Initialization Parameters, 107 of 220
MTS_DISPATCHERS
configures dispatcher processes in the multi-threaded server (MTS) architecture. The parsing software supports a name-value syntax to enable the specification of attributes in a position-independent case-insensitive manner. For example:
MTS_DISPATCHERS = "(PROTOCOL=TCP)(DISPATCHERS=3)"
Specify only one of the following attributes: PROTOCOL
, ADDRESS
, or DESCRIPTION
. If you specify either ADDRESS
or DESCRIPTION
, you can specify additional network attributes. Doing so supports multi-homed hosts.
PROTOCOL
(PRO
or PROT
)
The network protocol for which the dispatchers will generate a listening end point.
ADDRESS
(ADD
or ADDR
)
The network address (in Net8 syntax) of the end point which the dispatchers will listen on. (Includes the protocol.)
DESCRIPTION
(DES
or DESC
)
The network description (in Net8 syntax, including the protocol) of the end point on which the dispatchers will listen.
DISPATCHERS
(DIS
or DISP
)
An integer specifying the initial number of dispatchers to start. Default is 1.
SESSIONS
(SES
or SESS
)
Specifies the maximum number of network sessions to allow for each dispatcher. The default is set by Net8 and is platform-specific.
CONNECTIONS
(CON
or CONN
)
An integer specifying the maximum number of network connections to allow for each dispatcher. The default is set by Net8 and is platform-specific.
TICKS
(TIC
or TICK
)
Specifies the size of a network tick in seconds. The default is set by Net8 and is platform-specific.
POOL
(POO
)
Enables the Net8 Connection Pooling feature.
ON
, YES
, TRUE
, and BOTH
indicate that Connection Pooling is enabled for both incoming and outgoing network connections. The default timeout (set by Net8) will be used for both incoming and outgoing network connections.
IN
indicates that Connection Pooling is enabled for incoming network connections. The default timeout (set by Net8) will be used for incoming network connections.
OUT
indicates that Connection Pooling is enabled for outgoing network connections. The default timeout (set by Net8) will be used for outgoing network connections.
NO
, OFF
, and FALSE
indicate that Connection Pooling is disabled for both incoming and outgoing network connections. This is the default.
POOL
can also be assigned a name-value string such as: "(IN=10)", "(OUT=20)", or "(IN=10)(OUT=20)". In such cases:
IN
numeric value is specified, then Connection Pooling is enabled for incoming connections, and the number specified is the timeout in ticks for incoming network connections.
OUT
numeric value is specified, then Connection Pooling is enabled for outgoing network connections, and the number specified is the timeout in ticks for outgoing network connections.
MULTIPLEX
(MUL
or MULT
)
Enables the Net8 Network Session Multiplex feature.
1
, ON
, YES
, TRUE
, and BOTH
indicate that Network Session Multiplex is enabled for both incoming and outgoing network connections.
IN
indicates that Network Session Multiplex is enabled for incoming network connections.
OUT
indicates that Network Session Multiplexing is enabled for outgoing network connections.
0
, NO
, OFF
, and FALSE
indicate that Network Session Multiplexing is disabled for both incoming and outgoing network connections. This is the default.
LISTENER
(LIS
, LIST
)
Specifies the network name of an address or address list of the Net8 listeners with which the dispatchers will register.
The LISTENER
attribute facilitates administration of multi-homed hosts. This attribute specifies the appropriate listeners with which the dispatchers will register. The LISTENER
attribute overrides the LOCAL_LISTENER
parameter. See "LOCAL_LISTENER".
SERVICE
(SER
, SERV
)
Specifies the service name that the dispatchers register with the Net8 listeners.
INDEX
Use this parameter in an ALTER SYSTEM SET DISPATCHERS
statement to indicate which dispatcher you want to modify. (If you specify INDEX
in the initialization parameter file, Oracle ignores it.) In an ALTER SYSTEM
statement, INDEX
specifies the order in which the parameter's values were initialized. The value ranges from 0
(for the first dispatcher process) to one less than the total number of dispatchers you define.
For example, if you specify 3 dispatchers in the initialization parameter file, you would modify the third dispatcher by specifying INDEX
=2
in the ALTER SYSTEM
statement. You could also add an additional dispatcher in the ALTER SYSTEM
statement by specifying INDEX
=3
.
