Vertica Analytics Platform Version 10.1.x Documentation
Returns information about deadlocked clients and the resources they are waiting for.
Use DUMP_LOCKTABLE if Vertica becomes unresponsive:
- Open an additional vsql connection.
Execute the query:
=> SELECT DUMP_LOCKTABLE();
The output is written to vsql. See Monitoring the Log Files.
You can also see who is connected using the following command:
=> SELECT * FROM SESSIONS;
Close all sessions using the following command:
=> SELECT CLOSE_ALL_SESSIONS();
Close a single session using the following command:
=> SELECT CLOSE_SESSION('session_id');
You get the session_id value from the V_MONITOR.SESSIONS system table.
