How the facility should be executed depends on the characteristics of the application. Figure 15-15 shows the execution method and selection criteria.

Figure 15-15 Execution method and selection criteria

Explanation

1. The following shows an example of command execution when interval analysis and merge analysis are used:
   

   pddbst -r ALL -e 2 -w 100,100 -n 5

   Explanation:
   To minimize the effects on online jobs, the facility analyzes 100 segments of data and then pauses for 100 milliseconds, then repeats this process. This example executes the facility for 5 days to reduce the execution time per day. This command is executed once a day for 5 days.
   
2. The following shows an example of command execution when interval analysis is used:
   

   pddbst -r ALL -e 2 -w 100,100

   Explanation:
   To minimize the effects on online jobs, the facility analyzes 100 segments of data and then pauses for 100 milliseconds, then repeats this process.
   
3. The following shows an example of command execution when merge analysis is used:
   

   pddbst -r ALL -e 2 -n 5

   Explanation:
   This example reduces the execution time per day by executing pddbst over 5 days. The command in this example is executed once a day for 5 days.
   
4. The following shows an example of command execution during normal operation (neither interval analysis nor merge analysis is used):
   

   pddbst -r ALL -e 2

   Explanation:
   This is the normal execution method where a single execution of pddbst completes the processing.
