So an update to my quest of knowledge... https://en.wikipedia.org/wiki/Unix_domain_socket and http://www.thomasstover.com/uds.html
The bottom line is this form of "socket" is integral for any process to process communication not just networking, amy I going down the right path? ________________________________________ From: IBM Mainframe Discussion List <[email protected]> on behalf of Tracy Adams <[email protected]> Sent: Thursday, April 14, 2016 9:38 AM To: [email protected] Subject: OMVS (TCPIP) internals question I am trying to understand the function of TCPIP and its "max sockets". We are experiencing a problem that happens infrequently where our CICS application closing down the DataPower port with an error that indicates max sockets has been reached. IBM support has confirmed this in a dump. They say our max and current values are at 65,535 when the dump was initiated and to increase our maxsockets setting in BPXPRMxx. We are set at the default of 64000. Its maximum value is 16 million. This parameter is in the "network" definition of a "a single sockets file system". What I am grappling with is what is a "single sockets file system" and how the heck can we be hitting 65k units of anything? We are not that big! (so I think) So who and what consumes all these entries in this single socket file system? How can I monitor this? Netstat shows active connections between 700 - 900 so I don't believe this is the right spot to be looking. Quick explanations would be great, recommendations on readings that will clarify would be awesome as well.
