Summary

The rule collects the Linux "Dusty corner scan retries/sec (Phantom-issued)" performance counter for the XTP engine's phantom processing subsystem.

The XTP Phantom Processor performance object contains counters related to the XTP engine's phantom processing subsystem. This component is responsible for detecting phantom rows in transactions running at the SERIALIZABLE isolation level.

Dusty corner scan retries/sec (Phantom-issued) - The number of scan retries due to write conflicts during dusty corner sweeps issued by the phantom processor (on average), per second. This is a very low-level counter, not intended for customer use.

Overridable Parameters

Name

Description

Default Value

Enabled

900

Timeout (seconds)

Specifies the time the workflow is allowed to run before being closed and marked as failed.

300

Timeout for query execution (seconds)

The workflow will fail and register an event, if the query execution takes longer than the specified period.

60

Timeout for database connection (seconds)

The workflow will fail and register an event, if it cannot access the database during the specified period.
