|
|
Hi Board,
We are increasing space allocation for the Datasets in production due to huge volume of data is going to come.
We have got the requirements like below
If (CYL,(200,50),RLSE)(Old Allocation)
Add New Volume of 65+ --------> (CYL,(350,75),RLSE).
Anyone can tell on How this space have been calculated?
I mean how this 65+ have been utilized to get the (CYL,(350,75),RLSE). _________________ Best Regards,

Ramu_mohan21,
I am not sure what you mean by 65+ in here , but the total space allocated for a reqular sequential dataset is calculated as follows
Code: |
Total space allocated = primary space qty + (15 * secondary space qty)
|
So in your old allocation it would be a total of 950 cylinders (200+(15*50) = 950)
With new allocation it would be 1475 cylinders(350+(15*75) = 1475)
Check this link for a detailed explanation of calculating space based on LRECL and Volume of data

Hope this helps...

HI Mfjin,
I have got information from our onsite counter part is 65+ is related to more than 65000 records per day. Previously we use the get less than 65000 records. Hence the previous space was sufficient. Here I have got information from Kolusu's reply how to calculate space. It is relevent to me. Hence my doubt is clarified. _________________ Best Regards,
