Issue when calling Stored procedure from application

Question

Dear all,
  Oracle DB version: 11.2.0.3
   OS : RHEL 5.9 64-bit version
  We are trying to execute one of the stored procedure (belonging to oracle DB schema) from our Dotnet application(recites in application server) but it takes more than 30 seconds to fetch the records. The stored procedure is called from application. When we try the same procedure from SQL developer or TOAD it completes within a second. Could anyone suggest on the issue?
Note: we are calling a remote DB view from our DB.
No. of records in the view : 49484929 rows
Thanks in advance,
Imran Khan

Thanks Billy for the reply. The following is the function of the .net application which calls the procedure:
public DataSet ResourceMonitor(String Date, String DateTime, String starttime, String endtime, String Assstarttime, String Assendtime)
try
cLog.StartMethod(this, System.Reflection.MethodInfo.GetCurrentMethod().Name);
Database dbResourceMonitor = null;
DataSet Resourceset = new DataSet();
dbResourceMonitor = DatabaseFactory.CreateDatabase();
DbCommand dbCommand = dbResourceMonitor.GetStoredProcCommand("SP_RESOURCEMONITOR1");
dbResourceMonitor.AddInParameter(dbCommand, "P_Date", DbType.String, Date);
dbResourceMonitor.AddInParameter(dbCommand, "P_DateTime", DbType.String, DateTime);
dbResourceMonitor.AddInParameter(dbCommand, "P_Starttime", DbType.String, starttime);
dbResourceMonitor.AddInParameter(dbCommand, "P_Endtime", DbType.String, endtime);
dbResourceMonitor.AddInParameter(dbCommand, "P_AssStarttime", DbType.String, Assstarttime);
dbResourceMonitor.AddInParameter(dbCommand, "P_AssEndtime", DbType.String, Assendtime);
//dbCommand.Parameters.Add(BuildRefCursorParameter("DEPRECSET"));
dbCommand.Parameters.Add(BuildRefCursorParameter("RECORDSET1"));
dbCommand.Parameters.Add(BuildRefCursorParameter("RECORDSET2"));
dbCommand.Parameters.Add(BuildRefCursorParameter("RECORDSET3"));
dbCommand.Parameters.Add(BuildRefCursorParameter("RECORDSET4"));
return Resourceset;
catch (Exception ex)
cLog.LogMessages(this, ex.Message, cLog.eWiproMessageTypes.ErrorType);
throw ex;
finally
cLog.EndMethod(this, System.Reflection.MethodInfo.GetCurrentMethod().Name);
   The stored procedure SP_RESOURCEMONITOR1 has the following DDL:
CREATE OR REPLACE PROCEDURE SP_RESOURCEMONITOR1
(     P_Date      IN VARCHAR2,     
      P_DateTime      IN VARCHAR2,     
      P_Starttime     IN VARCHAR2,
      P_Endtime     IN VARCHAR2,
      P_AssStarttime     IN VARCHAR2,
      P_AssEndtime     IN VARCHAR2,
       P_Mode     IN NUMBER,
    RECORDSET1 OUT SYS_REFCURSOR,
    RECORDSET2 OUT SYS_REFCURSOR,
    RECORDSET3 OUT SYS_REFCURSOR,
    RECORDSET4 OUT SYS_REFCURSOR
)AS
BEGIN
OPEN RECORDSET1 FOR
Select ROLEMASTER.ROLEID,ROLEMASTER.ROLENAME as ResourceGroup,departmentmaster.DEPARTMENTNAME,departmentmaster.departmentid from Rolemaster
INNER JOIN departmentmaster ON Rolemaster.DEPTID=departmentmaster.DEPARTMENTID
WHERE 1=1 AND sysdate >=Rolemaster.START_DATE AND sysdate<=Rolemaster.END_DATE AND Upper(RoleMaster.Rolename) not like '%HIGHLOADER%' AND displayinlist=1
ORDER BY ROLENAME;
OPEN RECORDSET2 FOR
select ROM.ROLENAME as ResourceGroup, fn_get_resource_status(p_starttime, p_endtime,RM.Resourceid,RM.DeptID) AS Status,upper(RM.Resourceid)as Resourceid,RM.RoleID,RM.DeptID,TRIM(RM.RESOURCENAME) AS RESOURCENAME,'Detail'As Details,'ResChng'As ResChng,'Calender' As Calender FROM ResourceMaster RM
--INNER JOIN DEPARTMENTMASTER DM ON RM.DEPTID = DM.DEPARTMENTID
INNER JOIN ROLEMASTER ROM ON RM.ROLEID = ROM.ROLEID
where --UPPER (DM.DEPARTMENTNAME) IN ('DISPATCH','TRANSPORT','TRANSPORT RAMP')
RM.DEPTID in (select DEPARTMENTID from DEPARTMENTMASTER where displayinadmin=1 and active=1)  ;
if (P_Mode =2) THEN
OPEN RECORDSET3 FOR
select * from mobility_attendance_info_v where TRANSACTIONDATE >= TO_DATE(Substr(p_starttime,1, 9) ,'dd-MON-rr') - 1  order by staffno,TRANSACTIONDATETIME Desc;
END IF;
OPEN RECORDSET4 FOR
select rsa.*,planning.flightno,'' As StTime,SUBSTR(rsa.depdt,11,5) as EndTime from resourceallocation rsa inner join planning ON rsa.planningid = planning.planningid
where TO_TIMESTAMP(rsa.DEPDT,'dd-MON-rr HH24:MI')>=TO_TIMESTAMP(P_DateTime,'dd-MON-rr HH24:MI')  ;
END SP_RESOURCEMONITOR1;
   The view mobility_attendance_info_v  is a called from a remote DB. Hope it's quite clear.
