Connection connection = cf.getConnection(); // Create an interaction instance to use to submit the IMS transaction. IMSInteraction interaction = (IMSInteraction) connection.createInteraction(); // Set interactionSpec properties. IMSInteractionSpec iSpec = new IMSInteractionSpec(); iSpec.setInteractionVerb(IMSInteractionSpec.SYNC_SEND_RECEIVE); ... // Create the input record ... // Send the input message to IMS to run the transaction and // return the output message. interaction.execute(iSpec, input, output);
A CCI application can also use an Interaction instance to send a request asnychronously to IMS OTMA to retrieve a queued output message. The message was queued when the output of a Commit Mode 0 interaction on a dedicated persistent socket could not be delivered.
// Get a factory to create dedicated persistent socket connection IMSConnectionFactory cf = null; IMSManagedConnectionFactory mcf = new IMSManagedConnectionFactory(); mcf.setHostName("myHostName"); mcf.setPortNumber(new Integer(9999)); mcf.setDataStoreName("myIMS"); mcf.setCM0Dedicated(new Boolean("TRUE")); cf = (IMSConnectionFactory) mcf.createConnectionFactory(); // Create a connection for use by clientID "CLIENT01" IMSConnectionSpec aCSpec = new IMSConnectionSpec(); aCSpec.setClientID("CLIENT01"); connection = connectionFactory.getConnection(aCSpec); // Create an interaction instance to use to retrieve the asynchronous output message. IMSInteraction interaction = (IMSInteraction) connection.createInteraction(); // Set interactionSpec properties. IMSInteractionSpec iSpec = new IMSInteractionSpec(); iSpec.setInteractionVerb(IMSInteractionSpec.SYNC_RECEIVE_ASYNCOUTPUT); iSpec.setCommitMode(0); ... // Send a request to IMS to return the asynchronous output message. interaction.execute(iSpec, null, output);
A CCI application can also use an Interaction instance to send a message to IMS OTMA to end a conversation:
// Note: conn is a handle to the connection used to carry on the // conversation. An application must use the same connection with IMS Connect // (TCP/IP socket or Local Option connection) for all the iterations // of a conversation. IMSInteraction interaction = (IMSInteraction) conn.createInteraction(); // Set interactionSpec properties. IMSInteractionSpec iSpec = new IMSInteractionSpec(); iSpec.setInteractionVerb(IMSInteractionSpec.SYNC_END_CONVERSATION); ... // Send a message to end the conversation interaction.execute(iSpec, null);

clearWarnings()
Clears all the warnings reported by this
IMSInteraction instance.
|

close()
Releases all resources maintained by IMS Connector
for Java for the IMSInteraction instance.

execute(javax.resource.cci.InteractionSpec interactionSpec,javax.resource.cci.Record input)
Deprecated. The execute(javax.resource.cci.InteractionSpec iSpec,
javax.resource.cci.Record input) method is deprecated.
You should use the execute(javax.resource.cci.InteractionSpec iSpec,
javax.resource.cci.Record input, javax.resource.cci.Record output)
method for all your interactions with IMS. If IMS does not
return an output for an interaction, your execute method
should return a null output record.
Performs an interaction with IMS OTMA via IMS Connect.
This variant of the execute
method is used by applications that
use the Common Client Interface (CCI) to
send a request to IMS OTMA to force the end of
an IMS conversation.
In this case, the interactionVerb property of the
IMSInteractionSpec instance is set to SYNC_END_CONVERSATION,
and the input Record instance is ignored.
|
|
execute(javax.resource.cci.InteractionSpec interactionSpec,javax.resource.cci.Record input,javax.resource.cci.Record output)
Performs an interaction with IMS via IMS Connect.
|
|
getConnection()
Returns the connection associated with this interaction.
|
|
getRecordFactory()
Returns a RecordFactory object that is used to create generic Record
instances.
|
|
getWarnings()
Gets the first ResourceWarning from the chain of warnings
associated with this Interaction instance.

