Tomcat log files moved to work directory
Valid from Pega Version 7.1.2
For Tomcat application server users, the default path for PRPC logs has been changed to the "work" directory for Catalina. For example:
<tomcat>\work\Catalina\localhost\prweb
This directory can be cleaned up during administration. To avoid loss of files, you can redirect logging to a different directory after installation:
- Navigate to the <tomcat-home>\webapps\prweb\WEB-INF\classes directory.
- Open the prlogging.xml file.
- Locate the "appender" definitions section that contains the "@{web.tmpdir}" string
- Update the FileNamePattern values to point to the new directory.
For more details, refer to the “Change the default path to PRPC logs” section in the Tomcat installation guide for your database.
Slow WebSphere performance on Mac platforms
Valid from Pega Version 7.1.2
Use the following JVM setting to improve WebSphere performance on Mac platforms:
-Djava.net.preferIPv4Stack=true
Split schema systems require additional privileges
Valid from Pega Version 7.1.2
On Oracle split schema systems, add the following database privileges:
- Grant DROP ANY INDEX to the Admin User.
- Grant UNLIMITED TABLESPACE to the Rules User.
Use the Oracle Enterprise Manager to add these privileges or refer to the 7.1.3 Upgrade and Installation guides for Oracle.
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.
Convert data instances into decision parameter rules
Valid from Pega Version 7.1.8
The Convert groups wizard is available in the Hierarchy landing page when the list of your propositions include decision data records.
Click Convert groups at the top of the landing page to use the wizard and to convert data instances into decision parameter rules. This conversion is necessary to make the existing proposition data instances available for revision management.
Update to the Data Flows rule
Valid from Pega Version 7.1.8
It is now possible to collect statistics for each active data flow. These include the number of processed records, records that caused errors and last processed records per shape, as well as historical throughput measured for the entire data flow.
There are two new patterns in the Data Flow rule:
- Event Strategy - define this pattern to use an event strategy in a data flow and to connect a data stream and static data sources to an event strategy.
- Filter - specify filter conditions and apply them to each element of the input flow
Apart from this, the Merge pattern was updated to execute the flow when there is no data on the secondary branches and the Strategy pattern allows you to specify the class where you want to store your strategy results.
New Dynamic System Setting for proposition management
Valid from Pega Version 7.1.8
A new Dynamic System Setting affects the process of creating new groups on the Proposition Management landing page.
When the PropositionManagement/isOnlyVersionedProposition parameter is set to true, users can only create the versioned propositions.
When the PropositionManagement/isOnlyVersionedProposition parameter is set to false, the Create Group dialog allows users to create either the versioned or unversioned propositions (the Create versioned proposition data check box and the Decision data rule section are both displayed).
Identify, install, and manage hotfixes with the Hotfix Manager
Valid from Pega Version 7.1.8
Hotfixes are packages of files that address issues in Pega 7 and in participating Industry Applications. With Hotfix Manager, you can:
- Scan your system for installed and missing critical hotfixes and create a report that you can provide to Pegasystems Support for diagnostic purposes.
- Review the descriptions and contents of hotfixes.
- Install, rollback, and commit hotfixes.
- Manage hotfixes that include schema changes or require other special handling.
The Hotfix Manager replaces the Update Manager Hotfix Installer and System Scanner, both of which are deprecated. For more information, see Hotfix Manager identifies, installs, and manages hotfixes to Pega 7 and participating Industry Applications.
New form of the HBase rule
Valid from Pega Version 7.1.8
There is a new form of the HBase rule. While you cannot create any new instances of the Pega 7.1.7 HBase rule, legacy instances in your application remain functional. You can still use the Pega 7.1.7 instances of the HBase rule, but you cannot make changes to them.
