Default nuevamente Performance


Hola
Estoy con algunas dudas, las mismas que finalmente se reproducen en
problemas de performance para mi servidor de base de datos.
Mi plataforma basicamente es la siguiente:
HP-UX 11.11, 4 CPU's y 12GB de memory.
Revisando literatura respecto a Performance and Tuning, modifique
algunos parametros de mi onconfig: CLEARS, LRU, BUFFERS, LOCK, LRU_MAX_DIRTY
y LRU_MIN_DIRTY, las mismas que se suponia me permitir ontener una mejor
performance.
Al reiniciar la instancia y ejecutar el onstat -p, mi %cached = 98%, por
tanto asumi que habia realizado las modificaciones correctas. Pero
lamentablemente, con el transcurrir de los dias y al ejecutar nuevamente
onstat -p, mi %cached = 93.86%.
Por que sucedio esto?
Como puedo llegar nuevamente al %cached optimo = 98%
Me pueden dar algunas pistas para poder obtener mejor performance y
orientarme por que factores pasa tener optimizado mi servidor de base de
datos.
Gracias por la ayuda.

saludos

Hello:
I am with some doubts, the same ones that finally they reproduce in
problems of performance for my database server. My platform basicamente is
the following one: HP-UX 11,11, 4 CPU's and 12GB of memory. Reviewing
Literature with respect to Performance and Tuning, modifies some parametros
of my onconfig: CLEARS, LRU, BUFFERS, LOCK, LRU_MAX_DIRTY and LRU_MIN_DIRTY,
same that suponia to allow itself me to ontener one better performance. When
reinitiating the instance and executing onstat - p, my %cached = 98%,
therefore asumi that habia made the correct modifications. But lamentably,
with passing of the days and when executing again
onstat -p , my %cached = 93.86%. So that sucedio this? As I can again arrive
at %cached optimal = 98% . Can give some tracks to be able to obtain better
performance and to orient to me so that factors happen to have optimized my
database server.

Thanks for the aid.
