Need test documents for RAC failover Scenarios

Hello friends...
By the end of this week i have to produce sum test documents for RAC and Database server including Sun Cluster Failover Scenarios.
Can sumone guide me to a link where i can get enough help.
I have already managed to get enough information.. but i want to see to it that i cover most of the topics.
Thanks, Regards

Toplink support for RAC Failover

We need to enable Toplink to support RAC Fast Connection Failover. We need to support
only read query retry functionality and not write query retry. We found one document
(http://www.oracle.com/technology/events/develop2007/presentations/oracle_jdbc_high_availability_load_balancing_best_practices_and_road_map.pdf)
that explains how to configure JDBC connection for RAC failover. However, since we
are using Toplink, we don't explicitly write our own jdbc url and toplink's session/uow
will automatically handle the actual sql query execution.
Is there any way we can configure Toplink to support RAC Fast Connection Failover, such
as possibly in the toplink's sessions.xml or in the oc4j container's connection pools setting?
Just for information, the way we acquire Toplink session is through SessionFactory:
   SessionFactory sessionFactory = new SessionFactory("repository",
                                 "META-INF/repository-sessions.xml");
   Session toplinkSession = sessionFactory.acquireSession();Then we do queries, acquiring unit of work, etc, using that toplinkSession.
Thanks.

We have enhanced our RAC FCF support in 11gR1 leveraging the new Universal Connection Pool to make it more seamless to the application. Which version of TopLink and OC4J are you using?

Document for JMS Failover Implementation On WebLogic

Hi,
I am looking some good links and techniques to implement JMS failover using WebLogic 10.3.
FailOver* [As we do with our Databases (Concept of Clustring)]
System will consist of two app servers and each will have its own application deployments but if one failed for some reason the application messages should redirected to the other servere and vice versa.
Above efinition is very brief but if anyone can help provide some good documents and info how to implement it it will be appriciated.
Thanks :-)

Thanks alot guys for your help. We successfully implemented it at our servers here by creating distributed queues targetting all servers in a cluster.
One point which I think is worth mentioning and I want to share with all us here is that; when App Server [where MDB will post the message finally after retrieving from queue] if that goes down what will happen, what MDB will do with that message?.
We impleneted the DLQ (error destination) and deploy one more MDB_DLQ_SERVER2 (Let say App SERVER 1 is down) which gets triggered when any message comes to DLQ and post that message to some other App Server, Let say message has been read by MDB_SERVER1 on SERVER1 but offcourse actaull server is down so message should get Re-directed to its Error Destination after it expiration peiod or whatever the settings are. DLQ (Error Destination) which is also a distributed destinatrion again targetting all servers in cluster same as actaull Request or Reply queues BUT MDB_DLQ_SERVER2 which is deployed on Server2 is NOT able to read this message. It get triggered but can not access the message.
After debugging for almost a day we found out its because message has been transafed to DLQ but actaully its resides in a FILESTORE_SERVER1 and MDB_DLQ_SERVER2 is not able to access it.
To work with that we have to define MDB_DLQ_SERVER1 to cater the SERVER1 failure and MDB_DLQ_SERVER2 to cater SERVER2 failure.
Reason I am mentioning this because as I said DLQ is also a normal Distributed Queue but at the same time its NOT as Distributed as its says.
Hope you all understand what I just wrote above.
Now I need to implement exactly the same scenario using four seperate physicall machine containing my four servers. I tried this scenario by creating four machines where node manager for each server is running and listning but when I am trying to start the server it gives me Certificate Exception with bad user name and password. Anyway I have seen some posts here regarding this; So i think i'll be fine.
Thanks Again,
Sheeraz

Need a document for field exit....urgent

Can any one please send a document for field exit or have a simple document on how to work on a field exit with screen shots. pls send it ...its urgent
Thanks and regards

