Janet,
If you are at z/OS 1.13 or higher, you could use 'Spin any Spin' and
add an additional operand to SPIN=UNALLOC specification in your long running
started task jcl to do one of the following -
1. spin the dataset at a specified time;
2. spin the dataset at a specified interval;
3. spin every nnn records;
4. spin dataset on command
Hope that helps.
Roger
