DB2创建联邦数据库

联邦数据库配置步骤: 
db2 update dbm cfg using federated yes #参数配置
db2 catalog node #编目节点
db2 catalog database #编码远程数据库
db2 connect to db #连接本地数据库
db2 create wrapper drda #创建wrapper
db2 create server　　 #创建服务器
db2 create usermapping　#创建用户mapping 
db2 create nickname　 #创建远程数据库对象nickname
********************************************************************************* 
1.设置数据库属性
db2 update dbm cfg using federatedyes 
db2stop 
db2start 
********************************************************************************* 
2.编目节点
CATALOG TCPIP NODE db2_node REMOTE system42 SERVERdb2tcp42
where:db2_node is the name that you assign to thenode 
system42 is the host name of the system where the data sourceresides 
db2tcp42 is the service name or primary port number of the serverdatabase manager instance 
********************************************************************************* 
3.编目数据库 
CATALOG DATABASE DB2DB390 AS CLIENTS390 AT NODE DB2NODEAUTHENTICATION SERVER
where:DB2DB390 is the name of the remote database tocatalog 
CLIENTS390 is the alias for the remote database being cataloged. Ifyou do not specify an alias, the database manager uses the name ofthe remote database as thealias. 
DB2NODE is the name of the node that you previouslycataloged 
AUTHENTICATION SERVER specifies that authentication takes place onthe DB2 data source node 
********************************************************************************* 
4.创建wrapper 
db2 create wrapper drda 
********************************************************************************* 
5.创建server 
CREATE SERVER CRANDALL
TYPE DB2/ZOS
VERSION 7.1
WRAPPER DRDA
AUTHORIZATION "GERALD" 
PASSWORD drowssap
OPTIONS
(DBNAME 'CLIENTS390',
FOLD_ID 'U',
FOLD_PW 'U',
COLLATING_SEQUENCE 'Y')
where: Register a server definition to access a DB2 for z/OS? andOS/390?, Version 7.1 data source. CRANDALL is the name assigned tothe DB2 for z/OS and OS/390 server definition. DRDA is the name ofthe wrapper used to access this data source. In addition, specifythat: 
GERALD and drowssap are the authorization ID and password underwhich packages are bound at CRANDALL when this statement isprocessed. 
The alias for the DB2 for z/OS and OS/390 database that wasspecified with the CATALOG DATABASE statement isCLIENTS390. 
The authorization IDs and passwords under which CRANDALL can beaccessed are to be sent to CRANDALL inuppercase. 
CLIENTS390 and the federated database use the same collatingsequence.

6创建mapping 
CREATE USER MAPPING FOR ETL SERVERCRANDALL 
OPTIONS (REMOTE_AUTHID 'etl', REMOTE_PASSWORD'xxxxxx');
********************************************************************************* 
7创建nickname 
CREATE NICKNAME SCHEMA.TABLENAME FORSERVERNAME.SCHEMA.TABLENAME; 
********************************************************************************* 
相关参考:
db2 list node directory 
db2 list db directory 
DROP USER MAPPING FOR authorization_name SERVERserver_name 
DROP NICKNAME nickname
