Introduction
If you are encountering the ORA-00363 error in Oracle, it means that the log file has been added or removed and the database needs to be opened to ensure that the changes are properly applied. This error can be caused by a variety of factors, including issues with the log file, incorrect file permissions, or database corruption.
Causes
1. Log File Addition or Removal
This error can occur when a log file has been added or removed from the database. This can happen if the log file is accidentally deleted or if a new log file is added without updating the database.
ALTER DATABASE OPEN;
2. Incorrect File Permissions
Another common cause of the ORA-00363 error is incorrect file permissions on the log file. If the database does not have the necessary permissions to access the log file, this error can occur.
chmod 660 logfile.log
3. Database Corruption
In some cases, the ORA-00363 error can be caused by database corruption. This can happen if there is a hardware failure, a software bug, or if the database is not properly shut down.
RMAN> RECOVER DATABASE;
Solutions
1. Log File Addition or Removal
