[bdb-devel] sequence problem for more process

Hi list

I have problem about sequence with more process. For example

I have two process and first process got sequence key 1 and I want to second process to get sequence key 2 because first process got already key 1 but second process get sequence key 1 and both of process inserted data to database with sequence 1

when I want to get sequence value, altough creat sequence, open sequence, get sequence and close sequence every time, those processes got same sequence number.How to got different sequence key for example like this I want to:

process 1 sequence keys: 1,2 5 7 process 2 sequence keys: 3,4 6
