Example 13: Using the LOGSCAN command

Example 13 illustrates the use of the LOGSCAN command. LOGSCAN gathers information about log records that you can use to determine your recovery strategy.

The LOGSCAN command uses the SYSSCAN DD statement included in this example to designate output for the report that the LOGSCAN command generates.
