  •  Identify the session that has a lock on the  table and take action kill it,let it finish,identify the bottleneck.

     

    See lock

     

    select * from locks:

     

    To monitor oll your sessions:

    - this will generate the kill syntax as well

     

    SELECT
    node_name
    ,user_name
    ,'SELECT CLOSE_SESSION(''' || session_id || ''');' AS CloseSession
    ,statement_start
    ,(GETDATE() - statement_start)::INTERVAL AS current_statement_duration
    ,REGEXP_REPLACE(current_statement,'[\r\n\t]',' ') AS current_statement
    ,session_id
    ,transaction_id
    ,statement_id
    ,client_hostname
    ,client_os
    ,login_timestamp
    ,runtime_priority
    ,ssl_state
    ,authentication_method
    ,transaction_start
    ,GETDATE() AS Today
    FROM v_monitor.sessions
    ORDER BY current_statement_duration DESC
    ;
