Buffer Hit Ratio

Oracle

The buffer cache hit ratio calculates how

often a requested block has been found

in the buffer cache, without requiring

disk access. If the ratio is less then 90

percent investigate further. You may

need to increase cache size by

increasing db_block_buffer(8i) or

db_cache_size(9i).

CPU Usage

Percentage (%)

Sybase

Percentage of the Sybase CPU being

used. For example, if this monitoring

appears pegged at 100 percent, this

means one or more Sybase databases

on the host are using 100 percent of the

Sybase CPU, not the host CPU. The host

CPU could be pegged at 60 percent,

while the Sybase CPU is pegged at 100

percent.
