## <sdba_group> (Special Operating System Group)

### Definition

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

### Use

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

· Files and directories of the database software (such as user profile container)

· Database processes

· vserver process (MaxDB X Server)

· Volumes if there is no support group for the database instance

· Backups

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

· Create new database instances

· Start, stop and update the vserver

· Access the <independent_data>/wrk directory and its subdirectories

· Access the XCONS database tool

· Access volumes if there is no support group for the database instance

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