This is an Oracle error (ORA-00257) generated when Oracle runs out of space in the filesystem, usually ocurring while trying to archive a redo log
ORA-00257 is caused by situations which are completely contained within the scope and purview of Oracle's products and are outside of Automic's responsibility.
This error is captured in our log files, however, it is being returned from Oracle.
It could indicate the database is out of space. This could happen when the archiver process gets an error trying to archive redo logs.
Contact your Oracle Database Administrator or the Oracle Customer Support team and have them analyze the issue.
Usually, cleaning the Oracle filesystem from previous traces/dumps should fix the issue.
