Starting and Stopping CA MIM › How You Override Initialization Values at Startup Time › The FORMAT Override Parameter

The FORMAT Override Parameter

To format control files or checkpoint files, specify the FORMAT parameter on the MI START command. The default value for FORMAT is NONE. The following scope parameters are valid for FORMAT:

BOTH

Formats all control files and the local checkpoint files.

CF

Formats all control files.

CKPT

Formats only the checkpoint information in the checkpoint file. You can use the abbreviation CKPT for this operand.

NONE

No formatting is done.

Again, when control files, checkpoint files, or both are formatted, CA MIM acquires information from the parameter data sets and creates a GMR representing various aspects of the MIMplex. The location of the GMR depends on the CA MIM communication method selected. Therefore, proper formatting depends on the communication method that is selected and whether checkpoint files exist.
