【Teradata】开启LockLogger与dumplocklog工具使用（含lokdisp工具说明）

disp gen
modify gen 9=true
write

tpareset -f change date
psh pdestate //查看数据库状态，为running则启动成功

//DBC用户执行,创建用户LockLogUsr,空间0.创建数据库LockLogData,空间200G
CREATE USER "LockLogUsr" FROM "dbc"
AS PERM = 214748364800
PASSWORD = "lock2014"
ACCOUNT = (‘DBC‘)
;

CREATE DATABASE "LockLogData" FROM "LockLogUsr"
AS PERM=214748364800
NO FALLBACK
NO BEFORE JOURNAL
NO AFTER JOURNAL
;

//DBC用户执行,赋权
grant all privileges on LockLogData to LockLogUsr with grant option;
grant select on dbc to LockLogUsr;

//root用户登录teradata节点,使用cnsterm启动dumplocklog
在#提示符下输入”cnsterm 6”后回车
输入start dumplocklog回车，之后会提示在windows x下运行（x通常为1）。
按ctrl+c退出当前界面，在#提示符后输入 cnsterm 1回车,出现如下界面：

locklogusr,lock2014（这里输入数据库用户名和密码）

Enter the table name where the lock log entries will be written (? For Help, Q/q to Quit):

Do you want this utility to create table LOCKLOGDATA.LOCKLOG? (Y/N)
y （Y：指定的是新建表  N：指定的是一个已经存在的表）
Table locklogger.LOCKLOG has been created.
Enter the time constraint to control selection of lock log entries that were generated AT
or LATER than this time YYMMDD HHMMSS (? For Help, Q/q to Quit):
20140427 060000 （指定一个开始时间，如果要指定所有时间则输入*即可）
Enter the time constraint to control selection of lock log entries that were generated AT
or PRIOR to this time YYMMDD HHMMSS (? For Help, Q/q to Quit):
20140427 070000  （指定一个结束时间，如果要指定所有时间则输入*即可）
Enter the object constraint for selection of lock log entries (? For Help, Q/q to Quit):
?
Specify the database objects for which lock delay should be selected. Up to 10 objects can

- <name1>.<name2> - name1 specifies a database and name2 specifies a table.
- <name>.* - name specifies a database and all tables under it.

- * - All databases and tables.   （可以指定数据库或者表名，也可以指定所有对象则输入*）
- <Return> - Done.
- Q - Terminate the utility.
Note that if database or table name is specified, it has to exist or an error will be
returned.
Enter the object constraint for selection of lock log entries (? For Help, Q/q to Quit):
sysadmin.fastlog (指定收集锁信息的对数据库或者表名，或者所有对象)

Enter（回车键表示没有其它对象要收集）
