Memory Guard

Administrators use this system setting to determine if Oracle Analytics enforces request-level memory usage limits.

Note:

Oracle recommends that you validate Memory Guard thresholds before the feature becomes enabled by default in a future release.

When you enable Memory Guard it provides the following protections:

• Stops memory-intensive or long-running queries that exceed configured thresholds to help prevent broader system impact.
• Returns an error message when a request exceeds the configured thresholds.
• Maintains platform stability under heavy or concurrent workloads by preventing uncontrolled memory consumption from affecting overall execution.

Valid Values

• On — Oracle Analytics stops requests that exceed the configured memory usage limit and returns an error message.
• Off — Oracle Analytics allows requests to continue even if they exceed the configured memory limit. Default
