About this task
Some properties in the system aren’t visible in an instance by default and must be added to the System Property [sys_properties] table. If a feature requires the addition of the property, you can add a system property.
Important: System properties store configuration information that rarely or never changes. Each time you change or add a system property, the system flushes the cache to keep all nodes in the cluster in sync. This cache
flush has a very high performance cost for one to 10 minutes, which can potentially cause an outage if done excessively. To prevent such outages, don’t use a system property to store configuration information that changes more
than once or twice a month. Instead, use a custom table to store regularly changing configuration information.
