Best Practice for Release prerequisites in POs

Hello...
Do you know a link, or document which explain the way of work of the release prerequisites in POs ??
I know the rest of the setting regarding of the release procedure, the only concern I have is how works the prerequisites
Hope you have a manual, link, document which explain that, like in the school if there are screens or diagrams will be better.
Thanks.

Still searching for information..
I just could find small in SAP Help regarding that... but I wish to find more information with graphics or charts how hows or how to read the prerequisite releases.

Best practice for releases/iterations

I'm working with scenario 2+. I read all the tutorials and articles about JDI and branches (https://www.sdn.sap.com/irj/sdn/weblogs?
blog=/pub/wlg/2408) but I couldnt find the answer about how to approach small versions and releases. Working with JDI, what is the best practice for small versions and for releases? Should I create a new track/branch for each release (1.0, 2.0) ? What should I do for iterations/small versions (1.1, 1.2, 2.1)? Could you tag a group of DCs so then you could return to that tagged version?
Thanks a lot for your reply!

Hi Deborah,
how you deal with SCs, SC versions and tracks depends on your use case.
If you are doing in-house-development there is often no need to maintain other than the last release. So you can work with one SC version and one track. But you can also work with several SC versions and tracks. This enables you to come back to a former release (or version) if you made some critical errors.
If you write software for different customers you always have to create a new SC version (1.0, 1.1, 1.2, 2.0, ...) and then a new track if you implement new features. Your old releases have to be maintained. So you have to have a track as a basis for maintance.
If you say 'My customers always get the latest release even if they did not pay for the new features' you can of course work with a lower amount of SC versions and tracks.
The answer to your question 'Could you tag a group of DCs...' is: NO.
You have to create a new SC version and a new track.
There may also be other approaches but I hope this helps a bit.

Best practice for distributing/releasing J2EE applications.

Hi All,
We are developing a J2EE application and would like some information on the best
practices to be followed for distributing/releasing J2EE applications, in general.
In particular, the dilemma we have is centered around the generation of stub, skeleton
and additional classes for the application.
Most App. Servers can generate the required classes while deploying the EJBs in the
application i.e. at install time. While some ( BEA Weblogic and IBM Websphere are
two that we are aware of ) allow these classes to be generated before the installation
time and the .ear file containing the additional classes is the one that is uploaded.
For instance, say we have assembled the application "myapp.ear" . There are two ways
in which the classes can be generated. The first is using 'ejbc' ( assume we are
using BEA Weblogic ), which generates the stub, skeleton and additional classes for
the application and returns the file, say, "Deployable_myapp.ear" containing all
the necessary classes and files. This file is the one that is then installed. The
other option is to install the file "myapp.ear" and let the Weblogic App. server
itself, generate the required classes at the installation time.
If the first way, of 'pre-generating' the stubs is followed, does it require us to
separately generate the stubs for each versions of the App. Server that we support
? i.e. if we generate a deployable file having the required classes using the 'ejbc'
of Weblogic Ver5.1, can the same file be installed on Weblogic Ver6.1 or do we
have to generate a separate file?
If the second method, of 'install-time-generation' of stubs is used, what is the
nature/magnitude of the risk that we are taking in terms of the failure of the installation
Any links to useful resources as well as comments/suggestions will be appreciated.
TIA

Its much easier to distribute schema/data from an older version to a newer one than the other way around. Nearly all SQL Server deployment features supports database version upgrade, and these include the "Copy Database" wizard, BACKUP/RESTORE,
detach/attach, script generation, Microsoft Sync framework, and a few others.
EVEN if you just want to distribute schemas, you may want to distribute the entire database, and then truncate the tables to purge data.
Backing up and restoring your database is by far the most RELIABLE method of distributing it, but it may not be pratical in some cases because you'll need to generate a new backup every time a schema change occurs, but not if you already have an automated
backup/maintenance routine in your environment.
As an alternative, you can Copy Database functionality in SSMS, although it may present itself unstable in some situations, specially if you are distributing across multiple subnets and/or domains. It will also require you to purge data if/when applicable.
Another option is to detach your database, copy its files, and then attach them in both the source and destination instances. It will generate downtime for your detached databases, so there are better methods for distribution available.
And then there is the previously mentioned method of generating scripts for schema, and then using an INSERT statement or the import data wizard available in SSMS (which is very practical and implements a SSIS package internally that can be saved for repeated
executions). Works fine, not as practical as the other options, but is the best way for distributing databases when their version is being downgraded.
With all this said, there is no "best practice" for this. There are multiple features, each offering their own advantages and downfalls which allow them to align to different business requirements.

