Note the following special terms when using this guide:
A client is a system that runs an Oracle-supported application
and connects to the shared database(s) on an Oracle8 Server.
A connect descriptor is a specially formatted description
of the destination for a network connection. Connect descriptors are constructed
using a set of keywords and values mapped to service names. For example,
an Oracle Tool would use a service name representing a connect descriptor
to initiate a TNS connection with an Oracle8 Server. Each connect descriptor
is assigned a service name in the network definition and stored in the
TNSNAMES.ORA network configuration file, in an Oracle Names database, or
in a native naming service.
Domain Name System is a machine used to translate the host
name specified in the TNSNAMES.ORA file into the host internet address
(IP).
External naming refers to service name resolution by using
a supported third-party naming service.
Function or procedure written in a third-generation language
(3GL) that can be called from PL/SQL code. Only C is supported for Oracle8
external procedures.
The global database name specifies the name by which
the network listener registers the database instance with an Oracle Names
Server and the name by which the Oracle Names Server identifies a database.
You can use any alias, but Oracle Corporation recommends setting the global
database name to the value of the INITSID.ORA's DB_NAME and DB_DOMAIN
parameters. The default global database name is ORACLE.WORLD. DB_DOMAIN
can be overwritten by the NAMES.DEFAULT_DOMAIN parameter in SQLNET.ORA
file.
Represents the Oracle home name if you use multiple Oracle
homes. This convention is not applicable for the first Oracle home. The
home name can be up to sixteen alphanumeric characters. The only special
character allowed in the home name is the underscore.
Represents a unique registry subkey for each Oracle home
directory in which you install products. A new HOMEID is created
and incremented each time you install products to a different Oracle home
directory on one machine. Each HOMEID contains its own configuration parameter
settings for installed Oracle products.
Resolves service names through a TCP/IP network's Domain
Name System (DNS) or in the /ETC/HOSTS file. This method is recommended
for simple TCP/IP environments.
Combination of processes and threads that begins each time
a database is started. Identified with a unique SID. A default SID, ORCx,
is installed during installation of the Oracle8 database.
When you install Oracle8 database for the first time on a
machine, your SID is typically ORCL. For each subsequent Oracle8 database
installation into a different Oracle home on the same computer, ORCL is
automatically incremented by one (that is, for a second Oracle8 database
installation, the SID is ORC1, for a third Oracle8 database installation,
the SID is ORC2, etc.).
The background threads and memory areas required to access
an Oracle8 database. A database system requires one instance and one database.
Every Oracle8 instance has a single system global area (SGA); a multiple-user
instance also requires several background threads.
A listener enables an Oracle8 Server to accept connections
from client machines over Net8. Also, referred to as network listener.
Resolves service names to network addresses by using information
configured and stored on each individual client. Local Naming is most appropriate
for simple distributed networks with a small number of services that change
infrequently.
A loopback uses Net8 to go from the server right back to
itself.
Management Information Base. The collection of variables that can be queried to describe attributes of an object, such as the use, performance, and initialization parameters of a database server, for example.
The Oracle client/server communication software that offers
transparent operation to Oracle tools or databases over any type of network
protocol and operating system.
An executable program that enables an Oracle8 server to accept
connections from client machines over Net8.
Known formally as either Oracle8 Enterprise Edition or Oracle8,
the Oracle8 database is an Object Relational Database Management System
(ORDBMS).
Oracle Names stores names and addresses of all database services
on a network on a Names Server. Connection requests are routed through
the Names Server, which resolves the service name to a network address.
The information is then returned to the client
A server that uses Oracle Names to store a service's network
address along with its simple name sot that client applications can request
connection with simple names, rather than lengthy addresses.
The OracleSNMPPeerMasterAgent is the process on a managed
node that accepts queries from the management framework and communicates
with the subagents to answer the query.
The OracleSNMPPeerEncapsulator allows you to encapsulate
the Microsoft master agent so that all SNMP requests from a Network Management
Station (NMS) are sent to OracleSNMPPeerMasterAgent.
A set of products which map Net8 functionality to industry-standard
protocols used in client/server connections.
Default Oracle home directory where Oracle Installer installs
the Oracle8 database on Windows NT.
Default Oracle home directory where Oracle Installer installs
the Oracle8 database on Windows 95/98.
A collection of Names Servers which share a common service
registry.
A server is a host system that runs a multi-user Oracle8
Object Relational Database Management System (ORDBMS) and maintains at
least one database that can be shared by remote clients. Server refers
to the ORDBMS that is using Net8 and is capable of serving any Oracle client.
A service name is a short, convenient name mapped to a network
address contained in a TNS connect descriptor. Users need only know the
appropriate service name to make a TNS connection. Service names are created
with the Oracle Net8 Easy Config or Oracle Net8 Assistant.
A unique name for an Oracle database instance. To switch
between Oracle databases, users must specify the desired SID. The SID is
included in the CONNECT DATA parts of the connect descriptors in a TNSNAMES.ORA
file, and in the definition of the network listener in the LISTENER.ORA
file. Also known as system ID.
SQL is Structured Query Language--the internationally accepted
standard for defining and manipulating relational databases.
SQL*Net is the Oracle7 client/server communication software
that offers transparent operation to Oracle tools or databases over any
type of network protocol and operating system.
A synonym for instance identifier. Often abbreviated to SID.
Transparent Network Substrate (TNS) is the Oracle networking
technology that provides a single application interface to all industry-standard
networking protocols.
A TNS-based application uses the common functions of the
TNS interface to transmit data across one or more networks. Net8 is a TNS-based
application.
Address for Names Server(s) hardcoded into the Names Server
and related clients. Names Server(s) become available at this well-known
address(es), eliminating need for specification of address in configuration
files.
