Upgrading to the secure threading mechanism for email bots

Valid from Pega Version 8.1

In Pega Platform™ version 8.6, Pega Email Bot™ includes a more secure threading mechanism to help track emails from customers and other stakeholders in separate threads for an email triage case.

Upgrade impact

If you upgrade from Pega Platform version 8.5 or earlier, in which you configured an Email channel, perform the following steps to ensure that your system uses the new secure threading mechanism:

  • Update the service email rule that the system uses to send an email reply as the initial acknowledgment.
  • Update the email reply template in the data transform rule that the system uses when a customer service representative (CSR) sends the reply.

For more information about creating an initial acknowledgment email and email reply template, see Creating outbound email templates. For more information about the secure threading mechanism, see Use a secure threading mechanism in emails.

What steps are required to update the application to be compatible with this change?

For the initial acknowledgment email used by your email bot, update the service method for your email listener rule. On the Response tab for this service email rule, expand the Message contents section. In the Message data section, you specify the rule that defines the structure of the content of the email body. In Pega Platform version 8.6, you use for this purpose the pyEmailAcknowledgement correspondence rule that takes into account the selected built-in template. This template includes the security code tag that the system uses for the secure threading mechanism. If your application uses a different rule in the Message data section, update this definition to match one of the built-in correspondence template rules, for example, EmailAckTemplate_Clear.

The pySetEmailBotReplyTemplate data transform rule sets the name of the email correspondence rule that the system uses as the email reply template. If you do not want to use the default approach using the Classic, Cobalt, or Clear outbound email template themes, override this data transform rule to set the email correspondence rule name for the Param.ReplyTemplate target in the Source column field.

For more information about how to update the service email rule and the data transform rule to ensure that your system uses the secure threading mechanism, see Upgrading to the threading mechanism available in the 8.6 version.

Custom database (DB) triggers are dropped during upgrade

Valid from Pega Version 7.1.8

The latest version of Pega 7 improves performance by no longer using database triggers to assist with System Pulse and Data-Rule-Summary processing, which is now done within the Pega 7 engine. As a result, DB triggers are no longer installed on either the pr_sys_updatescache or pr4_rule_vw tables.

When upgrading to the latest version of Pega 7, if you had previously implemented a custom database (DB) trigger on these tables, or a custom DB trigger that refers to these tables, it is removed during the upgrade process. No custom triggers are removed unless they reference these tables.

If you have custom DB triggers that reference the pr_sys_updatescache or pr4_rule_vw tables and perform other processing, those triggers must be reimplemented. When doing so, you must be careful to not modify the pr_sys_updatescache or pr4_rule_vw tables.

For more information, see Startup check removes custom DB triggers.

End of support for Netscape Plugin API in Google Chrome 45

Valid from Pega Version 7.1.8

Beginning with Chrome 45, which is expected to be available in September 2015, Google is ending support for browser plug-ins that rely on the Netscape Plugin API (NPAPI) architecture. These plug-ins include Microsoft Silverlight, Adobe Flash Player, and Java.

The Pega 7 Platform includes several optional features that use these plug-ins. For a detailed overview of these features, see Client-side technologies.

Rules Assembly cache is deprecated

Valid from Pega Version 7.3.1

Rules Assembly (RA) cache and custom settings for its corresponding fua/assemblyCacheModeprconfig.xml file setting are deprecated because they are obsolete. A warning is logged at startup if a custom (non-default) value is specified for fua/assemblyCacheMode in the prconfig.xml file. The functional behavior of the system is not affected.

Use of PegaRULES_Extract_Marker.txt to delete cache is deprecated

Valid from Pega Version 7.3.1

The PegaRULES_Extract_Marker.txt file is deprecated. The system uses the presence or absence of the PegaRULES_Extract_Market.txt file to determine at startup whether to delete the static content, service export, and lookup list file system-based caches. In the rare situation that you need to delete these caches manually, use the System Management Application (SMA) ETier Static Content Management page. Using SMA does not require restarting the node.

Behavior changes when reporting on descendant classes

Valid from Pega Version 7.3.1

Report Definitions that use the Report on descendant class instances option with the Include all descendant classes option apply only to the Applies to Class. Join classes are not included as they were in previous Pega® Platform versions. The following example shows what happens for each possible scenario for Report on descendant class instances when the report is defined on ClassA with a class join with Work-.

  • If Report on descendant class instances is disabled, the report runs against ClassA and the join happens with Work-. The behavior is the same in Pega 7.3.1 as it is in previous Pega Platform versions.
  • If Report on descendant class instances is enabled, and Include single implementation class is selected, the report runs against ClassA and the join happens with the MySampleClass implementation class. The behavior is the same in Pega 7.3.1 as it is in previous Pega Platform versions.
  • If Report on descendant class instances is enabled, and Include all descendant classes is selected, the report runs against ClassA and its descendants and the join happens with Work-. In previous Pega Platform versions, the join happened with the MySampleClass implementation class.

Apache Ignite is no longer supported

Valid from Pega Version 8.1

Apache Ignite is no longer supported and has been replaced by Hazelcast Enterprise Edition 3.10 in embedded mode. If you used encryption with Apache Ignite, you can configure encryption on Hazelcast Enterprise Edition in the same way that you configured it for Apache Ignite.

For more information about encrypting nodes, see Enabling encrypted communication between nodes.

New roles required for system management features and APIs after upgrade

Valid from Pega Version 8.1

The pzSystemOperationsObserver and pzSystemOperationsAdministator privileges are no longer used for accessing system management features in Admin Studio and for system management APIs. Pega Platform™ has new privileges for individual system management functions and new roles configured with these privileges. Use the following roles to access system management features and APIs:

  • PegaRULES:SysOpsAdministrator – has all administrator and observer privileges
  • PegaRULES:SysOpsObserver – has all observer privileges
  • PegaRULES:SysAdm4 – has all administrator and observer privileges

After upgrading, you can include one or more of these roles in your access group or create a custom role. For more information about access roles, see Access roles.

Enabling access to upgraded help

After upgrading to Pega Platform ™ 8.1, the default URL to the upgraded help files might be incorrect. To enable access to the latest help files, reset the URL:

  1. In the header of Dev Studio, click Configure > System > Settings > URLs.
  2. Enter the Online Help URL:
    https://community.pega.com/sites/default/files/help_v81/
  3. Click Save.