Best Practices For Household IOS's/Apple IDs

Greetings:
I've been searching support for best practices for sharing primarily apps, music and video among multple iOS's/Apple IDs. If there is a specific article please point me to it.
Here is my situation:
We currently have 3 iPads (2-kids, 1-dad) in the household and one iTunes account on a win computer. I previously had all iPads on single Apple ID/credit card and controlled the kids' downloads thru the Apple ID password that I kept secret. As the kids have grown older, I found myself constantly entering my password as the kids increased there interest in music/apps/video. I like this approach because all content was shared...I dislike because I was constantly asked to input password for all downloads.
So, I recently set up an individual account for them with the allowance feature at iTunes that allows them to download content on their own (I set restrictions on their iPads). Now I have 3 Apple IDs under one household.
My questions:
With the 3 Apple IDs, what is the best way to share apps,music, videos among myself and the kids? Is it multiple accounts on the computer and some sort of sharing?
Thanks in advance...

Hi Bonesaw1962,
We've had our staff and students run iOS updates OTA via Settings -> Software Update. In the past, we put a DNS block on Apple's update servers to prevent users from updating iOS (like last fall when iOS 7 was first released). By blocking mesu.apple com, the iPads weren't able to check for or install any iOS software updates. We waited until iOS 7.0.3 was released before we removed the block to mesu.apple.com at which point we told users if they wanted to update to iOS 7 they could do so OTA. We used our MDM to run reports periodically to see how many people updated to iOS 7 and how many stayed on iOS 6. As time went on, just about everyone updated on their own.
If you go this route (depending on the number of devices you have), you may want to take a look at Caching Server 2 to help with the network load https://www.apple.com/osx/server/features/#caching-server . From Apple's website, "When a user on your network downloads new software from Apple, a copy is automatically stored on your server. So the next time other users on your network update or download that same software, they actually access it from inside the network."
I wish there was a way for MDMs to manage iOS updates, but unfortunately Apple hasn't made this feature available to MDM providers. I've given this feedback to our Apple SE, but haven't heard if it is being considered or not. Keeping fingers crossed.
Hope this helps. Let us know what you decide on and keep us posted on the progress. Good luck!!

What are the best practices for using the enhancement framework?

Hello enhancement framework experts,
Recently, my company upgraded to SAP NW 7.1 EhP6. This presents us with the capability to use the enhancement framework.
A couple of senior programmers were asked to deliver a guideline for use of the framework. They published the following statement:
"SAP does not guarantee the validity of the enhancement points in future releases/versions. As a result, any implemented enhancement points may require significant work during upgrades. So, enhancement points should essentially be used as an alternative to core modifications, which is a rare scenario.".
I am looking for confirmation or contradiction to the statement "SAP does not guarantee the validity of enhancement points in future releases/versions..." . Is this a true statement for both implicit and explicit enhancement points?
Is the impact of activated explicit and implicit enhancements much greater to an SAP upgrade than BAdi's and user exits?
Is there any SAP published guidelines/best practices for use of the enhancement framework?
Thank you,
Kimberly

Workflow not completed, is this best practice for PR?

Hi SAP Workflow experts,
I am new in workflow and now responsible to support existing PR release workflow.
The workflow is quite simple and straightforward but the issue here is the workflow seems like will never be completed.
If the user released the PR, the next activity is Requisition released that using task TS20000162.
This will send work item to user (pr creator) sap inbox which when they double click it will complete the workflow.
The thing here is, in our organization, user does not access SAP inbox hence there are thousands of work item that has not been completed. (our procurement system started since 2009).
Our PR creator will receive notification of the PR approval to theirs outlook mail handled by a program that is scheduled every 5 minutes.
Since the documentation is not clear enough, i can't digest why the implementer used this approach.
May I know whether this is the best practice for PR workflow or not?
Now my idea is to modify the send email program to complete the workitem after the email being sent to user outlook mail.
Not sure whether it is common or not though in workflow world.
Any help is deeply appreciated.
Thank you.

Hello,
"This will send work item to user (pr creator) sap inbox which when they double click it will complete the workflow."
It sounds liek they are sending a workitem where an email would be enough. By completing the workitem they are simply acknowledging that they have received notification of the completion of the PR.
"Our PR creator will receive notification of the PR approval to theirs outlook mail handled by a program that is scheduled every 5 minutes."
I hope (and assume) that they only receive the email once.
I would change the workflow to send an email (SendMail step) to the initiator instead of the workitem. That is normally what happens. Either that or there is no email at all - some businesses only send an email if something goes wrong. Of course, the business has to agree to this change.
Having that final workitem adds nothing to the process. Replace it with an email.

