The configured default is Resource Adapter Level.

Allows you to enable or disable the adapter's Dedicated Session Mode. When the Dedicated Session Mode is enabled in a server, the current client’s request can exclusively hold the server port to which it connects.

For example, if this property is enabled, and the client is connected to a server, it only serves the client until the work is completed, and the session is disconnected. If another client tries to connect to the server during this time, it cannot until the session is completed.

Select True or False. True indicates that Dedicated Session Mode is enabled.

The configured default is False.

Specifies how the adapter establishes the TCP/IP connection:

• Client: The adapter connects to an external server (host/port) to establish the connection. The adapter is in active mode.

• Server: The adapter waits/listens on a certain port for an incoming connection request from an external client. Once the request is received, the adapter accepts the request and establishes the connection. The adapter is in passive mode.

Select Client or Server.

Server is the default setting. Unless you specifically require Client mode, leave this value as the default: Server.

A number indicating the amount of time (in milliseconds) the adapter waits before attempting to connect to an external system.

The configured default is 30000 (30 seconds).

Specifies the maximum number of concurrent connections allowed for the specific listener/monitor which is listening or monitoring a specified TCP/IP port. This represents the capability or availability of this server’s services. Each connect-request from a client gains one concurrent connection. This parameter also represents the maximum number of clients who can concurrently connect to this server’s services, and get served by the specific listener/monitor at the same time.

A number indicating the maximum number of concurrent connections available from a listener/monitor for a specific TCP/IP port. 0 indicates that there is no limit.

The configured default is 50.

Specifies the scope of the accepted connection which is used by the adapter. The two options are:

• Resource Adapter Level: The resource adapter will close the connection upon receiving a closure request, so the connection may keep alive during multiple executions of the Collaboration.

• Collaboration Level: The connection is closed once the Collaboration has been executed, so the connection has the same life cycle as the Collaboration.

Select Resource Adapter Level or Collaboration Level.

The configured default value is Resource Adapter Level.

Specifies the close notification value. When the server receives a notification with content that matches this parameter’s value, the server safely closes the connection and cancels any corresponding schedules.

A String indicating the trigger value that notifies the server to close the connection.

The configured default is QUIT.

Idle Timeout

Specifies the length of time (in milliseconds) for inactivity of the requestor (client). The adapter attempts to detect activity on client side (the other side of the connection). If no client activity (no i/o request comes over the connection from the client) for a specified time period, then the connection is closed from the server side to release the resource. The value is in milliseconds.

An integer that indicates the amount of time (in milliseconds) for inactivity of the requestor (client) before the connection is closed from the server side to release the resource. A value of 0 disables IdleTimeout.

The configured default is 60000 (1 minute).

Specifies the scheduler type for this inbound communication. There are two options:

• Timer Service: The scheduler is configured using the At Fixed Rate, Delay and Period properties.

• Work Manager: The task is scheduled through the J2EE Work Manager. Work Manager is supported by J2EE (JCA 1.5 and above). This scheduler is configured using the Delay and Period properties

Select Timer Service or Work Manager.

If your container doesn’t support JCA Work Manager, select Timer Service.

This property configuration, though visible from the Properties Editor, is disabled. The only available schedule type is Repeated, indicating that the task is scheduled for repeated execution at regular intervals defined by the Period property in this section (see Period).

This property is disabled.

Applies to both the Timer Service or the Work Manager. Specifies, in milliseconds, the length of delay time before the task is executed.

An integer indicating the amount of time before the task is executed, in milliseconds (1000 milliseconds is equal to 1 second).

Specifies the regular interval, in milliseconds, between successive repeated task executions. This is used for the Repeated Schedule Type. See Schedule Type. Applies to both the Timer Service or the Work Manager.

An integer indicating the amount of time between successive task executions, in milliseconds.

Enter a positive integer. The configured default is 100. Lowering this value may increase the number of transactions per second.

Specific to the Timer Service configuration only. Specifies whether a Fixed-Rate execution or Fixed-Delay execution is used.

• Fixed-Rate: A fixed-rate execution means that each execution is scheduled relative to the scheduled time of the initial execution. If an execution is delayed for any reason (such as garbage collection or other background activity), two or more executions will occur in rapid succession to catch up. In the long run, the frequency of execution will be exactly the reciprocal of the specified period (assuming the system clock underlying Object.wait(long) is accurate).

• Fixed-Delay: A fixed-delay execution means that each execution is scheduled relative to the actual time of the previous execution. If an execution is delayed for any reason (such as garbage collection or other background activity), subsequent executions will be delayed as well. As a result, the frequency of execution will generally be slightly lower than the reciprocal of the specified period, assuming the system clock underlying Object.wait(long) is accurate.

Select True or False.

True indicates that a fixed-rate execution is used. False indicates that a fixed-delay execution is used.

Specifies the scheduler type for this inbound communication. There are two options:

• Timer Service: This scheduler is configured using the At Fixed Rate, Delay, and Period properties.

Enter a positive integer. The configured default is 100. Lowering this value may increase the number of transactions per second.

Specific to the Timer Service configuration only. Specifies whether a Fixed-Rate execution or Fixed-Delay execution is used. This is used for the “Repeated” schedule type by the “Timer Service” scheduler.

• Fixed-Rate: A fixed-rate execution means that each execution is scheduled relative to the scheduled time of the initial execution. If an execution is delayed for any reason (such as garbage collection or other background activity), two or more executions will occur in rapid succession to catch up. In the long run, the frequency of execution will be exactly the reciprocal of the specified period (assuming the system clock underlying Object.wait(long) is accurate).

• Fixed-Delay: A fixed-delay execution means that each execution is scheduled relative to the actual time of the previous execution. If an execution is delayed for any reason (such as garbage collection or other background activity), subsequent executions will be delayed as well. As a result, the frequency of execution will generally be slightly lower than the reciprocal of the specified period (assuming the system clock underlying Object.wait(long) is accurate).

Select True or False.

True indicates that a fixed-rate execution is used. False indicates that a fixed-delay execution is used.
