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.
