tnsping可以通说明tnsnames.ora写的没问题，但是怎么还回有连接问题呢？

由于是11G的RAC，listener不归oracle用户管，是grid用户管的。查了GI下listener相关，也没发现异常。

在metalink上找到一篇，ID 1069517.1相关的，开始检查

1. 用listener的owner用户检查rdbms_home目录下是否有权限

# ls -l /xxx/app/oracle/product/11.2.0.3/db/bin/oracle

-rwsr-s--x   1 oracle   oinstall 233186712 May 10 09:00 /xxx/app/oracle/product/11.2.0.3/db/bin/oracle

这项没有问题。

2. 查看该目录权限 是否是6751：

-rwsr-s--x  也没有问题，如果这里不是这样，请使用：

chmod 6751  /xxx/app/oracle/product/11.2.0.3/db/bin/oracle

修改。

3. 检查oracle软件目录的文件系统是否支持setuid/suid，或者是被设置成了nosetuid。我开始流汗了。。。。

# mount| grep /xxx

/xxx on /dev/md/dsk/d56 read/write/nosetuid/nodevices/intr/largefiles/logging/xattr/οnerrοr=panic/dev=1540038 on Fri May 11 23:22:40 2012

我靠，居然中招了，系统组的同事，我要吐槽！！！

@*((*&(*&(!(&$))%)*(&

发邮件，15分钟反馈，改好了，变成setuid了。问题解决。

# mount| grep /xxx

/xxx on /dev/md/dsk/d56 read/write/setuid/devices/intr/largefiles/logging/xattr/οnerrοr=panic/dev=1540038 on Tue Jun 12 07:43:59 2012
