NOWORKDDN

The NOWORKDDN option causes the extracted keys to be sent directly to the sort routine without first writing these keys to a work data set. Using this option causes the index to rebuild faster. However, restartability is more limited because, without the work data set, restarting at the beginning of the BUILD phase is not possible. The restart will have to redo the UNLOAD phase.

The keys are sent directly to the sort if neither WORKDDN nor NOWORKDDN is specified, and no SYSUT1 DD statement exists in the JCL.

If you use RECOVER UNLOADKEYS for the space, NOWORKDDN is the default for a partitioned index.
