DB2-LUW database logfile size increase
Valid from Pega Version 7.1.5
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
Valid from Pega Version 7.1.5
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.

Unused agents run in background
Valid from Pega Version 7.2
The Update PegaRULES database table statistics agent and the Collect PegaRULES database blob size statistics agent have been added to support future development. These agents run in the background, but they do not do anything. You can, but do not need to, disable them from the Edit Agent Schedule landing page.
