Tomcat log files moved to work directory

Valid from Pega Version 7.1.2

For Tomcat application server users, the default path for PRPC logs has been changed to the "work" directory for Catalina. For example:

<tomcat>\work\Catalina\localhost\prweb

This directory can be cleaned up during administration. To avoid loss of files, you can redirect logging to a different directory after installation:

  1. Navigate to the <tomcat-home>\webapps\prweb\WEB-INF\classes directory.
  2. Open the prlogging.xml file.
  3. Locate the "appender" definitions section that contains the "@{web.tmpdir}" string
  4. Update the FileNamePattern values to point to the new directory.

For more details, refer to the “Change the default path to PRPC logs” section in the Tomcat installation guide for your database.

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.

Split schema systems require additional privileges

Valid from Pega Version 7.1.2

On Oracle split schema systems, add the following database privileges:

  • Grant DROP ANY INDEX to the Admin User.
  • Grant UNLIMITED TABLESPACE to the Rules User.

Use the Oracle Enterprise Manager to add these privileges or refer to the 7.1.3 Upgrade and Installation guides for Oracle.

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.

Application overlays are enhanced to include more rules types that business users can change through the Decision Manager portal

Valid from Pega Version 7.1.7

Revision management overlays have been extended to include additional rule types (decision tree, and map value), enhancing the extent to which business users can review and change the logic used in strategies. For more information on this new feature, see the Revision Management landing page.

Direct deployment of decision parameters

Valid from Pega Version 7.1.7

Direct deployment overlays now enable business users to own decision parameters. Revisions based on this new type of overlay can be directly activated by Decision Manager portal users. For more information on this feature, see the Revision Management landing page.

Predictive Analytics Director portal

Valid from Pega Version 7.1.7

Predictive Analytics Director (PAD) has been integrated into Pega7, allowing you to develop and generate predictive models that can be used in strategies and process flows. The following new rulesets have been added to PegaDM to support this functionality: PredictiveAnalytics-IntSvcs, and PredictiveAnalytics-UI. For more information on rules using models generated by the Predictive Analytics Director portal, see About Predictive Model rules.

Third party models integration made possible by directly importing PMML in predictive models

Valid from Pega Version 7.1.7

Predictive models can now import models in PMML format. The PMML integration in predictive models allows you to use third party models without extra conversion and configuration. For more information on this new feature, see About Predictive Model rules.

Improved adaptive model accuracy

Valid from Pega Version 7.1.7

Enhancements have been made in the grouping scores method that is used to create the adaptive model outcome profile (also known as: classifier). Because scores form the base for calculating propensities, these changes make models more accurate. The enhanced grouping scores method is available with any new model generated in Pega 7.1.7 and does not require any changes to existing adaptive model rules or adaptive model components. For more information on adaptive models, see About Adaptive Model rules.

In-memory Adaptive Analytics Manager process

Valid from Pega Version 7.1.7

The new internal Adaptive Analytics Manager (ADM) process running in PRPC makes it possible to use adaptive analytics without the availability of the external ADM server. Although not a replacement for the external ADM server, it streamlines the design and development of applications making use of adaptive analytics. For more information on the configuration that allows your application to use the internal ADM process, see the Infrastructure Services landing page.
