-
Stop the propagation.
-
Ensure that the source queue is empty.
-
Ensure that the destination queue is empty and has no unapplied, spilled messages before you drop the propagation.
-
Re-create the propagation with the
queue_to_queueparameter set toTRUEin the creation procedure.
aix5.3系统上的oracle 10.2.0.3 RAC，连接数据库的时候经常报如下错误：
| ORA-12545: Connect failed because target host or object does not exist |
这个问题可以通过设置rac数据库各个节点的local_listener参数来解决，有两种方式：
方式1
在RAC的每个节点上编辑$ORACLE_HOME/network/admin/tnsnames.ora，增加| local_listener_rac= (ADDRESS_LIST= (ADDRESS=(PROTOCOL=tcp)(HOST=<vip>)(PORT=1521)) ) |
在rac的任意一个节点上修改数据库参数，设置local_listener为local_listener_rac
| $ sqlplus / as sysdba SQL> alter system set local_listener='local_listener_rac' scope=spfile; |
重新启动各个节点上的数据库实例
方式2
也可以按照metallink上id为 364855.1的文档使用如下方法修改在rac的每个节点上执行如下语句设置local_listener参数
| sql>alter system set LOCAL_LISTENER="(ADDRESS=(PROTOCOL=TCP)(HOST=<VIP_address>)(PORT=1521))" scope=both sid='instance_name'; |
其中 <VIP_address>对应每个节点的vip地址；
instance_name对应当前节点的实例名，如rac1、rac2等，即每次只修改当前实例的参数
