修改scan监听器默认端口号

环境:
OS:Red Hat Linux As5
DB:11.2.0.1

通常情况下我们创建好scan监听器后,默认的都是使用1521端口后,但是因某种原因需要修改端口号,可以采用如下步骤实施.

1.停掉scan
[root@node1 ~]$srvctl stop scan_listener

 

2.修改端口
[oracle@node1 ~]$ srvctl modify scan_listener -p 1530
Exception in thread "main" java.lang.NullPointerException
        at oracle.cluster.impl.scan.ScanFactoryImpl.modifyScanListener(ScanFactoryImpl.java:937)
        at oracle.cluster.scan.ScanFactory.modifyScanListener(ScanFactory.java:417)
        at oracle.ops.opsctl.ModifyAction.executeSCANListener(ModifyAction.java:1349)
        at oracle.ops.opsctl.Action.execute(Action.java:291)
        at oracle.ops.opsctl.OPSCTLDriver.execute(OPSCTLDriver.java:280)
        at oracle.ops.opsctl.OPSCTLDriver.main(OPSCTLDriver.java:136)

这里很奇怪在grid用户下执行报错误 ,切换到root用户下执行
[root@node1 ~]# /u01/app/grid/11.2.0/bin/srvctl modify scan_listener -p 1530

3.修改数据库参数remote_listener
SQL> show parameters remote_listener

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
remote_listener                      string      racscan:1521
SQL> alter system set remote_listener='racscan:1530' scope=both sid='*';

 

4.重新启动scan
[grid@node1 ~]$ srvctl start scan_listener
[grid@node1 ~]$ srvctl status scan_listener
SCAN Listener LISTENER_SCAN1 is enabled
SCAN listener LISTENER_SCAN1 is running on node node1
[grid@node1 ~]$ srvctl config scan_listener
SCAN Listener LISTENER_SCAN1 exists. Port: TCP:1530
