WebLogic clustering Environment ...

Question

          Hi,
          I have an clustering environment setup ( and see several issues) and was wondering
          if anyone else is having the same kind or are seeing similar issues.
          1) Have a weblogic proxy on win2000 box
          2) have two weblogic instances on another win2000 box.
          3) have two weblogic instances on third win2000 box.
          4) have db and 2 app servers on HPUX box.
          Questions:
          1) Does anyone have this kind of environment running successfully?
          2) Our stuff runs but we see several problems :
          --- sometimes we see blank page which comes back with actual page upon hitting
          refresh
          --- Several images don't show up. It tries to look for images on proxy server
          cache, but does not find it over there. It is in fact in the cache directory on
          one of the weblogic instances.
          --- I log in as one user and then log in as another user, it still brings
          up the page for the previous user.
          Can anyone throw some light on this issues or config.
          Any help / effort is greatly appreciated
          Thanks

Answer 1

If you have a significant site (heavy enough traffic or HLA requirement to
          use >1 proxy) then I suggest putting the static stuff on the proxy or even
          outside of the WL loop altogether. Generally speaking, it is fine to put it
          on the proxy, though, like on Apache.
          Here's the problem, though -- most apps hard-code the relative locations of
          the images. I suggest using a JSP tag for "image path" that uses property
          (config) information to deref the location of the files. That way you can
          dev on a single workstation and deploy to a single server or cluster or
          cluster with a set of proxies out front.
          Peace,
