Understanding the TimesTen Users Group

On a Linux, UNIX, or macOS host:

• TimesTen restricts access to the installation and the instances created from that installation to members of a single operating system group. This group, called the TimesTen users group, owns the installation and the instances created from the installation. The TimesTen users group must be the primary group for the instance administrator. Create this group (for example, timesten) and add the desired operating system users prior to installation. Once you create the TimesTen users group, you cannot change the name of the group or the group ID.

• Users who wish to access databases through TimesTen utilities or direct mode applications must be members of the TimesTen users group. This group can be the user's primary or secondary group.

• Users who connect to a database through a client connection do not have to be members of the TimesTen users group.

On a Windows host:

• TimesTen is installed by the instance administrator. This instance administrator must be a member of the TimesTen users group.

• Information about the TimesTen installation is contained in the Windows operating system registry.
