add the SMS ACS rules to VSAM files icon_smile.gif ,
what we should asked them to do apart from this.
Do we need to specify extended addressability parameter in Data class ?

As I said, it all depends on how the storage people set up the ACS routines. You may have to use a specific DATACLAS and/or STORCLAS parameter in the IDCAMS statements, or you may not. You need to ask them how they have set it up, not me.

I once had a similar problem I believe, I got around this by choosing a dataclass which has an extended addressability as yes(look in ISMF)..I know the question is answered just wanted to share my view..

Hello

Once we have defined the extended VSAMS, what other places are affected? I mean, do I need to change the code also, somewhere, in order to enable its use?

I researched it a bit and could not find any specific manual which lists this out in detail. Does anyone has any reference?

Also, I could see that the we need to use XRBA instead of RBA in the macros like GET, POINT and so on.

Just looking for a proper guidance (manual) to enable extended addressability for VSAM.

Any suggestions would be helpful.

Thanks

WHAT code? COBOL code does not need any changes, but if you're using assembler then you need to change the code for XRBA (for example).
