管理対象環境では、CCI API を使用して JNDI 名前空間から IMSConnectionFactory インスタンスを検索し、そのインスタンスを使用して IMSConnection インスタンスを取得します。
ConnectionFactory cf = null;
if (isManaged) {
//Use JNDI lookup to get ConnectionFactory instance
//Assume the connection factory has a JNDI name of MyIMS
Context ic = new InitialContext();
cf = (ConnectionFactory) ic.lookup("MyIMS");
JNDI が構成されていない場合、CCI アプリケーションが手動で IMSManagedConnectionFactory オブジェクトを構成し、それを使用して接続ファクトリーを取得します。
IMSManagedConnectionFactory mcf = new IMSManagedConnectionFactory();
mcf.setDataStoreName("MyDSName");
mcf.setHostName("myHostNm");
mcf.setPortNumber(new Integer(1234));
...
//Create connection factory from ManagedConnectionFactory
cf = (IMSConnectionFactory) mcf.createConnectionFactory();
次の例では、CCI インターフェースを使用して、
EIS でコマンドを実行しています。public void execute() {
try {
ConnectionFactory cf = null;
if (isManaged) {
//Use JNDI lookup to get ConnectionFactory instance - assumes
//connection factory has JNDI name of MyIMS
Context ic = new InitialContext();
cf = (ConnectionFactory) ic.lookup("MyIMS");
} else {
//Create and set values for ManagedConnectionFactory
IMSManagedConnectionFactory mcf = new IMSManagedConnectionFactory();
mcf.setDataStoreName("MyDSName");
mcf.setHostName("myHostNm");
mcf.setPortNumber(new Integer(1234));
//Create connection factory from ManagedConnectionFactory
cf = (IMSConnectionFactory) mcf.createConnectionFactory();
}
// Create an IMSConnection object
Connection connection = cf.getConnection();
//Create an IMSInteraction from the connection to
//interact with IMS to run the IVTNO transaction (Phonebook)
IMSInteraction interaction = (IMSInteraction) connection.createInteraction();
IMSInteractionSpec ixnSpec = new IMSInteractionSpec();
ixnSpec.setInteractionVerb(IMSInteractionSpec.SYNC_SEND_RECEIVE);
//Create new input record
input = new PhoneBookInputRecordField("cp037");
input.setIn__ll((short)59);
input.setIn__zz((short) 0);
input.setIn__trcd("IVTNO");
input.setTranCodeLength(10);
input.setIn__command("DISPLAY");
input.setIn__name1("LAST3");
input.setIn__name2("");
input.setAllFieldsGiven(false);
PhoneBookOutputRecordField
//Create new output record
output = new PhoneBookOutputRecordField("cp037");
//Execute interaction by calling the execute() method
interaction.execute(ixnSpec, input, output);
//Display output
System.out.println ("Output is: ");
System.out.println("¥nMessage: "
+ output.getOut__mesg()
+ "¥nName:"
+ output.getOut__name1()
+ " "
+ output.getOut__name2()
+ "¥nExtension: "
+ output.getOut__extn()
+ "¥nZipcode: "
+ output.getOut__zip());
} catch (Exception e) {
e.printStackTrace();
} finally {
//Close both the interaction and the connection
interaction.close();
connection.close();
}
}
