Search and Reporting does not index large items

Valid from Pega Version 8.5

When using the Search and Reporting (SRS) microservice in Pega Platform™ 8.5, you might encounter problems with indexing large out-of-the-box rules. The issue is not visible in Queue Processors, but you can access logs to verify which items the system does not index.

DCO and PMF integration is unavailable

Valid from Pega Version 7.1.5

DCO and PMF integration functionality is not available in this release. Related project management controls have been removed from the following:

  • System Settings landing page (Designer Studio > System > Settings > Project Management)
  • Application Profile landing page (Designer Studio > Application > Profile > Specifications)
  • Add/Edit Specification dialog

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:

Use JDBC 4 compliant drivers for better performance

Valid from Pega Version 7.1.7

For better performance, ensure that you are using JDBC 4-compliant drivers.  For more information on supported and non-supported JDBC drivers, please reference the Platform Support Guide.

Use Tomcat 7 for better performance

Valid from Pega Version 7.1.7

For better performance with a Tomcat web server, use Tomcat 7.

Tomcat 6 has a limitation that causes the server to treat the JDBC driver as if it were a JDBC 3-compliant driver, even if the system is using a JDBC 4-compliant driver. Customers using Tomcat will see better performance if they upgrade to Tomcat 7 and use a JDBC 4-compliant driver.

Engine will not start if the incorrect JDBC driver is used

Valid from Pega Version 7.1.7

The engine will not start up if the incorrect JDBC driver is used. The following configurations are unsupported:

  • Using a Multi-tenant Oracle system with one of the Oracle JDBC drivers with issues (see the chart in the Platform Support Guide)
  • Using a Multi-tenant system with a JDBC 3 compliant driver, OR with Tomcat 6 (for more information on using tomcat with Pega 7.1.7, see Use Tomcat 7 for best performance)
  • Using Microsoft SQL Server with a JDBC 3 compliant driver, OR with Tomcat 6 (for more information on using tomcat with Pega 7.1.7, see Use Tomcat 7 for best performance)

When any of these unsupported configurations are encountered, Pega 7 will not start. Before this change, the engine would appear to start up properly, but would encounter issues during other parts of the engine startup or during actual use of the system.

IBM WebSphere Application Server V8: Edit the URL for Enabling System Management Application

Valid from Pega Version 7.1.7

WebSphere 8 does not correctly resolve the URL to enable System Management Application. As a workaround, when you configure the application server, you can do either of these actions:

  • Enter the full URL in the format:
    ​http://hostname:port/prsysmgmt/getnodes.action

  • Set the com.ibm.ws.webcontainer.redirectcontextroot property to true.

Open ports required for cluster communication

Valid from Pega Version 7.1.7

In a Pega 7 system, there can be multiple servers, or nodes, and each node can contain multiple JVMs.  In Pega 7.1.7, the port range 5701-5800 needs to be left open for cluster communication.   The number of available ports in this range needs to be greater than or equal to the greatest number of JVMs on any one node in the cluster.  So for example, if there are 3 JVMs on one node, and 7 JVMs on another node, there need to be at least 7 ports available.  By default, the system will begin with port 5701, and then look for the next port in the sequence (5702, followed by 5703).

 

If these ports are not available, you will see the following error:

 

ERROR   - PegaRULES initialization failed. Server: ABCDEF123

com.pega.pegarules.pub.context.InitializationFailedError: PRNodeImpl init failed

< . . . Java dump here . . . >

Caused by: com.hazelcast.core.HazelcastException: ServerSocket bind has failed. Hazelcast cannot start! config-port: <port>, latest-port: <port>

 

Recommended heap sizes

Valid from Pega Version 7.1.7

The heap is a storage area in the Java virtual machine (JVM) allocated for both short-term and long-term (shared) object storage. If the server does not have enough memory allocated to run Pega 7, the system can hang without an error message. If this occurs, your values need to be higher than the recommendations based on your server hardware and the number of other applications on the server.

Pegasystems recommends using these settings:

  • Initial Heap Size (Xms): 1 GB
  • Maximum Heap Size (Xmx): 12 GB (8 GB minimum)

If your application server is using the Oracle JVM, also add the PermSize and MaxPermSize settings:

  • PermSize (-XX:PermSize): at least 256MB
  • MaxPermSize (-XX:MaxPermSize): at least 512MB

Set the JVM memory options to increase the amount of system memory allocated to the application server running Pega 7 by selecting Designer Studio > System > Operations > System Management Application and then selecting a listed node.

See the Pega 7.1.7 Installation Guides for more information about how to make these setting changes.

Screenshot generation runs on local client

Valid from Pega Version 7.1.8

If you generate screenshots to include in your application document, this process still runs on your local client. Additionally, you are still required to use Internet Explorer to use this feature.

We'd prefer it if you saw us at our best.
