ABSTRACT:
A system and method for checkpoint tuning in a computer environment comprising a processor coupled to a statistical database and at least one database or table manager and data log files. The data log files store data relating to the operations of the database or table manager. The processor executes a module that captures data comprising the number of operations, the time taken by the checkpoint process, folded journal entries, long running transactions, and the ratio of WRITE:READ operations. The processor then stores the captured data and processes the collected data, generating statistics therefrom. The statistical data is stored in the statistical database. The system selects checkpoint intervals based on the data statistics; and implements the checkpoint intervals.
