    List two ways in which a system utility can be started.

    Explain how to use the following utilities to maintain a Teradata database:

    – DBS Control
    – Ferret Packdisk
    – Ferret Defragment
    – Ferret Scandisk
    – Checktable
    – Table Rebuild
    – Recovery Manager
    – Showlocks
    – UpdateSpace
    – Vprocmanager

    List the order in which to execute the Checktable and Scandisk utilities.

    1.utilities工具启动方式

    (1)输入命令行直接启动

    tpareset
    pdestate
    dbscontrol
    vprocmanager
    schmon
    dip

    如果提示找不到命令,可输入tdatcmd命令添加命令所在目录到当前环境变量,如下:

    tdatcmd  

    (2)Supervisor Window启动

    cnsterm 6       ==>Linux(cnsterm 1-6)
    cnstool 6       ==>Windows
    Remote Console ==>ViewPoint

    (1)查看主要内容

    • General
    • File System
    • Performance
    • Checksum
    • Compression
    • Statistics
    • Storage (used if temperature based compression is enabled or if TVS is licensed)

    (2)三种启动方式

    • Command line:输入tdatcmd后,输入dbscontrol 
    • Viewpoint Remote Console :选择DBS Control
    • Supervisor Window:输入START DBSCONTROL

    (3)显示、帮助和退出

    DISPLAY GENERAL | FILESYS | PERFORMANCE | COMPRESSION | …    ==>显示
    HELP    GENERAL | FILESYS | PERFORMANCE | COMPRESSION | …    ==>帮助
    QUIT     ==>退出

    (4)修改方法

    display general
    modify general 14 = 50       ==>Use the modify command to change flag 14 (Century Break)
    write                        ==>Write changes to the GDO

    (5)参数信息

    (6)开启并使用dbscontrol内部参数

    上述描述的均为外部参数,可以使用如下命令开启并查看内部参数:
