MBeans deprecated in favor of Pega API

Valid from Pega Version 8.1

The use of MBeans for cluster management has been deprecated, although MBeans will continue to function for legacy deployments. The recommended best practice for automating system management is to use the Pega API. For more information, see Pega API.

Tomcat log files moved to work directory

Valid from Pega Version 7.1.2

For Tomcat application server users, the default path for PRPC logs has been changed to the "work" directory for Catalina. For example:

<tomcat>\work\Catalina\localhost\prweb

This directory can be cleaned up during administration. To avoid loss of files, you can redirect logging to a different directory after installation:

  1. Navigate to the <tomcat-home>\webapps\prweb\WEB-INF\classes directory.
  2. Open the prlogging.xml file.
  3. Locate the "appender" definitions section that contains the "@{web.tmpdir}" string
  4. Update the FileNamePattern values to point to the new directory.

For more details, refer to the “Change the default path to PRPC logs” section in the Tomcat installation guide for your database.

Required Oracle optimization parameter

Valid from Pega Version 7.1.3

To optimize performance, set the Oracle parameter optimizer_index_cost_adj to a value between 20 and 25. If this value is not set, the system can run exceedingly slowly, potentially blocking users from login.

Slow WebSphere performance on Mac platforms

Valid from Pega Version 7.1.2

Use the following JVM setting to improve WebSphere performance on Mac platforms:

-Djava.net.preferIPv4Stack=true

Synchronized database and application server settings

Valid from Pega Version 7.1.3

Configure your database and application server to use the same time zone and character encoding to avoid conflicts.

PRServlet not required in PRPC URLs

Valid from Pega Version 7.1.6

PRServlet is no longer required in a URL when accessing PRPC. A URL typically written like this:

http://example.com/prweb/PRServlet?[QueryString]

Can instead be written like this:

http://example.com/prweb/?[QueryString]

This change is effective only for PRPC 7.1.6 and newer versions. Older versions of PRPC still require using PRServlet in a URL.

Support for Apache Cassandra

Valid from Pega Version 7.3.1

The Pega® Platform can now read data from and write data to an Apache Cassandra database. Apache Cassandra is a NoSQL database that you can use when a NoSQL database better meets your scalability and processing requirements.

For a list of supported and unsupported features, see Apache Cassandra support.

Requestor pools management in Designer Studio

Valid from Pega Version 7.3.1

On the new Requestor Pools landing page, you can view and manage requestor pools across the cluster, including on the current node and remote nodes. By using this landing page, you can tune the requestor pools to improve the performance of services. You can clear the requestor pool for a service package and view the requestor pool basic metrics and configured thresholds.

For more information, see Requestor pools management, Clearing a requestor pool, Viewing details for a requestor pool, Tuning a requestor pool configuration.

Module version report generated from Designer Studio

Valid from Pega Version 7.3.1

From the new Class Management landing page, you can generate the module version report that provides information about classes in your system, module versions, and version creation dates. You can generate the report for all the nodes in the cluster or for a selected node that is either current or remote. The report is useful for debugging system problems because it helps identify the module version that is causing problems on a specific node.

For more information, see Module version report.

Improved Clipboard performance

Valid from Pega Version 7.3.1

Clipboard performance has been enhanced to use high-speed, read-only data pages, making processing faster. For some high throughput use cases, performance might be degraded. If performance is degraded, you can use a restricted feature set for a specific read-only data page by selecting Restricted feature set for high throughput on the Load management tab of the data page rule.

For information about unsupported features when using a restricted feature set, see High-speed data page support.
