Re: Multi-threaded server application and Informix

}From: Jimmy Hui <jhui@newbridge.com> }Date: Thu, 03 Jul 1997 16:07:26 -0700 }X-Informix-List-Id: <news.40052> } }I created a multi-threaded server application, within which I used ESQL }statement to try to connect to the informix database. However, it }consistently complaint about the failure to connect to the database }server. On the other hand, if I had the same application compiled as a }non-threaded process, everything worked fine. } }Question: Do I need any configuration modifications to create a }multi-threaded server application?? } }I used VisiBroker for C++ to generate the server application, as well as }Informix Online Database Server Ver. 7.1 as the database server. Unless you know otherwise, 7.1x ESQL/C is not multi-threaded and cannot be used safely in a multi-threaded program. You need to use 7.2x ESQL/C to get a thread-safe implementation, and that uses DCE threads (which are a pre-cursor to Posix Threads.
