Remove JVM settings from prior installations

Valid from Pega Version 7.1.1

JVM memory settings ​defined in the setupDatabase.properties file to support a prior installation need to be removed. 

Memory settings are now handled by the installation program. Duplicating these settings may cause installation or upgrade failures. 

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.

Required DB2 settings for LUW and z/OS

Valid from Pega Version 7.1.1

Installations on DB2 databases for LUW and z/OS require a minimum logging file size (4096) and a default table space page size (32K).

To set the table space page size to 32K:

  1. Stop the system.
  2. Rename one table (“TableX”) to backup (“TableXBackup”).
  3. Create a new table space that uses a 32K page size.
  4. Copy “TableXBackup” to “TableX” in the new table space.
  5. Restart the system and test to verify there are no issues.
  6. Drop the backup table (or keep it for future reference).

Additional information is available in the "Adjusting the log space size in upgraded databases" article: https://pic.dhe.ibm.com/infocenter/db2luw/v9r7/index.jsp?topic=%2Fcom.ibm.db2.luw.qb.upgrade.doc%2Fdoc%2Ft0023289.html

No direct upgrade to multitenant setup

Valid from Pega Version 7.1.1

It is not possible to upgrade directly to a multi-tenant setup. A Pega 7 application may be exported and then imported into a multi-tenant system, with the administrator making the decision as to whether this then becomes a tenant system or a shared system.

 

Applications developed in versions prior to Pega 7 must be upgraded to a Pega 7 standard system, and then exported and imported into a multi-tenant system. See the Multitenancy Administration Guide for full details.

Upgrade changes system name

Valid from Pega Version 7.1.1

As of Pega 7.1.7, the following renaming behavior no longer occurs.

The upgrade process renames your system to “PRPC” and modifies any custom requestor rules in your application to use this name. After the upgrade completes, you must apply these changes to revert your system:

  1. Identify all custom requestor rules (browser, batch, app, portal) with access groups that point to prior versions of PRPC.
  2. Open the relevant access groups (for example, PRPC:Unauthenticated and PRPC:Agents) and update the name and version fields to point to the current PegaRULES application.
  3. Reset your system name to its original value. You can set the Dynamic System Setting prconfig/identification/systemName/default or use the Designer Studio > System > Settings > System Name landing page.
  4. Restart the system.

Run cleanup.bat/sh script only before upgrading

Valid from Pega Version 7.1.1

Prior to upgrading the rulebase, you can optionally run the cleanup.bat/sh script to remove older rules from the database.

Run this script before you upgrade your rulebase, or the script may delete needed rulesets. For more information about running the cleanup.bat/sh script, refer to the Upgrade Guide specific to your release version.

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.

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.

Rules Assembly cache is deprecated

Valid from Pega Version 7.3.1

Rules Assembly (RA) cache and custom settings for its corresponding fua/assemblyCacheModeprconfig.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 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.
