Rescheduling the report using BO SDK jsp

I have the below code to reschedule the reports in BO using SDK. But I am not able to do it. The below code just rescheudles the report, but the mail is not sent as per the existing schedule.

Code and scheduled description given below. Any quick pointers are highly appreciated.

<%@ page import = "com.crystaldecisions.sdk.occa.infostore.*" %> 

<%@ page import = "com.crystaldecisions.sdk.framework.CrystalEnterprise" %> 

<%@ page import = "com.crystaldecisions.sdk.exception.SDKException" %> 

<%@ page import = "com.crystaldecisions.sdk.framework.IEnterpriseSession" %> 

<% 

    // logon information 

    String boCmsName  = "***" ; 

    String boUsername = "***" ; 

    String boPassword = "***" ; 

    String boAuthType = "secEnterprise" ; 

          // report 

    String reportName = "SDK_TEST" ; 

          // logon 

    IEnterpriseSession ceSession = CrystalEnterprise.getSessionMgr().logon( boUsername, boPassword, boCmsName, boAuthType ) ; 

    IInfoStore         oInfoStore = (IInfoStore)ceSession.getService( "", "InfoStore" ) ; 

    IInfoObjects oInfoObjects = oInfoStore.query("select top 1 * from ci_infoobjects where SI_NAME='" + reportName + "' " );

    IInfoObject oI = (IInfoObject) oInfoObjects.get(0);

          IInfoObject oSched = (IInfoObject) oInfoObjects.get(0);

           oSched.getSchedulingInfo().setRightNow(true);

           oSched.getSchedulingInfo().setType(CeScheduleType.ONCE);

             oInfoStore.schedule(oInfoObjects);

Now my doubt is can we reschedule the report directly or we need to get all the scheduling info like from/to/events etc and then apply them for the new schedule? I think it will be a tedious job as it could be SMTP or FTP or inbox or anything.
