This Site Careers Other all forums Forum: Tomcat Apache tomcat 503 error. Aman Kaur Greenhorn Posts: 9 posted 8 years ago Hi folks! We have a Apache tomcat load balanced configuration. We are doing some performance https://coderanch.com/t/87917/Tomcat/Apache-tomcat-error testing before moving to Production. This is the error we get while testing: java.io.IOException: Server returned HTTP response code: 503 for URL: http://nte cmst1:80/drs/drs?type=PortalDocumentListByMRN&userId=nurse1&mrn=1194826 at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLCon nection.java:1174) Can anyone help me with resolving this? Rene Larsen Ranch Hand Posts: 1179 I like... posted 8 years ago An error 503 means: "HTTP 503 is the standard HTTP error that means "Service Unavailable." Is the service running?? Regards, Rene http status Larsen Dropbox Invite Aman Kaur Greenhorn Posts: 9 posted 8 years ago Yes, it is running. the error shows up a couple of times while testing is on!!! any clue? Thanks Rene Larsen Ranch Hand Posts: 1179 I like... posted 8 years ago Maybe the service can't cope with the load you are testing with?? Maybe you need to setup a second server with a Apache http status 503 acting as a loadbalancer in the front, so that you have two severer to handle the requests?? Regards, Rene Larsen Dropbox Invite Aman Kaur Greenhorn Posts: 9 posted 8 years ago Oops....I don't think we would want to do it! Is it possible because of the Apache queue would be smaller than tomcat. Can i tune some parameters and make it working? Aman Kaur Greenhorn Posts: 9 posted 8 years ago After fixing this issue....Now we see the 502 error....!!! any clues?
