I'd open a PMR and get instructions for a trace. Do the trace and send to IBM for analysis.
Poor performance could be any number of things. The 'overload' might be a DOS, excessive retries, or a configuration issue. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Horne, Jim - James S Sent: Monday, April 18, 2011 9:39 AM To: [email protected] Subject: When is an OSA card too busy? This is a stupid question but we need to analyze the use on one of our OSA CHPIDs. Anyone who actually know anything about it is out of the office so it has fallen to me to look into it. I can tell it's not as simple as just Bus busy or Channel busy, or Read bytes and write bytes but I'm looking for a resource that can give me an idea of what combination of factors can lead you to think that an OSA may be overloaded.
