Executive Summary
The DBA Redo Log Files report details the physical configuration of the Online Redo Logs. Redo logs are critical for data integrity; if they are lost, the database cannot recover from a crash. This report verifies that logs are properly multiplexed (mirrored) and located on appropriate storage.
Business Challenge
- Availability: “Do we have at least two members for each redo log group to protect against disk failure?”
- Performance: “Are the redo logs on the fastest available disk (e.g., SSD or NVMe)?”
- Configuration: “How large are our log files? Do we need to resize them?”
Solution
This report joins GV$LOG and GV$LOGFILE.
Key Features:
- Group Status:
CURRENT,ACTIVE, orINACTIVE. - Member Path: The full file system path to the log file.
- Size: The size of the log file in bytes.
Architecture
The report queries GV$LOG and GV$LOGFILE.
Key Tables:
GV$LOG: Log group metadata (Sequence #, Size).GV$LOGFILE: Physical file locations.
Impact
- Data Protection: Ensures that a single disk failure won’t cause data loss or downtime.
- Write Performance: Confirms that redo logs are isolated from other heavy I/O workloads.
- Recovery: Essential information for performing media recovery.
