Hello,
You made a shutdown abort of your database:
SQL> shutdown abort;
ORACLE instance shut down.I think it would be safer to make a clean stop of your database before making any changes on your redolog files.
After a shutdown abort your database is not consistent. So your redolog files are necessary to open it.
More over, before renaming the redolog files you must copy it (by OS command) to it's new location else
you can have such error:
ORA-27041: unable to open file
OSD-04002: unable to open file
O/S-Error: (OS 2) The system cannot find the file specified.Hope it can help.
Best regards,
