Abstract
Disclosed is an enhanced database journaling mechanism that results in reduced secondary storage consumption. The memory management mechanism of the present invention reduces journal size, and accordingly, secondary storage utilization by monitoring the effects to the journal by certain transactions and by making one or more adjustments to reduce those effects.
Claims18
A computer system, said computer comprising:
- a bus;
- a central processing unit;
- computer system memory, said computer system memory being connected to said central processing unit;
- and
- a memory management mechanism stored in said computer system memory, said memory management mechanism adjusting transaction priority to decrease transaction time and thereby permit more efficient journal space utilization.
A program product, said program product comprising:
- signal bearing medium;
- and
- a memory management mechanism stored in said computer system memory, said memory management mechanism adjusting transaction priority to decrease transaction time and thereby permit more efficient journal space utilization.
A computer implemented method, said method comprising the steps of:
- receiving a journal related request;
- and
- adjusting transaction priority to decrease transaction time and thereby permit more efficient journal space utilization.
A computer implemented method, said method comprising the steps of:
- receiving a journal related request for a journal;
- adjusting transaction priority for a specific transaction to decrease transaction time of said transaction;
- and
- deallocating memory associated with said specific transaction upon completion of said specific transaction.
