Flashback enhancements

Oracle's new flashback feature available in Oracle version 10g is not supported in Replication Agent for Oracle. Because flashback is not supported, it requires that you disable the recycle bin:

To disable the recycle bin which was added in Oracle 10.2 (which requires sysdba privileges):
```
purge dba_recyclebin;
ALTER SYSTEM SET recyclebin = OFF;
```
To disable the recycle bin in Oracle 10.1, you must set the Oracle hidden property:
```
ALTER SYSTEM SET “_recyclebin”=FALSE SCOPE = BOTH;
```

In Oracle 10.2, to view the contents of the recycle bin:

select * from dba_recyclebin;

In Oracle 10.2, to view the current recycle bin configuration:

select value from v$parameter where name = “recyclebin”;
