You know how many JVMs on which your application is deployed. Say you have 4 JVMS
This is how you can divide your work among multiple JVMs.
1. Java program running in each JVM will generate a random no say 51, 40, 33, 42 (4 JVMs so 4 random nos).
2. Each program will enter his random no in DB and wait till all four enters there random no.
3. After all the four random nos are entered in DB the program running on JVM with the least no (33 i.e. JVM 3) will become master and will divide the work and update the DB with the division of work (division of work mean which JVM will process which set of data).
4. Once the master JVM enters the plan All JVM can follow the plan.
Please let me know if this solution fits your problem.
