    Missing xorg-X11-apps , xclock in OL8.2

    3760159

      Hi everyone,

       

      I downloaded Oracle Linux 8.2. I need xclock and somehow it is no where to be found. Check the V996906-01.iso (download from edelivery oracle) and OracleLinux-R8-U2-x86_64-dvd.iso from TechNet oracle, there is nothing in the media with xorg-X11-apps. Anybody have any idea how to get this installed?

       

      Thanks

          It's in the Oracle Linux 8 CodeReady Builder repo which is not on any of the ISOs, only yum.oracle.com:

           

          # dnf config-manager --enable ol8_codeready_builder

          # dnf install xorg-x11-apps

            Thank you so much for your prompt reply !!!! Got it fixed.

             

            If I just need to install xclock only, is that possible ? Before I just yum install xclock.  Our IT is very strict on getting X packages installed.

             

            Thanks again

              No, it's not possible. The xclock binary is now included in the xorg-x11-apps package, so you'd have to install the entire package.

                HI Avi and everybody,

                 

                https://yum.oracle.com/oracle-linux-8.html  said CodeReady Builder is "for development purposes only. Oracle suggests these not be used in production.". I have to get the xclock on the production server and hence be able to use the  DBCA etc.

                 

                Which package repository should be installed?

                 

                Thanks again

                  Production servers do not require xclock or even an X desktop at all. You could do this remotely via VNC or via X11- forwarding over SSH.

                   

                  If you run "yum install oracle-database-preinstall-19c" then all the required packages for an Oracle Database installation will be automatically installed from the supported repositories (ol8_baseos_latest and ol8_appstreams).

                    to use X11 forwarding, still needs to install some X package, isn't it? and perhaps not installing the whole x server, but x client if that is possible in what package if possible?

                     

                    Thanks

                      I have to get the xclock on the production server and hence be able to use the  DBCA etc.

                      You don't need xclock to run DBCA. It's simply just as a lightweight X application to verify your X display is working.

                       

                      What are you trying to accomplish? Running DBCA on your remote server that doesn't have X installed? I suggest you use VNC. I wrote a little utility to simplify the process and use it myself whenever I need to run DBCA ad hoc.

                          Btw, Starting with RHEL 7, twm (Tab Window Manager) is no longer supported, and Also xterm does not fully function anymore and is practically useless. The software is too old and hasn't been updated for a long time. RHEL 8 no longer uses X.org, but Wayland instead.

                            HI Dude,

                             

                            looking at your VNCpilot notes, XORG-X11-utils still need to be installed and that going back to my question earlier.

                            # dnf config-manager --enable ol8_codeready_builder

                            # dnf install xorg-x11-apps

                            https://yum.oracle.com/oracle-linux-8.html  said CodeReady Builder is "for development purposes only. Oracle suggests these not be used in production."

                             

                            Which repository has  xorg-x11-apps?

                             

                            Thanks again

                              You are confusing xlock, xorg-x11-apps and xorg-x-11-utils.

                               

                              xlock is included in xorg-x11-apps, which is no longer supported in EL8, and not needed.

                               

                              xorg-x11-utils is in the ol8_appstream and does not require to enable or install any additional software repositories.

                               

                              Check the following:

                              (You need most of the stuff to install metacity, and enjoy a reasonable user experience, including certain fonts to display DBCA properly. etc.).

                                HI Dude,

                                 

                                Thanks for your reply. I have a different output than yours. xorg-x11-apps   is found in CodeReady Builder but not ol8_appstream.

                                if there are other repositories other than codeready builder, then we can probably install in prod. If possible, Please advise what other repositories does it reside in and is good for production.

                                  Dude!

                                  Thanks for your reply. I have a different output than yours. xorg-x11-apps   is found in CodeReady Builder but not ol8_appstream.

                                  Sorry, but you are confusing x11-apps with x11-utils again. Nowhere did I mention that x11-apps was in ol8_appstream. If you read my previous response, more carefully, I clearly mention that x11-utils is in ol8_appstream

                                   

                                  Forget about xorg-x11-apps, you don't need it.

                                   

                                  [root@localhost setup_oracle]# yum install xorg-x-11-utils

                                  No match for argument: xorg-x-11-utils

                                  Of course this won't work, because it's not xorg-x-11-utils. It's xorg-x11-utils.

                                   

                                  What are you trying to install xorg-x11-utils for? x11-utils does not contain xclock. You don't need xclock. If you have instructions to use xlcock, these instructions are no longer valid for OL8.
