This blog post will demonstrate how to install Grid Infrastructure for a standalone server (Oracle Restart) with and without the Automatic Storage Management (ASM) component. Unfortunately the Oracle Universal Installer does not provide a method to skip the configuration of ASM. To get rid of ASM part, the only way is to perform a software-only installation and run the necessary configuration manually.

Install GI 12cR2 Software Only

Using the installation wizard, the Automatic Storage Management (ASM) component installation cannot be skipped. So I’ll install GI software only as first step.

From 12.2 onwards, GI software requires un-zipping software into a grid home. There won’t be any GI home selection in GUI. So create GI directory and Unzip the software there.

If you do not use an Oracle Pre installation RPM, and you want to use the Cluster Verification Utility, then you must install the cvuqdisk RPM.

Now run GI installation script and follow the steps.
./gridSetup.sh

Select Software Only. Click Next.
