identity management realm
A subtree in Oracle Internet Directory, including not only an
also additional subtrees for users and groups, each of which are protected with
access control lists.
initial ticket
In Kerberos authentication, an initial ticket or ticket granting ticket (TGT) identifies
the user as having the right to ask for additional service tickets. No tickets can be
obtained without an initial ticket. An initial ticket is retrieved by running the
okinit
 program and providing a password.
instance
Every running Oracle database is associated with an Oracle instance. When a
database is started on a database server (regardless of the type of computer), Oracle
allocates a memory area called the
 and starts an Oracle
process. This combination of the SGA and an Oracle process is called an instance.
The memory and the process of an instance manage the associated database's data
efficiently and serve the one or more users of the database.
integrity
The guarantee that the contents of the message received were not altered from the
contents of the original message sent.
java code obfuscation
Java code
is used to protect Java programs from reverse engineering. A
special program (an obfuscator) is used to scramble Java symbols found in the code.
The process leaves the original program structure intact, letting the program run
correctly while changing the names of the classes, methods, and variables in order
to hide the intended behavior. Although it is possible to decompile and read
non-obfuscated Java code, the obfuscated Java code is sufficiently difficult to
decompile to satisfy U.S. government export controls.
Java Database Connectivity (JDBC)
An industry-standard Java interface for connecting to a relational database from a
Java program, defined by Sun Microsystems.