Best Practice for SRST deployment at a remote site

What is the best practice for a SRST deployment at a remote site? Should a separate router such as a 3800 series be deployed for telephony in addition to another router to be deployed for Data? Is there a need for 2 different devices?

Hi Brian,
This is typically done all on one ISR Router at the remote site :)There are two flavors of SRST. Here is the feature comparison;
SRST Fallback
This feature enables routers to provide call-handling support for Cisco Unified IP phones if they lose connection to remote primary, secondary, or tertiary Cisco Unified Communications Manager installations or if the WAN connection is down. When Cisco Unified SRST functionality is provided by Cisco Unified CME, provisioning of phones is automatic and most Cisco Unified CME features are available to the phones during periods of fallback, including hunt-groups, call park and access to Cisco Unity voice messaging services using SCCP protocol. The benefit is that Cisco Unified Communications Manager users will gain access to more features during fallback ****without any additional licensing costs.
Comparison of Cisco Unified SRST and
Cisco Unified CME in SRST Fallback Mode
Cisco Unified CME in SRST Fallback Mode
â¢ First supported with Cisco Unified CME 4.0: Cisco IOS Software 12.4(9)T
â¢ IP phones re-home to Cisco Unified CME if Cisco Unified Communications Manager fails. CME in SRST allows IP phones to access some advanced Cisco Unified CME telephony features not supported in traditional SRST
â¢ Support for up to 240 phones
â¢ No support for Cisco VG248 48-Port Analog Phone Gateway registration during fallback
â¢ Lack of support for alias command
â¢ Support for Cisco UnityÂ® unified messaging at remote sites (Distributed Exchange or Domino)
â¢ Support for features such as Pickup Groups, Hunt Groups, Basic Automatic Call Distributor (BACD), Call Park, softkey templates, and paging
â¢ Support for Cisco IP Communicator 2.0 with Cisco Unified Video Advantage 2.0 on same computer
â¢ No support for secure voice in SRST mode
â¢ More complex configuration required
â¢ Support for digital signal processor (DSP)-based hardware conferencing
â¢ E-911 support with per-phone emergency response location (ERL) assignment for IP phones (Cisco Unified CME 4.1 only)
Cisco Unified SRST
â¢ Supported since Cisco Unified SRST 2.0 with Cisco IOS Software 12.2(8)T5
â¢ IP phones re-home to SRST router if Cisco Unified Communications Manager fails. SRST allows IP phones to have basic telephony features
â¢ Support for up to 720 phones
â¢ Support for Cisco VG248 registration during fallback
â¢ Support for alias command
â¢ Lack of support for features such as Pickup Groups, Hunt Groups, Call Park, and BACD
â¢ No support for Cisco IP Communicator 2.0 with Cisco Unified Video Advantage 2.0
â¢ Support for secure voice during SRST fallback
â¢ Simple, one-time configuration for SRST fallback service
â¢ No per-phone emergency response location (ERL) assignment for SCCP Phones (E911 is a new feature supported in SRST 4.1)
http://www.cisco.com/en/US/prod/collateral/voicesw/ps6788/vcallcon/ps2169/prod_qas0900aecd8028d113.html
These SRST hardware based restrictions are very similar to the number of supported phones with CME. Here is the actual breakdown;
Cisco 880 SRST Series Integrated Services Router
Up to 4 phones
Cisco 1861 Integrated Services Router
Up to 8 phones
Cisco 2801 Integrated Services Router
Up to 25 phones
Cisco 2811 Integrated Services Router
Up to 35 phones
Cisco 2821 Integrated Services Router
Up to 50 phones
Cisco 2851 Integrated Services Router
Up to 100 phones
Cisco 3825 Integrated Services Router
Up to 350 phones
Cisco CatalystÂ® 6500 Series Communications Media Module (CMM)
Up to 480 phones
Cisco 3845 Integrated Services Router
Up to 730 phones
*The number of phones supported by SRST have been changed to multiples of 5 starting with Cisco IOS Software Release 12.4(15)T3.
From this excellent doc;

