Configuring Multiple Adapters
2-4 Oracle Application Server Adapter for IMS/TM User’s Guide
2.
Create a
Connection
object using the selected
ConnectionFactory
. A
Connection
is a handle to the underlying network connection to the EIS, which
is identified in the
oc4j-ra.xml
file by the
serverName
property.
3.
Create a
Connection
object using the selected
ConnectionFactory
. Specify
the interaction properties using an
AttuInteractionSpec
object. The
AttuInteractionSpec
object has the following format:
AttuInteractionSpec(java.lang.String name, int verb, int timeOut)
The following table describes the properties that can be specified:
The following is an
InteractionSpec
sample:
AttuInteractionSpec iSpeq = new AttuInteractionSpec("query",
javax.resource.cci.InteractionSpec.SYNC_RECEIVE, 60);
javax.resource.cci.RecordFactory rf = new AttuRecordFactory(con,
mcf.getLogger());
javax.resource.cci.MappedRecord queryRecord = rf.createMappedRecord("query"),
queryRecord.put("##text", "select * from disam:nation");
javax.resource.cci.Record oRec = interaction.execute(iSpec, queryRecord);
4.
Invoke the
execute
method on the interaction to initiate a call to the EIS. Pass
any data for the interaction as input and output records.
5.
Once the interactions have been processed, close the
Interaction
and
Connection
objects.
Configuring Multiple Adapters
Each J2CA 1.5 IMS/TM adapter requires an entry in the
oc4j-ra.xml
file as
described in on page 2-2.
Updating Configuration Information
You can change the configuration settings for a resource adapter by editing the
relevant
connector-factory
entry in the
oc4j-ra.xml
file. For these changes to
take effect, you need to stop and restart Oracle Application Server.
