IOACTIVITY command

Usage

Use the IOACTIVITY command to reduce data and generate I/O Activity reports.

• You can specify this command only once in a job step.
• However, you can use it in the same job step with commands of the other report sets.
• You can filter records with the GLOBAL command first. This can minimize your report output and reduce processing time. See GLOBAL command for more information.
