《網絡部分介紹》
oracle數據庫服務器是客戶端
windows上
建兩個數據庫orcl用zhs16gpk和utforcl用al32utf8
服務oracleServiceORCL和oracleServiceutforcl開啓
cmd
oradim 幫助
lsnrctl service
1、配置監聽
2、配置別名
3、配置連接時故障轉移
4、控制監聽器
tnsping 測試網絡
linux客戶端或者服務器的網絡配置文件都在這個目錄
/u01/app/oracle/product/11.2.0/grid/network/admin
crs_stat -p | grep lsnr
NAME=ora.LISTENER.lsnr
crsctl stop res ora.LISTENER.lsnr
如果換端口改這個配置文件
/u01/app/oracle/product/11.2.0/grid/network/admin/listener.ora
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.55)(PORT = 15210))
)
)
然後複製到/u01/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora
crsctl start res ora.LISTENER.lsnr 重啓監聽
lsnrctl services 查看監聽
SQL> show parameter local_lis
SQL> alter system set local_listener="FOR15210";
lsnrctl services 查看監聽
需要把這個文件拷貝到grid目錄下，這個目錄是dbca創建的默認路徑，單用戶雙HOME
/u01/app/oracle/product/11.2.0/dbhome_1/network/admin/tnsnames.ora
進行修改後在拷貝！
FOR15210 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.55)(PORT = 15210))
)
lsnrctl services
