I'm trying to find an application error: in my app log, I found an "ORA-1401 inserted value too large for column".
So I set the following:
svrmgrl> alter system set events '1401 trace name errorstack level <#level>'
I tried the same command with level 1, 4, 8 and 12, but no .trc file was generated. The curious thing, is that the command worked properly with "alter session...".
Does anybody has this problem.
