Subject: VSAM Space Allocation
Posted: Sat Apr 22, 2017 12:42 am (GMT 5.5)
Hi All,
I searched in the forum for my answers but I did not quite get it. Therefore, posting the questions.
1. In LISTCAT, I have the following scenarios
On what basis FREESPC could be different from HI-A-RBA - HI-U-RBA?
Should I take the RBA from Allocation section or the Volume section?
Ultimately I want one single method to compute the Free Space/Used Space for the VSAM Files.
I have given example for each of the above scenario
Scenario 1 (Data) & 3 (Index):
Scenario 2 (Data) & 3 (Index):

Hi All,

1. In LISTCAT, I have the following scenarios
| Code: |
1. HI-A-RBA = HI-U-RBA and FREESPC > 0 2. HI-A-RBA <> HI-U-RBA and FREESPC <> (HI-A-RBA - HI-U-RBA) 3. HI-A-RBA <> HI-U-RBA and FREESPC = (HI-A-RBA - HI-U-RBA)) |
On what basis FREESPC could be different from HI-A-RBA - HI-U-RBA?
Should I take the RBA from Allocation section or the Volume section?
Ultimately I want one single method to compute the Free Space/Used Space for the VSAM Files.
