Chapter 4: Understanding Typed Buffers
The client-server model allows the client to access resources provided by the server. We already learned that communication is accomplished by sending messages through queues. The messages exchanged in Tuxedo are described in the XATMI specification, and Tuxedo has implemented more message types since. These messages are called typed buffers and you can't have a Tuxedo application without them. In this chapter, we will cover the following topics:
- Introducing typed buffers
- Using STRING typed buffers
- Using CARRAY typed buffers
- Using FML32 typed buffers
- Importing and exporting typed buffers
By the end of this chapter, you will have a good understanding of the typed buffers available from Python code. We will explore the features and most common pitfalls of FML32. You will learn how to persist messages and build some useful tools along the way.
