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.
- 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 page.
- Copy the contents of the <distribution>\ResourceKit\ZOSDisableTriggerScripts directory into the <distribution>\scripts\ directory.
- Run fixZosTriggers.bat or fixZosTriggers.sh with the following arguments:
--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.>
fixZosTriggers --action preupgrade --dataschema pegadata --oldrulesschema pegarules --newrulesschema newrules --automaticddl false
- 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.
- Run the data schema upgrade as described in the Pega 7 Platform Upgrade Guide.
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
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
pr4_rule_vw tables and perform other processing, those triggers must be reimplemented. When doing so, you must be careful to not modify the

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.
