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". |

dayofweek_iso --計算出日期中是周幾(1是周一.......7是周日)
例如：dayofweek(date(2008-01-16)) --它會返回是4，代表星期三
dayofweek_iso(date(2008-01-16)) --它會返回是3，代表星期三
18、dayofyear(日期) --一年中的第幾天，范圍在1-366范圍之內
注意：參數中日期的格式是YYYY-MM-DD的形式，如果不是需要進行轉換，否則函數不能使用
例如：日期是20080116必須要進行轉換
dayofweek(concat(concat(concat(substr(openDate,1,4),'-'),concat(substr(openDate,5,2),'-')),substr(openDate,7,2))) as week)
這樣格式正確的。
19、concatt(參數1，連接值) --把參數１加上連接值組成一個新值。
例如： concat('aa','b') --返回是aab

48. 修改表結構
alter table yhdab ALTER kh SET DATA TYPE varchar(13);
alter table yhdab ALTER ID SET DATA TYPE varchar(13);
alter table lst_bsi alter bsi_money set data type int;
insert into yhdab values
('20000300001','123456','user01','20000300001'),
('20000300002','123456','user02','20000300002');
49. 業務類型說明

備份數據庫： 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中的一些經驗，希望對大家有所幫助。
db2 connect to YOURDB 連接數據庫
db2look -d YOURDB -a -e -x -o creatab.sql 導出建庫表的SQL
db2move YOURDB export 用db2move將數據備份出來
vi creatab.sql 如要導入的數據庫名與原數據庫不同，要修改creatab.sql中CONNECT 項 如相同則不用更改
db2move NEWDB load 將數據導入新庫中
在導入中可能因為種種原因發生中斷，會使數據庫暫掛 db2 list tablespaces show detail 如： 詳細說明： 裝入暫掛 總頁數 = 1652 可用頁數 = 1652 已用頁數 = 1652 空閑頁數 = 不適用 高水位標記（頁） = 不適用 頁大小（字節） = 4096 盤區大小（頁） = 32 預讀取大小（頁） = 32 容器數 = 1 狀態更改表空間標識 = 2 狀態更改對象標識 = 59
db2 select tabname,tableid from syscat.tables where tableid=59 查看是哪張表掛起
表名知道后到db2move.lst(在db2move YOURDB export的目錄中)中找到相應的.ixf文件 db2 load from tab11.ixf of ixf terminate into db2admin.xxxxxxxxx tab11.ixf對應的是xxxxxxxxx表
數據庫會恢復正常，可再用db2 list tablespaces show detail查看
30.不能通過GRANT授權的權限有哪種?
SYSAM
SYSCTRL
SYSMAINT
要更該述權限必須修改數據庫管理器配置參數
31.表的類型有哪些?
永久表(基表)
臨時表(說明表)
臨時表(派生表)
32.如何知道一個用戶有多少表?
SELECT*FROMSYSIBM.SYSTABLESWHERECREATOR='USER'
33.如何知道用戶下的函數?
select*fromIWH.USERFUNCTION
select*fromsysibm.SYSFUNCTIONS
34.如何知道用戶下的VIEW數?
select*fromsysibm.sysviewsWHERECREATOR='USER'
35.如何知道當前DB2的版本?
select*fromsysibm.sysvERSIONS
36.如何知道用戶下的TRIGGER數?
select*fromsysibm.SYSTRIGGERSWHERESCHEMA='USER'
37.如何知道TABLESPACE的狀況?
select*fromsysibm.SYSTABLESPACES
38.如何知道SEQUENCE的狀況?
select*fromsysibm.SYSSEQUENCES
39.如何知道SCHEMA的狀況?
select*fromsysibm.SYSSCHEMATA
40.如何知道INDEX的狀況?
select*fromsysibm.SYSINDEXES
41.如何知道表的字段的狀況?
select*fromsysibm.SYSCOLUMNSWHERETBNAME='AAAA'
42.如何知道DB2的數據類型?
select*fromsysibm.SYSDATATYPES
43.如何知道BUFFERPOOLS狀況?
select*fromsysibm.SYSBUFFERPOOLS |
