Before you create a 3270 server or custom server to access business information,
you need to perform an analysis of your requirements, to determine how you
can most effectively use a server.
The analysis involves identifying information such as:
- Remote data required by a voice application
- Where the required data resides
- Existing applications that access the data
- Data the server needs to satisfy a request
- Processes required (both new and existing) to satisfy a request
- Whether voice data is to played or recorded on multiple channels at the
same time: a multiprocess custom server makes this easier to manage
- Whether database access is on a serial link, in which case a single process
will suffice, or on a multilink or virtual session, in which case the server
needs to be multiprocess (3270 host access is multiprocess)
- How the server is to be activated (such as by a state table or a timed
event)
- How to respond to both successful and unsuccessful attempts to provide
the requested information
- Considering custom server resource requirements, things such as CPU, memory
and page space
- Any additional processing you may want to perform as a result of a request
(such as maintain a count of types of requests for business activity statistics).
When you have identified the information that defines the requirements
for a server, you can determine whether a 3270 server or custom server best
suits your needs.