Hi,
A field exit is a type of user exit.
A user exit is a hook where you can inject your own add-on functionality or behavior to SAPs standard business applications without having to modify the original applications.
Field exits allow you to create your own programming logic for any data element in the Dictionary. You can use this logic to carry out checks, conversions, or business-related processing for any screen field.
Field Exits
Field exits allow you to create your own programming logic for any data element in the Dictionary. You can use this logic to carry out checks, conversions, or business-related processing for any screen field. Example: The data element BBBNR identifies a companys international location number. You might want to set up your R/3 System so that all international location numbers are larger than 100.
The field exit concept lets you create a special function module that contains this logic.
You assign the special function module to the data element BBBNR. You then assign the module to any programs and screens in which users can add new international location numbers. When you activate your field exit, the system automatically triggers your special routine whenever a user enters a company location number.
In 4.6c, you can use "RSMODPRF" program to create field exits.
An example of a user exits :-
MODULE user_exit_0001 INPUT
    CASE okcode.
        WHEN 'BACK OR EXIT'.
            CASE sy-dynnr.
                    WHEN '100'.
                         SET SCREEN 0.
                         LEAVE SCREEN.
                    WHEN '200'.
Note that you can write any code that satisfy your needs.                                                     ****
But in this case, this was wrote as a sample code for reference sake.                                    ****
And you can test it.                                                                                ****
                         SET SCREEN 100.
                         LEAVE SCREEN.
             ENDCASE.
      ENDCASE.
Field exits (SMOD/CMOD) Questions and Answers
1. Field exit was created with CMOD, but is not processed when calling the screen.
- Since the field exit is not processed until PAI, an action must be triggered on the screen (Return, Save, ...).
- Set profile parameter abap/fieldexit to YES and restart the system.
- After activating the function module FIELD_EXIT... and the field exit, leave the transaction on whose screen the field exit is to be executed. The screen is not generated until the transaction is started.
- Do not work on different application servers since there may be some delay before the field exit is activated.
- The profile parameter must be set on all or none of the application servers.
- If the field exit is to only be active on specific screens, check whether you chose the correct program and the correct screen
      number (take care with subscreens).
- Using SE51 -> Field list, check that the screen field does have a reference to a data element. In the name of the field exit use the name of the data element and not the field name.
- After transport, field exits are marked as active but will not be processed.
   Tip: First try deactivating the field exit once more and then afterwards, activate it again.
2. How is performance affected by setting abap/fieldexit?
- If a screen is generated and the profile parameter is set, a check is run on 2 tables (TDDIR, TDDIRS) to see whether a field exit must be generated for the respective field. In practice, the screen load is not generated until the screen is selected after an
update. The user should not notice any difference because screen generation is very fast.
3. Can you read the contents of other screen fields in the field exit?
- In principle, every field exit can store its value in the global variables of the function group (TOP) and hence make them
available to other field exits. Note here that field exits are always called and not only if an entry is made in the field or if the field is empty. In addition, it is not possible to make any assumptions about the order in which the field exits will be called in the future.
4. How does the field exit behave on step loop fields ?
- After the user has entered data, the field exit is called in PAI as often as there are visible fields in the step loop. The system
variable SY-STEPL is incremented each time. If a new value is assigned to the field, it is displayed in the module between LOOP and ENDLOOP. This module is also called once for each visible step loop line.
5. Can field exits be debugged ?
- No. Field exits must be tested separately in the ABAP/4 Development Workbench. For errors which only occur in the screen environment, it is helpful to write interesting variable to the file system using TRANSFER... . These can then be analysed there.
6. What can you do if the field contents are no longer transported to to ABAP/4.
- Check whether a value is assigned to the field OUTPUT.
7. When is the field exit called if a conversion exit is attached to the
   data element ?
- The field exit is called after the conversion exit. This means that the INPUT field receives the data in the same format as the
ABAP/4 program also receives it.
8. Although a global field exit is inactive, a function module is called which does not exist (for example FIELD_EXIT_PROGRAMM_@)
- This is an error in the kernel which no longer occurs as of 3.0C. As a temporary measure, it is useful to assign a program and a screen which do not exist to the field exit and then activate the field exit.
9. Field exit is not visible in CMOD, although created.
- If you want to create a field exit for a data element, a function module is proposed with the name FIELD_EXIT_. This
function module must exist for the field exit to work. If you do not create this function module, but do create one with a suffix,
the data element is not displayed in CMOD.
10. Field exit is not executed although it is active.
- Fields which do not have the 'Input field' attribute usually do not trigger a field exit. The field exit is designed to allow an
extended input check. It is therefore only called for input fields - even if they are not ready for input at runtime of the         application by LOOP AT SCREEN.
This rule does not apply, however, if the field is located within a steploop. Here the field will be always activated, even if it is
invisible.
- Field exits can only be executed for fields that are directly related tothe dictionary. If the relation is indirect, i.e. via an       ABAP declaration ( LIKE ), no field exit can be executed.
11. Field exits on check buttons do not work
- Field exits are only intended for input fields. As check buttons count as graphical elements, you cannot install field exits on
them.
12. Field exits do not work on selection screens
SAP Field Exits
From 4.6c onwards, Field exits will no more be supported by SAP. They removed the function of field exit but they had given lot of flexibility through userexit.
However, if you still required it, here is how to activate it :-
First called up transaction CMOD.
Then called up transaction PRFB.
or
Activation of the field exits and assignment of the dynpros can also be carried out using program RSMODPRF. For this purpose, the program must be started without parameters (input fields remain blank). If required, new field exits can be created using program RSMODPRF (see the program documentation).

