Db2 HADR Synchronisation mode change based on network delay/huge workload

Hi Team,

Can we explore the possibility of enhancing Db2 HADR so that, in scenarios where network response becomes slow or unreachable, the HADR configuration can automatically switch its synchronization mode from SYNC or NEARSYNC to ASYNC or SUPERASYNC in order to maintain database performance?

This capability should ideally be controlled through a registry variable or configuration parameter, ensuring that customers explicitly enable it with full awareness of the potential risk of data loss associated with asynchronous modes.

    May be we can few more factors like

    network congestion for longer than x seconds

    Or standby delays tolerated up to 2ms

    Additionally, we can consider enabling the feature to revert the synchronization mode back to its original SYNC mode once certain criteria are met.

    This would ensure that, after the temporary shift to ASYNC or SUPERASYNC, the system automatically restores full data protection when conditions stabilize.

    By doing so, we can assure customers of both downtime resilience and performance maintainability, without manual intervention.
