[oracle@ixyp04dbadm01 ~]$ telnet 192.168.10.80 7839
 -bash: telnet: command not found
 [oracle@ixyp04dbadm01 ~]$ curl -v telnet://192.168.10.80:7839

Because the Reverse utility only backs out changes, a test database can be restored in a matter of minutes, much more efficiently than a complete database restore, which can take hours. • To reverse errors caused by corrupt data or accidental deletions. For example, if an UPDATE or DELETE command is issued without a WHERE clause, the Reverse utility reverses the operation. 2.What needs to do for using the Reverse utility • Run Extract to extract the before data. • Run the Reverse utility to perform the reversal of the transactions. • Run Replicat to apply the restored data to the target database. 3.How the Reverse utility reverses the forward operations Reversing the ordering of database operations in an extract file, a series of extract
