been selected. If this file is missing, an error occurs after Access Control is enabled.

This file is readable and writable only by the instance administrator. Passwords are stored in encrypted form and are not known to the instance administrator as one way hashes, so they cannot be recovered.

Daemon port

Though the instance registry enforces portTCP/IP uniqueness for TimesTen instances, the possibility of the TimesTen main daemon port conflicting with ports used by non-TimesTen applications always exists. See “Changing the daemon port number on UNIX” on page 39 for ways to change the demon port number after installation.

Authenticating users and privileges

When Access Control is enabled, certain TimesTen utility APIs, XLA operations, utilities, procedures and SQL operations require user authentication. For details on each operation, see the specific chapters of the Oracle TimesTen In-Memory Database API Reference Guide and the Oracle TimesTen In-Memory Database Operations Guide.

All TimesTen utilities prompt for a password if needed. See Chapter 2, “Utilities” in the Oracle TimesTen In-Memory Database API Reference Guide.

Client/Server utilities always prompt for a password if no PWD attribute is specified, since they must always use Authenticate.

Scripts built on utilities requiring passwords may want to use the PWDCrypt attribute, rather than embedding a cleartext password in the script.

Privileges

For a description of the TimesTen Access Control privileges, see “Access Control Privileges” in the Oracle TimesTen In-Memory Database SQL Reference Guide,

GroupRestrict

The instance administrator must be included in the GroupRestrict groups being used.
