Node description cannot match application server node name
Valid from Pega Version 6.3 SP1
A node's Short Description should not be the same value as the application server node name. If the node's Short Description is changed to be the same value as the application server node name, then the node description is automatically changed back to the original value after a system restart.
Rule revalidation after updating properties without restarting nodes
Valid from Pega Version 8.2
When you update certain property attributes, such as a property's maximum length, rule types that reference the property might not reflect the change. You do not always have to restart nodes to revalidate the referencing rules when they cannot be resaved, for example, when they are in a locked ruleset. For Pega Platform™ 8.1 and later, for non-stream rules, such as activities, data transforms, and so on, use the reassemble API in Admin Studio or truncate the assembled classes table.
For stream rules, such as sections, harnesses, paragraphs, and so on, reassemble the rules and restart the nodes. For more information, see More about properties.
For previous versions of Pega Platform, use the System Management Application (SMA) to revalidate stream and non-stream rules.
