Configuration Parameter File Reference
Size of memory for journal buffers.
Amount of memory allocated for journal buffers. The default is 64 MB. Increasing this setting means increasing the amount of journal data that can be held in memory, which improves journaling performance but increases the amount of journal data that could potentially be lost in the event of a system failure. If you edit this setting, you must restart InterSystems IRIS to apply the change.
Range of Values
8 MB (for 8bit instances) or 16 MB (for Unicode instances) up to 1024 MB.
