Restricted SMA access

Valid from Pega Version 7.1.5

System Management Application (SMA) remote connections are not supported on JBoss EAP 6.x. This means SMA users may only monitor locally connected systems. Ensure that the "Local JVM Connection..." option is selected when configuring PRPC nodes:

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.

High number of busy waits when using Oracle SecureFiles

Valid from Pega Version 7.2.1

You might experience a high number of buffer busy waits when using Oracle SecureFiles for BLOB storage. An Oracle buffer busy wait occurs when a session cannot access a database block in the buffer cache, because another session is either reading the block into the buffer or changing the buffer. As a best practice, use Oracle 11.2.0.4 or later, because earlier versions have more problems with SecureFiles. In addition, to minimize the number of busy waits, set the hidden Oracle parameter _securefiles_concurrency_estimate to 50, and partition the table by using a composite range hash partition that is based on the pxCreateDateTime and pzInskey columns.

For more information, see Troubleshooting: High number of busy waits when using Oracle SecureFiles.

Extract marker file not created at startup

Valid from Pega Version 7.2.1

The extract marker file (PegaRULES_Extract_Marker.txt) is not created at startup, because the rule utility libraries no longer need it. If you used to use the extract marker file to clear the static content file-based cache, to look up lists, or to control starting activities with web nodes, you can delete the contents of the PegaRULES temporary directory instead.

Upgrade/update fails if PostGIS is applied to PegaRULES or PegaDATA schema

Valid from Pega Version 7.2.1

If you use the PostGIS extension to a PostgreSQL database, upgrading or updating the Pega 7 Platform fails if the extension has been applied to either the PegaRULES or PegaDATA schema. PostGIS can be applied to any other schema.

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.
