RAC各个节点按如下配置：

[oracle@ora19crac1~]$vi$ORACLE_HOME/network/admin/listener.oraLISTENER=(DESCRIPTION_LIST=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=scan-ora19cracdb)(PORT=1521))(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC1521))))SID_LIST_LISTENER=(SID_LIST=(SID_DESC=(GLOBAL_DBNAME=woo_DGMGRL)(ORACLE_HOME=/u01/app/oracle/product/19.3.0/dbhome_1)(SID_NAME=woo)))[oracle@ora19crac2~]$cat$ORACLE_HOME/network/admin/listener.oraLISTENER=(DESCRIPTION_LIST=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=scan-ora19cracdb)(PORT=1521))(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC1521))))SID_LIST_LISTENER=(SID_LIST=(SID_DESC=(GLOBAL_DBNAME=woo_DGMGRL)(ORACLE_HOME=/u01/app/oracle/product/19.3.0/dbhome_1)(SID_NAME=woo)))

单实例节点配置：

[oracle@ora19cadg~]$cat$ORACLE_HOME/network/admin/listener.oraLISTENER=(DESCRIPTION_LIST=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=ora19cadg)(PORT=1521))(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC1521))))SID_LIST_LISTENER=(SID_LIST=(SID_DESC=(GLOBAL_DBNAME=woo_DGMGRL)(ORACLE_HOME=/u01/app/oracle/product/19.3.0/dbhome_1)(SID_NAME=woo)))2.2. 配置TNSNAME.ora网络连接文件

所有节点配置如下:

[oracle@ora19crac1~]$cat$ORACLE_HOME/network/admin/tnsnames.ora#tnsnames.oraNetworkConfigurationFile:/u01/app/oracle/product/19.3.0/dbhome_1/network/admin/tnsnames.ora#GeneratedbyOracleconfigurationtools.WOO=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=scan-ora19cracdb)(PORT=1521))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=woo)))WOOSTY=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.84.99)(PORT=1521))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=woosty)(UR=A)))2.3. 所有节点在hosts中添加如下解析
