problem statement: Optimizing database management ...instance[s]  ....automation

                            backup of  database files ...termed database backup

                            backup of  instance ....termed instance backup

                            synchronization of data-files or log play in distributed databases.

                            replication of  data ....also termable as replication of instances
                                       ....log-shipping(ftp/rcopy/nfs(source server) !! sychronization of folders (cachefs ..at remote-replication or target server))

                           find command from operating system parlance (identify ...files to be acted upon based on various attributes 
                           of the files , and the -exec option of the find command)


Opportunity a):  Given that most database's and their instances ...need to be identified and authenticated with
                       a operating system user.

                   scripts ...that fire or executed upon user-logon and log-off  ...make a ideal proposition (while some operating
                   systems offer additional or extra eventing that can be used ...in the context of automation) ...to include above activities.

                  By having operating system users repository stored in  active-directory or nis or nisplus or ldap integrated databases
                  ....management of multiple (optionally or also remote instances) instances can be made less hackle free or painless
                  by using same userid across the instances ...and generic scripts that work across instances ...by using common
                  or identical naming schema for instances or using-substitution-variables i.e. dynamic-values that can be picked
                  up by the scripts at the point of run-time or execution-time.


Opportunity b): Apart from replication of instances ...in some contexts and scenarios ...

                     given that most  [O]RDBMS managment ...consoles can be pointed or support management of multiple database instances....

                     ....where given sufficient bandwidth between remote sites and the local site (example ...banking ...tele-communications)
                     ....nfs shared remoted  instances (complete set of files that comprise a instance) ...can be managed locally (backup of data 
                     ...given that most db's provide integrity checks on such db images,...etc)
               
                                
 Note: The above problem statement having been encountered in various scenarios and detailed in various 'Proof of concepts' as mentioned in 
        
       http://uk.geocities.com/ravivenkatus/projects.pdf
       http://ravishankarkv.tripod.com/projects.pdf
        ....apply appropriate 'use-case' modeling, rationalize and arrive at a workable and feasible 
        solution both commercially and techinically viable.
