Try Clustering and VIPs

Use a clustering technology. Something like SunCluster or VeritasCluster. They are however what you can call a more advanced topic in Unix, but it will definitly give you the failover from A ----> B with full application uptime.

If clustering isnt your thing and all you have is tapes, then just restore the tapes to the new server and make system adjustements.

Another thing you can do is have a VIP created in your environment. Have all applications point to the VIP. Make sure both servers are up and running. One taking load and the other not. Then have a job created to change the DNS entry of the VIP to point to server B should there be a failure on A.

There are a lot of ways of doing this, implementing it has to do with the comfort level and SLA's that the applications require.

I hope that helps.

qmove(1B)								PBS								 qmove(1B)

NAME
qmove - move pbs batch job SYNOPSIS
qmove destination job_identifier ... DESCRIPTION
To move a job is to remove the job from the queue in which it resides and instantiate the job in another queue. The qmove command issues a Move Job batch request to the batch server that currently owns each job specified by job_identifier. A job in the Running , Transiting , or Exiting state cannot be moved. OPERANDS
The first operand is the new destinationfor queue @server queue@server See the PBS ERS section , "Destination Identifiers". If the destination operand describes only a queue, then qmove will move jobs into the queue of the specified name at the job's current server. If the destination operand describes only a batch server, then qmove will move jobs into the default queue at that batch server. If the destination operand describes both a queue and a batch server, then qmove will move the jobs into the specified queue at the speci- fied server. All following operands are job_identifiers which specify the jobs to be moved to the new destination. The qmove command accepts one or more job_identifier operands of the form: sequence_number[.server_name][@server] STANDARD ERROR
The qmove command will write a diagnostic messages to standard error for each error occurrence. EXIT STATUS
Upon successful processing of all the operands presented to the qmove command, the exit status will be a value of zero. If the qmove command fails to process any operand, the command exits with a value greater than zero. SEE ALSO
