In this blog, we will see the users who get created during the installation of the HANA DB. it's simple but some time we don't know. I hope this small but important information will help you to build your knowledge.
Users Created During Installation
The following users are automatically created during the installation:
1: <sid>adm ( like "hdbadm" )
- The operating system administrator.
- The user <sid>adm is the operating system user required for administrative tasks such as starting and stopping the HANA system.
- The user ID of the <sid>adm user is defined during the system installation. The user ID and group ID of this operating system user must be unique and identical on each host of a multiple-host system.
- The password of the <sid>adm user is set during installation with the password parameter.
2: sapadm
- The SAP host agent administrator.
- If there is no SAP host agent available on the installation host, it is created during the installation along with the user sapadm.
- If the SAP host agent is already available on the installation host, it is not modified by the installer. The sapadm user and password are also not modified.
- The password of the sapadm user is set during installation with the sapadm_password parameter.
3: system
- The database superuser.
- Initially, the SYSTEM user has all system permissions. Additional permissions can be granted and revoked again, however, the initial permissions can never be revoked.
- The password of the SYSTEM user is set during installation with the system_user_password parameter.
