  • Thread-topic: Question about jdbc connection pool

I am pretty sure that maps to the ServerSocket’s backlog: “requested maximum length of the queue of incoming connections”

Off the top of my head, not sure. It’s probably specified in java monitor help. But it has nothing to do with database connections AFAIK.

Thanks again. What is the “Connection pool size” in the JavaMonitor then? Something else?

Yes, one connection per application instance is the default.

Thanks Ramsey. Does that mean there is only 1 database connection shared by all end-users of an app? So if a user hits a query that runs for 3+ seconds all other application users are stuck waiting for that query to complete?

The ObjectStoreCoordinator opens one connection which everything shares by default. If you want multiple connections, you have to create multiple OSCs. There’s an OSC pool built into Wonder, but it leaks memory.

Hello,

How does one set the jdbc connection pool size? Is there a default if this isn’t specifically set?

 

Thanks,
