Hello,
Adaptive Server Enterprise/16.0 SP02 PL02/EBF 25318 SMP/P/RS6000/AIX 7.1/ase160sp02plx/2492/64-bit/FBO/Sun Nov 22 18:44:08 2015
sp_configure 'number of sort buffers'
go
Run Value = 5000
sp_configure 'procedure cache size'
go
Run value = 1200000
We have enough caches configured ( about 76GB ).
We have may large tables ( having more that 200mill rows ) and need to kee statistics up to date. Requested one of the DBA to increase 'number of sort buffers' to 20000.
Here is his response.
Given what we know about the relationship sort buffers have with procedure cache, clustered and non-clustered indexes, quadrupling sort buffers will likely create more performance problems not less.
Question:
1. Is there is any relationship between these two.
2. Has anybody seen any performance issue after increasing 'number of sort buffers'?
Thanks,
Sid.
