Instance data store
A DSN for a minimal instance-wide data store is defined by TimesTen
at install time to guarantee that TimesTen always has something with
which to connect.
The following is the definition of the instance DSN for a root
installation:
[TT_
instance]
Driver=
install_dir
/lib/libtten.
suffix
DataStore=/var/TimesTen/
instance
/TT_
instance
The following is the definition of the instance DSN for a non-root
installation:
[TT_
instance
]
Driver=
install_dir
/lib/libtten.
suffix
DataStore=
install_dir
/info/TT_
instance
This data store gets special treatment from the daemon, and has special
access restrictions placed on it. Any user can connect to the instance
data store to change their own password. However, users other than the
instance administrator have only SELECT privileges on the instance
data store.
TimesTen users
TimesTen instance administrator
The owner of a TimesTen installation is the “TimesTen instance
administrator.”
Only a member of the
TimesTen administrators group
can install
TimesTen because only the instance administrator user can administer
TimesTen. The user installing the instance automatically becomes the
administrator for that instance. Only that user may start or stop the
instance, and only that user may administer the other users in that
instance. If the
GroupRestrict
attribute is set, the instance
administrator user must have corresponding group membership.
