Published Release Notes

EAR support for JBoss EAP 6

PRPC deployment in JBoss EAP 6 as an EAR archive is now supported. 

If you need to deploy the JBoss EAR file, go to My Support Portal and submit a Support Request. GCS can assist you with the procedure.

Small distribution kit

A new “small” release distribution format for Maintenance Levels (ML) is now available, designed to significantly increase adoption via: 

• Minimal package size and faster download time
• Minimal install time via tactical changes to the upgrade implementation and process

This kit contains streamlined installers (both UI and command-line installers) and specialized error handling for ML updates (for example, a “small” kit will only work if an existing version of the same release is already installed). 

The kit assembly has also been automated, which includes the construction of a PRPC_Rules.jar archive containing cumulative rules since the GA release. 

A “small” kit will work for any prior ML release within a major release (for example, the “small” ML5 distribution kit will update any customer on 7.1 ML1 through 7.1 ML4).

Improved data page performance

Improvements have been made with queueing and processing of asynchronously-loaded data pages to reduce the number of calls to the database and avoid generating performance problems because of unneeded asynchronous requests.

Restricted SMA access

System Management Application (SMA) remote connections are not supported on JBoss EAP 6.x. This means SMA users may only monitor locally connected systems. Ensure that the "Local JVM Connection..." option is selected when configuring PRPC nodes:

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.

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.

End of support for Microsoft Internet Explorer 9 in Pega 7.2.1

In accordance with Microsoft’s announcement to discontinue support for Internet Explorer 9, Pega 7.2.1 will not support Internet Explorer 9. You should not upgrade to Pega 7.2.1 if you are still using Internet Explorer 9. Otherwise, upgrade to Microsoft Internet Explorer 10 or later, or use Google Chrome, Apple Safari, or Mozilla Firefox, which support certain HTML5 and CSS3 standards not supported in Internet Explorer 9.

For more information about browser support, see the Platform Support Guide or contact Pegasystems Global Customer Support.

Ability to import data into a Pega Cloud database

You can export a custom Pega 7 Platform database table into a CSV file and import it into a Pega Cloud database or other Pega 7 Platform database by using the Data Upload utility. This utility is available only for Postgres databases and tables that do not contain BLOB columns. This utility is useful, for example, for updating a product catalog that is used in a Pega Cloud application.

For more information, see Importing data into a Pega Cloud database.

Ability to schedule schema updates for Pega Cloud

You can schedule BLOB size and table statistic updates to database schemas to run automatically by using agents. Scheduling schema updates is useful for performance monitoring and tuning in the Pega Cloud. This feature is available only for customers who use a Postgres database.

There is an agent for updating the average and maximum BLOB sizes, and an agent for updating table statistics. Each agent can be configured separately for each schema. You can configure whether to schedule the agent to run daily or weekly. You can deactivate a running schedule on the Schema Tools landing page by clicking Designer Studio > System > Database > Schema Tools. From the Schema Tools landing page, you can configure more complex scheduling on the Edit Agent Schedule landing page. In addition, you can configure these agents by using Dynamic Data System Settings.

For more information, see Scheduling schema updates.

Immediate drain available for the quiesce process when using high availability

The quiesce process, which is used to take a server out of service for maintenance in a highly available system, can now be modified to use the immediate drain method. When using the default slow drain method for quiesce, users are placed in a passivation queue. When using the immediate drain method, users can continue to access the node being quiesced until it is removed from the load balancer.

Organizations should determine which quiesce method to use based on the overall needs of their users. However, for applications that have implemented long poll requests, it is recommended to use the slow drain method.

For more information, see the Pega 7.2.1 High Availability Administration Guide.
