Hi,

I have a VSAM file having the following definition:

DEFINE CLUSTER(NAME' DSNS '-
REUSE -
VOLUMES(' OVOLSER '))-
DATA(-
RECORDSIZE(9237 18327)-
KEYS(22 0)-
CISZ(30720)-
CYL(20 30))-
INDEX(-
CISZ(512))


This is allowing me to load a maximum of 1118400 records into it. When i try to load data of more than this, it gives me an overflow error as follows:

IDC3351I ** VSAM I/O RETURN CODE IS 28 - RPLFDBWD = X'2908001C'

Please suggest, what parameters need to be adjusted to load data of more than 2200000 records. I have tried with various options but in vain.

An error was encountered during virtual storage access method (VSAM) open, close, or action request processing, as indicated in the text of the message.
The return code, as follows:
For a Logical I/O Error
28
Data set cannot be extended because VSAM cannot allocate additional direct-access storage space. Either there is not enough space left to make the secondary allocation request, you attempted to increase the size of a data set while processing with SHROPT=4 and DISP=SHR, or the index CI is not large enough to hold the entire CA. This error could also be due to a data set trying to extend beyond 4GB on a system that does not support extended addressability.

Thanks a lot.

But I guess, this is already available from the quick view (QW). I am aware. Can i have a solution to this?

Is there is enough space left to make the secondary allocation request?

Did you attempt to increase the size of a data set while processing with SHROPT=4 and DISP=SHR?

Is the index CI is large enough to hold the entire CA?

Are you trying to extend beyond 4GB on a system that does not support extended addressability?
