Abstract:
1. A method, in a data processing system, for calculating a recovery time of an application system in a computer system for tuning the computer system dynamically, the method comprising: determining, by a recovery calculator of the data processing system, a type of redolog used during a backup process and a corresponding recovery speed value associated with the type of redolog, wherein the type of redolog is one of a plurality of different types of redologs, and wherein the recovery speed value associated with the type of redolog is different from recovery speed values of other types of redologs in the plurality of types of redologs; calculating, by the recovery calculator, the recovery time based on the type of redolog used during the backup process and the corresponding recovery speed value associated with the type of redolog; comparing, by the recovery calculator, the calculated recovery time to a predefined maximum recovery time period; and setting a trigger, in a status monitor of the data processing system, for performing an operation in response to the calculated recovery time exceeding the predefined maximum recovery time period.
