Today, perform a export (old system, Oracle Version 9.2), of course, it is out of support, I have received this warning. It is a classical or typical error.
Whe you run execute the older exp
exp userid=X file=x.dat log=x.log owner=x buffer=1048576000
You can received one or several warnings like this
. . exporting table STATS$UNDOSTAT^C
EXP-00091 Exporting Questionable Statistic
. . exporting table STATS$WAITSTAT
There a two easy ways to solve this.
- export NLS_LANG=AMERICAN_AMERICA.WE8ISO8859P1 The character set and lenguage is depend on your system. It is important OS, in this case is a Solaris 10, because this variable is setting at level operating system.
- exp userid=X file=x.dat log=x.log owner=x buffer=1048576000 statistics=none In this case have executed exp with statistics parameter
