Navneet, what version of Oracle are you using? I haven't pulled the manual but looking at v$parameter my query shows me that the parameter cannot be dynamically changed at the SESSION level, but that a change at the SYSTEM level has immediate effect.

Now I am facing one more problem, in our production server we have log_archive_dest parameter. Oracle docs says we can's change it dynamically, so we can't have log_archive_dest_n. Any workaround to this? Regards, Navneet On 9/22/05, Howard Latham <howard.latham@xxxxxxxxxx> wrote: Do you really mean different hardware as in DIFFERENT or same or similar hardware? Howard A.

We will get RMAN backup of the database. And we will have access to archive logs generated during shipping/restoration(It would be some seven days archive logs). What are the options we have got to restore the databases and bring it uptodate by applying archives. Dataguard is a solution here? It's 9i on Solaris 9. Thanks in Advance, Navneet
