The Oracle Archive Redo logs are filling up the disk 100%, Clarity would generate a lot more Archive Logs, and there is no more space left in the folder which causes the entire database server to freeze
Release : Any
db_recovery_file_dest_size, or how the archiving is set up.
Question: Why is the Oracle Archive logs directory filling up overnight with no Clarity application usage?
This could be explained by processes or scheduled jobs, it is typical for Clarity application to be running scheduled jobs or processes which can account for large amounts of transactions. This happens without any user activity. Note Clarity is an application able to handle high volume of SQL transactions from user activity/jobs/processes.
