Viewing Performance Data

562

Free Physical

Memory (KB)

Host

The amount of free physical memory on

the host. To receive this data from a

64-bit AIX host, the bos.perf.libperfstat

file must be installed on the host. See the

Prerequisites section in the chapter for

installing the CIM Extension on AIX in the

Installation Guide.

Free Virtual

Memory (KB)

Host

The amount of free virtual memory on the

host. To receive this data from an AIX

host, the bos.perf.libperfstat file must be

installed on the host.

In Memory Sort

Ratio

Oracle

This ratio shows the proportion of sorts

that are performed in memory.

Optimally, most sorts should be

performed in memory. If the ratio is less

then 90 percent investigate further. You

may need to increase sort_area_size or

pga_aggregate_target (for Oracle 9i if

the workarea_ size_policy is auto.)

Inode Cache Hits

Count per Second

NAS Filers (System)

The number of inode cache hits per

second.

Inode Cache

Misses Count per

Second

NAS Filers (System)

The number of inode cache misses per

second.

Invalid CRC Errors

(errors/second)

Storage Systems

The speed at which invalid cycle

redundancy checking (CRC) errors are

found.

Library Cache Hit

Ratio

Oracle

This gives an indication of how many

times parsed SQL or PL/SQL statements

needed to be reloaded, which requires a

reload/rebuild of the statement. If the

ratio is less then 95% investigate further.

You may need to increase

shared_pool_size.
