Deprecation of EAR deployments in Pega Platform 8.6

Valid from Pega Version 8.6

Starting with Pega Platform 8.6, EAR deployments of Pega Platform are deprecated. In the upcoming 8.7 release, EAR deployments will not be supported. The following rules that require EAR deployments will also be deprecated and no longer supported in Pega Platform 8.7:

  • Connect EJB
  • Connect JCA
  • JCA Resource Adapter
  • JMS MDB Listener
  • Service EJB

With this deprecation, you can use the latest tools and keep your application up to date. 

Upgrade impact

In Pega Platform 8.6, you can still create rules that require EAR deployments and update existing rules. However, after an upgrade to Pega Platform 8.7, rules that require EAR deployments are no longer supported.

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

To prepare your application for this change well in advance of the Pega Platform 8.7 release, see the following table for a list of alternative rules and for guidance on modernizing your application.

Deprecated rule typeAlternative rule typeRecommended configuration
Connect EJBConnect RESTSubstitute legacy EJB resources with a REST API, and use REST connectors to interact with them.
Connect JCAConnect RESTSubstitute legacy JCA resources with a REST API, and use REST connectors to interact with them.
JCA Resource AdapterJCA resource adapters are data records that are used within the scope of a Connect JCA rule. If you replaced Connect JCA rules in your application with Connect REST rules, JCA resource adapters are no longer relevant.No further configuration is necessary.
JMS MDB ListenerJMS ListenerReplace JMS MDB Listener configurations with standard JMS Listener configurations.
Service EJBService RESTRedefine your EJB services as a set of RESTful service APIs, and invoke them over HTTP/HTTPS.

For information on the supported platforms that are affected by this deprecation, see Pega Platform 8.6 Support Guide.

Legacy Parse XML rule configurations must be upgraded to edit them

Valid from Pega Version 8.6

If your application has Parse XML rules that use the legacy configuration from Pega Platform 5.x, you cannot edit these rules after you upgrade to Pega Platform 8.6 until after you upgrade them to use tree-based parse rule configuration.

You must upgrade a Parse XML rule that you want to edit if it shows the following warning when you open it in Dev Studio.

This type of Parse XML rule is deprecated. An upgrade should be performed.

An option to upgrade also displays below the message.

Upgrade impact

Parse XML rules with the legacy configuration do not map data to the clipboard, and the rule definition is empty. After you upgrade to Pega Platform 8.6, you cannot edit Parse XML rules that you created in Pega Platform 5.x or earlier until you upgrade them to use tree-based parse rule configuration.

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

Update legacy Parse XML rules to use tree-based parse rule configuration before you edit them in Pega Platform 8.6. Using tree-based parse rules is considered a best practice.

  1. Open the legacy Parse XML rule.
  2. On the Mapping tab, click Upgrade.
    Result: The Allow tree editing? check box is displayed and is automatically selected. You can add attributes and elements to the tree structure, or delete them.
  3. Save the upgraded rule configuration.

For more information, see Parse XML rules.

Connect MQ rules configured with alias queue do not work after upgrade

Valid from Pega Version 8.6

Connect MQ rules that you defined with an alias queue in earlier versions of Pega Platform do not work after an upgrade to Pega Platform 8.6.

Upgrade impact

If you defined an alias queue in Connect MQ rules, after an upgrade to Pega Platform 8.6, those Connect MQ rules do not work.

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

In the Pega-IntegrationEngine ruleset, create the following dynamic system settings and their default values:

  • "mq/pmo" = 0
  • "mq/gmo" = 0
  • "mq/oo_request" = 1040
  • "mq/oo_response" = 16

For more information, see Creating a dynamic system setting.

Data Management

Valid from Pega Version 7.1.3

Improvements to data handling were made for the Data Pages, autopopulate properties, and reference properties.  Lightweight lists were optimized.

  • Property references are now maintained on the Work Page.
  • PageList properties can reference a Data Page.
  • Auto-populate properties can be used in a seciton to show results from a Data Page.
  • Data Pages can run in “Page” mode as well as “List” mode
  • The "Rules Not Using Lightweight List" report was enhanced.
  • A PageList property that references a Data Page may be used to populate a grid.
  • Related autopopulated properties can now be referenced.

Integration

Valid from Pega Version 7.1.3

Usability enhancements have been made to the integration wizards. The REST end-point integration has been improved, and XML parsing functionality has been enhanced.

  • PRPC services can return Report or Listview data as XML.
  • Work items may now be processed when accessing from a link in system-created emails.
  • An SMTP outage will not cause an application to stop working.
  • File listener will now read files using a leading asterisk (*).
  • XML Parse rule will handle schema validation.
  • PegaImageViewer will now work with Version 7.1.
  • Security measures are enhanced for SOAP connections to web services.
  • After generating rules using REST wizard, the Undo Generation button will delete all the generated rules.
  • Email wizard has been improved.

Derby databases are no longer supported

Valid from Pega Version 7.1.8

Previously, an embedded Derby database could be used as a file system. This setup was configured by setting storage/class/<<filesystem>>/type to "embedded" in the prconfig file.

After upgrading, storage types that are specified as "embedded" now default to the local file system.

Configuration required for data operations on external schema when using a Postgres database

Valid from Pega Version 7.1.8

When you use the API for data operations on external schema in the Postgres database, you must update the prconfig.xml file. No other platform requires a prconfig.xml update.

To update the prconfig.xml file:

  1. Stop the server and add the following entry to the prconfig.xml file:
    env name="database/databases/postgres_ext/defaultSchema"
    value="externalschema"
    where postgres_ext is the external database that uses the external schema “externalschema”.
  2. Restart the server.
