Powerbuilder 11: Transaction pooling

I have PowerBuilder 11 classic application (2-Tier application) and a COM component build using PowerBuilder 9 that connects to the database directly (uid/pwd harcoded inside the application) through transaction objects. I have requirement to eliminate the hardcoded part and hide the connection information from developers. Is there a way to connect to the database like n-tier applications? Any ideas?

Thanks,

Senthil
