Published Release Notes

Split schema upgrade instructions missing properties

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.

Update Existing Applications wizard will run for every upgrade

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

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

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

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.

Agents not running after update of EAR-based deployment

If you update an EAR-file deployment and your update meets both of the following criteria, you must redeploy the prpc_*.ear file for your application server after you complete the update to avoid agent-related errors:

• Updating from Pega 7.1.7, Pega 7.1.8, or Pega 7.1.9
• Updating to Pega 7.1.10, 7.1.11, 7.2, or 7.2.1

If you do not redeploy the prpc_*.ear file, you will see the agent-related issues that are described in the support article Agents are not running.

For information about redeploying, see the Pega 7 Platform Update Guide for your target version of the Pega 7 Platform.

Node types renamed after upgrade from Pega 7.2.2 to Pega Platform 7.3

If you used node classification in Pega^® 7.2.2, when you upgrade to Pega 7.3, node type names are automatically changed to a new name when you start a node with a node type.

• UniversalNode becomes Universal
• WebUserNode becomes WebUser
• BackgroundProcessingNode becomes BackgroundProcessing
• BIXNode becomes BIX
• SearchNode becomes Search

If you created agents in Pega 7.2.2, agent schedules are also automatically updated with a new name during the upgrade. For more information, see Customized agent schedules for standard Pega Platform agents must be updated after Pega 7.2.2 to Pega Platform 7.3 upgrade and the appropriate Deployment Guide.

Rollover policy for log files

The rollover policy for log files is now based on time (daily) and file size (maximum file size is 250 MB). Log files are rolled over daily or when the maximum file size is reached. Current (not rolled over) log files do not have a time stamp. The time stamp is added when the log file is rolled over. In addition, the log file name for the current log file does not include the date. You can add the date to the current log file; however, the log file will not be rolled over. In addition, the web.temdir variable for setting the log file location is no longer supported; use the pega.logdir variable instead.

For more information, see Pega Platform logging with the Log4j 2 logging service.

Customized agent schedules for standard Pega Platform agents must be updated after Pega 7.2.2 to Pega Platform 7.3 upgrade

If you used node classification in Pega^® 7.2.2, when you upgrade to Pega 7.3, node type names are automatically changed to a new name when you start a node with a node type. Agent schedules for standard Pega Platform agents are deleted and re-created with the new node type name, but any customization that you made in Pega 7.2.2 is not saved. You must manually update the agent schedules for standard Pega Platform agents in Pega 7.3.

For more information, see Node types renamed after upgrade from Pega 7.2.2 to Pega Platform 7.3 and the appropriate Deployment Guide.
