Paul,
By doing "alter database activate standby database;", Oracle does a
resetlogs.
It means that I have to recreate a fresh standby database.
There is no Graceful switch ? I found docs for Oracle8.1.7, create new
controlfile file, send redo log files, ...
My question is :
With Oracle 9.2, Standard Edition, we managing the standby database the same
way then the standby with Oracle 8.1.7
Thanks
Luc
