WAIT specifies to DFSMSdss the length of wait and the number of passes to obtain control of a data set.

numsecs

Specifies a decimal number from 0 to 255 that designates the interval, in seconds, to wait before attempting another pass through the list of selected data sets.

numretries

Specifies a decimal number from 0 to 99 that designates the number of passes to make through the list of selected data sets. Each pass is an attempt to obtain control of a data set.

For logical data set dump operation, the WAIT keyword has a different meaning when: (1) data sets are being serialized, (2) multiple data sets are being processed, and (3) WAIT(0,0) is not specified. In this case, DFSMSdss makes multiple passes through the list of selected data sets. On each pass, DFSMSdss processes the data sets that (1) can be serialized without waiting for the resource and (2) were not processed before. At the end of a pass, if none of the data sets could be processed without waiting for a resource, then, in the next pass, at the first occurrence of a data set that was not processed, a WAIT will be issued. That data set and the remainder of the list will be processed if possible. The above procedure will be repeated until all data sets are processed or the WAIT limits are reached. For example, if WAIT(3,10) is specified and 5 data sets are left to be processed, up to 10 passes are made. On each pass, an unprocessed data set is waited upon for 3 seconds. Thus, only a 30-second maximum will ever be waited, not 150 (5 times 3 times 10).
