有一台oracle 10g的监听莫名死掉，进行查看

select * from v$version

Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - 64bi

select status,count(*) from v$session group by status order by count(*) desc;

查看链接的session 情况

==在listener.ora 中添加

SUBSCRIBE_FOR_NODE_DOWN_EVENT_LISTENER=OFF

connect_timeout_listener=2

lsnrctl set log_status off

mv listener.log /tmp

lsnrctl set log_status on

[oracle@hongquan archivelog]$ lsnrctl

LSNRCTL> show inbound_connect_timeout

Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.32.8)(PORT=1521))(CONNECT_DATA=(SERVER=DEDICATED)(SID_NAME=hongquan)))

LISTENER parameter "inbound_connect_timeout" set to 60

The command completed successfully

LSNRCTL> SET INBOUND_CONNECT_TIMEOUT 2

LSNRCTL> set save_config_on_stop on #表示修改参数永久生效，否则只是临时生效

解决方案:

在Oracle Net Server tracing/logging中出现这个错误，请在sqlnet.ora中设置DIAG_ADR_ENABLED =OFF

在Listener component中出现这个错误，请在listener.ora中设置DIAG_ADR_ENABLED_ = OFF

sqlnet.ora:

SQLNET.INBOUND_CONNECT_TIMEOUT=180

listener.ora:

INBOUND_CONNECT_TIMEOUT_listener_name=120
