How-To: Comparing DMVPN Single & Dual Tier Architectures - IPSec VPN & mGRE Termination

Greetings to everyone,
I'd like to share a recent article we published that covers the differences between Single and Dual Tier DMVPN deployments. The article aims to help engineers understand the differences at the IPSec VPN level and its termination on the HUB router.
Those interested can following the link below to read up on this hot topic:
Firewall.cx - Comparing DMVPN Single & Dual Tier Architectures - IPSec VPN & mGRE Termination
Topics Covered (Diagram included for every scenario):
- Single Tier Headend, How IPSec Tunnel mode terminate on Hub
- Single Tier Headend, How mGRE Tunnels terminate on Hub
- Dual Tier Headend, How IPSec Tunnel mode terminate on Frontend Router
- Dual Tier Headend, How mGRE Tunnels terminate on Hub
- Links to similar articles that will surely interest
Feedback is always welcome.
Thanks,
Chris.

You might be running a bug, try to check the Cisco Bug Toolkit for a bug (Or Cisco TAC).
Also try to capture the debug as the why the VPN is failing. Since EIGRP packets flow continuously the tunnel should not go down.

Three tier architecture using oracle dev suite 10g & oracle database 9i

hi ,
I am trying to build a software which will manage the database of a hospital through usual form design .
The tools I am using for these are
(1) oracle server database 9i (2) oracle developer suite 10g (3) windows xp professional service pack 2 .
I have designed the form modules in developer suite , created the tables in the database , connected those tables to the form modules using dml statements, now data can be inserted , updates and deleted through the form design . I have also deployed the forms using "run forms through web" and thereby other computers connected to the main computer through lan can also access the software using the web port address and the name of form to be used , these computers are not having oracle developer suite or oracle database installed , but they can access the software through the browser .
In this scenario my question is that , is this a three tier architecture as oracle database is the first tier , oracle developer suite is the middle tier where I am puting all the bussiness logics and oc4j instance is used to connect the database and the dev suite , and for user interaction we have the browser as the third tier ?
or this is a two tier architecture ? if this is a two tier architecture please let me know how can I implement a three tier architecture using oracle developer suite 10g and oracle server database 9i .
Thanks a lot for showing ur interest to read this

You need Oracle Application Server to deploy the forms when you go live.
What you are currently using OC4J which came in the developer suite. It is used only for development purpose and can not have capacity to handle higher load.
3 tier arch
1. Thin Client :-> Browser
2 Middle tier -> Oracle Appln Server /OC4j(in ur case)
3 Database Tier -> Oracle Database

Single Sign on in a 3 tier architecture between SAP Netweaver CE and R/3

Hi All,
I am trying to implement SSO using SAP logon tickets in a 3 tier architecture between NW CE and R/3. But so far I have not been able to crack this.
Let me describe the scenario in detail:
We have two Java EE applications on Netweaver CE7.2 Application Server:
1. UI: Just handles all the UI logic : js, jsp, css, html, extjs .It calls the Business Layer Java EE application to get data from back-end systems.
2. Business Layer: Calls R/3 SOAP services does some processing on them and exposes the data back to the UI via a Restful JSON service (implemented using Java Spring framework)
Both UI and Business Layer Java EE applications define login modules to be used for SAP logon tickets. So the architecture is like this:
UI-RESTfull-->Business LayerSOAP->ABAP R/3
So ideally when the UI link is clicked it prompts the user for authentication (uses CE UME) and then the UI applications calls the Business Layer which then calls R/3. This unfortunately doesn't work. The authentication between UI and Business Layer Application fails.
However if you remove the Business Layer Java EE application and call the SOAP service directly from the UI. SAP logon tickets starts working.
So I have been able to make SAP logon tickets work with the following 2 tier architecture:
UI---SOAP--->R/3
So my Question is:
Is there a way to use SAP logon tickets in a 3 tier architecture between NW CE and R/3 (For the scenario described above)? Any help/pointers/documentation links would be great

Hey Martin,
To enable SSO I updated web.xml and engine-j2ee.xml for both UI and Business Layer application according to the login module stacks defined (the first one) in the following link:
http://help.sap.com/saphelp_NW70EHP1/helpdata/en/04/120b40c6c01961e10000000a155106/content.htm
Initially both UI and Business Layer had the same entries for web.xml and engine.xml. But since this was not working I did all kinds of testing. For UI i used FORM based authentication and for Business Layer I was using "BASIC" authentication.
I tested the following Scenarios:
1. Without any changes to the above XML files: The Business layer rejects any requests from the UI . I checked the Browser and "MYSAPSSO2" cookie was created. Somehow UI doesnt use this to call Business Layer. Or the Business Layer rejects the token itself
2. I removed authentication from the Business Layer application (Web.xml) keeping the UI same: The call went to R3 but returned a "UnAuthorized" error back. In this case also at the browser level "MYSAPSSO2" token was created but was not used by the business layer to call R3.
3. The did all sorts of permutation and combination with the sample login modules provided (See link above) on both UI and Business Layer application . Nothing worked. All combinations led to two results which were the same as 1 and 2
It seems all this is happening because of another application in between UI and R3.
Hope this Clarifies.
Thanks,
Dhannajay