Best Practice for Extracting a Single Value from Oracle Table

I'm using Oracle Database 11g Release 11.2.0.3.0.
I'd like to know the best practice for doing something like this in a PL/SQL block:
DECLARE
    v_student_id    student.student_id%TYPE;
BEGIN
    SELECT student_id
    INTO    v_student_id
    FROM    student
    WHERE   last_name = 'Smith'
    AND     ROWNUM = 1;
END;
Of course, the problem here is that when there is no hit, the NO_DATA_FOUND exception is raised, which halts execution. So what if I want to continue in spite of the exception?
Yes, I could create a nested block with EXCEPTION section, etc., but that seems clunky for what seems to be a very simple task.
I've also seen this handled like this:
DECLARE
    v_student_id    student.student_id%TYPE;
    CURSOR c_student_id IS
        SELECT student_id
        FROM    student
        WHERE   last_name = 'Smith'
        AND     ROWNUM = 1;
BEGIN
    OPEN c_student_id;
    FETCH c_student_id INTO v_student_id;
    IF c_student_id%NOTFOUND THEN
        DBMS_OUTPUT.PUT_LINE('not found');
    ELSE
        (do stuff)
    END IF;
    CLOSE c_student_id;
END;
But this still seems like killing an ant with a sledge hammer.
What's the best way?
Thanks for any help you can give.
Wayne

Do not design in order to avoid exceptions. Do not code in order to avoid exceptions.
Exceptions are good. Damn good. As it allows you to catch an unexpected process branch, where execution did not go as planned and coded.
Trying to avoid exceptions is just plain bloody stupid.
As for you specific problem. When the SQL fails to find a row and a value to return, what then? This is unexpected - if you did not want a value, you would not have coded the SQL to find a value. So the SQL not finding a value is an exception to what you intend with your code. And you need to decide what to do with that exception.
How to implement it. The #1 rule in software engineering - modularisation.
E.g.
create or replace function FindSomething( name varchar2 ) return foo.col1%type is
id foo.col1%type;
begin
select col1 into id from foo where col2 = upper(name);
return( id );
exception when NOT_FOUND then
return( null );
end;
And that is your problem. Modularisation. You are not considering it.
And not the only problem mind you. Seems like your keyboard has a stuck capslock key. Writing code in all uppercase is just as bloody silly as trying to avoid exceptions.

Best practice for use of spatial operators

Hi All,
I'm trying to build a .NET toolkit to interact with Oracles spatial operators. The most common use of this toolkit will be to find results which are within a given geometry - for example select parish boundaries within a county.
Our boundary data is high detail, commonly containing upwards of 50'000 vertices for a county sized polygon.
I've currently been experimenting with queries such as:
select
from
uk_ward a,
uk_county b
where
UPPER(b.name) = 'DORSET COUNTY' and
sdo_relate(a.geoloc, b.geoloc, 'mask=coveredby+inside') = 'TRUE';
However the speed is unacceptable, especially as most of the implementations of the toolkit will be web based. The query above takes around a minute to return.
Any comments or thoughts on the best practice for use of Oracle spatial in this way will be warmly welcomed. I'm looking for a solution which is as quick and efficient as possible.

Thanks again for the reply... the query currently takes just under 90 seconds to return. Here are the results from the execution plan ran in sql*:

The wards table has 7545 rows, the county table has 207.
We are currently on release 10.2.0.3.
All i want to do with this is generate results which fall in a particular geometry. Most of my testing has been successful i just seem to run into issues when querying against a county sized polygon - i guess due to the amount of vertices.

Best practice for backing bean population? (also, ActionListener RANT)

Hello,
I am about 3/4 of the way through development of a small to medium size JSF application. Sometimes I really like JSF, but much of the time I am left puzzled or frustrated for hours trying to find workarounds to JSF's bugs/glitches and design flaws.
For example, early on, I was impressed with how easily it was to invoke a method from a page using an actionlistener. Now that I'm actually building things with JSF, the actionlistener funtionality still seems cool, but incredibly half baked. I find myself using request parameters LIKE CRAZY to work around the fact that JSF doesnt support passing parameters directly to backing bean methods. This feels awkward and wrong considering the fact that JSF is intended to abstract the HTTP underpinnings. To add insult to injury, I often have to iterate through ALL of the request parameters looking for one that has an id with an ending matching my desired property name (since JSF appends it's own crap to the beginning). I don't like doing things in a hacky way. This seems very hacky, and I feel dirty doing it.
So, my first question is, what is the best practice for populating backing beans??? How do others accomplish this. I can think of several other approaches, but none feel less hacky.
Second, are there plans in the next spec (please say there are) to allow parameters to be passed to backing bean methods? If not, WHY THE HECK NOT?
Even though JSF expert group people have been conspicuously absent from this forum of late, I'd really appreciate responses from you as well.
Thank you for your thoughts.

