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.

Split schema upgrade instructions missing properties

Valid from Pega Version 7.1.3

If you upgraded from 5.x, 6.x, or 7.x using the instructions in previous versions of the upgrade guide, you may have neglected to set the properties below in your migrateSystem.properties file when you migrated your upgraded schema to the source system:

 

pega.rules.objects.generate=true

pega.rules.objects.apply=true

 

If these properties were not set during an upgrade that splits the schema, your environment does not have the indexes, triggers, and primary keys on the rules tables.

 

To check for this issue, see if the pr4_base and pr4_rule rules tables in your existing rules schema are missing primary keys. If they are, use the SQL scripts in the ResourceKit\MigrationRecoveryScripts directory of the release to cleanup duplicate rules that were created due to this issue. Follow the steps below to run the scripts.

To run the scripts on Microsoft SQL, Oracle, or PostgreSLQ

  1. Take down any app servers using the affected schema.
  2. Backup your database.
  3. Replace all instances of @RULES_SCHEMA in <database>_cleanDups.sql with the name of the schema that contains the pr4_base table.
  4. Run the <database>_cleanDups.sql script on the database with vendor tools (sqlPlus, SQL Server Management Studio, etc).
  5. Replace all instances of @RULES_SCHEMA in <database>_fix_vw_table.sql with the name of the schema that contains the pr4_base table.
  6. Run the <database>_fix_vw_table.sql script on the database with vendor tools (sqlPlus, SQL Server Management Studio, etc).
  7. Generate and apply the ddl using the command line generateDDL command. Check the installation guide for your database or the upgrade guide for details about how to use the generateDDL command line script.
  8. Rebuild the indexes for the tables in your rules schema using vendor tools. This is necessary so that your system runs at an optimum speed.
  9. Optionally upgrade to the latest release, at this point your database is ready to be upgraded or used depending on your needs.

      

To run the scripts on DB2 for LUW or z/OS

  1. Take down any app servers using the affected schema.
  2. Backup your database.
  3. Run the <database>_cleanDups.sql script on the database with vendor tools (UDB CLP, Data Studio, etc) to create the CLEANSE_RULES_DUPS stored procedure.
  4. Run the query Call CLEANSE_RULES_DUPS(‘<rulesSchema>’); where <rulesSchema> is the name of schema that contains the pr4_base table.
  5. After the previous step is complete drop the CLEANSE_RULES_DUPS procedure.
  6. Replace all instances of @RULES_SCHEMA in <database>_fix_vw_table.sql with the name of the schema that contains the pr4_base table.
  7. Run the <database>_fix_vw_table.sql script on the database with vendor tools (UDB CLP, Data Studio, etc).
  8. Generate and apply the ddl using the command line generateDDL command. Check the installation guide for your database or the upgrade guide for details about how to use the generateDDL command line script.
  9. Rebuild the indexes for the tables in your rules schema using vendor tools. This is necessary so that your system runs at an optimum speed.
  10. Optionally upgrade to the latest release. At this point your database is ready to be upgraded or used depending on your needs.

Data schema error on z/OS split schema upgrades from versions before Pega 7.1.8

Valid from Pega Version 4.1

When upgrading to a split schema on Pega 7.x with IBM DB2 for z/OS, you see an error during the data schema upgrade when the system tries to drop the PRPC_Updatescache procedure. Because triggers on rules tables use PRPC_Updatescache, you must use the ZOSDisableTriggerScripts to disable these triggers before you update the data schema.

  1. Follow the instructions in the Pega 7 Platform Upgrade Guide to upgrade the rules schema, but stop immediately before you upgrade the data schema with the upgrade.bat or upgrade.sh script. The Pega 7 Platform Upgrade Guide is on the Support > Deployment Guides page.
  2. Copy the contents of the <distribution>\ResourceKit\ZOSDisableTriggerScripts directory into the <distribution>\scripts\ directory.
  3. Run fixZosTriggers.bat or fixZosTriggers.sh with the following arguments:
    --action preupgrade
    --dataschema <data schema name>
    --oldrulesschema <old rules schema name. If you are upgrading from a single-schema system, this is the data schema name.>
    --newrulesschema <new rules schema name>
    --automaticddl <Optional. Set to true to automatically apply the disable trigger SQL scripts.>

    For example:
    fixZosTriggers --action preupgrade --dataschema pegadata --oldrulesschema pegarules --newrulesschema newrules --automaticddl false

  4. If you did not set --automaticddl to true in the previous step, run the <distribution>\schema/disable.sql script to manually disable the trigger SQL scripts.
  5. Run the data schema upgrade as described in the Pega 7 Platform Upgrade Guide.

Update Existing Applications wizard will run for every upgrade

Valid from Pega Version 7.1.7

The upgrade process from a PRPC 5.x or 6.x system to Pega 7.1.7 now automatically runs the Update Existing Applications wizard. This may extend the time that the upgrade process takes to complete, depending on the version you are upgrading from and the number of rules in your application.

Upgrading to Pega 7.1.7 with an Oracle database requires new role permissions

Valid from Pega Version 7.1.7

When upgrading or updating from a prior version to Pega 7.1.7, if your system uses an Oracle database, an additional role is required to support the Reversability functionality. In addition to the Oracle privileges specified in the Install Guides, the role SELECT_CATALOG_ROLE is required. Verify that this role is present before beginning the upgrade or update.

Action required by admins for improved search

Valid from Pega Version 7.1.7

Starting November 13, 2014, after updating to or upgrading from a prior version to Pega 7.1.7, your system administrator must manually build all indexes for Elasticsearch before the system can automatically switch from Lucene to Elasticsearch.

It is recommended that you begin this manual re-indexing process for all enabled index types as soon as your update or upgrade is complete. The search landing page refers to Elasticsearch settings; during re-indexing, however, Lucene search continues to function to ensure that there is no interruption in search functions. When planning the re-indexing, be aware that the initial re-indexing requires significant resources on the host node and can be a lengthy process, depending on the number of rules and work objects in your system.

See the Pega 7.1.7 Upgrade Guide for information about manually indexing Elasticsearch.

Updates no longer require redeploying the prweb.war file or the application server-specific EAR file

Valid from Pega Version 7.1.7

Updating from Pega 7.1.7 to later versions of Pega 7 no longer requires that you redeploy the prweb.war file or the application server-specific EAR file.

Note that upgrades from versions prior to Pega 7.1.7 still require that you redeploy these files.

Service responses in HTTP and REST connectors are no longer modified

Valid from Pega Version 7.1.7

The Pega 7.1.8 release correctly leaves form service responses for HTTP and REST connectors unmodified. Upgrade to this release if you experience a problem in Pega 7.1.7 where service responses for HTTP and REST connectors are modified when the declared type in the Content-Type header is application/x-www-form-urlencoded. In this case, the responses were modified to a base 64 representation of the bytes in the string. In Pega 7.1.8, responses of type application/x-www-form-urlencoded are mapped to the property designated on the Connector record.
