Hi Dave, We're trying to teach some of our Java programmers MVS/JCL and Cobol. We're familiar with the Hercules emulator, but it obviously has many limitations. Do you guys ever do timeshare?

We recently implemented ZFS file sharing for the first time here. We run GDPS/XRC to replicate our dasd from HQ to DR site and then often "flash" the farm to a set we can IPL our recovery system from. Because the of replication, our ZFS files are obviously never closed properly before being used when we IPL the recovery LPAR. The nature of our 24/7 environment and GDPS/XRC means that the flash of the dasd farm will ALWAYS be "fuzzy". The contents of block 0 in each ZFS file will always contain data So we experience the dreaded IOEZ00807I message and a 65 second delay per mount. We have so many ZFS files in use that this takes almost 2 hours to complete a successful IPL of the recovery system. What do other shops do about this? I would hate to have to IPL a minimal system just to mount/unmount the files properly before IPLing the recovery PROD system. Is there a parm anywhere to tell ZFS to ignore integrity checking at IPL?
