Hi Everyone, I have a java class that could run several threads (each thread is calling the same RPG program via ProgramCall). Although all the thread are running to process several transactions, but we notice a delay between the RPG's execution. It's like the jobs are waiting in a queue. Is it because on the AS/400 the thread are maybe running on jobq, or there is a maximum of thread that can run at same time ? Regards Mamadou
