title: Generate Primary key without using Database
body: <p>I came across a question recently that was for "Generating primary key in a clustered environment of 5 App-Servers - [OAS Version 10] without using database".</p>
  
  <p>Usually we generate PK by a DB sequence, or storing the values in a database table and then using a SP to generate the new PK value...However current requirement is to generate primary key for my application without referencing the database using JDK 1.4. </p>
  
  <p>Need expert's help to arrive on better ways to handle this.</p>
  
  <p>Thanks, </p>
