 Posted: Mon Jun 25, 2007 1:46 am Post subject: To get number or % of extents left of a VSAM file. |
 |
|
Could you please help me out from the problem.
I am using LISTC for getting the properties of the VSAM file in SYSOUT in JCL. It is giving all the information allocated to the that VSAM file like allocated extents, storage, primary and secondary storage etc.
But my problem is that I want to get the information on the number of extent left or % left and also storage left or % storage left for the particular VSAM file.
Thanks (in advance)

baansal,
If your shop has File-aid then from the main menu of file-aid
1. select
| Code: |
3 UTILITIES - File-AID/SPF extended utilities
|
2. on the next screen select
| Code: |
5 VSAM - Allocate, display,
|
3. on the next screen give the vsam cluster name and press ENTER
4. On the next screen press ENTER once again and on the right side you will see the percentage allocated/used
Hope this helps...
Cheers
Kolusu

Hi Kolusu,
I appreciated your answer, but as i have written, i need to show the required information in the sysout dataset of the JCL. I need to get the information through JCL.

baansal,
Search for the following fields in your Listcat output
| Code: |
High Used RBA = HI-U-RBA
High Allocated RBA = HI-A-RBA
|
The formula for calcuating the VSAM Percent free is
| Code: |
(High Allocated RBA - High Used RBA) \ High Allocated RBA. |
The formula for calcuating the VSAM Percent used is
| Code: |
High Used RBA \ High Allocated RBA.
|
Hope this helps...
Cheers
Kolusu
