Using Multiple VHS Processes
You can use multiple VHS processes to balance the load on your system. For instance, 
you could have one VHS process for specific applications: $VHS1 could run in CPU0 
and receive messages from telecommunication applications, $VHS2 could run in 
CPU2 and receive messages from production applications, and $VHS3 could run in 
another CPU and receive messages from development applications. Note that each 
VHS process can handle a maximum of 512 opens at the same time. 
If you have multiple VHS processes running on your system, you can choose to have 
these processes use one set of log and prompt files. Figure 1-3 on page 1-6 shows 
how three VHS processes, $VHS1, $VHS2, and $VHS3 share the same primary log 
and prompt files. However, you can create a separate VHS environment for one or 
more VHS processes, with its own set of prompt and log files, as described later.
