Two interesting posts by Steven Chan

I finally managed to read up on all the blogs and stumbled upon two very interesting articles by Steven Chan that are very relevant to us:

  • OracleAS 10g Upgrade Paths which describes how Oracle eBusiness Suite handles the upgrade and co-existence of the later AppServer versions. As Steven describes there are a lot of Application Server releases and he is trying to shed some light on them.
  • Will the Real JRE Please Stand Up?. This posting describes why you need a specially patches version of Sun 1.5.0_10. Very interesting read and very relevant to us as a technology customer who uses the same tech stack as eBusiness Suite.

  1. Very interesting article about the JRE.
    If anyone has a copy of 1.5.0_10 with the window focus fix, please post a reply and let me know where I can get it.
    After reading the article, I am trying to find a copy to attempt to solve some issues we are having with Oracle Forms and Reports 10G AS.
    We are serving up our application in SSL and requiring client-side certificates, but many users are having issues with the JRE. During longer sessions, the JRE will re-prompt the user for his cert due to security timeouts. However, occasionally the client auth window is blank and locks up the user’s Internet Explorer. IE has to be killed thru task manager, kicking the user out of our application. I am very interested in doing some testing to see if this window focus fix has any effect on that behavior.
    Thanks!

  2. Hi Scott,

    Patch number 5512094 is available on Metalink.

    You’ll need a password though, which I don’t think I should be handing out on Wilfred’s site. Ask Oracle on Metalink and I’m sure they’ll provide one for you.

    It certainly fixed our focus issues. We’re just testing 1.5.0_10 to see if it fixes a lot of browser hanging/crashing we’re experiencing with JInitiator and multiple sessions.

    Cheers,

    Dave

  3. I have tested the newly released JRE 1.5.0_12 and can confirm, that this problem is finally fixed. :-) So I’m now pushing this release out to our customers instead of 1.5.0_10-erdist, which was originally planned.

  4. Jacob, is this the SUN general release or another Oracle special release?

    Do you know what date it was released?

    Cheers,

    Dave

  5. Jacob,

    That’s great news. Also addressing Dave’s question, I assume you mean the normal distro by Sun. It’s great to finally have an official version of Sun that seams to work with Oracle Forms.

    Now, if Sun only had a good mechanism of specifying which versions of the JRE are allowed by your applet. Currently, the dynamic versioning specification is way too limited. As I blogged, earlier you can only specify a minimum version, but no maximum. So, you can specify 1.5.0_12 in this case but it would also use 1.6.x if installed on your machine :-(. You have a workaround with family clsid’s (for which I have a blog posting in the making), but this only allows you to specify the JRE must be from a certain family (1.4.2, 1.5.0, etc), but you loose the possibility to specify a minimum version within that family.

  6. In addition to this, I can see on Steven Chan’s blog, that they certified Apps with the official 1.5.0_12. Interesting read, makes me even more confident to use it for our own application now. There’s really no need for the 1.5.0_10-erdist release anymore, go for the official version. Check it out:
