Using Automatic Analysis

To each wait reason, you can associate any number of the available resource panels. Their order of entry in this chart indicates panel display order. When you are designing the A-matrix, it is important to keep in mind which resource panels actually apply to the area you are investigating. You create, modify, and display the A-matrix by using a set of utility commands as described in A-Matrix utilitieson page 119.

Automatic resource reports (AUTO keyword)

You can use these A-matrices in various ways. You have already seen how the system navigator uses them when you enter an R to decide which resource panels should be displayed for detecting a bottleneck. If running in batch mode, the AUTO keyword substitutes the system navigator. The A-matrix also comes into effect when you use automatic resource reporting. This feature automatically generates the resource panels associated with the most significant wait reason.

For example, if you display the previous detail report and want to automatically display resource panels associated with the most significant wait reason, you can enter AUTO to automatically display the resource panels. This is essentially the same thing that happens when you enter an R in the first space of the bottleneck line, as shown in Figure 34 on page 113.

In the following example, the most significant wait reason is database I/O waits. Assume that the resource panels for this wait reason, as specified in the A-matrix, are General System Information (RINF) and SRM Statistics (RSRM). When you enter AUTO as part of the command as in this example:

DIS GRP(1) SDATE(01/02/97) STIME(1000) - EDATE(01/02/97) ETIME(1100) AUTO COMB these panels appear automatically as shown in Figure 37.
