Repair/reset oracle DB instance?

Question

Hi Everyone,
I mistakenly ran a schema drop script against my oracle instance and managed to drop a series of tables that I didn't intend to. At this point the instance has stopped accepting connections and I'm trying to find the best way to restore or reset it. The data that is in the database is disposable test data but I would like to somehow salvage instance itself. Unfortunately I'm not familiar enough with Oracle to know exactly what the tables did that were dropped or how I can recreate these. I included the output from the drop script below (the portion that printed out to my terminal before I managed to kill it off). Thanks for your help!

Answer 1

Hi Everyone,
Thanks for your replies. I understand completely that the database is trashed and is likely non-recoverable. The reality of my situation is that this is a development DB that I use for my testing and did not contain anything important. However, until I can either destroy it and create a new one or fix the one I have my testing is on hold. I've tried to find information about how to remove and re-create a database instance but what I've found so far looks pretty questionable. My understanding at this point is that my database is hosed but the extend of the damage is constrained to that database instance (i.e., I should still be able to create a new empty database from my existing software install). If there is no way to salvage the DB instance can someone point me to a way to completely remove it? I'm working off an ssh terminal so I don't have access to any of the nice UI tools for this. Thanks again.