Constructor Detail
IMSInteraction
- public IMSInteraction(IMSConnection aConnection)
aConnection
- The active connection to
IMS Connect that is associated
with this interaction. Method Detail
clearWarnings
- public void clearWarnings()
- throws javax.resource.ResourceException
Note: Currently, IMS TM Resource Adapter does not issue any warnings.
javax.resource.ResourceException
close
- public void close()
- throws javax.resource.ResourceException
javax.resource.ResourceException
- Note: The derived exception javax.resource.spi.IllegalStateException is thrown by close() when the close method is invoked on an invalid (already closed) interaction.
execute
- public javax.resource.cci.Record execute( javax.resource.cci.InteractionSpec interactionSpec,
- javax.resource.cci.Record input)
- throws javax.resource.ResourceException
interactionSpec
- An IMSInteractionSpec instance
containing the properties of
this interaction. input
- The input record for this interaction;
ignored for SYNC_END_CONVERSATION. javax.resource.ResourceException
- - The execute() method was invoked on an
invalid interaction. The interaction
or its associated connection were closed.
Note: The derived exception javax.resource.spi.IllegalStateException is thrown in this case.
- The interactionSpec is null or not of type IMSInteractionSpec. The exception javax.resource.ResourceException is thrown in this case.
execute
- public boolean execute(javax.resource.cci.InteractionSpec interactionSpec,
- javax.resource.cci.Record input,
- javax.resource.cci.Record output)
- throws javax.resource.ResourceException
- An IMSInteractionSpec instance containing:
- the interactionVerb property set to SYNC_SEND_RECEIVE (1)
- the imsRequestType property set to IMS_REQUEST_TYPE_IMS_TRANSACTION (1)
- the commitMode property set to send-then-commit (1)
or
- (for shareable persistent socket connections only) the commitMode property set to commit-then-send (0)
- a Record instance containing the input data of the IMS transaction
- a Record instance for receipt of the output data of the IMS transaction
Both non-conversational and conversational IMS transactions can be run using this variant of the execute method.
This variant of the execute method can also be used on dedicated persistent socket connections to run an IMS transaction using Commit Mode 0, retrieve queued output messages from Commit Mode 0 interactions, or retrieve messages that were inserted to alternate Program Contorl Blocks (PCBs).
For example, to retrieve undelivered output from a Commit Mode 0 interaction on a socket connection dedicated to "CLIENT01", the execute method is invoked with:
- An IMSInteractionSpec instance containing:
- the interactionVerb property set to SYNC_RECEIVE_ASYNCOUTPUT (4)
- the commitMode property set to commit-then-send (0)
- a null for the input Record instance
- a Record instance for receipt of the output message
Note: For interactions on a dedicated persistent socket connection the Interaction instance is obtained from a connection that is dedicated to a particular clientID. The value for this clientID is provided in the IMSConnectionSpec object passed to the getConnection() method used to obtain the connection.
For Commit Mode 0 interactions that use interactionVerb = SYNC_SEND_RECEIVE on a dedicated persistent socket connection, clientID identifies the queue to which the output message will be queued if it cannot be delivered to the client. For Commit Mode 0 interactions that use interactionVerb = SYNC_RECEIVE_ASYNCOUTPUT, clientID identifies the queue from which the message will be retrieved.
interactionSpec
- An IMSInteractionSpec instance
containing the properties of
this interaction. input
- For SYNC_SEND_RECEIVE and SYNC_SEND, a Record
instance that contains the input
for the IMS transaction; null for

- For SYNC_SEND_RECEIVE,
SYNC_RECEIVE_ASYNCOUTPUT,
SYNC_RECEIVE_ASYNCOUTPUT_SINGLE_NOWAIT and
SYNC_RECEIVE_ASYNCOUTPUT_SINGLE_WAIT, a Record
instance that receives the output
data; null for SYNC_SEND. javax.resource.ResourceException
- - The execute() method was invoked on an
invalid interaction. The interaction
