how can we determine the space if its a VSAM file

Hello,

Have the above replies answered your question?

I wanted to check how full the file is... Whats the current utilization of the file... When I just do the ListCat on the file I see the number of extents and primary space but not the actual size of the VSAM. It will be great if you could answer it...

Hello,

Please try this link http://ibmmainframes.com/viewtopic.php?t=21126&highlight=vsam+space

It looks like this question was answered yesterday.

If that does not get what you want, please let us know.

does that mean if high used RBA and high alloc RBA are equal, the file is 100% full and it cannot take anymore records in it.

No, it means that the current allocation of extents is used. If secondary extents have been allocated, or even additional DASD volumes, then the file will continue to grow.

Obviously if the file has reached 123 extents then unless another volume has been defined it will not accept more records.

the only starting point to analyze dasd utilization is the DCOLLECT output
augmented by the storage administrator samples from dfsort

for DCOLLECT look at the AMS refernece manual

for the storage administrator dfsort samples look at

How can we determine how many CYL, TRKS, BLKS used for a given VSAM on knowing the high used RBA and high alloc RBA

About six posts below this one is this one

Which if you had searched, you may have found yourself.

Thanks for the answers - But the above link gives me the percentage... Does the High used RBA and high alloc RBA gives me the physical space in CYLS. When I do Listcat I get the Extents and Tracks. Is that the physical space used by the file?

Thanks
