    Java Version for In Place Informatica upgrade

    Thiru Murugan U Active Member

      Dear Team,

       

      We are planning for Informatica upgrade from Informatica PowerCenter 9.6.1.

      If we are going in the path   Informatica 9.6.1 > install HF4 -> Informatica 10.2 -> Informatica 10.4 how we can switch JAVA during in place upgrade or how we can select JDK if we have this upgrade path.

       

      Thanks & Regards,

          In almost all cases the JDK used by the PowerCenter software is installed as part of the software installation, they are bundled. So just make sure that your Java-related environment variables (if there are any) point to the JDK / JRE of the PowerCenter installation, then you're good to go.

          There are also several hints about the process in the Installation and Configuration Guide. You should follow the steps listed in this PDF file carefully.

          Basically you have to make sure that PowerCenter is always used with its own JDK / JRE, then you will be good to go.

           

          The only exception is if you install on AIX; in this case you have to provide the correct JDK / JRE provided by IBM. These steps too are documented in detail in the Installation and Configuration Guide.

            Hi Nico,

             

            Thanks for the update.

            If we perform in place upgrade also we have to follow the same or JDK gets upgraded automatically ?

              The JDK / JRE will be upgraded automatically. Simply because the Informatica platform (i.e. the Tomcat / Apache installation which provides the base software for the Informatica domain) uses its own bundled JDK / JRE.

               

              Sole exception (as noted earlier): on AIX you have to use one particular JDK / JRE per version, download links and installation instructions can be found in the Installation and Configuration Guide.

               

              Regards,

              Nico

                Hi Nico,

                 

                Even if we use upgrade assistance it will take care or we have to update anything .

                 

                Thanks & Regards,

                  As written earlier: with the exception of AIX (where I honestly don't know how that has to be handled) you don't have to care for the new JDK/JRE; that's handled by the installer itself.

                  There's one thing you have to do:

                  If the environment variables of the user ID running the Informatica platform contain any references to the "old" JDK / JRE, then you have to change those environment variables such that no more references to the JDK/JRE can be found in the environment; only after this step you can start the upgrade installer.

                   

                  Regards,

                  Nico

                    Hi Thiru,

                     

                    Java is shipped along with the installers of Informatica, so you don't need to worry about the java versions

                     

                    And we won't ship java for AIX, you need to install it manually and set the JAVA_HOME to that location.

                     

                    Thanks,
