Hi Experts,
Please help me in takeing the backup of a control file, as i am taking online backup, archive mode.
At first i have executed the statement
sql> alter database backup control file to trace;
then i have removed the control files and enterd some data in a table and committed it.
As my oracle is not shutting down, so i shut aborted it.
Now after saving the last file from the udump as obkp.sql i am unable to edit this file and use.
Please help me how to edit and use this file, so that i can startup my database normally.
