We found CLOSE TYPE=T was required if the dataset is disk mirrored and you want to be able to run the restart off the mirrored system. Due to the overhead, we only recommend our customers do this if they are using disk mirroring.

So far so good, but I would like some advice from I/O gurus on the list. One of the functions in write mode is "flush()", which CHECKs all of the outstanding WRITES. (and a "NOTE" in write mode automatically causes a flush()). What are the benefits of adding an option to do CLOSE TYPE=T after flush() and before the NOTE? How does this affect "restart" processing if the job abended and wanted to POINT to the last NOTE and restart? Do I always want to do CLOSE TYPE=T between flush() and NOTE or make it an option (is it expensive?) Thanks in advance for your kind advice. Kirk Wolf Dovetailed Technologies http://dovetail.com
