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:
- Oracle —
OracleMTupgrade.sql - PostgreSQL —
PostgresMTupgrade.sql
For updates, these scripts are located in the /scripts/ddl directory.
For upgrades, these scripts are located in the /Resourcekit/AdditionalUpgradeScripts directory.
Unclear error message when saving shared class instance in tenant layer
Valid from Pega Version 7.1.5
If you attempt to save a shared class instance from the tenant layer, Pega 7 displays this message:
This record has x errors. Save Failed: There was a problem saving an instance of class: Error Code: <none> SQL State: <none> Message: <none>
You cannot save a shared instance from the tenant layer if that instance cannot be overridden.
Updated Word merge support with Microsoft Silverlight plug-in
Valid from Pega Version 7.1.3
Starting in this release, Pega 7 features that integrate with the Word merge capability are now cross-browser. ActiveX controls (which are only compatible with Internet Explorer) have been replaced with Microsoft Silverlight. This plug-in must be downloaded separately from Microsoft because it is not shipped with Pega 7.
Common features that are affected by this change include the Specification form and Case Type landing page.
Prior to using these features, see the release note Word merge support with Microsoft Silverlight plug-in for more information about setting up their client systems.
