I've lost my REDO LOG files, how can I get my DB back?

The following INIT.ORA parameter _allow_resetlogs_corruption = true may be required if your current redo logs are corrupted or blown away.

Caution is advised when enabling this parameter as you might end up losing your entire database

Please contact Oracle Support before using it. _allow_resetlogs_corruption = true 

How to fix: ERROR 1045 (28000): Access denied for user ‘root’@’localhost’ (using password: YES)

Open your terminal and type mysql -u root -p Enter your password. Hopefully your MySQL is logged in now.
