DB2建立聯邦資料庫

聯邦資料庫配置步驟:
db2 update dbm cfg using federated yes #引數配置
db2 catalog node #編目節點
db2 catalog database #編碼遠端資料庫
db2 connect to db #連線本地資料庫
db2 create wrapper drda #建立wrapper
db2 create server　　 #建立伺服器
db2 create user mapping　#建立使用者mapping
db2 create nickname　 #建立遠端資料庫物件nickname
*********************************************************************************
1.設定資料庫屬性
db2 update dbm cfg using federated yes
db2stop
db2start
*********************************************************************************
2.編目節點
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.編目資料庫
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.建立wrapper
db2 create wrapper drda
*********************************************************************************
5.建立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建立mapping
CREATE USER MAPPING FOR ETL SERVER CRANDALL
OPTIONS (REMOTE_AUTHID 'etl', REMOTE_PASSWORD 'xxxxxx');
*********************************************************************************
7建立nickname
CREATE NICKNAME SCHEMA.TABLENAME FOR SERVERNAME.SCHEMA.TABLENAME;
*********************************************************************************
