Trigger an alert for DST

[former_member223432]

Hi Experts,

Can someone help me a simple way for triggering an ALERT/mail whenever an Daylight saving occur.

we perform some activities whenever DST happens...and we wanted to have a reminder for to as to not to forget the change.

DST occurs 2 times a year..we need 2 notifications or mail triggered automatically...is it possible in PI?

thanks

Why do you want to do that in PI? Why don't you use some calendar functionality? The dates are predefined years in advance. For example, check here:

http://www.timeanddate.com/worldclock/timezone.html?n=179

You could schedule E-Mails to be sent on these dates one week in advance on your E-Mail server. Just be aware that DST for the US and for Europe are not necessarily the same.

Regards,

Jörg

Thanks Indrajit..

Can you please elaborate on the first option...we want this to be simple and autoamted..and we need a reminder only 2 times a year on a particular dates..

if the DST is occuring on Nov 20...we need a reminder a week earlier so that we can plan our changes before hand.

thanks

Hi Smith

You can achieve the same in below way

1. Create a dummy interface that will run on daily at one fix time say 2 pm.Use comm channel availability planing.

2. Create an UDF inside that which will do the below

check whether DST is on or not

Code:

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd' 'HH:mm:ss");

Calendar c = Calendar.getInstance();

int offset = c.get(Calendar.DST_OFFSET);

The offset will be 0 if there is no DST else it will return the time difference in milli seconds.

so if offset is not equal to 0 , then call the function module SALERT_CREATE’ to trigger the alert email.

Sample code for RFC call:

Channel channel = LookupService.getChannel("DE1CLNT100","CC_RFC_R_PI");

RfcAccessor accessor = LookupService.getRfcAccessor(channel);

String rfcXML= "<ns0:SALERT_CREATE xmlns:ns0=\"urn:sap-com:document:sap:rfc:functions\">"+

      "<IP_ALIAS/>"+

      "<IP_APPLICATION_GUID/>"+

      "<IP_CAT>ALERT_TEST_UDF</IP_CAT>"+

      "<IP_XML_CONTAINER/>"+

      "<IT_CONTAINER>"+

         "<item>"+

            "<ELEMENT>ZCUSTOMER</ELEMENT>"+

            "<TAB_INDEX>0</TAB_INDEX>"+

            "<ELEMLENGTH>20</ELEMLENGTH>"+

            "<TYPE>C</TYPE>"+

            "<VALUE>"+pnum+"</VALUE>"+

         "</item>"+

           "<item>"+

            "<ELEMENT>ZMSGID</ELEMENT>"+

            "<TAB_INDEX>1</TAB_INDEX>"+

            "<ELEMLENGTH>70</ELEMLENGTH>"+

            "<TYPE>C</TYPE>"+

            "<VALUE>"+msgid+"</VALUE>"+

         "</item>"+

      "</IT_CONTAINER>"+

    "</ns0:SALERT_CREATE>";

InputStream inputStream =new ByteArrayInputStream(rfcXML.getBytes());

XmlPayload payload = LookupService.getXmlPayload(inputStream);

Payload rfcOutPayload = accessor.call(payload);
