Using the Checkpoint Checker › Technical Overview › Benefits

Benefits

The major benefits of using the Checkpoint Checker are as follows:

• In the long run, all important job steps must implement checkpoint writing and the Checkpoint Checker gives the user detailed information and easy-to-handle control of this process.
• If a runaway job step should be canceled by the operator, the Checkpoint Checker provides immediate online support in determining whether proper checkpoint writing exists or not.

The following additional benefits are provided by the Checkpoint Checker feature:

• No changes in JCL, programs, or OPC schedules
• A fully automatic solution without any manual work
• Insignificant CPU consumption for the permanent Checkpoint Checker process
• No additional DASD space is necessary if Performance Management Assistant is already installed
