Today , i'm very sad.
This morning, when i went at office, I saw that backup didn't work this night (since 3 days). When I search why it didn't work in the log file, I read in it an error ora-01187 and ora-01110. They mean that a datafile called TOTO_TEMP2.ORA failed verification tests.
But unfortunatelly, I don't find the reason of this problem.
The files is on the disk, at the good folder, with the good name.
Can anyone help me.
Can I create a new tablespace which could replace this one. If yes, could you explain me risks there are to move users from one tablespace to the new tablespace. How can I drop the "bad tablespace" ?
