Access Control
Introduction
Access Control
With TimesTen you can optionally install a layer of internal security,
which throughout the TimesTen documentation set and in the
installation scripts is referred to as “Access Control.”
The Access Control feature of TimesTen provides an environment of
basic control for applications that use the internally defined privileges.
In TimesTen, user privileges are granted on a instance wide-basis. A
user’s privileges apply to all data stores in a given TimesTen instance or
installation.
Limitations of Access Control and non-root installs
General
You can enable Access Control when you install TimesTen. You can
also choose to enable it after installation by using the ttmodinstall
utility. See “Enabling Access Control after installation on UNIX” on
page 14. Access Control cannot be disabled after installation of
TimesTen. You must uninstall and re-install TimesTen if you want to
disable Access Control.
The instance administrator owns all files in the installation directory
tree. Only the instance administrator can administer the TimesTen
instance. See “TimesTen instance administrator” on page 9. All
TimesTen daemon processes are owned by the instance administrator.
Prior to installing TimesTen as non-root, certain tasks must be
performed by the user root. Those tasks are outlined in “Prerequisites
for non-root installations on UNIX systems” on page 37. You cannot

8Oracle TimesTen In-Memory Database Installation Guide
Cache Connect
For Cache Connect, the TimesTen internal user must match the Oracle
user. External Client/Server users must match the Oracle user. If you are
using the Cache Connect Administrator interface, the user must be an
internal TimesTen user.
Replication
If Access Control is enabled, replication daemon administration and
replication schema changes are restricted to users having the ADMIN
privilege. See “Privileges” on page 13.
Changes are applied to a replicated subscriber data store regardless of
the settings or presence of Access Control on the subscriber.
Instance user configuration commands are not replicated.
Client/Server
If a TimesTen client connects to a Timesten server, and the server side
data store has Access Control enabled, the server’s Authenticate
attribute must be enabled.
To use Access Control with Client/Server applications, when the user is
identified externally, the Client and the Server processes must be on the
same machine. When Access Control is enabled, remote Client/Server
access is only supported with TimesTen internal users.
TimesTen ignores the values of UID, PWD and PWDCrypt if specified
in the Server DSN. These are client-side only attributes. The user name
and password must be explicitly declared on the Client side.
When Access Control is enable, if PWD or PWDCrypt is specified in
Client/Server applications, TimesTen assumes that the user is internally
identified, otherwise TimesTen assumes that the user is externally
identified and authenticated by the operating system.
Instance access
Instance startup/shutdown
Permission to start and stop the main TimesTen daemon is restricted to
the TimesTen instance administrator.
To start the TimesTen main daemon:

Access Control 9
% ttDaemonAdmin -start
To stop an instance:
% ttDaemonAdmin -stop
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.

10 Oracle TimesTen In-Memory Database Installation Guide
Note: All examples in the TimesTen documentation set use the name
timesten to represent the instance administrator.
For details on establishing the TimesTen instance administrators group,
see “Create the TimesTen instance administrators group” on page 37.
On Windows systems, the user System automatically becomes the
TimesTen instance administrator when Access Control is selected at
install time.
On UNIX systems, a TimesTen instance administrator user is the OS
user who installs that instance of Timesten.
TimesTen instance users
TimesTen instance users are user names that have been identified to the
instance. They are defined at the instance level and apply to all data
stores in an instance. Initially, only one user name is known to the
instance: the instance administrator.
Only the instance administrator has permission to create or delete users.
Individual users have permission to change their own passwords.
Instance users may be internal user names or external user names.
Internal user
A user name that has been defined within the TimesTen instance is
referred to as an “internal user.” It has no significance outside of the
particular instance of TimesTen in which it was defined. Internal users
are authenticated by the TimesTen instance. See "CREATE USER"in
the Oracle TimesTen In-Memory Database SQL Reference Guide.
TimesTen user names (as specified in the UID DSN attribute) are
automatically converted to upper case (case insensitive).
External user
A user name that is identified by the operating system or some other
external mechanism is referred to as an “external user.” In this release
only the operating system user name is recognized as an external user.
External users are assumed to have been authenticated by some external
mechanism. See "CREATE USER"in the Oracle TimesTen In-Memory
Database SQL Reference Guide. A password is not required by
TimesTen since the user was authenticated by the operating system at
login time.
UNIX external user names are case sensitive. Windows external user
names are not. When connecting from UNIX platforms, TimesTen

Access Control 11
automatically converts the external user name to upper case, rendering it
case insensitive.
The PWDCrypt attribute allows you to encrypt a password rather to use
cleartext passwords, and it also provides a way to deal with the special
characters and case sensitivity used in passwords that might create
difficulties if specified in clear text within the PWD DSN attribute.
Before installation
Several steps must be taken to prepare a machine for TimesTen
installation. These steps are needed once per machine and require root
permission. See “Installation prerequisites” on page 25. Additional steps
must be performed before installation if either Access Control is to be
enabled or you plan to install as non-root.
TimesTen administrators group
An operating system group needs to be defined for those users who will
be allowed to install and administer TimesTen instances. This can be an
existing group, but we suggest that a group named “timesten” be created
specifically for this purpose. “Create the TimesTen instance
administrators group” on page 37. The member of the TimesTen
administrators group who installs the TimesTen instance becomes the
TimesTen instance administrator for that instance.
Instance registry directory
TimesTen maintains a “registry” of all TimesTen instances installed on a
given machine. The instance registry itself is not required for operation,
but it is essential for correct installation and uninstallation of TimesTen.
It is not accessible by TimesTen users including the instance
administrator user.
On Unix platforms, for root user installs, the instance registry is located
in the directory/etc/TimesTen/. Initial creation of the /etc/
TimesTen/ directory may require root access. Creation of this directory
is a once per machine, pre-installation step. See “Create the TimesTen
registry” on page 38. The disk space required for the files in this
directory is less than 2k bytes.
On Windows the instance registry is contained in the operating system
registry. No action is required by users including the instance
administrator user.

Installation directories, files and the daemon port
Installation of TimesTen must be performed by the chosen instance
administrator user. The instance administrator owns all files in the
installation directory tree. Only the instance administrator can operate
the instance.
Installation directories
The installer suggests default destination directories, based on the user
performing the installation.
Instance home directory
The instance may be installed in any directory to which the instance
administrator has sufficient permission.
On Unix, the installer suggests /opt/TimesTen/tt70 as in previous
releases. For non-root users, the installer suggests the home directory of
the user, usually defined by the environment variable $HOME.
On Windows, the installer suggests the directory pattern as used in
previous releases of TimesTen, C:\TimesTen\tt70.
The TimesTen documentation refers to the installation directory as
install_dir.
Daemon home directory
The “home” or current working directory of the running the main
TimesTen daemon is known as the daemon home directory. This
directory must be owned by the instance administrator, with rwxr-xr-x
permissions on UNIX systems. The daemon verifies both the
permissions and ownership of this directory when it starts up.
On UNIX, the installer suggests the use of install_dir/info if
installed as non-root or /var/TimesTen/tt70 if running as root.
On Windows, the install_dir\srv\info directory is used for this
purpose, just as in previous releases.
Password file
If access control is selected at installation time, user and password data
is stored in the file install_dir/srv/info/ttpasswd.
Initially, this file contains a single entry for the instance administrator.
The presence of this file indicates to the daemon that Access Control has
