/var/tmp/.oracle目录权限被修改导致listener启动失败

在系统里装了weblogic之后，把/var目录下的一些权限改了，导致启动listener失败：

-bash-3.00$ lsnrctl start

网上 查了一下，与/var/tmp/下的隐藏目录.oracle权限有关：

 

[root@localhost tmp]# cd /var/tmp

[root@localhost tmp]# ls -ltra

total 24

drwxr-xr-x  19 root root 4096 Jun  4 09:45 ..

drwxr-xr-x   2 root root 4096 Jun 14 06:57 .oracle

drwxr-xr-x   3 root root 4096 Jul 17 19:50 .

 

将其属主改为oracle:dba

 

[root@localhost tmp]# chown -R oracle:dba .oracle

[root@localhost tmp]# ls -ltra

total 24

drwxr-xr-x  19 root   root 4096 Jun  4 09:45 ..

drwxr-xr-x   2 oracle dba  4096 Jun 14 06:57 .oracle

drwxr-xr-x   3 root   root 4096 Jul 17 19:50 .

 

再次启动listener，启动成功：

 

-bash-3.00$ lsnrctl start

检查.oracle目录的内容，发现如下内容：

 

[root@localhost .oracle]# ls -ltr

total 12

srwxrwxrwx  1 oracle dba 0 Jul 27 23:46 sEXTPROC0

srwxrwxrwx  1 oracle dba 0 Jul 27 23:46 s#9902.2

srwxrwxrwx  1 oracle dba 0 Jul 27 23:46 s#9902.1

 

可以推断当执行lsnrctl start命令时，需要往/var/tmp/.oracle里面写入这些临时文件，当该目录权限被修改后，写入文件失败，最终导致listener启动失败。
