Post-install   steps

Required steps:

 

In order to start using DB2 you need to   logon using a valid user ID such as the DB2 instance owner's ID   "db2inst1".

 

You can connect to the DB2 instance   "db2inst1" using the port number "50000". Record it for   future reference.

 

Optional steps:

 

To validate your installation files,   instance, and database functionality, run the Validation Tool,   /opt/ibm/db2/V10.5/bin/db2val. For more information, see "db2val"   in the DB2 Information Center.

 

Open First Steps by running   "db2fs" using a valid user ID such as the DB2 instance owner's ID.   You will need to have DISPLAY set and a supported web browser in the path of   this user ID.

 

You should ensure that you have the   correct license entitlements for DB2 products and features installed on this   machine. Each DB2 product or feature comes with a license certificate file   (also referred to as a license key) that is distributed on an Activation CD,   which also includes instructions for applying the license file. If you   purchased a base DB2 product, as well as, separately priced features, you   might need to install more than one license certificate. The Activation CD   for your product or feature can be downloaded from Passport Advantage if it   is not part of the physical media pack you received from IBM. For more   information about licensing, search the Information Center   (http://publib.boulder.ibm.com/infocenter/db2luw/v10r5/index.jsp) using terms   such as "license compliance", "licensing" or   "db2licm".

 

To use your DB2 database product, you   must have a valid license. For information about obtaining and applying DB2   license files, see  http://pic.dhe.ibm.com/infocenter/db2luw/v10r5/topic/com.ibm.db2.luw.qb.server.doc/doc/c0061199.html.

 

Refer to "What's New"   http://publib.boulder.ibm.com/infocenter/db2luw/v10r5/topic/com.ibm.db2.luw.wn.doc/doc/c0052035.html   in the DB2 Information Center to learn about the new functions for DB2 10.5.

 

Verify that you have access to the DB2   Information Center based on the choices you made during this installation. If   you performed a typical or a compact installation, verify that you can access   the IBM Web site using the internet. If you performed a custom installation,   verify that you can access the DB2 Information Center location specified   during the installation.

 

Review the response file created at   /root/db2expc.rsp.  Additional   information about response file installation is available in the DB2   documentation under "Installing DB2 using a response file".

1.14.24查看表结构

db2 describe table <表名>       --查看表结构

db2 describe select * from user.tables

 

1.14.25查看所有连接

db2 list application --查看所有连接(需要连接到具体数据库才能查看)

 

1.14.26数据库导出

db2look -d <数据库名> -u <用户> -e -o <脚本名称>.sql        --导出数据库的表结构,其中用户空间一般为db2admin/db2inst1

 

db2look -d <数据库名> -u <用户> -t <1> <2>  -e -o <脚本名称>.sql   --导出数据库中表1和表2的表结构

 

db2move <数据库名> export              --导出数据库数据

 

db2move <数据库名> export -tn <1>,<2>       --导出数据库中表和表数据

 

1.14.27数据库导入

db2 -tvf    <脚本名称>.sql       --把上述导出的表结构导入到数据库表结构

db2move <数据库名> load -lo replace   --把上述“db2move <数据库名> export “导出的数据导入到数据库中并把相同的数据替换掉  

在实际使用过程中,如果用到db2自增主键,需要使用by   default 而不是always,功能是一样的,但这样在数据移植时候会很方便!

 

1.14.28修改编码

db2set db2codepage=1208        --修改页编码为1208

 

1.14.29查看表空间

db2 list tablespaces                  --列出表空间

 

1.14.30其他命令

1.14.30.1 db2 catalog  

db2 catalog tcpip node <接点名称> remote <远程数据库地址> server <端口号>  --把远程数据库映射到本地接点一般为50000

db2 catalog db <远程数据库名称> as <接点名称>  at node PUB11                       --远程数据库名称到本地接点

1.14.30.2 grant

grant dbadm on database to user bb

 

1.14.30.3 其它

select * from czyxx fetch first 1 rows   only

db2look -d ylbx -u db2admin -w -asd -a -e   -o a.txt

fetch first 10 rows  only     --列出表中前10条数据

select * from <表名> fetch first 10 rows only

 

