Using Measure
You may find it useful to use Measure when you are evaluating whether to change
from one operating mode to another. Refer to the Measure User's Guide and the
Measure Reference Manual for information on using Measure.
Supporting Multiple
INMC Links
INMC links are supported by processes that support the IS function. Both NC and IS
processes support the IS function. Each process class is designed to comfortably
support one INMC link. To support more than one INMC link, NonStop
NET/MASTER MS should either contain, or be configured to dynamically create,
additional NC or IS processes.
Note The EMS message NNM0553, described earlier in this section, is displayed if you exceed recommended
capacity limitations (more than one INMC link in the NC or IS process).
The IS-supporting process used depends on the operating mode:
In basic mode, the single NC process supports the IS function. If the NC process is
dynamic, each additional INMC link is supported by an additional NC process. If
the NC process is static, additional INMC links are supported by the existing NC
process.
In extended basic mode, both NC and IS processes support the IS function. Each
additional INMC link is normally supported by an additional IS process, not an
NC process.
In advanced mode, the IS process supports the IS function. Each additional INMC
link is normally supported by an additional IS process.
See “Configuring Static and Dynamic Application Processes,” earlier in this section,
for information about configuring NC and IS processes.
As INMC links are started with the LINK START command, each link becomes
associated with an available static IS-supporting process (either NC or IS). After the
static process is associated with a link, the static process is no longer preferred to
support other links. After all static IS-supporting processes have become associated
with a link, the NCP starts an IS-supporting process to accommodate additional links,
provided that your configuration enables dynamic creation of IS-supporting processes.
The following example illustrates the sequence of events.
Suppose NonStop NET/MASTER MS is operating in advanced mode. Suppose
further that the configuration provides three static IS processes named $ZIS1, $ZIS2,
and $ZIS3. The configuration also enables dynamic creation of IS processes. This
sequence of events occurs when you issue five LINK START commands.
1. The first LINK START command starts an INMC link that becomes associated
with $ZIS1.
2. The second LINK START command starts an INMC link that becomes associated
with $ZIS2.
