Can a situation persistence value be set in the tacmd createSit command?
This has been identified as a document defect under APAR IV41494
Resolving the problem
This is possible to do and is supported.
It is set with the -p SitInfo parameter of "COUNT="<Situation Persistence Number>"
tacmd createsit -s <SITNAME> -b <BASENAME> -p SitInfo="COUNT=<Situation Persistence Number>"
The documentation in the v6.3 FP02 Command Reference Guide has been updated with these details.
