oracle crs监听状态为offline处理过程

今天帮客户去巡查一个数据库时,用crs_stat 查看状态,发现web2节点监听状态为offline
% crs_stat -t
Name Type Target State Host

ora....01.inst application ONLINE ONLINE web1
ora....02.inst application ONLINE ONLINE web2

通过用以下命令去启动,启动失败,hang在那里
srvctl start listener web2
sqlplus 连接也是挂起
% sqlplus system/abcdefg@2000

查找监听进程,进程存在
% ps -ef|grep tns
oracle 266256 1 0 Jul 16 - 7:37 /oracle/10.2/db_1/bin/tnslsnr LISTENER_WEB2 -inherit
oracle 512324 409744 0 15:28:53 pts/2 0:00 grep tns

看来监听进程是挂死了,外面连接也无法进入,采取的解决方法 kill掉监听进程
kill 266256
再启动监听进程 成功
crs监听状态 正常
% crs_stat -t
