下面来看db server本机登陆sqlplus 有什么现象:

[oracle@rhel63single ~]$ sqlplus  / as sysdb

SQL*Plus: Release 11.2.0.4.0 Production on Thu Jan 8 21:04:16 2015

Copyright (c) 1982, 2013, Oracle.  All rights reserved.

ERROR:
ORA-12547: TNS:lost contact


Enter user-name: 

 

 

3分钟左右,才报上述错误.
而从oracle db client(pl/sql developer)连接该db,报:

 ORA-12537: TNS: connection closed

 

此时,trace目录也是进不去的:

[oracle@rhel63single test]$ cd trace
-bash: cd: trace: Permission denied


解决该问题的方法其实很简单:

[oracle@rhel63single test]$ chmod u+x trace
