Error description

  • Problem Abstract:  The unit for memory_pool_used and
    memory_pool_used_hwm should be in KB
    ----------------------------------------------------------------
    -------------------------------------------------
    
    It's easy to reproduce the problem
    
    Problem Desc:
    -----------------
    The values for memory_pool_used and memory_pool_used_hwm are not
    shown in Kb:
    Here are the steps to check the values:
    
    1- Verify the database parameter - Locklist
     Max storage for lock list (4KB)                 (LOCKLIST)
    =AUTOMATIC(4120)
    
    2- Run the command below to get the values:
    
    SELECT coalesce(varchar(memory_set_type, 20),'total') AS
    set_type, varchar(memory_pool_type,20) AS pool_type,
    varchar(db_name, 20) AS db_name, APPLICATION_HANDLE,
    memory_pool_used as "MEMORY_POOL_USED (kb)",
    memory_pool_used_hwm as "MEMORY_POOL_USED_HWM(kb)" FROM
    TABLE(MON_GET_MEMORY_POOL(NULL, CURRENT_SERVER,  -2))
    
    SET_TYPE         POOL_TYPE             DB_NAME
    APPLICATION_HANDLE                         MEMORY_POOL_USED
    (kb)             MEMORY_POOL_USED_HWM(kb)
    -------------------- -------------------- --------------------
    -----------------------------------
    ----------------------------------------
    -------------------------------------------------
    DATABASE        LOCK_MGR             TESTE1               -
    17498112                                       17498112
    DATABASE        DATABASE             TESTE1               -
    15335424                                       15335424
    
    As the LOCKLIST  value is 4120 pages of 4Kb the MEMORY_POOL_USED
    AND MEMORY_POOL_USED_HWM should be 16480Kb (4120 * 4)
    The result above shows 17498112 instead of 16480
