Hi Boby,
I'd recommend looking to see if any additional error messages are logged in your DSpace logs, or maybe your Oracle logs. Oracle seems to be saying some table is missing (
java.sql.SQLSyntaxErrorException: ORA-00942: table or view does not exist ) . But, in the message you sent, it doesn't say which table is missing -- which makes it harder to debug this issue. Sometimes a missing table is a bug in our code, but other times, it might simply be a permission or connection issue with the database. If you can find additional errors, it could help to send them to this list to allow us to narrow down the issue.
I will also note that most DSpace development occurs on PostgreSQL these days. Unfortunately, our volunteer dev team no longer includes Oracle experts. But, that said, if there are Oracle specific issues with the installation, we'll obviously work to get them resolved.
