  • Oracle Quarterly Critical Patch Updates and OTM

    Hello All,

    I am responsible for the database servers in our OTM environments. To the best of my understanding, here is our OTM architecture:

    OTM 5.5 - Cumulative Update 4
    Database Server: Oracle 10.2.0.3 on RedHat Enterprise Linux 4
    Database Server: Oracle Application Server 10.1.3.3 on RedHat Enterprise Linux 4
    Web Server: Apache/Tomcat on RedHat Enterprise Linux 4

    I have installed Oracle CPU's on other database servers in the past where the only Oracle product was the database server. Our OTM environments include Oracle application components, and I wanted to check here for feedback on patching the application tier. We have the OTM App Server and OAS Forms and Reports installed on our application server. We are using the oracle app server that was bundled with the OTM install. It is my understanding that it is not a full version of OAS. From what I've read, Patching the OAS Forms and Reports install with the Oracle Fusion Middleware 01/09 CPU looks pretty easy, but I wasn't sure if the actual OTM app server installation is within the scope of the Critical Patch process.

    Thanks,

    Joe,

    You may patch the database, but do not patch the OAS (reports) and definitly not the OAS running OTM. It is a hit or miss with reports so unless you plan on debugging reports I would advise against it. Usually any patches for OAS running OTM would be included in a CU patch.

      Nick,

      Would you say it's likely that the same would hold for OTM 5.5 (and 6.0/6.1 - we have all of these in various stages) and WebLogic? That is, patch the DB, but stay away from patching (outside of RU/CU) the WebLogic, JRockit, etc.?

        Scott what you said is correct. Unless the release notes advise to upgrade to a newer version of Weblogic, don't. It will break the startup of OTM. You will have to do this for both 5.5 CU6 and 6.1.

          I thought I'd resurrect this thread, as I've recently had the same question. I opened a SR with Oracle to ask the question, and what I got from them is below my post.

          Based on the note, it would seem that all supporting tiers _should_ be able to be patched, but my gut tells me the same things that I'm reading in this thread, which is "It will break OTM".

          Just thought I'd share what I heard from Oracle.

          From Oracle support..
          ==============

          OTM Policy Regarding CPU (Critical Patch Update) Releases (Doc ID 1063983.1)

          CPUs for non-OTM-installed pieces (e.g. WebLogic or the DB) will be supported
          provided you follow the appropriate product guidelines on when and how to apply
          the CPU. As always, this should be tested in a non-production environment first.
          If the CPU causes OTM to no longer work, you should go to the team that issued
          the CPU, and only come to OTM support once the other team has shown this to be
          an OTM issue.

          If there is a compatibility issue between a CPU and something that OTM does
          install (e.g. JRockit) then the application of the CPU must be coordinated
          with OTM Dev, so that we get you the required piece before you install the CPU.

            Adam,

            Overall, here's how we tackle - both in the G-Log days and now with OTM:
            • Most components (Apache, Tomcat, JRockit, JDK, etc) are patches via OTM patches.
            • OTM is sensitive to changes in WebLogic, due to the way it's integrated. I wouldn't apply any WebLogic CPUs unless specifically tested by Oracle's OTM Support group.
            • We've had very few issues with DB patches and keeping these up with the latest CPUs. This can follow best practices.

              Hi Chris,

              Yeah, that makes sense to me, and follows what I've done in the past. I don't worry about breaking OTM on the database tier, only the app tier. I think what I'll do is push for that tier to be updated via OTM specific patches only.

              Thanks for the reply,

              -Adam