1.14.31其它

15fetch first 10 rows    only   --列出表中前10条数据

 

例如:select *   from <表名> fetch   first 10 rows only

 

16coalesce(字段名,转换后的值)       --对是null的字段进行值转换

 

例如:select   coalesce(id,1)  from <表名>    --对表中id如果为null转换成1

 

17dayofweek(日期)     --计算出日期中是周几(1是周日,2是周一.......7是周六)

 

         dayofweek_iso    --计算出日期中是周几(1是周一.......7是周日)

       

 例如:dayofweek(date(2008-01-16))   --它会返回是4,代表星期三

            

             dayofweek_iso(date(2008-01-16))   --它会返回是3,代表星期三

 

18dayofyear(日期)   --一年中的第几天,范围在1-366范围之内

 

注意:参数中日期的格式是YYYY-MM-DD的形式,如果不是需要进行转换,否则函数不能使用

 

例如:日期是20080116必须要进行转换

 

dayofweek(concat(concat(concat(substr(openDate,1,4),'-'),concat(substr(openDate,5,2),'-')),substr(openDate,7,2)))   as week)

 

这样格式正确的。

 

19concatt(参数1,连接值)       --把参数1加上连接值组成一个新值。

 

  例如: concat('aa','b')    --返回是aab

 

连接数据库:

 

      connect to [数据库名] user [操作用户名] using [密码]

      create bufferpool ibmdefault8k IMMEDIATE    SIZE 5000 PAGESIZE 8 K ;

创建缓冲池(16K)(OA_DIVERTASKRECORD)

      create bufferpool ibmdefault16k IMMEDIATE    SIZE 5000 PAGESIZE 16 K ;

以下是小弟在使用db2move中的一些经验,希望对大家有所帮助。

 

db2       connect     to    YOURDB    

连接数据库

 

db2look -d    YOURDB      -a -e -x -o creatab.sql

导出建库表的SQL

 

db2move     YOURDB      export

db2move将数据备份出来

 

vi       creatab.sql

如要导入的数据库名与原数据库不同,要修改creatab.sqlCONNECT

如相同则不用更改

 

db2move      NEWDB    load

将数据导入新库中

 

在导入中可能因为种种原因发生中断,会使数据库暂挂

db2        list tablespaces     show     detail

如:

          详细说明:

         装入暂挂

总页数                            = 1652

可用页数                          = 1652

已用页数                           = 1652

空闲页数                           = 不适用

高水位标记(页)                   = 不适用

页大小(字节)                     = 4096

盘区大小(页)                     = 32

预读取大小(页)                   = 32

容器数                             = 1

状态更改表空间标识                      = 2

状态更改对象标识                        = 59

 

db2 select tabname,tableid from   syscat.tables where tableid=59

查看是哪张表挂起

 

表名知道后到db2move.lst(db2move    YOURDB      export的目录中)中找到相应的.ixf文件

db2 load from tab11.ixf of ixf terminate   into db2admin.xxxxxxxxx

tab11.ixf对应的是xxxxxxxxx

 

数据库会恢复正常,可再用db2   list tablespaces show detail查看

 

 

 

30.不能通过GRANT授权的权限有哪种?

34.如何知道用户下的VIEW?

 

select*fromsysibm.sysviewsWHERECREATOR='USER'  

 

35.如何知道当前DB2的版本?

 

select*fromsysibm.sysvERSIONS

 

36.如何知道用户下的TRIGGER?

 

select*fromsysibm.SYSTRIGGERSWHERESCHEMA='USER'  

 

37.如何知道TABLESPACE的状况?

 

select*fromsysibm.SYSTABLESPACES

 

38.如何知道SEQUENCE的状况?

 

select*fromsysibm.SYSSEQUENCES

 

39.如何知道SCHEMA的状况?

40.如何知道INDEX的状况?

 

select*fromsysibm.SYSINDEXES

 

41.如何知道表的字段的状况?

 

select*fromsysibm.SYSCOLUMNSWHERETBNAME='AAAA'  

 

42.如何知道DB2的数据类型?

 

select*fromsysibm.SYSDATATYPES

 

43.如何知道BUFFERPOOLS状况?

 

select*fromsysibm.SYSBUFFERPOOLS
