It is possible to run the upgrade either in GUI mode or silent mode using the softwareOnlyWithPlugins_upgrade.rsp extracted from the installers. In this case the GUI was chosen. To start the binary installation execute the following
./em13500_linux64.binThis will open the GUI. Select upgrade existing EM and under it select the option upgrade software only and configure later.
Skip the software update download. Previous post showed how (if it works) patches could be downloaded beforehand.
Ensure no pre-req failures.
Give new location for the middleware.
Give repository DB connection details
Ensure following DB pre-req succeeds.
Two DB pre-req will have warnings. One of them is the use of MD5 which was covered in the previous post and is safe to ignore.
The other warning is related to applying of applyg RU 1 (which is minimum version needed when upgrading from 13.4 RU12). Since this will be done after binary install, this warning too could be ignored.
When the next button is clicked following information will be shown.
Upgrade will take care of some plugin by upgrading or migrating them depending on availability.
Select any additional plugin to deploy.
Review Space and install location.
Click the upgrade button to begin the upgrade.
When the upgrade completes run the allroot.sh.
# /opt/xxx/app/software/em/middleware135/allroot.sh Starting to execute allroot.sh ......... Starting to execute /opt/xxx/app/software/em/middleware135/root.sh ...... Check /opt/xxx/app/software/em/middleware135/install/root_vm-em-console_2022-01-11_15-17-28.log for the output of root script Finished execution of /opt/xxx/app/software/em/middleware135/root.sh ......Once the allroot.sh is run click the OK button. This will complete the install of binaries and give instructions on the next step which is to configure the setup but do not run the ConfigureGC.sh until the binaries are patched. It is alright to click the close button before the patch apply.