Need Mapping logic for the following scenario

Hi everyone,
I need a mapping logic for the following scenario.
For the same order no with same material no, the quantity should be summed and only one idoc should be created.
For the same order no with different material no, no need to sum the quantity and only one idoc should be created.
For example:
Source Structure:
Ord No      Mat No      QTY
12               1               2
13               1               3
13               2               1
12               2               4
15               1               5
14                3              7
12               1              6
Target Structure:

Try the graphical mapping as shown below using concat with a space as delimite and UDF to split the value again by space.
1. Idoc node
(RootContext)
OrdNo
     |concat[ ] -> sort[asending] -> SplitByValue -> collapseContexts -> Idoc
MatNo                case sensitive    [ValueChange]
(RootContext)
2. OrdNo
OrdNo(RC)
     |concat[ ] -> sort[asending] ->SplitByValue->collapseContexts->SplitByVale-> UDF to fetch ordno -> OrdNo
MatNo(RC)           case sensitive    [ValueChange]                [eachValue]   (return var1.split(" ")[0];)
3. MatNo
OrdNo(RC)
     |concat[ ] -> sort[asending] -> SplitByValue ->collapseContexts->SplitByVale-> UDF to fetch ordno -> MatNo
MatNo(RC)              case sensitive    [ValueChange]                  [eachValue]   (return var1.split(" ")[1];)
4. Qty
               [asending,case sensitive]
               -- sortByKey -----> formatByExample -> sum ->Qty
OrdNo(RC)           |          |          ^
     |concat[ ] -> |            Qty(RC)          |

Hi,
the cause of this message is a change number (rc271_di_imp-aennr), which has an valid-from date different to the valid-from date of the work plan (aenr-datuv was the 01 September 2010 and plko-datuv the 10 November 2010).
By clearing of the change number into structure rc271_di_imp structure appears this message does not occur.

Need installation document for OEM 11G on windows 2003(32 bit).

Hi,
As a part of my project, i need to install the OEM 11G on windows 2003(32 bit) machines and targets also windows 2003. there i need to install again agent 11g(11.1.0.1) and target DB is 10.2.0.4.
I have done the installation of OMS successfully and installed the agent 11g on target as well. i am facing challeges in configuring the database from OMS. i tried couple of options but nothing is working out. Finally i decided to cross check the installation procedure once again with the previously completed ones. could any body share the same.
in breif i have done following.
1) installed RDBMS 11G on OMS server.
2) insalled java 1.6.18.
3) installed WLS 10.3.2
4) installed the OMS 11G(11.1.0.1)
On agent side i installed agent 11g(11.1.0.1) to monitor a database which is of 10.2.0.4 version.
agent,listeners are reflecting on OMS with up status but DB is showing as "metric collection error". i tried all the possible options like removing and reconfiguring and agent clearing and agent restart etc...but no use. also i in the Oracle installation document, they mentioned as we need to set user equavelence between OMS and agent server but not sure of this, which i have not done. is this compulsary?
Sorry for putting all the things in one single thread.
Thanks in-advance.
Regards
DBA.

Did you check if the database is configured in GC?
If you can't connect using sqlplus to the user dbsnmp make a connection to the database: alter user dbsnmp identified by <password> account unlock;
In GC go to Targets, All Targets select the DB concerned and hit Configure. Enter the dbsnmp user password etc. After a while you will see the result: DB shows Up (I hope)

First, "cheating" will likely invalidate your certification. See the OCP FAQ as a start.
That said, if you go via exam (e.g. 1Z0-042) links on

you will find recommended preparation, authorized practice exams and exam topics.

