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
- Take down any app servers using the affected schema.
- Backup your database.
- Replace all instances of @RULES_SCHEMA in <database>_cleanDups.sql with the name of the schema that contains the pr4_base table.
- Run the <database>_cleanDups.sql script on the database with vendor tools (sqlPlus, SQL Server Management Studio, etc).
- Replace all instances of @RULES_SCHEMA in <database>_fix_vw_table.sql with the name of the schema that contains the pr4_base table.
- Run the <database>_fix_vw_table.sql script on the database with vendor tools (sqlPlus, SQL Server Management Studio, etc).
- 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.
- 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.
- 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
- Take down any app servers using the affected schema.
- Backup your database.
- 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.
- Run the query Call CLEANSE_RULES_DUPS(‘<rulesSchema>’); where <rulesSchema> is the name of schema that contains the pr4_base table.
- After the previous step is complete drop the CLEANSE_RULES_DUPS procedure.
- Replace all instances of @RULES_SCHEMA in <database>_fix_vw_table.sql with the name of the schema that contains the pr4_base table.
- Run the <database>_fix_vw_table.sql script on the database with vendor tools (UDB CLP, Data Studio, etc).
- 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.
- 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.
- Optionally upgrade to the latest release. At this point your database is ready to be upgraded or used depending on your needs.
Existing collections are deprecated
Valid from Pega Version 7.1.7
The original implementation of the Collection form is deprecated. Legacy instances in your application remain functional; however, any new instance you create uses the redesigned Collection form. Use the Decision category in the Records Explorer to view all collections available to you.
For guidance on upgrade limitations, see the Deprecated Collection form.
Messages are rule resolved by class
Valid from Pega Version 7.1.7
As part of the Message form redesign, a class key part was introduced. While this key part is automatically handled as part of an upgrade or migration, it does change the available options you see in message SmartPrompts and how Rule-Message instances are rule resolved.
See Upgrade considerations for existing messages for more information.
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.
Changes to archive.info in Pega 7.1.7
Valid from Pega Version 7.1.7
In Pega 7.1.7, the contents of the archive.info file have changed.
- In versions Pega 7.1.6 and earlier, the archive.info file displays the build number of the Pega installation.
- As of Pega 7.1.7, the build number no longer appears in the archive.info file.
In Pega 7.1.7, the archive.info file only displays a status message indicating whether or not the system is running, and the build number no longer appears. Instead, if the system is operational, the message “status=Running” displays in the archive.info file.
If there are any automated tests, scripts, or applications that rely on the archive.info file displaying the build number, those may fail and produce an error. It is recommended that any automation that relies on the build number displaying in the archive.info file be changed to look for the “status=Running” message.
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.
Updated Word merge support with Microsoft Silverlight plug-in
Valid from Pega Version 7.1.3
Starting in this release, Pega 7 features that integrate with the Word merge capability are now cross-browser. ActiveX controls (which are only compatible with Internet Explorer) have been replaced with Microsoft Silverlight. This plug-in must be downloaded separately from Microsoft because it is not shipped with Pega 7.
Common features that are affected by this change include the Specification form and Case Type landing page.
Prior to using these features, see the release note Word merge support with Microsoft Silverlight plug-in for more information about setting up their client systems.
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.
