Because of the "growing pains" with 5.2, is support for z/VM 4.4 going to be extended beyond 9/06?

There have been a number of HTT001 abends due to various page translations too that you should also get the fixes for.

Considering your system up-time requirements, you would do well to build a test system with all the fixes applied and let it settle in a little with your hardware/software configuration. z/VM 5.2 was a jump in advancement for storage relief, so it is certainly a good thing to go to but it is still seeing a few "growing pains". We have z/VM 5.2 on 12 systems here - all but 1 are production systems. Generally they have been running very well. As I mentioned, a couple HTT001 abends hit us along with a pesky HPC010 that is still eluding us. _______________________________________ James Vincent Systems Engineering Consultant Nationwide Services Co., Technology Infrastructure Engineering Mainframe, z/VM and z/Linux Support One Nationwide Plaza 3-25-02 Columbus OH 43215-2220 U.S.A Voice: (614) 249-5547 Fax: (614) 677-7681 mailto:[EMAIL PROTECTED]