Cluster Adobe Document Services for Failover scenario

Hello All,
We have ADS installed and working in our Dev/QA environment deployed on its own standalone Web AS Java. Going forward, we want to set up our production systems in a Clustered environment for HA/Failover scenario.
From the notes I have read on marketplace, it is possible to cluster a standalone Web AS java by manually clustering SCS and installing the java CI on one physical node(using local disk) and a java dialog instance on other physical node.
I would like to know once we have clustered the standalone java manually, will there be any difference deploying ADS on this java since only SCS is clustered and CI would be installed on a physical host???
Has someone already implemented this kind of scenario???

Need start up for MI

Hi All,
I'm new to SAP Mobile and need to develop a POC of a running application.
Presently we have few Java Webdynprop application and few .Net based application which we are planning to mobilize. Current infrastructure include WebAS 7.0 environment with NWDI and test server for CE 7.1 EhP1. We don't have ABAP stack among those servers. We have good expertise w/ Java webdynpro and web services.
I went through various documents and SDN and I believe that 'always-connected' type best suits my requirement. Also tried downloading SAP NW Mobile 7.1 SP3 from SDN (40mb) but the installation couldn't be proceeded as I didn't have a PDA handy (was trying on emulators). It didn't let me proceed installation (Full install) until I connect the PDA..it couldn't understand the emulator. Also is this installation for 'occasionally connected' or for both?
Can somebody please let me know what exactly is need to have a working POC (even w/ emulator).
Thanks a lot!
Abhijeet

Hi Abhijeet,
First of all you need tested infrastructure for Mobile 7.1 (including ABAP Atack), refer following documents:
1. Configuration of SAP NetWeaver Mobile 7.1, Release SPS 01
2. Installation Guide for SAP Netweaver Mobile 7.1 as per database (MS SQL Server) and Operating System
3. Master Guide - SAP NetWeaver Mobile 7.1
4. Media List - SAP NetWeaver Mobile 7.1
5. help.sap.com
Extra softwareu2019s used for creation of Mobile Application UI & configuration of Laptop Client

o MAXDB_WINDOWS_I386
o jdk-1_5_0_15-windows-i586-p.exe
o Mobile Client (NWMCLIENTSETUP05P_1-10004844.ZIP)
There is no separate PDA emulator you'll get the PDA emulator once the installation will be done as per configuration guide mentioned above. Refer media list to download zip files from service market place.
Hope above info will be useful to you.

Hi Reneta
For your requirement , Bonus Buy concept should be used. But the best way to meet your requirement is to go with a
new subroutine and assign to the discount condition type in your pricing procedure.But if there are several combination's of materials which can vary the reduction of the price then in the subroutine only you have to write the subroutine with the help of ABAPer that if any vary comes then system should check the prices and vary the prices also. So give your requirement to the ABAPer then he will fulfill your requirement.

UCCE for CCM failover with DNS SRV.

we are testing UCCE for CCM failover with Local DNS SRV. We have enabled the "Use DNS SRV type query:YES"&"Resolve SRV records locally:1" on CVP Call server configuration SIP tab.
The srv.xml file updated with CCM IP addrs in this path \Cisco\CVP\conf\srv.xml
On testing, the agent state moved to reserved state, but call is not delivered. Static Route is added for Phone Extension as "500>,proxy.ipcc.com".
What will be the issue? Kindly let me know what needs to be done.
Thanks & Regards
JP.

So, as Markus already figured out, you need to make sure that your CUCM actually understands that it is the intended recipient for these SIP INVITEs. I.e. if you define the static route to point to cucm.cisco.com you have to specificy the specify the Custer FQDN to be cucm.cisco.com under the 'Cluster Wide Domain Settings' in the CUCM Enterprise Parameters.
A second thing to watch out for the CUCM Group assigned to your SIP Trunks. Each SIP Trunk, like any CUCM device, has a Device Pool, the device pool has a UCM Group defining on which UCM nodes that device 'exists'. For phones that typically means : which UCM nodes can I register to ?
But for SIP trunks this means : which UCM nodes have a SIP deamon process for this Trunk and so which of the UCM nodes will actually accept INVITEs for this trunk. The most common cause for 503 Service Unavailable is probably this, (not all) the CUCM nodes in your DNS / srv.xml round robin are in the UCM Group assigned to the Device Pool configured on the SIP trunk for this Call Server.
Cheers,
Kris
