This is another SYSTEM, it is IBM P 550 with 6 Processors and with Memory 96GB / 32GB Paging Space. 1000 users connecting concurrently to the Oracle Database

This is one of the best topics and most useful one as many companies buy AIX machines solely for Oracle Database.

The machine is still running slow. How can one trace and fine tune ?

Code:

 Disk    Busy%     KBPS     TPS KB-Read KB-Writ  Steals     3458  % Comp     90.0
  hdisk1   98.5     1.6K  333.5     1.2K  446.0   PgspIn      307  % Noncomp   9.9
  hdisk2   88.5    10.8K  757.5     3.1K    7.7K  PgspOut     111  % Client    9.9

  oracle      3313978   5.9  34.9 oraprod         ServerV2       0
   
   
   
   
   
  Paging space is 35 .5 % 
   
  Hdisk 1 (which is internal server hard disk  not storage )is used with 98 %
   
  Hdisk2 is storage disk (which had DB )
