A global deadlock refers to a deadlock between Unity and Teradata Database. A global deadlock may occur when Unity uses passive and managed routing at the same time with the option Passive Routing Allow Managed Writes selected.
You can change how often Unity attempts to detect a global deadlock between Unity and a Teradata system.
From unityadmin, enter the following command with the new time interval:
CONFIG UPDATE globaldeadlockdetectioninterval <numberofseconds> REASON 'Enabling global deadlock detection';
