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.

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.

Existing operator IDs during upgrades and updates

Upgrades and updates are always performed in secured mode to help prevent unauthorized access to your system. In secured mode, the administrator@pega.com operator ID is always overwritten, but other existing standard operator IDs are not modified. New operator IDs are inserted in secured mode. For more information, see the Deployment Guide for your environment.

BIX -I command-line option fails for unexposed properties

Business Intelligence Exchange (BIX) command-line extractions fail when the extract has a filter that uses unexposed property references that are passed in by the input file that you specified in the -I command-line option. Previously, the BIX extraction ignored the filter and the extraction did not fail.

Apache Ignite is no longer supported

Apache Ignite is no longer supported and has been replaced by Hazelcast Enterprise Edition 3.10 in embedded mode. If you used encryption with Apache Ignite, you can configure encryption on Hazelcast Enterprise Edition in the same way that you configured it for Apache Ignite.

For more information about encrypting nodes, see Enabling encrypted communication between nodes.

New roles required for system management features and APIs after upgrade

The pzSystemOperationsObserver and pzSystemOperationsAdministator privileges are no longer used for accessing system management features in Admin Studio and for system management APIs. Pega Platform™ has new privileges for individual system management functions and new roles configured with these privileges. Use the following roles to access system management features and APIs:

• PegaRULES:SysOpsAdministrator – has all administrator and observer privileges
• PegaRULES:SysOpsObserver – has all observer privileges
• PegaRULES:SysAdm4 – has all administrator and observer privileges

After upgrading, you can include one or more of these roles in your access group or create a custom role. For more information about access roles, see Access roles.

Enabling access to upgraded help

1. In the header of Dev Studio, click Configure > System > Settings > URLs.
2. Enter the Online Help URL:

   https://community.pega.com/sites/default/files/help_v81/

3. Click Save.
