Oracle19c rac两节点实例test，在节点1查看监听状态没有test1，但在节点2可以看到test2
两节点上还有实例abc，xyz的监听都正常，唯独这个节点1上test1实例没有被监听。
奇怪。
检查集群状态，貌似正常，都是online的：
尝试登录test1执行alter system register;
lsnrctl status查看还是没有注册test1。
然检查两个节点的local_listener参数，发现了问题：
节点1上显示的是-oraagent-dummy-而节点2上显示的是正常的vip信息
节点2如下：
确认ping 节点1-vip正常。
登录test1执行操作：
sqlplus / as sysdba
alter system set local_listener='(ADDRESS=(PROTOCOL=TCP)(HOST=节点1-vip)(PORT=1521))' scope=both sid='test1';
show parameter local_listener;--确认修改
lsnrctl status--确认test1注册成功。
想起之前最近节点1由于异常reboot重启过，所以导致local_listener信息丢失。
如果上述无法解决，则可能需要重启节点1的监听服务：
如果还不行就得重启下节点1监听：
srvctl stop listener -n rac1
lsnrctl status
srvctl start listener -n rac1
lsnrctl status
参考状态检查：
