Hi,
below are two Limitations reg. VSAM
1. VSAM clusters can acquire up to 123 extents in one volume. Multivolume VSAM data sets can now have a maximum of 255 extents across volumes for each component, but no more than 123 extents per volume.
2. Standard VSAM files have a 4GB (4,294,967,295 Bytes) limit.

Now my doubt is when the VSAM file will not allow adding any records:
1. IF it reaches 1st limit.
2. IF it reaches 2nd limit.
3. Whichever of the above occurs first; whether it reaches 4GB space utilization or 255 extents utilization.
4. Any particular limit of the two.

Please clarify me.