How to install oracle applicatons in a three tier architecture

Hi,
i want to install oracle apps in a three tier architecture?
application tier -- middle tier
database tier -- database tier
Any steps or a meta link document
Regards
Sudharshan

Hi,
http://download.oracle.com/docs/cd/B34956_01/current/acrobat/120oaig.pdf
Pages 2-10 and Pages 2-19 don't specify this ???
They indicate only having to install with rapidwiz 1 time (as root user if appl/ora accounts setup) ??It is mentioned in Page 1-2
Release 12 utilizes the conf_<SID>.txt file in certain situations, for example where the database has not yet been created. The configuration file is also employed in multi-node (distributed) installs, where you only need to enter the install information once, on one machine, and can then copy the configuration file to other machines as required.
If you are installing in an environment where different machines are used to support the database and Applications tiers (as is typically the case), you would run Rapid Install on each machine in turn, starting with the database machine.

How to compare records in singe internal table

Hi Folks,
iam having 3 records in my first itab( T_FINAL) with fields
material no, descrip , mat type and group.
and 16 records in second itab(T_MVKE ) with fields
mat no , distri.chanel and division
now I want to fetch the records from T_MVKE by comparing the records in
T_FINAL .my requirement is to check the given mat no. in sales org.2000,2100. if yes then i have to consider 2000 only, if it is in only 2100 then consider 2100 only . is it is in 2000 only then consider 2100 only
my code is
LOOP AT T_FINAL.
    READ TABLE T_MVKE WITH KEY MATNR = T_FINAL-MATNR.
   IF SY-SUBRC = 0.
   ON CHANGE OF T_MVKE-MATNR OR T_MVKE-VKORG.
IF T_MVKE-VKORG = '2000' and SY-TABIX > 1.
      CONCATENATE '2000' 'TS' P_WERKS T_FINAL-MATNR INTO KEY.
ELSEIF T_MVKE-VKORG = '2000' AND SY-TABIX = 1.
     CONCATENATE '2000' 'TS' P_WERKS T_FINAL-MATNR INTO KEY.
ELSE.
    CONCATENATE '2100' 'TS' P_WERKS T_FINAL-MATNR INTO KEY.
    ENDIF.
this logic fails ,. could tell me how to compare values in single itab?
Thanks
neha

Hi ,
if i've understand you correctly , try that:
LOOP AT t_final.
AT NEW matnr.
    CLEAR: v_2000, v_2100.
*1) 2000
    READ TABLE t_mvke    WITH KEY matnr = t_final-matnr
                                   vkorg = 2000.
    IF sy-subrc = 0.
      v_2000 = 'X'.
    ENDIF.
*2) 2100
    READ TABLE t_mvke    WITH KEY matnr = t_final-matnr
                                   vkorg = 2100.
    IF sy-subrc = 0.
      v_2100 = 'X'.
    ENDIF.
*compare
    IF v_2000 = 'X' AND v_2100 = 'X'.
*read 2000 only
    ELSEIF v_2000 = ' ' AND v_2100 = ' '.
*nothing found
    ELSE.
*all other combinations
*read 2100 only
    ENDIF.
ENDAT.
ENDLOOP.

How to create a single report using 5 difftent reports

Hi Experts
how to create a single report using 5 repors in it.
Example
I have to create a Survey history report using
Reports like Surevy 1
                  Surevy 2
                  Surevy 3
                  Surevy 4
                  Surevy 5
Please suggest me.
Santosh

Use Analysis Process Designer (RSANWB) to feed each of the survey BEX reports to one DSO. Assuming each of the surveys has something in common to compare. Could also be used as a snapshot storage for the surveys in case history needs to be compared/archived.
Build the Direct update DSO with the survey objects. Add needed time characteristics and/or version control objects to the key.
Data sources will be the 5 surveys.
Add formula to hardcode version/time for history.
Data target is the direct update DSO.

How to compare date which is greatest date

iam new to sql
how to compare date which date is greatest date with example
can i use to_char to compare date
SELECT eno, ename, GREATEST (TBLE.MAX1, TBLE.MAX2) recent_date "
               FROM (SELECT TBLA.eno, TBLA.ename, "
               MAX (TO_CHAR (TBL.date1, 'MM/DD/YYYY HH24:MI') "
               ) MAX1, "
               MAX (TO_CHAR (TBL.date2, 'MM/DD/YYYY HH24:MI') "

in above query if any one of the date having null value then recent_date is showing 'null'
and also it showing wrong value
example
date1='08-22-2009' and date2='01-23-2010' then it showing wrong recent_datel ike='08-22-2009'
as according my knowledge it is comparing with month it sholud not be like this wat i have to do pls explain with example my o/p should come for recent_date like =''01-23-2010''
Edited by: user9112274 on Aug 27, 2010 5:31 AM

