的口令文件,假如该文件不存在,则开始查找,orapw的口令文件。如果口令文件命名为orapw,多个数据库就可以共享。
再来看一下测试:
[oracle@jumper dbs]$ sqlplus "/ as sysdba"

建立orapw口令文件,此时可以打开数据库。
SQL> !
[oracle@jumper dbs]$ ls
hsjf initdw.ora inithsjf.ora init.ora lkHSJF orapwhsjf.bak spfilehsjf.ora
[oracle@jumper dbs]$ cp orapwhsjf.bak orapw

exit

很多人可能会产生有这样的疑问,多个Exclusive的数据库是否可以共享一个口令文件(orapw)呢?
继续回到试验中:
SQL> show parameter passwordNAME TYPE VALUE
------------------------------------ ----------- ---------------
remote_login_passwordfile string SHARED
[oracle@jumper dbs]$ strings orapw
