Inflight resolution technology

The inflight resolution technology of the BMC Recovery Management for Db2 solution enables you to perform a consistent recovery to any timestamp or LRSN/RBA.

The ability to resolve inflight units of work at any point in time or to any log point completely eliminates the need to perform quiesces to establish consistent recovery points during application execution. The ability to avoid quiesces can dramatically improve the availability of your Db2 data.

Inflight resolution technology identifies and resolves uncommitted units of work while performing either a backout recovery or a traditional forward recovery to either a timestamp or a log point.

  • In a situation in which a backout recovery is possible, the Recovery Management solution analyzes the updates within the time between the current and the recovery point (as specified either by a timestamp or by an RBA/LRSN) and backs out the changes. No image copy or tape mount is required, and any uncommitted units of work are resolved.
  • In a situation in which a backout recovery is not possible, the Recovery Management solution identifies and restores the most recent image copy. Recovery Management then processes log records only for committed updates, thereby removing uncommitted data from the space.
