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". |

例如：select coalesce(id,1) from <表名> --对表中id如果为null转换成1
17、dayofweek(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
18、dayofyear(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。
19、concatt(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

备份数据库： CONNECT TO EXOA; QUIESCE DATABASE IMMEDIATE FORCE CONNECTIONS; CONNECT RESET; BACKUP DATABASE EXOA TO "/home/exoa2/db2bak/" WITH 2 BUFFERS BUFFER 1024 PARALLELISM 1 WITHOUT PROMPTING; CONNECT TO EXOA; UNQUIESCE DATABASE; CONNECT RESET;
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 用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.sql中CONNECT 项 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(在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表
数据库会恢复正常，可再用db2 list tablespaces show detail查看

33.如何知道用户下的函数?
select*fromIWH.USERFUNCTION
select*fromsysibm.SYSFUNCTIONS
34.如何知道用户下的VIEW数?
select*fromsysibm.sysviewsWHERECREATOR='USER'
35.如何知道当前DB2的版本?
