Recently, my article has been very popular. I just want to summarize my knowledge from Marco Polo and send it to my blog. But I didn't expect that an article was first published nine times in the morning... If you really think my article is bad, please tell me the reason. Thank you very much.
This week, Marco talked about Linux kernel compilation and Linux kernel modules, which are easy to understand. So I will share my learning achievements with you. First of all, this is just a simple compila
factors:
1. The remote_login_passwordfile parameter in the parameter file, which has the following three values:
NONE: indicates that the Oracle system does not use the password file. users with the SYS permission can log on to the database through OS authentication.
EXCLUSIVE: Only one database instance can use this password file. Only the password file under this setting can contain user information except INTERNAL/
When you log on to the database using the default Oracle SQL plus (for example,), you can use the System user's default password manager to log on to the database.However, if you enter the user SYS and the default password change_on_install, you cannot log on.The following error is reported:Error:

Solution to the blue screen prompt error code atikmpag. sys in win7
One of the common failures is the blue screen phenomenon in win7. I believe many users have encountered it. Generally, we solve the problem based on the blue screen error code. Recently, a user said that the Windows 7 system encountered a blue screen error code atikmpag. sys. How can this problem be solved? There are many reasons for the co
