作者提出的题目是这样的：
一台测试的处事器，停电回复来后发明listener起不来，报错如下：
Listening on: (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=192.168.191.100)(PORT=1521)))
Error listening on: (ADDRESS=(PROTOCOL=ipc)(PARTIAL=yes)(QUEUESIZE=1))
No longer listening on: (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=192.168.191.100)(PORT=1521)))
TNS-12549: TNSperating system resource quota exceeded
TNS-12560: TNSrotocol adapter error
TNS-00519: Operating system resource quota exceeded
Linux Error: 28: No space left on device
对付这个提醒，一样平常的直觉反应是磁盘空间用完了，不外这个错误必定各人都能发明：
起首查察log文件，已经2G了，打开看看日记内里也没发明什么非常，以为日记是天然增添到这么大的，于是直接cat /dev/null>listener.log把日记清空。然后listener照旧起不来，如故报上面的错误。之后重启呆板，照旧不可，搜查磁盘空间也没有题目。
?
显然没这么简朴，早年的一些履历，当体系信号量不敷时也也许导致这类错误提醒。
不外作者最后发明的题目是inode耗尽。
在Linux上，我们可以用df -i来查察inode的分派环境：
[
[email?protected] elog]$ df -i
Filesystem Inodes IUsed IFree IUse% Mounted on
/dev/hda3 131616 25376 106240 20% /
/dev/hda1 66264 35 66229 1% /boot
/dev/hda5 1048576 37166 1011410 4% /data1
/dev/hda9 294336 6020 288316 3% /home
/dev/hda6 1048576 20467 1028109 2% /opt
none 64193 1 64192 1% /dev/shm
/dev/hda8 524288 87362 436926 17% /usr
/dev/hda7 524288 1598 522690 1% /var
?
假如inode耗尽，则体系大将不能建设文件。监听器就也许无法启动。
作者其时耗尽的/var下的inode，那么Oracle监听器是否必要行使var下的空间呢？
我们看一下测试：
[
[email?protected] tmp]$ strace -o lsnrctl.log lsnrctl start

搜查一下跟踪文件：
[
[email?protected] tmp]$ grep var lsnrctl.log?
execve("/opt/oracle/product/9.2.0/bin/lsnrctl",["lsnrctl","start"],[/* 33 vars */]) = 0
connect(4,{sa_family=AF_UNIX,path="/var/run/.nscd_socket"},110) = -1 ENOENT (No such file or directory)

access("/var/tmp/.oracle/sEXTPROC",F_OK) = 0
connect(4,path="/var/tmp/.oracle/sEXTPROC"},110) = 0
