监听文件 LISTENER.ORA 各参数意思
The following items are available in the network listener configuration file (listener.ora).
* Listener Address Section
* SID_LIST_listener_name Static Service Section
* Control Parameters
The listener.ora file is located in $ORACLE_HOME/network/admin on UNIX and ORACLE_HOME\network\admin on Windows NT, or in the directory specified by the TNS_ADMIN environment variable or registry value.
1. Listener Address Section
The listener address section of the listener.ora file defines the protocol address(es) of the listener.
DESCRIPTION
Purpose: Defines listener protocol address(es)
Example:
listener_name=
(description=
(address=(protocol=ipc)(key=extproc0))
(address=(protocol=tcp)(host=sales-pc)(port=1521)))
ADDRESS
Purpose: Defines a listener protocol address. This parameter can be embedded under a ADDRESS_LIST or DESCRIPTION.
Example:
listener_name=
(description=
(address=(protocol=ipc)(key=extproc0))
(address=(protocol=tcp)(host=sales-pc)(port=1521)))
ADDRESS_LIST
Purpose:
Defines lists of listener protocol addresses. If there is only one list of addresses, it is not necessary to use this parameter. This parameter can be embedded under a DESCRIPTION.
Example:
listener_name=
(description=
(address_list=
(address=(protocol=ipc)(key=extproc0))
(address=(protocol=tcp)(host=sales-pc)(port=1521))))
2. SID_LIST_listener_name Static Service Section
You can use the SID_LIST section of the listener.ora to statically configure service information with the listener.
The SID_LIST is required for backward compatibility with Oracle8 or Oracle7 databases, as well as external procedures and heterogeneous services, and some management tools, including Oracle Enterprise Manager.
Oracle8i database information is dynamically registered with the listener during instance startup. Therefore, this information is not required, unless Oracle Enterprise Manager is used to monitor an Oracle8i database.
sid_list_listener_name=
(sid_list=
(sid_desc=
(global_dbname=global_database_name)
(sid_name=sid)
(oracle_home=oracle_home)
(prespawn_max=99)
(prespawn_list=
(prespawn_desc=
(protocol=tcp)
(pool_size=10)
(timeout=2))
(prespawn_desc=...)))
(sid_desc=...))
SID_LIST contains the following parameters:
GLOBAL_DBNAME
Purpose: Identifies the global database name of the database, a name comprised of the database name and database domain. You can obtain the GLOBAL_DBNAME value from the SERVICE_NAMES parameter in the initialization parameter file. This parameter must be embedded under SID_DESC and should match the value of the SERVICE_NAMES parameter.
Example:
sid_list_listener_name=
(sid_list=
(sid_desc=
(global_dbname=oracle.com)
(sid_name=orcl)
(oracle_home=/usr/oracle)))
ORACLE_HOME
Purpose: Identifies the Oracle home location of the service. This parameter must be embedded under SID_DESC.
Example:
sid_list_listener_name=
(sid_list=
(sid_desc=
(sid_name=extproc)
(oracle_home=/usr/oracle)
(program=extproc)))
PROGRAM
Purpose: Identifies the service's executable program name
Example:
sid_list_listener_name=
(sid_list=
(sid_desc=
(sid_name=extproc)

(sid_desc=
(global_dbname=oracle.com)
(sid_name=orcl)
(oracle_home=/usr/oracle)))
SID_LIST
Purpose: Identifies a list of SID descriptions
Example:
sid_list_listener_name=
(sid_list=
(sid_desc=...)
(sid_desc=...))
SID_DESC
Purpose: Provides service information for a specific database instance. This parameter can be embedded under SID_LIST.
Example:
sid_list_listener_name=
(sid_list=
(sid_desc=...)
(sid_desc=...))
PRESPAWN_MAX
Purpose: Specifies the maximum number of prespawned dedicated server processes the listener creates. This number must be at least as many as the sum of the pool size for each protocol. Set this value to a large number so that prespawned dedicated server processes are always available for new connections. This parameter must be embedded under SID_LIST.
Note: Prespawned dedicated servers cannot be configured on Windows NT.
Example:
sid_list_listener_name=
(sid_list=
(sid_desc=
(global_dbname=oracle.com)
(sid_name=sid)
(oracle_home=/usr/oracle)
(prespawn_max=99)))
PRESPAWN_LIST
Purpose: Specifies a list of prespawnd dedicated server process protocol descriptions. This parameter must be embedded under SID_DESC.
Example:
sid_list_listener_name=
(sid_list=
(sid_desc=
(global_dbname=oracle.com)
(sid_name=sid)
(oracle_home=/usr/oracle)
(prespawn_max=99)
(prespawn_list=
(prespawn_desc=
(protocol=tcp)
(pool_size=10)
(timeout=2))
(prespawn_desc=...)))
PRESPAWN_DESC
Purpose: Defines the protocol on which the listener creates prespawned dedicated server processes, as well as characteristics of the prespawned dedicated server. Each protocol must have its own PRESPAWN_DESC description. This parameter must be embedded under PRESPAWN_LIST.
Example:
sid_list_listener_name=
(sid_list=
(sid_desc=
(global_dbname=oracle.com)
(sid_name=sid)
(oracle_home=/usr/oracle)
(prespawn_max=99)
(prespawn_list=
(prespawn_desc=
(protocol=tcp)
(pool_size=10)
(timeout=2))
(prespawn_desc=...))))

TRACE_FILENO_listener_name
Purpose: Specifies the number of trace files for listener tracing. When this parameter is set along with the TRACE_FILEN_listener_name parameter, trace files are used in a cyclical fashion. The first file is filled first, then the second file, and so on. When the last file has been filled, the first file is re-used, and so on. The trace file names are distinguished from one another by their sequence number. For example, if the default trace file of listener.trc is used, and this parameter is set to 3, the trace files would be named listener1.trc, listener2.trc and listener3.trc. In addition, trace events in the trace files are preceded by the sequence number of the file.
Default: 1
Example: trace_fileno_listener=3
TRACE_LEVEL_listener_name
Purpose: Turns tracing on/off to a certain specified level
Default: OFF
Values:
* OFF - No trace output
* USER - User trace information
* ADMIN - Administration trace information
* SUPPORT - WorldWide Customer Support trace information
