Required Oracle optimization parameter

Valid from Pega Version 7.1.3

To optimize performance, set the Oracle parameter optimizer_index_cost_adj to a value between 20 and 25. If this value is not set, the system can run exceedingly slowly, potentially blocking users from login.

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 upgrade instructions missing properties

Valid from Pega Version 7.1.3

If you upgraded from 5.x, 6.x, or 7.x using the instructions in previous versions of the upgrade guide, you may have neglected to set the properties below in your migrateSystem.properties file when you migrated your upgraded schema to the source system:

 

pega.rules.objects.generate=true

pega.rules.objects.apply=true

 

If these properties were not set during an upgrade that splits the schema, your environment does not have the indexes, triggers, and primary keys on the rules tables.

 

To check for this issue, see if the pr4_base and pr4_rule rules tables in your existing rules schema are missing primary keys. If they are, use the SQL scripts in the ResourceKit\MigrationRecoveryScripts directory of the release to cleanup duplicate rules that were created due to this issue. Follow the steps below to run the scripts.

To run the scripts on Microsoft SQL, Oracle, or PostgreSLQ

  1. Take down any app servers using the affected schema.
  2. Backup your database.
  3. Replace all instances of @RULES_SCHEMA in <database>_cleanDups.sql with the name of the schema that contains the pr4_base table.
  4. Run the <database>_cleanDups.sql script on the database with vendor tools (sqlPlus, SQL Server Management Studio, etc).
  5. Replace all instances of @RULES_SCHEMA in <database>_fix_vw_table.sql with the name of the schema that contains the pr4_base table.
  6. Run the <database>_fix_vw_table.sql script on the database with vendor tools (sqlPlus, SQL Server Management Studio, etc).
  7. Generate and apply the ddl using the command line generateDDL command. Check the installation guide for your database or the upgrade guide for details about how to use the generateDDL command line script.
  8. Rebuild the indexes for the tables in your rules schema using vendor tools. This is necessary so that your system runs at an optimum speed.
  9. Optionally upgrade to the latest release, at this point your database is ready to be upgraded or used depending on your needs.

      

To run the scripts on DB2 for LUW or z/OS

  1. Take down any app servers using the affected schema.
  2. Backup your database.
  3. Run the <database>_cleanDups.sql script on the database with vendor tools (UDB CLP, Data Studio, etc) to create the CLEANSE_RULES_DUPS stored procedure.
  4. Run the query Call CLEANSE_RULES_DUPS(‘<rulesSchema>’); where <rulesSchema> is the name of schema that contains the pr4_base table.
  5. After the previous step is complete drop the CLEANSE_RULES_DUPS procedure.
  6. Replace all instances of @RULES_SCHEMA in <database>_fix_vw_table.sql with the name of the schema that contains the pr4_base table.
  7. Run the <database>_fix_vw_table.sql script on the database with vendor tools (UDB CLP, Data Studio, etc).
  8. Generate and apply the ddl using the command line generateDDL command. Check the installation guide for your database or the upgrade guide for details about how to use the generateDDL command line script.
  9. Rebuild the indexes for the tables in your rules schema using vendor tools. This is necessary so that your system runs at an optimum speed.
  10. Optionally upgrade to the latest release. At this point your database is ready to be upgraded or used depending on your needs.

Synchronized database and application server settings

Valid from Pega Version 7.1.3

Configure your database and application server to use the same time zone and character encoding to avoid conflicts.

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.

JavaMail API upgrade has potential SMTP configuration error

Valid from Pega Version 7.1.8

The JavaMail API has been upgraded from 1.4.1 to 1.5.2 in this release. This improvement provides greater compatibility and secure connectivity with leading industry email servers.

During the upgrade process, there is a known issue for some configurations of email servers, including Microsoft Exchange Server, that requires the use of an additional setting. After upgrading to this release, if you experience authentication failures when attempting to send email or test SMTP connectivity, do one of the following:

  • Recommended: Review the Microsoft Exchange email server settings to ensure proper configuration for SMTP authentication. In some cases, the use of port 587 instead of the traditional default SMTP port 25 has been shown to address this issue.
  • Create the following Dynamic System Setting with the value "true," and then restart email listeners:

Owning Ruleset: Pega-IntegrationEngine

Setting Purpose: javamail/NoAuthMechanismsRetry

After any email server configuration or upgrade, it is recommended that email listeners are re-tested without using this Dynamic System Setting.

See About Email Account data instances for information on configuring email account records.

Creating data page unit tests in Internet Explorer 8

Valid from Pega Version 7.1.8

When creating data page unit tests, selecting a parent property does not automatically select the child properties when using Internet Explorer 8.

Page and page list properties to be included in a data page unit test are selected on the Create test screen by selecting a check box next to the property name. Normally, selecting the check box of a parent property automatically selects all subsequent child properties as well. When using Internet Explorer 8, child properties are not automatically selected when the parent property's check box is selected.

The solution requires selecting all of the desired child properties individually. Select the check box next to each child property to include it in the data page unit test.

Schema not found error when importing a Rule-Admin-Product file

Valid from Pega Version 7.1.8

If you import a Rule-Admin-Product file (RAP) file that includes a schema that has a view, grammar parsing changes can mean that the Pega 7 Platform is unable to find the schema.

To enable the Pega 7 Platform to find the schema:

  1. Review the error message that indicates that the schema was not found and identify the following items:
    • The name of the schema that is causing the error
    • The table name in the format: wrong_schema_name.table_name...
    • The DDL that the Pega 7 Platform is trying to apply
  2. Use the table name to identify the correct schema name in your system. This schema is usually your data schema, but might also be an external database.
  3. Download the DDL.
  4. Correct the schema name and save the DDL.
  5. Manually apply the DDL.
