I corrupted a redolog on purpose on a test service 4 some exercise.
I made a coldback of the redo this morning. I then replaced the corrupted redo with the backup redo. No archive enabled

Problem: Database in mount,not open mode.
Can anyone assist me in recovering this db (if possible).

Note: This is an area that I'm very bad at because I never get to practice

my guess its a media recovery and that I'm screwed!!

ORA-00322:log 3 of thread 1 is not current copy
ORA-00322nline log 3 thread 1:'C:\ORACLE\ORADATA\IAMMV3\REDO03.LOG

Please help if possible
