Prabhakar,

You can do this in a batch, if you implement the Database.Stateful interface.  That being said, if you're only running through 6000 records, a simple Apex class that does a SOQL query and sums up the values should be sufficient.

For the batch scenario, Salesforce docs has an example of exactly what you're looking for here: http://www.salesforce.com/us/developer/docs/apexcode/Content/apex_batch_interface.htm (See the Database.Stateful example)
