Derby databases are no longer supported
Valid from Pega Version 7.1.8
Previously, an embedded Derby database could be used as a file system. This setup was configured by setting storage/class/<<filesystem>>/type to "embedded" in the prconfig
file.
After upgrading, storage types that are specified as "embedded" now default to the local file system.
Custom database (DB) triggers are dropped during upgrade
Valid from Pega Version 7.1.8
The latest version of Pega 7 improves performance by no longer using database triggers to assist with System Pulse and Data-Rule-Summary processing, which is now done within the Pega 7 engine. As a result, DB triggers are no longer installed on either the pr_sys_updatescache
or pr4_rule_vw
tables.
When upgrading to the latest version of Pega 7, if you had previously implemented a custom database (DB) trigger on these tables, or a custom DB trigger that refers to these tables, it is removed during the upgrade process. No custom triggers are removed unless they reference these tables.
If you have custom DB triggers that reference the pr_sys_updatescache
or pr4_rule_vw
tables and perform other processing, those triggers must be reimplemented. When doing so, you must be careful to not modify the pr_sys_updatescache
or pr4_rule_vw tables
.
For more information, see Startup check removes custom DB triggers.

Configuration required for data operations on external schema when using a Postgres database
Valid from Pega Version 7.1.8
When you use the API for data operations on external schema in the Postgres database, you must update the prconfig.xml file. No other platform requires a prconfig.xml update.
To update the prconfig.xml file:
- Stop the server and add the following entry to the prconfig.xml file:
env name="database/databases/postgres_ext/defaultSchema"
value="externalschema"
wherepostgres_ext
is the external database that uses the external schema “externalschema”. - Restart the server.
End of support for Netscape Plugin API in Google Chrome 45
Valid from Pega Version 7.1.8
Beginning with Chrome 45, which is expected to be available in September 2015, Google is ending support for browser plug-ins that rely on the Netscape Plugin API (NPAPI) architecture. These plug-ins include Microsoft Silverlight, Adobe Flash Player, and Java.
The Pega 7 Platform includes several optional features that use these plug-ins. For a detailed overview of these features, see Client-side technologies.
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.
