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.

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.

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.

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". 

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:

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.

When using Oracle 12.1.0.1, left outer joins in reports may return incorrect results

Valid from Pega Version 7.1.1

When using  Pega 7 with Oracle 12.1.0.1 , reports that use left outer joins may return incorrect results.

This is an Oracle known issue.  To resolve this behavior, upgrade to Oracle 12.1.0.2, apply the Oracle patch 16726638 by requesting it directly from Oracle, or, for Microsoft Windows installations, apply Windows Bundle patch 12.1.0.1.15 or later.

For more information in this behavior, see: https://support.oracle.com/epmos/faces/DocumentDisplay?_afrLoop=392085808201943&id=1957943.1

Column Populator utility documentation out of date for prior versions

Valid from Pega Version 7.2

The documentation for using the Column Populator utility to populate newly exposed database columns is out of date for Pega 7 Platform versions prior to 7.2. For all Pega 7 versions, refer to the Pega 7.2 help documentation for instructions about how to use this utility.

Child case queries performance can be slow

Valid from Pega Version 7.2

Some customers have reported that performance is slow when they execute queries on child cases. This issue is often indicated by PEGA0005 (query time exceeded limit) alerts that can be correlated to these queries in the logs. To resolve the issue, add a database index to each of your work tables by using a multicolumn index on the pxCoverInsKey, pxObjClass, and pyStatusWork columns.
