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 user mapping #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 federated yes
db2stop
db2start
*********************************************************************************
2.编目节点
CATALOG TCPIP NODE db2_node REMOTE system42 SERVER db2tcp42
where:db2_node is the name that you assign to the node
system42 is the host name of the system where the data source resides
db2tcp42 is the service name or primary port number of the server database manager instance
*********************************************************************************
3.编目数据库
CATALOG DATABASE DB2DB390 AS CLIENTS390 AT NODE DB2NODE AUTHENTICATION SERVER
where:DB2DB390 is the name of the remote database to catalog
CLIENTS390 is the alias for the remote database being cataloged. If you do not specify an alias, the database manager uses the name of the remote database as the alias.
DB2NODE is the name of the node that you previously cataloged
AUTHENTICATION SERVER specifies that authentication takes place on the 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? and OS/390?, Version 7.1 data source. CRANDALL is the name assigned to the DB2 for z/OS and OS/390 server definition. DRDA is the name of the wrapper used to access this data source. In addition, specify that:
GERALD and drowssap are the authorization ID and password under which packages are bound at CRANDALL when this statement is processed.
The alias for the DB2 for z/OS and OS/390 database that was specified with the CATALOG DATABASE statement is CLIENTS390.
The authorization IDs and passwords under which CRANDALL can be accessed are to be sent to CRANDALL in uppercase.
CLIENTS390 and the federated database use the same collating sequence.

6创建mapping
CREATE USER MAPPING FOR ETL SERVER CRANDALL
OPTIONS (REMOTE_AUTHID 'etl', REMOTE_PASSWORD 'xxxxxx');
*********************************************************************************
7创建nickname
CREATE NICKNAME SCHEMA.TABLENAME FOR SERVERNAME.SCHEMA.TABLENAME;
*********************************************************************************
