Chapter 3: Tuxedo in Detail
There are a couple of Tuxedo's implementation details that it is useful to know when it comes to making the correct technical decisions. One of them is the BBL process present in all Tuxedo applications, and the other is the use of Unix System V IPC queues. Monitoring and sizing Tuxedo's queues is one of the most important tasks for the administrator of a Tuxedo application.
In this chapter, we will cover the following topics:
- Learning what BBL is
- Understanding queues
- Introducing services and load balancing
By the end of this chapter, you will have practical experience of how BBL contributes to application availability. You will understand the relationship between queues and services and the ways in which that can be expressed in the Tuxedo configuration and how load balancing works. You will also know how to get information about queue size and how to change it.
