Oracle Audio Technologies B31679-01 manual Before installation, TimesTen administrators group

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.
