[20170329]给oracle启动加入baner.txt
--//测试一下给oracle 启动加入一个banner,没有什么意思,仅仅为了玩.
1.环境:
SYS@book> @ &r/ver1
PORT_STRING VERSION BANNER
------------------------------ -------------- --------------------------------------------------------------------------------
x86_64/Linux 2.4.xx 11.2.0.4.0 Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production
2.修改sqlnet.ora文件加入:
SEC_USER_AUDIT_ACTION_BANNER=/u01/app/oracle/product/11.2.0.4/dbhome_1/network/admin/banner.txt
--//建立banner.txt文件:
$ cat /u01/app/oracle/product/11.2.0.4/dbhome_1/network/admin/banner.txt
welcome test oracle!!
3.测试:
--//重启启动数据库:
SYS@book> startup nomount
welcome test oracle!!
ORACLE instance started.

Database Buffers 427819008 bytes
Redo Buffers 7524352 bytes
--//注意看前面提示!!继续:
SYS@book> alter database mount ;
Database altered.
SYS@book> alter database mount ;
Database altered.
SYS@book> alter database open ;
Database altered.
--//很奇怪如果我直接startup:
SYS@book> startup
welcome test oracle!!

--//奇怪并不是每次登录读这个文件.
# lsof | grep -i banner
--//也没有那个进程打开这个文件,做一个跟踪:
$ strace -o /tmp/aa.txt -f sqlplus scott/book

37816 write(1, "welcome test oracle!!\n", 22) = 22

--//跟踪文件里面也没有打开banner.txt文件的句柄.重启监听看看:
