DFS0463I BUILDQ OR NOBUILDQ KEYWORD REQUIRED

Explanation

You entered the /NRE FORMAT command to warm start IMS, but omitted the BUILDQ or NOBUILDQ keyword. You must specify either BUILDQ to build the queues after formatting the data sets indicated by the FORMAT keyword, or NOBUILDQ to format the data sets without rebuilding the queues.

For the commands /NRE FORMAT SP and /NRE FORMAT ALL, NOBUILDQ is invalid and you must specify BUILDQ.
