Scope of State |
Defines the
scope of the State object, which is an OTD sub-node. The valid options
for this parameter are:
Connection Level: The State has the same life cycle as the connection. Resource Adapter Level: The State has the same life cycle as the resource adapter. The life terminates when the resource adapter is recycled. OTD Level: The State has the same life cycle as the OTD object. This scope represents the life cycle of the State.

Packet Size |
The number
of bytes per packet of data. This number also determines the size of
the buffers. |
A valid numeric value. The default is 1024. |
Timeout |
Specifies the milliseconds of pause
before receiving a response from a server following a sent request. |
A valid numeric
value. The default is 1000. |
Initialize Conversation |
Specifies how the adapter will establish a SNA conversation. Options
are:
|
Select True or False. The default is False. |
Deallocation Type |
Specifies the type of deallocation
required at the end of a conversation when a shutdown is issued. Please
refer to your SNA documentation for more information. |
Select one of the following four
options:
0 - SYNC_LEVEL. 1 - FLUSH 2 - CONFIRM 3 - ABEND
The default is 0 - SYNC_LEVEL. |
Synchronization Level |
Specifies the synchronization level parameter (CM_SYNC_LEVEL). Please refer
to your SNA manual for more information. |
Select one of the following:
The default
is 0 - None. |
Custom Handshake Class Name |
Defines your SNA handshake logic (see Appendix B to
deploy a custom handshake class). |
A fully qualified class name such as com.abc.MyClass. The class
must implement the interface com.stc.connector.snalu62.api.snaCustomerHandshake. No value (leaving the property blank) indicates that
no SNA conversation handshake logic is defined. Instead, a built-in standard handshake logic is
used. |

Connectivity Map Inbound Adapter Connection Establishment
The Inbound Adapter Connection Establishment properties are included in the table.
Table 3 Inbound Adapter—Connection Establishment
|
|
|
|---|
Max Connection Retry |
Specifies the
maximum number of retries to establish a connection upon failure to acquire one. |
A
valid numeric value. The default is 3. |
Retry Connection Interval |
Specifies the milliseconds of pause before
each attempt to reaccess the SNA LU62 destination. This setting is used in
conjunction with the Max Connection Retry setting. For example, In the event that the
adapter cannot connect to the SNA destination, the adapter will try to reconnect
three times in 30 second intervals when the Connection Retries value is 3
and the Connection Retry Interval is 30000. |
A valid numeric value. The default is
30000. |
|
Connectivity Map Inbound Adapter Inbound Connection Management

Table 4 Inbound Adapter—Inbound Connection Management
|
|
|
|---|
Max Connection Pool Size |
Defines the maximum number of concurrent connections for the particular listener/monitor over the
specified SNALU62 destination. 0 (zero) indicates that there is no maximum. |
A valid numeric
value. The default is 50. |
Scope of Connection |
Defines the scope of the accepted connection used by
the adapter. Options are:
Collaboration Level: The connection will be closed once the execution of the Collaboration is completed. The connection has the same life cycle as the Collaboration. Resource Adaptor Level: The resource adapter will close the connection upon closure request. The connection may remain live across multiple executions of the Collaboration.
|
Select Collaboration Level or Resource Adaptor Level. The default is Resource
Adaptor Level. |
|
Connectivity Map Inbound Adapter Inbound Schedules
This section describes the following,
Listener Schedule
Listener Schedule properties specify the schedule that the server must wait for the
new client connection establishment request. This schedule is for the listener/monitor. The following
table lists and describes the Listener Schedule properties.
Table 5 Inbound Schedules—Listener Schedule
|
|
|
|---|
Scheduler |
Specifies the scheduler type for
this inbound communication. Options are:
Timer Service: The task is scheduled according to the Schedule Type, Delay, Period, and At Fixed Rate values. Work Manager: The work is scheduled according to the Schedule Type, Delay, and Period values. If your container does not support JCA Work Management (prior to JCA1.5), select Timer Service.
|
Select Timer Service or Work Manager. The default is
Work Manager. |
Schedule Type |
Defines the type of schedule for inbound communication. Repeated indicates a task
is scheduled for repeated execution at regular intervals defined by the parameter Period. |
The
configured default is Repeated.
Note - This value cannot be changed.
|
Delay |
Specifies the delay in milliseconds
before a task is executed. For further details, refer to the SNA Adapter
Javadoc. |
A valid numeric value. The default is 0. |
Period |
Specifies the regular interval in milliseconds
between successive task executions. This parameter is used in conjunction with the Schedule Type
parameter when set to Repeated. |
A valid numeric value. The default is 100. |
At Fixed Rate |
Used in
conjunction with the Repeated setting for the Schedule Type parameter and the Timer
Service type of Scheduler. Options are:
True: Denotes a fixed rate. Each execution is scheduled relative to the scheduled time of the initial execution. If an execution is delayed for any reason, two or more executions will occur in rapid succession to return to the preset execution schedule. Overall, the frequency of executions will be exactly the reciprocal of the specified period. False: Denotes a fixed delay. Each execution is scheduled relative to the actual execution time of the previous execution. If an execution is delayed for any reason, subsequent executions are delayed as well. Overall, the frequency of executions will generally be lower than the reciprocal of the specified period.
|
Select True or False. The default is False. |
|
Service Schedule

Scheduler |
Specifies
the scheduler type for this inbound communication. Options are:

|
Select Timer Service or Work
Manager. The default is Work Manager. |
Schedule Type |
Defines the type of schedule for inbound communication.
Options are:

Specifies the regular interval in milliseconds
between successive task executions. This parameter is used in conjunction with the Schedule Type
parameter when set to Repeated. |
A valid numeric value. The default is 100. |
At Fixed Rate |
Used in
conjunction with the Repeated setting for the Schedule Type parameter and the Timer
Service type of Scheduler. Options are:
True: Denotes a fixed rate. Each execution is scheduled relative to the scheduled time of the initial execution. If an execution is delayed for any reason, two or more executions will occur in rapid succession to return to the preset execution schedule. Overall, the frequency of executions will be exactly the reciprocal of the specified period. False: Denotes a fixed delay. Each execution is scheduled relative to the actual execution time of the previous execution. If an execution is delayed for any reason, subsequent executions are delayed as well. Overall, the frequency of executions will generally be lower than the reciprocal of the specified period.

completed. Options are:
|
Select True or False. The default is False. |
