If you cannot recover the database, you *** CAN *** take a cold backup and open it elsewhere, on a 5.2 box, for example. You only have to make sure

that you loaded the right post_wait extensions. I advise you to use the ones from 9.2. Boot the machine in 32 bit mode. No migration is necessary, cold backup actually works in 32 bit mode. IBM went to great lengths to ensure the
compatibility. I'll risk extreme unpopularity with IBM-bashers, but they did an admirable job. I tried things with AIX 4.3 and the 8.1.7.1 database and it
worked.

I am looking for some expert suggestions for the migration of 300GB database to different hardware. Currently database is 816 OPS on AIX 4.1 nodes. Database is 32bit and performance on this system is really slow. Export for 2GB table takes 2 hours. All the data is on EMC symmetric. We are planning to migrate this database to AIX5.1 Oracle 8174 32Bit. Oracle 816 on AIX5.1 is not supported. 'Cause OS is different we cannot use redirect restore and apply archive logs to bring the database up. Any suggestion regarding migration.

Thanks
