T0470AAB or subsequent SPR, you do not need to start Parallel Library TCP/IP by
running your startup script.
If you are falling back to G06.09 or G06.08 (or to T0460AAA), you also need to run
your Parallel Library TCP/IP startup scripts again to repopulate the configuration
database.
Re-Populating the Configuration Database
Starting TCPMONs, adding and starting subnets and routes, and adding entries is
typically automated by using the TACL script containing SCF commands. Normally,
running the startup script results in a subsystem whose configuration database mirrors
the online configuration.
If after starting Parallel Library TCP/IP, you also manually alter the online configuration
but do not correspondingly change the startup script, the online configuration will differ
from the startup script and you must update this startup script before running it again.
The following sample TACL macro extracts online Parallel Library TCP/IP subsystem
configuration data and writes it to a log file. Compare the data in this log file to the
startup script and update the script if necessary.
For complete information about managing the persistence management feature of
Parallel Library TCP/IP, see the TCP/IP (Parallel Library) Configuration and
Management Manual.
Resource Management
With Parallel Library TCP/IP, processor utilization measurements of client applications
might show higher numbers because the TCP/IP processing is now being done in the
context of the application. In the conventional TCP/IP environment, this work was
attributed to the TCP/IP process.
From a systems perspective, the overall processor utilization should be lower because
the number of dispatches and context switches is minimized.
