使 Oracle 能同时访问多个SQL Server-3

已选择6行,用SQL Navigator或Toad看从SQL Server转移到ORACLE里的表的建表语句为:

CREATE TABLE stores 

("stor_id" CHAR(4) NOT NULL, 

"stor_name" VARCHAR2(40), 

"stor_address" VARCHAR2(40), 

"city" VARCHAR2(20), 

"state" CHAR(2), 

"zip" CHAR(5)) 

PCTFREE 10 

PCTUSED 40 

INITRANS 1 

MAXTRANS 255 

TABLESPACE users 

STORAGE ( 

INITIAL 131072 

NEXT 131072 

PCTINCREASE 0 

MINEXTENTS 1 

MAXEXTENTS 2147483645 

)

总结:

Windows下Oracle9i网关服务器在 $Oracle9i_HOMEtg4msqladmin目录下的initsqlserver_databaseid.ora。Windows下Oracle9i网关服务器listener.ora里面：

(SID_DESC= 

(SID_NAME=sqlserver_databaseid) 

(ORACLE_HOME=d:OracleOra92) 

(PROGRAM=tg4msql) 

)

UNIX或WINDOWS下ORACLE8I,ORACLE9I服务器tnsnames.ora里面：

northwind = 

(DESCRIPTION = 

(ADDRESS_LIST = 

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.2)(PORT = 1521)) 

) 

(CONNECT_DATA = 

(SID = sqlserver_databaseid) 

) 

(HS = sqlserver_databaseid) 

)

需要sqlserver_databaseid一致才行。
