Re: Caught Exception Object Expected - 7.6.04 Mid-tier - Update
Jesus, We once had a problem with our load balanced scenario when using short vs long names. It turned out that the issue was with DNS Domain Suffix Search Order. Some of our machines were in order Server.domain1.com Server.domain2.com And others were in Server.domain2.com Server.domain1.com Order, where the user was specifying 'server'.this caused some clients to properly hit the correct server, and others, not. So being this is a problem on the mid-tier servers, I would recommend checking a ping of the short name and long name from all of your web servers and verify that all of them hit the correct IP...you may be surprised. -Original Message- From: Action Request System discussion list(ARSList) [mailto:arslist@ARSLIST.ORG] On Behalf Of Ortega, Jesus A Sent: Monday, August 13, 2012 3:22 PM To: arslist@ARSLIST.ORG Subject: Re: Caught Exception Object Expected - 7.6.04 Mid-tier - Update I have an update on the Caught Exception issue.
