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. 

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.

Data schema error on z/OS split schema upgrades from versions before Pega 7.1.8

Valid from Pega Version 4.1

When upgrading to a split schema on Pega 7.x with IBM DB2 for z/OS, you see an error during the data schema upgrade when the system tries to drop the PRPC_Updatescache procedure. Because triggers on rules tables use PRPC_Updatescache, you must use the ZOSDisableTriggerScripts to disable these triggers before you update the data schema.

  1. Follow the instructions in the Pega 7 Platform Upgrade Guide to upgrade the rules schema, but stop immediately before you upgrade the data schema with the upgrade.bat or upgrade.sh script. The Pega 7 Platform Upgrade Guide is on the Support > Deployment Guides page.
  2. Copy the contents of the <distribution>\ResourceKit\ZOSDisableTriggerScripts directory into the <distribution>\scripts\ directory.
  3. Run fixZosTriggers.bat or fixZosTriggers.sh with the following arguments:
    --action preupgrade
    --dataschema <data schema name>
    --oldrulesschema <old rules schema name. If you are upgrading from a single-schema system, this is the data schema name.>
    --newrulesschema <new rules schema name>
    --automaticddl <Optional. Set to true to automatically apply the disable trigger SQL scripts.>

    For example:
    fixZosTriggers --action preupgrade --dataschema pegadata --oldrulesschema pegarules --newrulesschema newrules --automaticddl false

  4. If you did not set --automaticddl to true in the previous step, run the <distribution>\schema/disable.sql script to manually disable the trigger SQL scripts.
  5. Run the data schema upgrade as described in the Pega 7 Platform Upgrade Guide.

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.

DB2-LUW database logfile size increase

Valid from Pega Version 7.1.5

This issue applies to DB2-LUW database platforms only.
 

To avoid running out of logfile space due to large transaction sets during the rule base load of a Pega 7.1.x install, upgrade, or maintenance level update, systems supported by a DB2-LUW database platform should increase the LOGFILSIZ parameter to at least 4096 pages from the default size of 1000 pages.

After the size has been increased, restart the database to ensure that the new setting is loaded into the database correctly.

Need to run script before updating Multitenant systems

Valid from Pega Version 7.1.5

When updating or upgrading a Multitenant system from Pega 7.1.5 or 7.1.6 to Pega 7.1.7, if that system uses either an Oracle or a PostgreSQL database, you may encounter the error:

“Table must be empty to add column.”

The Multitenant architecture requires an additional column on a number of the PRPC database tables (“pzTenantID”). In Pega 7.1.7, two additional PRPC tables were tenant-qualified: pc_schedule_task and pr_index_schedule_task. The Multitenant column is added to these tables by the update/upgrade process. However, Oracle and PostgreSQL do not allow the addition of a non-null column to an existing table unless the table is empty, so updating or upgrading systems on those databases displays the error detailed above.

To avoid this error, before beginning the update or upgrade, it is necessary to run a script:

  • OracleOracleMTupgrade.sql
  • PostgreSQLPostgresMTupgrade.sql

For updates, these scripts are located in the /scripts/ddl directory.

For upgrades, these scripts are located in the /Resourcekit/AdditionalUpgradeScripts directory.

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.

End of support for Microsoft Internet Explorer 8 and quirks mode applications in Pega 7.1.9

Valid from Pega Version 7.1.9

In accordance with Microsoft’s announcement to discontinue support for Internet Explorer 8 in January 2016, Pega 7.1.9 does not support Internet Explorer 8, nor does it support non-HTML5 standard user interfaces.

You must upgrade to Microsoft Internet Explorer 9 or later or use Google Chrome, Apple Safari, or Mozilla Firefox. If you are using Internet Explorer 9 or later, you must turn off compatibility mode by accessing the Compatibility View settings.

Note the following:

  • Pega 7.1.9 does not support user interface rules that are not based on HTML5 standards (rules in quirks mode).
  • If you use applications that are rendered in quirks mode, which enables Pega 7 to correctly display and render non-HTML5 standard user interfaces, you must update them to standards-based HTML5 user interfaces when you upgrade to Pega 7.1.9 or later. Pega 7 provides automated tools to help you migrate your applications.
  • Pegasystems Global Customer Support will not investigate or fix any Pega 7.1.9 bugs or support requests that are exclusive to Internet Explorer 8 or quirks mode user interfaces.

You can quickly identify which components of your application user interface are not HTML5 standards-based by clicking Designer Studio > User Interface > HTML5 Application Readiness.

Upgrading to Pega 7.1.9 and a newer browser offers the following benefits:

  • These browsers are HTML5 and CSS3 compliant.
  • New features are supported and existing features work as intended.
  • The Pega 7 Platform user interface is displayed and rendered as intended.
  • Browser security is enhanced.

If you have additional questions about browser support, see the Platform Support Guide or contact Pegasystems Global Customer Support.

Updated default system pulse processing settings

Valid from Pega Version 7.1.9

The default settings for system pulse processing have been updated in this release.

Upgrades to Pega 7.1.9 from a previous version of the Pega 7 Platform use database pulse by default. Database pulse synchronizes rule changes at a periodic interval across all nodes in a system.

New installations of Pega 7.1.9 use cluster-based pulse by default. Cluster-based pulse immediately updates rule changes across all nodes in a system after the changes are saved.

You can change the database pulse setting to the cluster-based pulse setting by updating the value attribute for initialization/pulse/transport to "cluster" in the prconfig.xml file or in the Dynamic System Settings. Changing from database pulse to cluster-based pulse requires a full cluster restart after the changes are made.
