Making an Inquiry (INQY) DL/I call without a PSB object

All Type-2 users of the IMS Universal JDBC driver can use the application interface to call a method that issues the desired Inquiry (INQY) DL/I call and return an appropriate object with the returned data from the call, without requiring the PSB metadata. This functionality is delivered through APAR PH19041/UI74514.

The following code examples illustrate how the application interface enables issuing INQY DL/I calls and return the object with the returned data from the call:

• INQY DBQUERY : A user can issue an INQY DBQUERY call using the application interface. A call can be issued by calling the inqyDBQuery() method from the application interface. A DBQueryInfo object is returned containing the call's returned information.

  
  Application app = ApplicationFactory.createApplication();
  DBQueryInfo info = app.inqyDBQuery();
  info.getReturnCode();
  info.getReasonCode();
  info.getStatusCode();

  Returned data: DBQueryInfo object

  
     public int getReasonCode()
     public String getReasonCodeHex() 
     public int getReturnCode()
     public String getReturnCodeHex()
     public int getStatusCode()
     public String getStatusCodeChars()

• INQY ENVIRON: A user can issue an INQY ENVIRON call using the application interface. A call can be issued by calling the inqyEnviron() method from the application interface. An EnvironInfo object is returned containing the call's returned information.

   
  Application app = ApplicationFactory.createApplication();
  EnvironInfo info = app.inqyEnviron();
  info.getControlRegionType();

  Returned data: EnvironInfo object

  
      public int getReasonCode()
      public String getReasonCodeHex()  
      public int getReturnCode()
      public String getReturnCodeHex()
      public int getStatusCode()
      public String getStatusCodeChars()
      public String getRRSIndicator()
      public String getCatalogIndicator() 

• INQY MSGINFO: A user can issue an INQY MSGINFO call using the application interface. A call can be issued by calling the inqyMessageInfo() method from the application interface. A MessageInfo object is returned containing the call's returned information.

• 
  Application app = ApplicationFactory.createApplication();
  MessageInfo info = app.inqyMessageInfo();
  info.getIMSID();

  Returned data: MessageInfo object:

  
      public int getReasonCode()  
      public String getReasonCodeHex()
      public int getReturnCode()
      public String getReturnCodeHex()  
      public int getStatusCode()
      public String getStatusCodeChars()

• INQY FIND: A user can issue an INQY FIND call using the application interface. A call can be issued by calling the inqyFind() method from the application interface. A PCB name must be entered as a string to issue the call with. A FindInfo object is returned containing the call's returned information.

  
  Application app = ApplicationFactory.createApplication();
  FindInfo info = app.inqyFind(this.expectedPCBName);
  assertEquals(0, info.getReturnCode());
  assertEquals(0, info.getReasonCode());
  assertEquals(16448, info.getPCBStatusCode());

  Returned data: FindInfo object

  
      public short getPCBStatusCode() 
      public String getPCBStatusCodeChar()
      public int getReasonCode()
      public String getReasonCodeHex()
      public int getReturnCode()
      public String getReturnCodeHex()
      public int getStatusCode()
      public String getStatusCodeChars()

• INQY PROGRAM: A user can issue an INQY PROGRAM call using the application interface. A call can be issued by calling the inqyProgram() method from the application interface. A ProgramInfo object is returned containing the call's returned information.

  
  Application app = ApplicationFactory.createApplication();
  ProgramInfo info = app.inqyProgram();
  info.getProgramName();

  Returned data : ProgramInfo object

  
      public String getProgramName()
      public int getReasonCode()
      public String getReasonCodeHex()
      public int getReturnCode()
      public String getReturnCodeHex()
      public int getStatusCode()
      public String getStatusCodeChars()
