Published Release Notes

Tomcat log files moved to work directory

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:

1. Navigate to the <tomcat-home>\webapps\prweb\WEB-INF\classes directory.
2. Open the prlogging.xml file.
3. Locate the "appender" definitions section that contains the "@{web.tmpdir}" string
4. 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.

Additional upgrade scripts for new columns

In Version 6.2, additional columns (Major, Minor, and Patch) containing ruleset Version information were added to 15 tables in the PRPC database. When upgrading from a pre-Pega 7 release, scripts must be manually run after the upgrade to populate these columns.

These scripts are located in the Resource Kit, under Additional Upgrade Scripts.

• If upgrading to a single schema, run both scripts.
• If upgrading to a split schema, run the _data script against the data schema and run the _rules script against the rules schema.

Choose the scripts for your database type:

• db2zos_rulesetversion_columns_data.sql
• db2zos_rulesetversion_columns_rules.sql

• mssql_rulesetversion_columns_data.sql
• mssql_rulesetversion_columns_rules.sql

• oracle_rulesetversion_columns_data.sql
• oracle_rulesetversion_columns_rules.sql

• postgres_rulesetversion_columns_data.sql
• postgres_rulesetversion_columns_rules.sql

• udb_rulesetversion_columns_data.sql
• udb_rulesetversion_columns_rules.sql

Slow WebSphere performance on Mac platforms

Use the following JVM setting to improve WebSphere performance on Mac platforms:

-Djava.net.preferIPv4Stack=true

Split schema systems require additional privileges

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.

Database

Improvements to data handling were made for search indexing, agent processing, and filtering.  Scripts were provided for proper population of the database tables.

• Importing data from shared obj-external tables is now supported.
• A validation warning will now display when an unexposed property is used in filter or join conditions.
• A Global Search index may now be created across two databases.
• Agent processing on multiple nodes has been improved.
• Improvements were made to controls in Report Definition pages which are used in a dynamic grid.
• Filtering functionality involving special characters has been enhanced.
• Scripts have been provided to populate the RuleSetVersion Major, Minor, and Patch columns.

System Management

Refinements were made to out-of-place upgrade documentation and processes, as well as for how handling is performed for all of the database vendor specific nuances related to a deploying into a split schema environment.

• A script was created to run the data schema upgrade for z/OS systems.
• In a split-schema configuration, indexing has been enhanced.
• The product installer has been enhanced.
• The stand-alone Static Assembly Utility does not require a password for its process.
• The UpdateManager tool has been improved.

Enhanced date circumstancing option

The date range and as-of date circumstancing features have been merged into a single feature called date circumstancing. Accordingly, the new Property and Date circumstancing option provides more flexibility when you circumstance a rule. For more information, see Specializing a rule.

Renaming a system creates the required data requestors

When you rename a system, either from the System Name landing page or by updating the prconfig.xml file, any missing data requestors are automatically created by the Pega 7 Platform. The Data Admin System Setting is also created, if it is missing.

Configure Elasticsearch index nodes to ensure availability of index files

You can now configure Elasticsearch index host nodes in a Pega cluster outside of the Search landing page. This change ensures that search index files are always available by eliminating the need for manual configuration on the Search landing page. Use the new index.directory=<index_directory> command-line setting during JVM startup to indicate that this node is an index host node and to specify the directory where the index files will be hosted.

In addition, offline Elasticsearch index nodes can now be removed by using a new prpcUtils command-line option. For more information, see Managing Elasticsearch index host nodes outside of the Search landing page.

New Schema Tools and Query Inspector landing pages for Pega Cloud

Two landing pages have been added for advanced database administration tasks for Pega Cloud customers who use a Pega-hosted instance. These landing pages minimize the operations that need to be performed outside of the Pega 7 Platform. They are available only for customers who use a Postgres database.

From the new Schema Tools landing page, you can view PegaRULES and PegaDATA database schemas, increase the size of a column, add a composite or function index, update database statistics for a table, and defragment a table.

From the new Query Inspector landing page, you can enter an SQL query and generate an explain plan.

To use these landing pages, you must have the new PegaRULES:DatabaseAdministrator role. You access the landing pages by clicking Designer Studio > System > Database > Schema Tools or by clicking Designer Studio > System > Database > Query Inspector. The individual features that you can access are determined by the privileges that are assigned to you.

For more information, see Schema Tools and Query Inspector landing pages for tuning and maintaining databases in the Pega Cloud.
