Oracle 11g 여러 sqlserver 연결
공식 문서 참조
1.tg 설정1 initdg4msql.ora 여러 개의 Sqlserver 에 연결 하려 면 여러 개의 initdg4msql.ora 파일 을 설정 해 야 합 니 다.
[sql] view plaincopy
D:appAdministratorproduct11.2.0tg_1dg4msqladmin
copy initdg4msql.ora initdg4msql1.ora
copy initdg4msql.ora initdg4msql2.ora
Change the value of the HS_FDS_CONNECT_INFO parameter in the new files.
For initdg4msql1.ora, enter the following:
HS_FDS_CONNECT_INFO=192.168.1.225//DB1 HS_FDS_TRACE_LEVEL=OFF HS_FDS_RECOVERY_ACCOUNT=RECOVER HS_FDS_RECOVERY_PWD=RECOVER For initdg4msql2.ora, enter the following:
HS_FDS_CONNECT_INFO=192.168.1.225//DB2 HS_FDS_TRACE_LEVEL=OFF HS_FDS_RECOVERY_ACCOUNT=RECOVER HS_FDS_RECOVERY_PWD=RECOVER
2.tg 설정1 LISTENER

6.Create DB Link
[sql] view plaincopyCREATE PUBLIC DATABASE LINK MSQL1 CONNECT TO "sa" IDENTIFIED BY "passwd1" USING 'dg4msql1'; [sql] view plaincopyCREATE PUBLIC DATABASE LINK MSQL2 CONNECT TO "sa" IDENTIFIED BY "passwd2" USING 'dg4msql2'; 7.TEST Connection
[sql] view plaincopySQL> SELECT * FROM ALL_USERS@MSQL1; SQL> SELECT * FROM ALL_USERS@MSQL2;
