Interface MQLogWriteIntegrityEnum
- All Superinterfaces:
- Enumeration
public interface MQLogWriteIntegrityEnum
- extends Enumeration
Some hardware guarantees that, if a write operation writes a
page and fails for any reason, a subsequent read of the same
page into a buffer results in each byte in the buffer being
either:
- The same as before the write, or
- The byte that should have been written in the write operation
On this type of hardware (for example, ssa write cache enabled),
it is safe for the logger to write log records in a single write
as the hardware assures full write integrity. This method
provides the highest level of performance.
