Step by step - How to install OEM 12c in Linux x86_64

STEP 1- Create a database that will be used as repository database. Here I have created a database OEMDB in RAC. So it has two instances OEMDB1 and OEMDB2. Unlock the sysman user and keep the password of your choice.




STEP 2 - Downlaod the Enterprise Manager Cloud Control 12c Release 1 (12.1.0.5) (x86_64) software from oracle.

STEP 3 - If you have performed a default database installation you will need to deconfigure Enterprise Manager Database Control. Run the following command as the "oracle" user.



STEP 4 - Make the following initialization parameter changes and restart the database.



STEP 5 - Make a directory to hold the Middleware installation and for Agent. Copy the downloaded zipped file to the server and Unzip the Cloud Control media, then start the installation by running the "runInstller" script.



STEP 6 - If you wish to receive support information, enter the required details, or uncheck the security updates checkbox and click the "Next" button. Click the "Yes" button the subsequent warning dialog.



STEP 7 - If you wish to check for updates, enter the required details, or check the "Skip" option and click the "Next" button.






STEP 8 - If you have performed the prerequisites as
described, the installation on linux x86_64 should pass all prerequisite checks. On linux x86_64 there is one failure due "ulimit".This can be ignored by pressing the "Ignore" button, followed by the "Next" button.



STEP 9 - Select the "Create a new Enterprise Manager System" and "Simple" options, enter the middleware home and click the "Next" button.



STEP 10 - Enter the administrator password and database repository details, then click the "Next" button.


STEP 11 -  Ignore the error by clicking "yes" button



STEP 12 - If you are happy with the review information, click the "Install" button.



STEP 13 -  Wait while the installation and configuration take place.



STEP 14 - When prompted, run the root scripts, then click the "OK" button.


STEP 15 - Make note of the URLs, then click the "Close" button to exit the installer. A copy of this information is available in the "/u01/app/oracle/Middleware/oms/install/setupinfo.txt" file.
