ORA-24324 service handle not initialized ORA-01041 internal error. hostdef extension doesn't existWhat could be the problem and how to solve it ?
You should check the alert log for messages that will indicate why the database was not able to start. I suspect that one of the background processes panicked and caused a crash during startup. The alert log usually provides useful information in determining the root cause. It could be as simple as a directory not being created or a file access issue.
