The following steps are only for reference. Please refer to the local system for specific steps and operations, and consult the system administrator for specific details.
- Create an installation user group:
groupadd dinstall - Create the installation user:
useradd -g dinstall -m -d /home/dmdba -s /bin/bash dmdba - Initialize user password:
passwd dmdba
