OSI/TS Installation Considerations
If the PAM device is not operative while a TSP process has the ports opened, the TSP
process attempts to delete them as soon as the error condition is detected. The TSP
process also tries to recreate the PAM ports during the next attempt to establish a
connection.
OSI/TS Installation Considerations
OSI/TS does not need to be installed using SYSGEN as do the underlying subsystems.
However, in D-series systems, TSP processes automatically run at a high PIN.
To permanently alter the default setting to run at a low PIN (supported by both D
systems and C systems), use the BIND utility to alter the HIGHPIN attribute of the TSP
object file.
To temporarily change the default setting to run at a low PIN, specify HIGHPIN OFF in
the TACL RUN command.
See the subsection Starting TSP Processes
, later in this section.
OSI/TS Performance Considerations
Good performance is not accidental. Attention to performance begins when you initially
configure the subsystem, and continues throughout its lifetime with on-going monitoring
and adjustments over time. Systems are not static, they change as new applications are
added and as increased demand is put on the existing applications and systems.
This subsection describes factors that must be taken into account when configuring your
OSI/TS subsystem for optimal performance. This information will help system
managers to make decisions about how to configure the subsystem components to best
serve their specific subsystem performance requirements.
Initial Configuration Attributes
Your OSI/TS subsystem configuration attributes define your subsystem environment.
When first setting these attributes, you specify the communications lines and the
controllers using SYSGEN or DSC procedures, and you specify the definition of
processes and subdevices using SCF.
As an overall strategy, it is not advisable to place the OSI/TS subsystem and the TLAM
(for D-series and pre-G06 releases, or PAM, for G06 and above releases) subsystem in
the same CPU. The performance benefits of distributed processing outweigh the
increased interprocessor communication.
To do an effective job when defining and setting the initial system generation and
configuration attributes, you should know and understand the following:
•
The program and system design architecture of all the application systems that will
use the OSI/TS subsystem
•
OSI/TS architecture
