RE: Re: Migration
Hi Stephane, The way you put it here would mean that the internal format of the tablespaces will be big/little-endian independant. That would mean either an extra amount of overhead in the low level IO, or Oracle-specific arithmatic everywhere in the kernel. I doubt whether Oracle would do that. It might (will!) cause severe performance penalties. A few weeks ago I had an interview with Chuck Rozwat. I asked him this specific question. He was quite convinced telling me that the transport mechanism (data pump?) performs the HW-dependent conversions whenever you transfer a tablespace from one platform to another. He told me also that the HW-dependant differences will remain in place, and it isn't possible to have a R/O tablespace opened simultaneously by instances running on different platforms. (Not even Windoze/Linux combined) So the binary incompatability will remain in place. Alas, I haven't got a beta version, so I haven't been able to test it yet :( Regards, Carel-Jan At 06:54 10-11-03 -0800, you wrote: It raises an interesting question. As of today, we have datafiles which are OS dependent and _not_ binary compatible from one system to another. We upgrade to 10g and it will become magically binary compatible. Which means that the upgrade process will do more intimate things than updating some file header block, creating a couple of new tables in the data dictionary and recreating view. Has anybody tried to upgrade from 9.x to 10g yet, on some database of decent size ?

Re: Re: Re: Migration
Well, I don't know about it's performance, but I think this conversion doesn't require any temporary space, because the byte values of some structures in blocks have to be swapped, and this a trivial operation. I think it may still be faster, especially if we are dealing with huge amounts of data, swapping bytes in blocks is faster than reading and parsing data through buffer cache, transferring it over sqlnet and formatting + writing it back to datablocks...

Re: Re: Migration
You can't just copy over the files with os commands and hope that Oracle will somehow recognize them. You have to use RMANs new convert tablespace command to do the byte order conversion.

RE: RE: Migration utility from 7.3.4 to 9i ??
Hi Dick, According to the 9i Migration Utility Guide, the Mig Utility that comes with 9i will migrate 7.3.x database to 9i directly. Unfortunately we had no 7.3.4 database to migrate to 9.0.1. So I have not had a chance to test it myself. We migrated several 7.3.x database to 8.x using Mig Util without any problems. Of course, one can always use export/import for such things. - Kirti -Original Message- Sent: Thursday, February 07, 2002 8:22 AM To: Deshpande; Kirti; Multiple recipients of list ORACLE-L Kirti, I believe the question is: is there any way to migrate from 7.3.4 directly to 9i. Assuming that to be correct the answer obviously is no, unless you want to take the export/import route. The reason is that in migrating from 7x to 8x the rowid's in the database went through a major change that you can't bypass.
