Ora-01033?

This question appeared several times, Baidu did not find the answer, causing me to uninstall the database and reinstall it.

But this mistake was reported again the second time.

According to the Internet.

I can get in with sys. But yl users are not allowed to enter. It would be like reporting a mistake.

So I created another test user, and there was no problem logging in.

The solution that came to mind at that time was to delete the user and re-import the user's packet.

After leaving for a while, my colleague operated on the database. He said he could log in and did nothing.

So, the solution to this problem has yet to be determined. The cause remains to be determined.

Because the client is installed, there are two oci. I tried to overwrite the client oci to the 12c server installation directory. In this way, the oci path of pl\ sql can be unspecified. The problem was solved at that time. After a while, the database could not log in. Abnormal termination.

Baidu said that the dll file is a nonsense. I should have done this. To restore.

After the restore, the database can log in.

But it is not certain that the problem with ora-01033 is caused by doing this operation.
