8i to 10g full upgrade but no indication whether it is successful or not

Hi all Oracle DBA and developer gurus,

Hello everyone. I have a few questions I have to answer in what concerns the result of the migration of the database. Yesterday, I just migrated our 8.1.7.4.0 existing 10.1.0.2.0, using the database 10 g upgrade Assistance. Initially, there are a few hicups, but in the end, the migration went smoothly and completed in no time.

My first question is, although it said the migration of the database is successful in the end, is there an indication in the database or anywhere to prove that migrating to 10g is really successful?

My next question is that, because my old base database 8i uses WE8ISO8859P1 characterset and he warned me to change all NCHAR columns in the user tables to one of the supported types. It's a fair assumption that if my 8i database lacks all the user tables with NCHAR, NVARCHAR2, or NCLOB columns, I can safely ignore the warning messages (which I did) and continue the upgrade process.

Thank you for your help and your time in research and answer my question. Good day.

Best regards
John

Hi John,.

first of all, let me ask the question why you are moving to a version that will not be Premier Support in January 2009 - why do not move you to 10.2.0.4 instead?

The DBUA should tell you that the upgrade was successful - otherwise run utlu101s.sql or see DBA_REGISTRY if all components have been upgraded successfully.

National character set conversion is required because your National Characterset in 8i had most likely been WE8ISO... and since 10g only UTF8 and some other unicode charactersets are allowed. But you can check if you have used NCHAR, NVARCHAR2, and NCLOB columns somewhere.

Kind regards
Mike
