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.
Customizations to the prlogging.xml file must be manually ported after upgrade
Valid from Pega Version 7.3
As a result of the upgrade from the Apache Log4j 1 logging service to the Apache Log4j 2 logging service, the name of the logging configuration file has changed from prlogging.xml to prlog4j2.xml and the format of the file has changed considerably. If you customized your prlogging.xml file, port the customizations to the new prlog4j2.xml file. If you do not port the changes, the Pega® Platform uses the default prlog4j2.xml file and disregards your customized prlogging.xml file.
For more information about customizing your log files, see the Apache Log4j 2 documentation.
Socket server has changed for remote logging
Valid from Pega Version 7.3
As a result of the upgrade from the Apache Log4j 1 logging service to the Apache Log4j 2 logging service, the socket server that is used for remote logging has changed from the Log4j remote logging package with the LogFactor5 log analysis tool to TcpSocketServer. If you use remote logging, update your socket server to TcpSocketServer. For more information, see Installing and using remote logging.
New process for Pega Cloud customers to obtain BIX extract files
Valid from Pega Version 7.3
The process for obtaining Business Intelligence Exchange (BIX) extract and manifest files for Pega® Cloud customers has changed as a result of data security enhancements for HIPAA compliance. By default, after upgrading to Pega 7.3, you must obtain the BIX extract and manifest files from the Pega SFTP server. From within Designer Studio, you can configure the BIX extract and manifest files to be sent to a remote SFTP server by a file listener. For Pega Cloud customers who have purchased a Pega Cloud SFTP Server subscription, you can configure BIX to send the BIX extract and manifest files to the SFTP server's folders for remote SFTP client download.
For more information about obtaining files from the Pega SFTP server, see Obtaining BIX extract files from the Pega SFTP server.
For more information about having files sent to your SFTP server, see Defining SFTP-related data instances.
Node types renamed after upgrade from Pega 7.2.2 to Pega Platform 7.3
Valid from Pega Version 7.3
If you used node classification in Pega® 7.2.2, when you upgrade to Pega 7.3, node type names are automatically changed to a new name when you start a node with a node type.
- UniversalNode becomes Universal
- WebUserNode becomes WebUser
- BackgroundProcessingNode becomes BackgroundProcessing
- BIXNode becomes BIX
- SearchNode becomes Search
If you created agents in Pega 7.2.2, agent schedules are also automatically updated with a new name during the upgrade. For more information, see Customized agent schedules for standard Pega Platform agents must be updated after Pega 7.2.2 to Pega Platform 7.3 upgrade and the appropriate Deployment Guide.
Requestor Management landing page access privileges
Valid from Pega Version 7.3
To access the Requestor Management landing page after upgrading to Pega® Platform 7.3, you need to add the appropriate privileges to the @baseclass and Pega-Landing access classes in the access roles. Apply these privileges to any application in which you want the operator to be able use the requestor management feature.
For more information, see the Requestor Management landing page and the appropriate Deployment Guide.
Rollover policy for log files
Valid from Pega Version 7.3
The rollover policy for log files is now based on time (daily) and file size (maximum file size is 250 MB). Log files are rolled over daily or when the maximum file size is reached. Current (not rolled over) log files do not have a time stamp. The time stamp is added when the log file is rolled over. In addition, the log file name for the current log file does not include the date. You can add the date to the current log file; however, the log file will not be rolled over. In addition, the web.temdir variable for setting the log file location is no longer supported; use the pega.logdir variable instead.
For more information, see Pega Platform logging with the Log4j 2 logging service.
Customized agent schedules for standard Pega Platform agents must be updated after Pega 7.2.2 to Pega Platform 7.3 upgrade
Valid from Pega Version 7.3
If you used node classification in Pega® 7.2.2, when you upgrade to Pega 7.3, node type names are automatically changed to a new name when you start a node with a node type. Agent schedules for standard Pega Platform agents are deleted and re-created with the new node type name, but any customization that you made in Pega 7.2.2 is not saved. You must manually update the agent schedules for standard Pega Platform agents in Pega 7.3.
For more information, see Node types renamed after upgrade from Pega 7.2.2 to Pega Platform 7.3 and the appropriate Deployment Guide.
