Child case queries performance can be slow
Valid from Pega Version 7.2
Some customers have reported that performance is slow when they execute queries on child cases. This issue is often indicated by PEGA0005 (query time exceeded limit) alerts that can be correlated to these queries in the logs. To resolve the issue, add a database index to each of your work tables by using a multicolumn index on the pxCoverInsKey, pxObjClass, and pyStatusWork columns.
See Performance improvements for child case queries.
High number of busy waits when using Oracle SecureFiles
Valid from Pega Version 7.2.1
You might experience a high number of buffer busy waits when using Oracle SecureFiles for BLOB storage. An Oracle buffer busy wait occurs when a session cannot access a database block in the buffer cache, because another session is either reading the block into the buffer or changing the buffer. As a best practice, use Oracle 11.2.0.4 or later, because earlier versions have more problems with SecureFiles. In addition, to minimize the number of busy waits, set the hidden Oracle parameter _securefiles_concurrency_estimate to 50, and partition the table by using a composite range hash partition that is based on the pxCreateDateTime and pzInskey columns.
For more information, see Troubleshooting: High number of busy waits when using Oracle SecureFiles.
Email approval and instantiation not supported on multitenant systems
Valid from Pega Version 7.2.1
The Enable email approval check box appears on the General tab of an approval step in Case Designer in multitenant systems. It also appears on the Approval shape in Designer Studio. In addition, in Designer Studio, the Settings tab in Case Designer displays the option to configure email instantiation. However, because configuring email listeners is not supported on multitenant systems, you cannot enable email approval or email instantiation.
Verify ML Readiness error: Upgrades from Pega 7.1.0 through 7.1.8 do not replace nonversioned rules
Valid from Pega Version 7.2
Upgrading from any Pega 7 Platform version between Pega 7.1 and Pega 7.1.8 to Pega 7.2 does not automatically replace nonversioned rules. If you revalidated and saved a Pega 7.1.x rule after the timestamp on the Pega 7.2 version of the rule, upgrading to Pega 7.2 does not overwrite the saved rule. You might see either of the following behaviors:
- The upgrade fails with the following error message:
Verify ML Readiness - The upgrade succeeds, but you might be unable to open changed rule forms.
If the upgrade fails, see the Pega 7 Platform Upgrade Guide to force the upgrade.
This known issue does not affect Pega 7.1.9. After the upgrade has finished, apply Hotfix 27288. For information about obtaining and applying hotfixes, see Hotfix Manager.
Extract marker file not created at startup
Valid from Pega Version 7.2.1
The extract marker file (PegaRULES_Extract_Marker.txt) is not created at startup, because the rule utility libraries no longer need it. If you used to use the extract marker file to clear the static content file-based cache, to look up lists, or to control starting activities with web nodes, you can delete the contents of the PegaRULES temporary directory instead.
Upgrade/update fails if PostGIS is applied to PegaRULES or PegaDATA schema
Valid from Pega Version 7.2.1
If you use the PostGIS extension to a PostgreSQL database, upgrading or updating the Pega 7 Platform fails if the extension has been applied to either the PegaRULES or PegaDATA schema. PostGIS can be applied to any other schema.
