TCPIP Server (Inbound) Adapter - General Inbound Settings

The General Inbound Settings properties represents general TCPIP Inbound configuration information. The TCPIPServer (Inbound) Adapter - General Inbound Settings properties contain the top-level parameters displayed in the following table.

Table 1 TCPIPServer (Inbound) Adapter - General Inbound Settings Properties

Name	Description	Required Value
Persistence State File Location	Specifies the directory location (a local folder name) where the state files, used to persist the state value, are stored. This property is required when the Scope Of State is set to Persistence.	The file and path. The default value is `C:/temp/tcpipinbound/state` (depending on the environment settings).

TCPIP Server (Inbound) Adapter - TCPIP Inbound Settings

The TCPIP Inbound Settings properties specify the Java Socket and ServerSocket options. For more information, refer to the JDK Javadoc. The TCPIPServer (Inbound) Adapter - TCPIP Inbound Settings properties contain the top-level parameters displayed in the following table.

Table 2 TCPIP Server (Inbound) Adapter - MDB Properties

Name	Description	Required Value
Host	Specifies the host name or IP address used to establish a TCPIP connection. This parameter is only used when Connection Type is Client.	A TCP/IP host name or IP address.
ServerPort	Specifies the port number of the TCP/IP destination. This is dependent upon the specified Connection Type. If the value for Connection Type is: Server: the ServerPort value is set to the port number on the local host. Client: the ServerPort value is set to the port number of the external host.	An integer between 0 and 65535, indicating the port number of the TCP/IP destination. The port number of the TCP/IP destination. The default is 8888. Note - TCP/IP server connects binds to random port, if the port number is 0.
Backlog	Specifies the maximum length of the queue when creating the ServerSocket. The maximum queue length for incoming connection indications (a request to connect) is set to the backlog parameter. If a connection indication arrives when the queue is full, the connection is refused. Note - This parameter is only used when Connection Type is set to Server.	An integer indicting the queue length for incoming connections. The configured default value is 50.

TCPIP Server (Inbound) Adapter - MDB Pool Settings

Specific to the MDB bean pool of GlassFish Server and Oracle Java CAPS Enterprise Service Bus only. The parameter settings in this section are applied to sun-ejb-jar.xml. The TCPIPServer (Inbound) Adapter - MDB Pool Settings properties contain the top-level parameters displayed in the following table.

Table 3 TCPIPServer (Inbound) Adapter - MDB Pool Settings Properties

Name	Description	Required Value
Steady Pool Size	Specifies the minimum number of MDB beans to be maintained. When the value is set to a value that is greater than 0, the container not only pre-populates the MDB bean pool with the specified number, but also attempts to ensure that there are always this many MDB beans in the free pool. This ensures that there are enough MDB beans in the “ready to serve” state to process user requests. This parameter does not guarantee that more than the “steady-pool-size” MDB instances will not exist at a given time. It only governs the number of instances that are pooled over a long period of time. For example, suppose an idle stateless session container has a fully-populated pool with a steady-pool-size of 10. If 20 concurrent requests arrive for the MDB bean component, the container creates 10 additional instances to satisfy the burst of requests. This prevents the container from blocking any of the incoming requests. However, if the activity dies down to 10 or fewer concurrent requests, the additional 10 instances are discarded.	An integer indicating the minimum number of Message Driven Beans (MDBs) to be maintained. The configured default is 10.
Max Pool Size	Specifies the maximum number of MDB beans in the pool.	An integer indicating the maximum number of MDB beans in the pool. A value of 0 means the pool is unbounded. The configured default is 60.
Pool Idle Timeout In Seconds	Specifies the interval at which the “remove expired MDBs” thread runs. This thread periodically removes unused MDB beans with expired timeouts. This provides a hint to the server, and allows the user to specify the maximum amount of time that an MDB bean instance can remain idle in the pool. After this period of time, the pool can remove this bean. When Pool Idle Timeout In Seconds is set to a value greater than 0, the removes or destroys any MDB bean instance that is idle for this specified duration. A value of 0 specifies that idle MDB beans can remain in the pool indefinitely.	An integer indicting the Pool Idle Timeout in seconds for unused MDBs. A value of 0 specifies that idle MDBs can remain in the pool indefinitely. The configured default value is 600.

