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.
Locatable pages are deprecated
Valid from Pega Version 7.3.1
Locatable pages are deprecated. Use a data page instead. Data pages provide improved performance. When you save a rule that has a Locate Page Activity or when you create an activity of type Locate page, a guardrail warning is displayed indicating that this feature has been deprecated.
For information about data pages, see Data pages.
Rules Assembly cache is deprecated
Valid from Pega Version 7.3.1
Rules Assembly (RA) cache and custom settings for its corresponding fua/assemblyCacheMode
prconfig.xml file setting are deprecated because they are obsolete. A warning is logged at startup if a custom (non-default) value is specified for fua/assemblyCacheMode
in the prconfig.xml file. The functional behavior of the system is not affected.
Use of the @java function in expressions is deprecated
Valid from Pega Version 7.3.1
Use of the @java function in expressions is deprecated. Use a utility function or other product feature instead.
For more information about expressions, see Building expressions with the Expression Builder.
Interactions in flows are no longer supported by the Run Interaction shape
Valid from Pega Version 7.3.1
The Run Interaction shape in flows has been replaced by the Run Data Flow shape, which supports running a single case data flow with a strategy. Flows that include the Run Interaction shape continue to work; however, you must now use the Utility shape to reference any new interactions that you create.
For more information, see Running a decision strategy from a flow and About Interaction rules.
Use of PegaRULES_Extract_Marker.txt to delete cache is deprecated
Valid from Pega Version 7.3.1
The PegaRULES_Extract_Marker.txt file is deprecated. The system uses the presence or absence of the PegaRULES_Extract_Market.txt file to determine at startup whether to delete the static content, service export, and lookup list file system-based caches. In the rare situation that you need to delete these caches manually, use the System Management Application (SMA) ETier Static Content Management page. Using SMA does not require restarting the node.
Behavior changes when reporting on descendant classes
Valid from Pega Version 7.3.1
Report Definitions that use the Report on descendant class instances option with the Include all descendant classes option apply only to the Applies to Class. Join classes are not included as they were in previous Pega® Platform versions. The following example shows what happens for each possible scenario for Report on descendant class instances when the report is defined on ClassA with a class join with Work-.
- If Report on descendant class instances is disabled, the report runs against ClassA and the join happens with Work-. The behavior is the same in Pega 7.3.1 as it is in previous Pega Platform versions.
- If Report on descendant class instances is enabled, and Include single implementation class is selected, the report runs against ClassA and the join happens with the MySampleClass implementation class. The behavior is the same in Pega 7.3.1 as it is in previous Pega Platform versions.
- If Report on descendant class instances is enabled, and Include all descendant classes is selected, the report runs against ClassA and its descendants and the join happens with Work-. In previous Pega Platform versions, the join happened with the MySampleClass implementation class.
Service Portlet rules are deprecated
Valid from Pega Version 8.2
Service Portlet rules are deprecated. Existing rules will continue to work, but you cannot create new ones. Use Pega Web Mashup instead. In addition, some changes might impact functionality. If you are using Portlet rules and plan to upgrade, contact your customer service representative.
For more information about Pega Web Mashup, see About Pega Web Mashup.
Deprecated metadata types in the Connector and Metadata wizard
Valid from Pega Version 8.2
The WSDL, SAP WSDL, and DTD metadata types have been deprecated in the Connector and Metadata wizard. For WSDL, use SOAP integration, and for DTD, use XSD.
For more information about SOAP connectors, see About Connect SOAP rules. For more information about XSD, see About the Connector and Metadata wizard.
