Socket

The Socket Screen displays statistics about requests made to the Socket Server.
The Sun MTP Socket facility allows application programs to make requests over a
socket connection. The request must adhere to a standard format, and must be 
made to a known port. An argument to unikixmain, -p, identifies the known port.
The Socket Server accepts three different types of requests: Immediate (IM),
Interval Control (IC), and Transient Data (TD). An IM request establishes an
immediate link to a Transaction Server. An IC request places a transaction on
the Sun MTP Startq. A TD request writes data to a specific transient data queue,
usually an Intrapartition queue. For each type of request, the Socket Screen
displays the following statistics:

   Requests   -> Number of successful socket requests
   Failures   -> Number of socket requests that fail due to bad parameters
   Characters -> Total number of data characters sent with successful requests
   Avg Chars  -> Average number of characters sent per successful request

The Socket facility also allows a site to customize an exit routine that can
gate access to the Socket facility. This routine can perform a security check
to ensure that the Socket facility only honors validated requests. The security
exit routine either allows or refuses a request. The "Exit Failures" count shows
the number of refused requests (for all types of requests).
