Of course, maybe it is a limited reason.
A few days ago, my own database suddenly had a problem. My Scott user did not build the permissions of the table, and later found that all ordinary users did not have DDL / DML permissions, once the execution report 1031 error.
I really didn't do anything, I want to see how the Oracle's high people will solve, of course, because I have built a use, waiting for Oracle to give me Support, because I have known that Oracle's people are too powerful.
ITAR is applying for ITAR on the 25th, and muthukumar is very active to open OWC. I have a remote operation to see him, no fruit, he will get off work. I was dragged in a few days.
On the 26nd, he suspected that there is a problem with CDC, OK, prohibiting CDC, and it is a problem.
On the 27th, I didn't care for me in a long time, requiring Startup Migrate, Then Catalog / Catproc, complete, the same.
On the 28th, it is recommended to rebuild the database.
In fact, I have built a new database in front, just want to see how they will solve this problem, haha, I didn't expect. . . .
From here I think, if there is a lot of data, it is not enough to have physical backup, you must come out to you, it is not very trouble, it should still have a way.