Hi,
there are numerous ways to compare dates, i give you some examples:
with data_Sample as
(select to_date('01-jan-2001','dd-mon-yyyy') d1, to_date('01-mar-2002','dd-mon-yyyy') d2, to_date('03-feb-2002','dd-mon-yyyy') d3 from dual)
select greatest(d1,d2,d3) from data_Sample
GREATEST(D1,D2,D3)
3/1/2002
with data_Sample as
(select to_date('01-jan-2001','dd-mon-yyyy') d1 from dual union all
select to_date('01-mar-2002','dd-mon-yyyy')   from dual union all
select to_date('03-feb-2002','dd-mon-yyyy') from dual)
select max(d1) from data_Sample
MAX(D1)
3/1/2002
declare
d1 date :=to_date('01-jan-2001','dd-mon-yyyy');
d2 date :=to_date('01-jan-2001','dd-mon-yyyy');
begin
if d1>d2 then
dbms_output.PUT_LINE('d1 greater than d2');
else
dbms_output.PUT_LINE('d1 less or equql than d2');
end if;
end;
output:
d1 less or equal than d2now concerning your question:
>
can i use to_char to compare date
>
If you have date data types : don't convert them.
if you have no choice, use something like:
if to_char(d1,'YYYYMMDD') > to_char(d2,'YYYYMMDD') then
else
end if;Take care when you convert a date into a char format it becomes string comparison (with all it implies) (It's the reason why i've use an explicit mask format).

Three(two)-tier architecture - need help

Hello,
very need your advice about implementing 3-tier architecture with .NET.
My intention was to organize the following architecture: server contains data access layer and business layer, and ODP.NET is installed on the server, client requests business layer on the server through .NET Remoting. Business layer on the server returns typed data sets;objects on the server implement interfaces, which return data sets. So, client dlls need to reference only this data sets declaration (which are vendor independent) and interfaces, and no ODP.NET is needed on the client. The problem is that when I generate data source in Visual Studio 2008, it generates also references on ODP.NET, so I cannot reference this project in client application! While I need "pure" data sets, without ODP.NET references, but, at the same time, I want to use auto-generated adapters and not write code manually!
How can I do it?
Thanks in advance.. and need your reply!

For me, I will use Web Services to achieve this. Somehow, you can use other remoting method to do that as well.

Reportings Services in a 2-Tier Architecture / (Installation Error: Could not find SOFTWARE\Microsoft\Microsoft SQL Server\110 registry key. )

Hello,
we want to install Reporting Services in a 2-Tier Architecture. The Servers are the following:
SERVER1: Windows Server 2012 and SQL Server 2012
SERVER2: SharePoint 2013 (WFE)
Reporting Server is installed on SERVER1 and running. On SERVER2 the registration of the service through Powershell was done but it does not start. An Error when starting the Service on the server occurs with the message:
"Installation Error: Could not find SOFTWARE\Microsoft\Microsoft SQL Server\110 registry key."
I have found the following in msdn stating that a minimal of the same SharePoint Installation must exist on the Reporting Server. The article is for SQL Server 2008 R2 and SharePoint 2010. Is this the case also for SQL Server 2012 and SharePoint 2013 and
the root of the problem? http://msdn.microsoft.com/en-us/library/bb510781%28v=sql.105%29.aspx
If so does this mean that I require for the installation another License?!?!
Thank you in advance!

Hi,
According to your post, my understanding is that you wanted to install Reporting Services in a 2-Tier Architecture.
As the article
say, if you use Two-Computer Deployment, the first computer hosts an instance of a SharePoint product. The Reporting Services Add-in is installed on this computer. The second computer hosts SQL Server Reporting Services and the Database Engine.
The steps to install in a two-tier environment are very similar to a standalone environment hence you can go to refer to the ' Install Reporting Services SharePoint Mode for SharePoint 2013' article at http://msdn.microsoft.com/en-us/library/jj219068(v=sql.110).aspx
To install in a two-tier environment, you can refer to:

Upgrade Multiple Instances with single mid-tier

I posted this last week, but it looks like the forums had a little "issue" recently . . .
I know that I can install HTMLDB in many databases and use a single mid-tier (see
http://htmldb.oracle.com/pls/otn/f?p=18326:54:14495624057419435878::::P54_ID:481 )
With this approach, when the time comes (December, right?) I won't have multiple mid-tiers to upgrade, but I will have multiple DB tiers (where the real work happens). How will the upgrade handle this? Will the OUI be able to do it? Will I need to manually run scripts? Will it be supported?
Thanks,

How to compare two IDocs

Hi all,
How to compare two IDoc's. If the both the IDocs are are of same type, i want to distinguish the data in those two IDocs.
Thank you in Advance
Regards
Harsha

Hi Harsha,
Transaction WE05 will help you out.You should first know some details like the
iDoc type, partner, the date/time and maybe the iDoc #. There can be many iDocs
generated/processed per day and without having some info to start with,
one will never find anything useful. Filter what you can, and then
navigate in the left hand frame/double click on the results lines in the
right hand frame to drill down. Eventually you will see the single iDoc
with all the many 'segments' available. Expand the 'data records'
branch (and sub-branches) to see each 'segment' and find the data fields
& values (these will appear in the lower right hand frame).
Reward points if helpful..

Goutham.
