某现场有两个实例，且客户要求两个实例使用不同的端口，但是grid管理下的监听默认只能一个端口，可以通过以下方式解决

oracle下：

srvctl add listener -l listener_cc -p 1522 -o $ORACLE_HOME

srvctl add listener -l listener_rb -p 1523 -o $ORACLE_HOME

srvctl start listener_cc

srvctl start listener_rb

起来后，$ORACLE_HOME/network/admin下的listener.ora自动生成以下信息

cat /oracle/product/19c/network/admin/listener.ora

LISTENER_RB=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER_RB)))) # line added by Agent

LISTENER_CC=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER_CC)))) # line added by Agent

ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER_CC=ON # line added by Agent

VALID_NODE_CHECKING_REGISTRATION_LISTENER_CC=SUBNET # line added by Agent

ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER_RB=ON # line added by Agent

VALID_NODE_CHECKING_REGISTRATION_LISTENER_RB=SUBNET # line added by Agent

然后修改cc和rb实例的local_listener如：

alter system set local_listener ='(ADDRESS=(PROTOCOL=TCP)(HOST=10.10.236.98)(PORT=1522))';

即可

如果需要配置静态监听，可以在$ORACLE_HOME/network/admin下的listener.ora添加：

SID_LIST_LISTENER_CC =

(SID_LIST =

(SID_DESC =

(GLOBAL_DBNAME =cc)

(ORACLE_HOME = /oracle/product/19c)

(SID_NAME = cc)

)

)

SID_LIST_LISTENER_RB =

(SID_LIST =

(SID_DESC =

(GLOBAL_DBNAME =rb)

(ORACLE_HOME = /oracle/product/19c)

(SID_NAME = rb)

)

)

检查监听状态：

lsnrctl status listener_cc
