I Need More Hardware!

Actually, this is one of the few times I can remember in my career when I can honestly say I have enough horsepower at my disposal.

Want to guess what I’m running right now?

> select count(*) from v$asm_disk where name like 'DATA_XXX%';

  COUNT(*)
----------
       504

> select sum(total_mb)/1024/1024 tb from v$asm_disk;

        TB
----------
 272.15918

> select count(*) from gv$instance;

  COUNT(*)
----------
         6

[oracle@somehost: ~]$ cat /proc/meminfo | grep MemTotal

This POV will probably generate a number of follow-up posts. One concept: there are always bottlenecks. When you remove the hardware bottlenecks, bottlenecks in your code quickly surface.
