About JAS Server JDBj Pooled Database Connections Parameter

Hello,

I am trying to integrate invoice data from an external system via REST APIs to JDE, but hitting max JAS Server JDBj Pooled Database Connections value because of the connections from JAS to DB. I set that parameter value as 300, but it seems that is not enough if the number of invoices to be integrated is remarkably big. My question comes up at that point. How can I optimize the value of that parameter?

Thanks in advance.
