Welcome to Atlassian community.

After checking the above logs , it appears that confluence is not able to establish DB connection.

```
java.lang.ClassNotFoundException: oracle.jdbc.OracleDriver
```

Can you please check if the oracle jar is present in the lib directory:

\<installdir\>\\confluence\\Lib

If the file exists check the directory and file permissions are all fine. You might want to check the [database-jdbc-drivers](https://confluence.atlassian.com/doc/database-jdbc-drivers-171742.html) Kb article which deals with such issue's.

You might want to check the below KB article as well.

[Unable to start due to net.sf.hibernate.exception](https://confluence.atlassian.com/confkb/unable-to-start-due-to-net-sf-hibernate-exception-genericjdbcexception-cannot-open-connection-128843899.html)

I hope the above information will help . Have a good day.

Thanks,

Srinath T
