Primary key constraint error when using JBoss
Valid from Pega Version 7.1.9
A primary key constraint violation exception might occur in the following situation: you use JBoss EAP 6.4 and SQL Server 2012 with a JDBC 4 driver, and you use two or more file listeners or JMS MDB listeners with concurrent threads that create work objects that use multiple files. If a primary key constraint violation exception occurs in this situation, update the data source configuration file to set the jta parameter to true. For example, set <datasource jta="true" jndi-name-"java:/jdbc/PegaRULES>.
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.
