数据库日志中Immediate Kill Session错误解决方法

环境:hp_unix + oracle 10.2.0.3 rac

客户一套rac数据库日志中节点1日志错误如下:
ALTER SYSTEM SET service_names='' SCOPE=MEMORY SID='ORCL1';
...
Immediate Kill Session#: 1606, Serial#: 23
Immediate Kill Session: sess: 0x447e141c0 OS pid: 21802
Immediate Kill Session#: 1607, Serial#: 25
Immediate Kill Session: sess: 0x446e27580 OS pid: 21751
Immediate Kill Session#: 1608, Serial#: 32
Immediate Kill Session: sess: 0x447e15670 OS pid: 21804
Immediate Kill Session#: 1610, Serial#: 56
Immediate Kill Session: sess: 0x447e16b20 OS pid: 20036
Immediate Kill Session#: 1611, Serial#: 21
Immediate Kill Session: sess: 0x446e29ee0 OS pid: 19893
...
ALTER SYSTEM SET service_names='ORCL' SCOPE=MEMORY SID='ORCL1';

从上面信息可以看出,连接在节点1上的会话全部被kill掉,这个时候查看操作系统日志

绑定在lan1公网的vip 地址发生漂移,导致节点1上的所有会话转移到节点2上,应用连接正常
但这时数据库日志不应该报这些错误,通过查metalink ID为730315.1

要解决这个报错信息,以下两种解决方法:
第一.升级到10.2.0.5

第二.修改service_name，不要和db_name名称相同。
