Hi! Gurus, I implemented a synchronized counter (for example Order ID) using Entity bean and use exclusive concurrency control perperty in WL to ganrantee that only one transacation is reading/writing that bean at one time point, so that the generated order id will not duplicate. However, I found it is a bottleneck. So what is the better design to improve the performance? Or is there other way to generate non-duplicate ID strings?
