3.1 Topics covered by this chapter

This chapter describes the scheduling and load balancing of requests that CTM can implement. CTM improves system stability and operability by appropriately scheduling the executions of requests from clients, and then distributing these requests to multiple J2EE servers.

For an overview of request scheduling using CTM, see 3.2 Overview of request scheduling using CTM. For the process configuration for using CTM, see 3.3 Process configuration for using CTM.

Each section in this chapter describes a specific CTM function. The following table lists the functions described and their respective sections.

Table 3‒1: CTM functions

Function name	See
Controlling the flow volume of requests	3.4
Controlling priority of requests	3.5
