7.1 ontape broken? or just useless?

Greetings, Does anyone have experience using ontape -s and ontape -r to "twin" a database onto new hardware? Specifically, I'm trying to restore a level-0 ontape archive. The archive was made on a Sun 10/512 running Solaris 2.4, latest patches, OnLine 7.10UD1. I'm trying to restore onto a Sparcserver 20 with identical software. All dbspaces are raw disk devices, using identical alias names. The restore completes without errors on the Sparc-20. However, when I try oninit -s, I get "Fatal error initializing shared memory." The logfilesays nothing constructive, and no errors appear in syslog -- the database simply won't come up. Informix tells me that this "isn't supported." How, I rejoin, are we supposed to do disaster recovery? If my Sparc-10 is struck by lightning, I'm extremely unlikely to restore to another Sparc-10, since they're no longer being made. Has anyone done this successfully, or run into this problem? Advance thanks! If there's interest, I'll post a summary of Informix's eventual response. -- Mike -- mblakele@best.com http://www.blakeley.com
