Hello,

Have the above replies answered your question?

The space utilised and the space remaining on the DASD ?


Do you want to know how full a file is or how full a dasd device is? They are completely different questions.

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...

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
http://www-304.ibm.com/jct01004c/systems/support/storage/software/sort/mvs/srtmpkg.html

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
