When using the technique shown in this command file, make sure to spread the
process workload across all available processors. If there are too many processes to
start in processors 0 and 1, queuing and memory-contention problems can result. For
additional suggestions on using parallel processing to enhance operational efficiency,
refer to the Availability Guide for Change Management.
Investigate Product-Specific Techniques
Certain products provide commands that can reduce the time required to start up or
shut down their services. For example, the HP NonStop TS/MP product provides the
COOL START option and the SHUTDOWN2 command to shorten startup and
shutdown times, respectively. Using the COOL START option, rather than COLD
START, to restart an existing transaction-processing system is much faster. The
SHUTDOWN2 command is faster and more reliable than the SHUTDOWN command.
Both of these techniques are described in the TS/MP System Management Manual.
Familiarize yourself with the products and applications that run on your system to
identify time-saving techniques for speeding startup and shutdown operations. Refer
to the relevant documentation.
