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.

Cannot copy final section rules in UI Kit ruleset

Valid from Pega Version 7.1.6

You cannot copy section rules in the UI Kit ruleset (UI-Kit-71) that start with pz or px (final rules in the base PRPC rulesets).

Instead, to customize these rules, use the Copy/Merge Ruleset tool, available at Designer Studio >System > Tools > Refactor Rulesets, to copy all rules from the UI Kit into your application ruleset. You can then check the section rules in and out.

User interface distortions in the Decision Manager portal

Valid from Pega Version 7.1.6

By default, the New Application wizard in Pega 7.1.6 configures new applications to include UI-Kit-7 in the list of application rulesets. This ruleset causes user interface distortions in the Decision Manager portal. Both applications created in previous maintenance level updates and applications created in Pega 7.1.6 that do not include the UI-Kit-7 dependency are not impacted by this known issue.

Workaround:

  1. Open the application record.
  2. In Application Rulesets, remove UI-Kit-7.
  3. Save the application record.

User interface distortions in the Predictive Analytics Director portal

Valid from Pega Version 7.1.6

By default, the New Application wizard configures new applications to include UI-Kit-7 in the list of application rulesets. This ruleset causes user interface distortions in the Predictive Analytics Director portal. Applications created in maintenance level updates previous to Pega 7.1.6, and applications that do not include the UI-Kit-7 dependency, are not impacted by this known issue.

Workaround:

  1. Open the application record.
  2. In Application Rulesets, remove UI-Kit-7.
  3. Save the application record.

Microsof Internet Explorer 9 (IE9) may display a script error when clicking a Help button

Valid from Pega Version 7.1.6

A script error may be displayed when clicking a Help button when script error notification is turned on in the browser. As a work around, uncheck the Display a notification about every script error option in the Advanced tab of the Options dialog box in Microsoft Internet Explorer 9.

System starts slowly after upgrade or update on IBM DB2 for z/OS

Valid from Pega Version 7.2.2

Additional tables are added to upgraded and updated systems. If your system starts up very slowly after an upgrade or update, the database statistics on these new tables might not have generated correctly. To correct this issue and improve performance, your database administrator needs to manually rebuild the statistics for all tables in the rules schema.

Clustering equal to none might cause errors

Valid from Pega Version 7.2.2

Some Pega 7 Platform features might not work when theidentification/cluster/protocolsetting in the prconfig.xml file is set to none. Some features that might not work are remote tracing and management actions on the node from the Requestor Management and Agent Management landing pages. Setting the clustering protocol to none is not recommended and will not be supported in a future Pega 7 Platform release.

Disregard this startup error for Oracle Weblogic deployments

Valid from Pega Version 7.2.2

If you install, upgrade, or update your Oracle Weblogic application server to Pega 7.2.2, disregard the error stack that begins with text similar to the following:

ERROR - WebLogic Server 12.1.3.0.0 Wed May 21 18:53:34 PDT 2014 1604337 Oracle WebLogic Server Module Dependencies 12.1 Tue Mar 11 15:35:15 MDT 2014 WebLogic Jersey Server Integration 3.0 Fri Feb 21 10:55:11 UTC 2014 must use JDK 1.8+ with WebSocket
2016-11-07 06:13:01,690 [ WIN-L3EEURCNCP1] [ STANDARD] (pr.DefaultAsyncSupportResolver) ERROR - Real error: Unable to configure jsr356 at that stage. ServerContainer is null

This message appears because the Pega 7.2.2 real-time notification feature initially tries to use WebSocket and then falls back to long polling. The Pega 7 Platform does not support WebSocket for Oracle Weblogic servers, and instead uses long polling for real-time notifications.
