. .
to seeing the number of processors in a system and the percentage utilization of each processors,
. .
. .
you can tell if the processors are on-line or off-line.
. .
. .
You can also monitor the amount of activity on each processor. This statistic can help you
. .
. .
determine whether bottlenecks exist within the system. For example, if your system is configured
. .
in dedicated mode and you see that very little activity is occurring on the boot processor, you may
. .
. .
want to change the mode to shared mode.
. .
. .
In particular, you may want to watch the behavior of your SMP aware applications by checking
. .
the Mutex Information. This statistic indicates that a thread is locking a resource. Any resource,
. .
. .
such as buffers, registers, memory, and devices can be locked by an SMP thread (multiple threads
. .
make up an application). Upon completing an operation, an SMP thread unlocks the resource it
. .
. .
used; however, during the time a resource is locked, no other thread can use it. Resources that are
. .
shared by multiple SMP aware threads need locks to ensure the integrity of an operation being
. .
. .
serviced. For example, the Mutex list may be locked temporarily by an SMP aware thread. This
. .
prevents any other SMP aware thread from changing or adding to that list while the first thread is
. .
. . completing its operation. The longer and more frequently resources are locked, the more likely
. .
performance will be affected. If you are concerned about performance, you may want to consider
. .
removing applications that lock resources.
. .
. .
. .
MONITOR.NLM can also be used to determine whether your system is running SMP aware
. .
applications. Because NetWare always runs on the boot processor, you can check
. .
. .
MONITOR.NLM for any tasks that are being run on the secondary processors. If the secondary
. .
processors are being utilized, your system is running SMP aware applications.

Changing the operating system from intraNetWare SMP to intraNetWare requires the Primary

Operating System option to be changed in the System Configuration. See Uninstalling NetWare
