Rama,
Only thing I will check that with Oracle any thing specific regard AIX
platform and any specific Patch for 9i after installatio and before 8i
upgrade.
Else you have export and import option.

I did same what that doc says, i was able to install 9i and 9207 ok and
when upgrading using DBUA iam having problem,
I could create new 9i database using DBCA successfully.
I am doing this on an AIX box. I have backups/Database/8i installation on
same box.
Thanks
Krishna.

Rama,
40GB is not a big size, Depending on the Server and Operating system
Windows / UNIX.
Are you going to do this on the same server or different server.
Backup Export then Install 9i and import is a clean and safe method.
Did the Document URL I send help you.
Good Luck.

Rama,
First thing how big is your Database ?
HOw much down time you can afford ?
Most easy effecient way,
Create new Oracle 9i home and Database with the
tablespaces as
your current 8i database.
Full Export from 8i and Full importl into 9i.
Followin g document can help you.

DB_BLOCK_SIZE is 8K, can not reduce that.
do u have simple steps for upgrade manually.
like setting oracle_home to 9i and run upgradeXXX.sql

First. Lets look at the explanation to ORA-000064 error dose it make
sense.
ORA-00064: object is too large to allocate on this O/S num, num Cause:
The initialization parameter DB_BLOCK_SIZE is set to a value that calls for
more contiguous space than can be allocated on the operating system being used.
Action: Reduce the value of DB_BLOCK_SIZE so that the requested contiguous
space is within the capacity of the operating system.
Secondly. Check the alert log and it will help you in understanding the
sequence of events as they occured and after the error what happen did the
database shutdown or crashed etc.
Fix the DB_BLOCK_SIZE and d o the investigation of the cause of error and
restart the process.
Finally. I hope you have a good backup cold and export of your 8.1.7
database, before you had started your upgrade project. If not still not lost
much take backup FIRST.
Good Luck.
