Searching for Static and
Dynamic Processes
When the NCP receives a request to handle certain types of work (for example, a user
attempts to log on to NonStop NET/MASTER MS or you attempt to start an INMC
link), the NCP tries to find a process to satisfy the request in the following order:
1. By using an existing static process that has the capacity to handle the request.
If an existing static process has the capacity to handle the request, the search stops:
otherwise, the search for a process continues.
2. By using an existing dynamic process that has the capacity to handle the request.
If an existing dynamic process has the capacity to handle the request, the search
stops: otherwise, the search for a process continues.
3. By starting a new dynamic process, using the process definition of a dynamic
process that is not currently running.
If a new dynamic process can handle the request, the search stops: otherwise, the
search for a process continues.
4. By starting a new dynamic process, using the process definition of a dynamic
process that is currently running.
If a new dynamic process can handle the request, the search stops: otherwise, the
search proceeds to Step 1 and stops. NonStop NET/MASTER MS then selects an
existing static process to handle the request even though it exceeds the
recommended capacity limitations of the static process.
Exceeding Recommended
Capacity Limitations
If you exceed recommended capacity limitations when using only static processes (for
example, more than 10 interactive user logons or more than one INMC link in a
process), an existing static process handles the excess workload but response time and
throughput in that process may severely degrade.
The EMS message NNM0553—NNM0553 CONFIGURATION ERROR: DYNAMIC
PROCESS NEEDS TO BE CONFIGURED FOR $ pxxx —is displayed if you exceed
recommended capacity limitations. This message indicates that if the process $pxxx
was dynamic, not static, NonStop NET/MASTER MS could satisfactorily handle the
excess workload: the NCP would create an additional dynamic process that would
handle the excess workload. To change the process presence of $pxxx, shut down
NonStop NET/MASTER MS, change the configuration of $pxxx, and restart NonStop
NET/MASTER MS.
