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.
Define custom dimensions in VBD data sets
Valid from Pega Version 7.3.1
Beginning with version 7.3.1, you can define custom dimensions when you create a Visual Business Director (VBD) data set in Pega® Platform. With this option, you can use any custom or existing property from the Applies To class of the VBD data set as a dimension to visualize your data, in addition to the properties in the default set of dimensions.
For more information, see Creating a Visual Business Director data set record.
Nodes in a cluster do not see each other for Docker, multiple VMs, or multiple NICs setup
Valid from Pega Version 7.3
If a cluster is set up in Docker, or uses separate virtual machines (VMs) or multiple network interfaces, you must set the public address in the prconfig.xml file for each Pega® Platform node to avoid problems with node clustering. Add the <env name=”identification/cluster/public/address” value=”IP address”/>
setting to specify the public address that is used by each node.
Extension attributes are not supported in PMML models
Valid from Pega Version 7.3.1
Models in the Predictive Model Markup Language (PMML) format version 4.3 that contain extension attributes with the x-
prefix are not valid. These extension attributes are deprecated; you must use extension elements instead. In addition, if the output type of any output field in the model is set to FLOAT
, change it to DOUBLE
.
For more information, see PMML 4.3 - General Structure in the Data Mining Group documentation.
The Upload responses action is not supported for adaptive models with customized context
Valid from Pega Version 7.3.1
A default instance of the Adaptive Model rule contains five model identifiers (.pyIssue, .pyGroup, .pyName, .pyDirection, .pyChannel) that are used to partition adaptive models. If you add other identifiers in your Adaptive Model rule instance, you cannot upload responses to this instance with the Upload Responses wizard and the following error is displayed: The Flow Action post-processing activity pzUploadCSVFile failed: Cannot parse csv file.
You can still train such adaptive models with data flows.
For more information, see Training adaptive models in bulk with data flows, Model context, and Uploading customer responses.
Decision Analytics portal renamed to Analytics Center
Valid from Pega Version 7.3.1
The Decision Analytics portal is renamed to the Analytics Center portal. In this work area for predictive analytics and text analytics, the business scientist can control the full model life cycle by building predictive models, importing PMML models, building sentiment analysis and text classification models, creating and monitoring adaptive models, and updating any existing models.
For more information, Analytics Center portal.
Extract data from Pega Cloud to an on-premises database
Valid from Pega Version 7.4
You can now use Pega® Business Intelligence Exchange (BIX) to extract data from Pega Cloud to an on-premises relational database management system. Extracting data from Pega Cloud directly to an on-premises database improves efficiency by eliminating the need for file extraction and the development of a file extraction infrastructure.
For more information, see Extracting data from Pega Cloud to an on-premises database.
Improved connection pooling performance
Valid from Pega Version 7.4
HikariCP is now used for connection pooling for databases that are configured by using a URL. HikariCP improves connection pooling performance; however, more database connections might be used than in previous versions of Pega® Platform.
As a result of the switch to HikariCP, you cannot use the System Management Application (SMA) to get diagnostic data from your application. For instructions about how to get diagnostic data by using REST services, see Obtaining connection pool diagnostic data by using REST services.
No longer supported translator configuration options
Valid from Pega Version 7.4
The following translator configuration options are not needed and are no longer supported. If you previously configured any of these system settings, remove them from the system settings to avoid a warning message. For example, if you set translator/useparserfamily, the following message is displayed at startup: "Translator option, 'translator/useparserfamily' is not needed and no longer supported. Remove this from the system settings."
- translator/useparserfamily
- translator/usecodegenerator
- translator/usenativedouble
- translator/optimization/use71BlockAnalysis
- translator/optimization/use71ConstantFolding
- translator/optimization/use71AssignmentTypeSimplification
- translator/optimization/use71IntrinsicFunctions
- translator/use71PropSetGeneration
- translator/use71ParserAssignment
- assembly/model/useBlock4ContiguousSets
- /translator/pandc/comparepandcalgorithms
- /translator/pandc/use6xalgorithms
- /Compatibility/CheckForTopLevelClassMismatch
In addition, the com.pega.pegarules.generation.parseoverride bootstrap option is no longer supported. Remove this option from the system settings.
New alert for distinct values query
Valid from Pega Version 7.3.1
The PEGA0093 alert identifies performance issues when a distinct values query from virtual reports or the getDistinctValuesForProperty
API take longer than the threshold. For more information, see PEGA0093: Distinct values query took more than the threshold.
