Hi Admins,

I have a Patrol for Monitoring my servers.

Patrol show me an alert on a Server Solaris 8, on the MEMWCache parameter
that is less than 20%. Patrol Help tell that follow:

MEMWCache Parameter

This parameter displays the percentage of logical blocks written in the
buffer cache. The write cache hit ratio indicates the effectiveness of
system buffering. If you run I/O intensive applications and you have a
large memory configuration, you may want to reconfigure your memory so
that the write cache hit ratio is around 80 percent.

How i can to reconfigure the memory to put this percent around 80%????

Or, how to do it for put this parameter on 80 percent?????

Regards

Pablo Salazar
