Permit me start with the second question.
It would be easier to be more precise if it were pinned down to a
specific situation.Anyway .........
User errors vary widely ,It may not be feasible to pinpoint all the
different user errors.Depending on the rights a user has ,user errors
may span from deleting a the contents of a table to deleting
datafile(s).Solving user errors may range from typing rollback on
the command line to recreating the database or........
Oracle documentation may help .
TSPITR (Oracle 8 and above) Enables recovery of one or more non system
tablespaces to a point in time that is different than that of the
database.
If all the tables you want to recover are located in a single
tablespace
then a tablespace point in time recovery would be adequate.
1)Backup and restore to the new server(if it is configured the same as
the present one).
Install a database in the new server with all the existing schemas Do
a full database export/import
Edit the connection string of the java client to point to your new
server.