TCPIP Client (Outbound) Adapter - General Outbound Settings

The General Outbound Settings properties represents general TCPIP outbound configuration information. The TCPIP Client (Outbound) Adapter - General Outbound Settings properties contain the top-level parameters displayed in the following table.

Table 4 TCPIPClient (Outbound) Adapter - General Outbound Settings Properties

Name	Description	Required Value
Persistence State File Location	Specifies the File Location (a local folder name). This property is required when the Scope Of State value is set to is Persistence. This file is used to store the state files which are used to persist the state value.	The file and path. The default value is /temp/tcpipoutbound/state.

TCPIP Client (Outbound) Adapter - TCPIP Outbound Settings

The TCPIP Outbound Settings properties represents general TCPIP outbound configuration information. The TCPIP Client (Outbound) Adapter - TCPIP Outbound Settings properties contain the top-level parameters displayed in the following table.

Table 5 TCPIPClient (Outbound) Adapter - TCPIP Outbound Settings Properties

Name	Description	Required Value
Host	Specifies the host name or IP address used to establish a TCPIP connection. This parameter is only used when the Connection Type is set to Client.	A TCP/IP host name or IP address. The configured default is localhost.
ServerPort	Specifies the port number of the TCP/IP destination. This is dependent upon the specified Connection Type. If the value for Connection Type is: Server: The ServerPort value is set to the port number on the local host. Client: The ServerPort value is set to the port number of the external host.	The port number of the TCP/IP destination. The default is 7777.
Backlog	Specifies the maximum length of the queue when creating the ServerSocket. The maximum queue length for incoming connection indications (a request to connect) is set to the backlog parameter. If a connection indication arrives when the queue is full, the connection is refused. Note - This parameter is only used when Connection Type is set to Server.	An integer indicting the queue length for incoming connections. The configured default value is 50.

TCPIP Client (Outbound) Adapter - Connection Pool Settings

Specific to the RA connection pool of GlassFish Server or the Oracle Java CAPS Enterprise Service Bus only. The parameter settings in this section are applied to sun-ra.xml.

The TCPIPClient (Outbound) Adapter - Connection Pool Settings properties contain the top-level parameters displayed in the following table.

Table 6 TCPIPClient (Outbound) Adapter - Connection Pool Settings Properties

Name	Description	Required Value
Steady Pool Size	Specifies the minimum number of RA connections to be maintained. When the value is set to a value that is greater than 0, the container not only pre-populates the RA connection pool with the specified number, but also attempts to ensure that there are always this many RA connections in the free pool. This ensures that there are enough RA connections in the “ready to serve” state to process user requests. For example, suppose an idle stateless session container has a fully-populated pool with a steady-pool-size of 10. If 20 concurrent requests arrive for the RA Connection component, the container creates 10 additional instances to satisfy the burst of requests. This prevents the container from blocking any of the incoming requests. However, if the activity dies down to 10 or fewer concurrent requests, the additional 10 instances are discarded.	An integer indicating the minimum number of RA connections to be maintained. The configured default is 1.
Max Pool Size	Specifies the maximum number of RA connections in the pool.	An integer indicating the maximum number of RA connections in the pool. A value of 0 indicates that the pool is unbounded. The configured default is 32.
Pool Idle Timeout In Seconds	Specifies the interval at which the “remove expired RA connections” thread runs. This thread periodically removes unused RA connections with expired timeouts. This provides a hint to the server, and allows you to specify the maximum amount of time that an RA connection instance can remain idle in the pool. After this period of time, the pool can remove this bean. When Pool Idle Timeout In Seconds is set to a value greater than 0, the container removes or destroys any RA connection instance that is idle for this specified duration. A value of 0 specifies that idle RA connections can remain in the pool indefinitely.	An integer indicting the Pool Idle Timeout in seconds for unused RA connections. A value of 0 specifies that idle RA connections can remain in the pool indefinitely. The configured default value is 600.
