Hello,
You need to provide much more detail about what you need to do and your concern(s).
What is "huge" to you?
Why do you believe you need to be concerned with leaf pages?
What does your dba suggest? |

Hi,
To me, huge is deleting 500,000,000 records on our on-line partition table space with 1,500,000,000 records.
About leaf page I checked and deleted 10,000,000 records in our test system after reorg and runstat utility, I found that the leaf pages are increase.
I am DBA and looking for the other DBAs suggestion.
Hope this helps,
Manshadi |
