Create the TimesTen users groupDuring installation, you must specify the TimesTen users group. By default, the TimesTen users group for the instance is the primary operating system group of the user installing TimesTen. If you want the TimesTen users group to be other than the installer primary group, you must specify the name of the group during installation.Alternatively, you can make the TimesTen instance world accessible. However, this is not recommended.The only way to change the TimesTen users group is to uninstall and reinstall the TimesTen instance, providing the new group name during reinstallation.If you do not have an operating system group for TimesTen users, the following outlines certain procedures that must be performed once as user root before installing TimesTen to create the TimesTen users group.Create an operating system group under which the TimesTen instance can be installed. The name timesten is suggested for this operating system group, but you can choose any name that you prefer.Note:Throughout this manual, for our examples, timesten is the name of the TimesTen users group.Add the user who is installing and any users who are using TimesTen to the TimesTen users group that you just created.Provide the name of this group, if different from the default TimesTen users group, during the installation at the appropriate time.The directory and file permissions for the TimesTen installation have the group specified as the group you defined during the installation. This sets the permissions to restrict read and write access for most directories, files, checkpoint files, transaction log files, shared memory segments, and semaphores to this defined group. There are exceptions for certain resources as determined by TimesTen. See "Directory and file permissions" for more information on permissions.Note:On Solaris systems, you must be installed as root to use MemoryLock with a setting of 1 or 2. Databases in a non-root instance of TimesTen can use settings 3 and 4 for this attribute on Solaris systems.
