GLOBAL_WLM_RESPOOL_CONNECTION_INFO

This view is used to view the real-time connection usage of resource pool on all nodes in a distributed system. Only the user with the SYSADMIN or MONADMIN permission can query this view.

This view can be used to query only the data on the primary DN. You need to log in to the standby node and use the system function gs_wlm_respool_connection_info() to query the usage of concurrent tasks.
