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.

Turn off saved connections in WebLogic

Valid from Pega Version 7.1.1

PRPC caches connections in thread-local storage. When using a WebLogic application server, set database/savedconnections to FALSE to avoid incorrectly saved, container-managed transactions. You can make this update through JNDI settings or by adding an entry to the prconfig.xml, for example:

<env name="database/savedconnections" value="false" />

IE8 hangs on large imports

Valid from Pega Version 7.1.1

IE8 users may experience a hung process when running the Designer Studio > Application > Distribution > Import wizard. This issue is related to low-capacity networks and large (300+ MB) archive files.

Although the processing symbol prevents you from proceeding to the next step in the wizard, the file is still imported to the server. As a workaround, you can:

  1. Wait approximately eight minutes for the file to import.
  2. Close and restart the wizard.
  3. Click Next to skip the upload step.
  4. Select the name of your file from the list of import files.
  5. Complete the remaining steps in the wizard.

Required DB2 settings

Valid from Pega Version 7.1.1

For customers using the DB2 Version 4 drivers (“db2jcc4.jar”), it is necessary to set the custom connection property useJDBC4ColumnNameAndLabelSemantics to “false”.   

For customers using DB2 with WebSphere, the useJDBC4ColumnNameAndLabelSemantics property in the DB2 data source needs to be changed from a Boolean to an Integer and set to "2". 

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>

 

Using Kerberos authentication with your database

Valid from Pega Version 7.1.1

Pega 7 supports Kerberos functionality. Kerberos is a computer network authentication protocol which allows nodes communicating over a non-secure network to prove their identity to one another in a secure manner. 

 

To use Kerberos for authentication, you must use the command line to install or upgrade Pega 7.

 

To use Kerberos authentication:

1.  Change the setupDatabase.properties file.

a.  In the “Uncomment this property section” of the file, uncomment the jdbc.custom.connection.properties property.  Based on your security infrastructure, different properties may be required as parameters to this property; provide the needed properties as semicolon-delimited name/value pairs:
 

jdbc.custom.connection.properties=prop1=val1;prop2=val2;prop3=val3;
 

Example:  For an installation on a MSSQL database server from a Windows client machine (where both machines belong to the same Windows domain), using the Microsoft JDBC driver, the property may be set as follows:
 

jdbc.custom.connection.properties=integratedSecurity=true;

 

b.  Comment out all the username and password properties where they occur in the jdbc.custom.connection.properties file, so that they appear as follows:


# pega.jdbc.username db username
# pega.jdbc.password db password

[lines removed here]

# pega.jdbc.username=ADMIN
# pega.jdbc.password=ADMIN

 

2.  Set up your database to enable Kerberos functionality.  This may include additional vendor-specific JDBC driver configuration, or other setup procedures.  Check the documentation from your database vendor to determine what Kerberos setup is needed for your database.

 

3.  Run the command line installation or upgrade by following the instructions found in the Pega 7 Deployment guides.
