Background documentation<sdba_group> (Special Operating System Group) Locate this document in the navigation structure

 

On Unix and Linux, the database system uses the special operating system group <sdba_group>. The system default for the name of <sdba_group> is sdba.

The following database resources have the operating system group ID (GID) of <sdba_group>:

  • Files and directories of the database software (for example, User Profile Container)

  • Database processes

  • vserver process (SAP MaxDB X Server = communication server)

  • Volumes, if there is no support group for the database

  • Backups

Operating system users who perform administration tasks for the database system belong to the <sdba_group> operating system group. These operating system users can perform the following actions, among others:

  • Creating new databases

  • Accessing the directory <independent_data>/wrk and its subdirectories

  • Accessing the XCONS database tool

  • Accessing volumes, if there is no support group for the database

<sdba_group> is also the primary group for the special operating system user <sdb_user>.
