Description

Activating query profiling on the system level in combination with high user concurrency could cause the database to be overloaded. In these cases, users may notice the following symptoms:

  • unresponsive system
  • reduced query concurrency
  • very high login times

Workaround

Turn off query profiling on the system level and restart the database. You can activate query profiling for a session when needed.

Fix

The database will remain responsive in these scenarios.
