RE: DB Movement from Sun to AIX ?

MY QUESTIONS IN CAPITALS BELOW ARE STILL UNANSWERED. Additionally

1. Is there any V$ View etc which shows Status of Refresh (Running, % Complete, FULLY Complete etc)?
2. Any Good Docs, Links on Materialized Views?

(I am looking at metalink, google though)

Thanks again for all the previous responses

Subject: RE: DB Movement from Sun to AIX ?

Folks

Need to migrate a big production Hybrid database from Oracle 8.1.7 on Sun to 9.2 on AIX.

Main issue is that Source & Target DB Boxes/Machines being Located 20 KMs apart there is NO connectivity between them currently NOR being planned.

Existing Options:-

NOTE AIX Storage Box is external to the machine & respective DB Machine is of Very High Configuration.

1. Connect temporarily a Smaller AIX Box/machine with the required external storage Box(which is going-to-become production) at the location of the source SUN Server. After using suitable methods for Data transfer e.g. DB Link, Materialized views, exp/imp thereafter disconnect the external Storage, physically transport/shift it to the Target location & connect it to the High End AIX machine.

Qs SINCE THIS IS AN IO INTENSIVE OPERATION, HOW WILL A SMALLER BOX WITH A FEW CPUs IMPACT THE SPEED OF DATA TRANSFER FROM THE PRODUCTION SUN SERVER? 2) If Above is NOT possible, fire export(exp) of those Larger History Tables which do NOT get updated for past data, transport exp dump manually to target machine & import into Target DB. Thereafter insert incremental records which are added.

3) IS IT POSSIBLE TO USE SOME "UNSUPPORTED" MEANS/PROCESSES(e.g. thru transportable Tablespaces) TO MOVE DATA/DATABASE FROM SUN INTO AIX TARGET MACHINE ? THEREAFTER DATA CAN BE MOVED FROM THIS "UNSUPPORTED" DB INTO ANOTHER NEWLY CREATED DATABASE ON THE SAME SERVER USING CONVENTIONAL MEANS e.g. DB LINK , CTAS etc

Miscellaneous info:-

AIX box is going to be a NEW installation.

It is also NOT possible to physically re-locate the production SUN server to the Location of the AIX Box.

Source Database is on Sun with Oracle 8.1.7

Target DB needs to go to AIX on Oracle 9.2

DB size - 600 GB

Application - Online Hybrid Banking Application

Num of Users - a few thousand Bank Staff users

Application is NOT on the internet. Hence can be brought down for about 6-8 hours

Any advice is welcome.

Thanks
