Cause

Governor limits are stored in the database starting Clarity PPM 15.6.1, but direct database updates are not supported.

Environment

Clarity 15.6.1 or higher.

Resolution

Governor limits have a current limit, a default limit (out of the box value), and a critical limit (maximum value). It is not possible to increase the current limit past the critical limit.

It's recommended to review the recommended limits at Governor Settings (Maximum Data Limits). Increasing the limits above the defined recommendations can impact performance.

If you are an On Premise Customer:

There are new admin commands to modify the default governor limit settings.

 

For example, to modify the Max XML Nodes limit from current / default of 150,000 to 200,000 nodes, execute this command:

admin governors -set MAX_XML_NODES 200000

The full list of Governor Settings and Admin Commands can be found in the links in the Additional Information section.

 

If you are a SaaS (On Demand) Customer:

The governor limits are set to the most optimal values, and are not changed in SaaS.

 

 

A restart of APP and NSA services is necessary for the new value to take effect.
