Published Release Notes

DB2-LUW database logfile size increase

To avoid running out of logfile space due to large transaction sets during the rule base load of a Pega 7.1.x install, upgrade, or maintenance level update, systems supported by a DB2-LUW database platform should increase the LOGFILSIZ parameter to at least 4096 pages from the default size of 1000 pages.

After the size has been increased, restart the database to ensure that the new setting is loaded into the database correctly.

Existing collections are deprecated

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.

Need to run script before updating Multitenant systems

When updating or upgrading a Multitenant system from Pega 7.1.5 or 7.1.6 to Pega 7.1.7, if that system uses either an Oracle or a PostgreSQL database, you may encounter the error:

“Table must be empty to add column.”

The Multitenant architecture requires an additional column on a number of the PRPC database tables (“pzTenantID”). In Pega 7.1.7, two additional PRPC tables were tenant-qualified: pc_schedule_task and pr_index_schedule_task. The Multitenant column is added to these tables by the update/upgrade process. However, Oracle and PostgreSQL do not allow the addition of a non-null column to an existing table unless the table is empty, so updating or upgrading systems on those databases displays the error detailed above.

To avoid this error, before beginning the update or upgrade, it is necessary to run a script:

• Oracle — OracleMTupgrade.sql
• PostgreSQL — PostgresMTupgrade.sql

For updates, these scripts are located in the /scripts/ddl directory.

For upgrades, these scripts are located in the /Resourcekit/AdditionalUpgradeScripts directory.

Messages are rule resolved by class

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

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.

Changes to archive.info in Pega 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

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.

Service responses in HTTP and REST connectors are no longer modified

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.
