Step by step – Oracle 12c R2 Database Ubuntu 21.04 Installation

Making Groups & Users

4. 4. Making Groups & User

   Then Add Oracle DB Groups and User
   So make the Groups as:

   sudo groupadd -g 502 oinstall

   Authenticate with the User Admin Pass.
   If Got “User is Not in Sudoers file” then see: How to Enable sudo

   sudo groupadd -g 503 dba

   sudo groupadd -g 504 oper

   sudo groupadd nobody

   sudo groupadd -g 505 asmadmin

   And finally, the User:

   sudo useradd -u 502 -g oinstall -G dba,asmadmin,oper -s /bin/bash -m oracle

   Set a Password with:

   sudo passwd oracle

   
   Take Note of the oracle User Pass :)