Hi BrownBear,
I've been using JSF for about 6 months now and I'd be glade to help as much as I can.
Concerning parameters, I'm not sure what your issue is but I use the f:param tag to pass them. If you could post an example of what you are trying to do, I could see exactly what your issue is. Maybe the f:param can't help you.
As for best practice for populating backing beans, I personaly try to let JSF do as much as possible. For example, if I have a backing bean with five properties, I make sure that they all are on the JSP page the bean serves. If one of the property is just there as an Id like, lets say, a Person ID (DB row key), then I put it on my JSP page as a hidden input field. I do the same with the properties that only for display, if I want them to be back in my bean when request comesback.
Hope this help some how. Please, feel free to ask specific questions related to your specific problem and I monitor this post and trnasfer to you the ;little JSF experience I have.
I'm pretty happy with JSF as it is but it sure needs improvements. :) What the heck, it's version 1.01 after all, and the next release should be a great one with the integration of JSTL.
Cheers

Best practices for loading swf's

Greetings,
Using CS5 AS2
I'm creating a website in flash (all the files will be in one directory/folder on SharePoint) and want to make sure that what seems to be working fine is best practice.
I have an index.swf with many buttons which will take the user to landing pages/content/other swfs. On these different buttons I have the script...
on (release) {loadMovieNum("name.swf", 0);} I could also do just {loadMovie("name.swf", 0);} ??
The movie transitions nicely to name.swf and on this page I have a button that returns the user to the index.swf...
on (release) {loadMovieNum("index.swf", 0);} Things move back to index.swf nicely and user can chose to go to another landing page.
It looks like I'm on the right track, bc nothing is going awry? but want to check. Am I following best practices for moving from one swf to another within a website?
Thanks for help or confirmation!!

loading into _level0 (and you should use loadMovieNum, not loadMovie, when loading into a level) undermines some of the benefits of a flash application: all the assets must load with each display change and the user sees a flash instead of appearing to transition seamlessly from one display to the next.

Best Practice for Servlets

I guess I'm asking for most peoples' input on what I'm planning to do here ....
Here's what I want to do, and know a bit about.
o I want to make a servlet that serves only XML.
o After that, I want to transform the XML into web pages, RSS feeds etc.. using XSLT.
Here's what I'm not so sure about...
o How should I implement the interface to the web-based aspects? Should the servlet be coded to display HTML pages on "GET" requests? Or should I use a pile of HTML files to make forms?
o What do I use to perform the XSLT transformations? Where should the set of solutions be placed relative to my servlet? Would a user then access this solution rather than the servlet itself?
o How do I code the servlet on one machine, and then test it on another without breaking the libraries? How do I set up any libraries I might have to use (like for XSLT transformations) on the server?
Any other advice here? I'm sure this is done often, but I can't find a resource that explains the best practices for it all.
I know this sounds like a lot of stupid questions. I've had lots of programs working with Java before, but I'm at a loss as to how I'm supposed to package libraries I use in my programs - moreso with a servlet. To make matters worse, I plan on using MySQL as the database.
If there's some wizard on the forums here who's willing to say more than just "RTFM" (of which there is none to answer my questions together as one), I'd be very very happy ":^)

Let me re-pose my question so as to be specific
enough to not be picked apart in my answer.
I want to FIRST AND FOREMOST, create a servlet that
serves up XML based on parameters given to it (how?
who cares.).What does "serves up XML" mean?
Let's be precise. Do you intend the servlet to send the XML back to the client? Or is the XML an intermediate step in your processing? (Yes, it matters.)
Then, I want to create interfaces (HTML, RSS,
boogledeedoo) to this XML data by having either JSP,
another servlet or insert something else here,
transform the XML into whatever the desired format
is."interface" is a loaded term in Java. What do you mean by it?
>
My assumption is that I'll make the servlet that is
capable of outputting my desired XML data and then
create another servlet that will poke it for data as
needed to transform the XML into HTML. This servlet
would also likely serve as the web site itself and
would manage user logins etc...(persistance yaddy
yadda)You're not thinking about this properly.
"yadda yadda" == muddled thinking.
My other assumption is that I'll make another servlet
that will poke the XML servlet and transform that
into RSS or anything else I can dream up.How does "poke the XML servlet" fit into the request/response protocol that is HTTP? Please explain.
-=-!REASONING!-=-
Previously, when I was working with PHP, I liked to
make scripts that would display interfaces and post
to themselves. OK, now I see. "interface" == GUI in a browser to you. Very good.
You can create a JSP that is an interface. You can have that JSP submit the HTTP POST or GET request to itself. No problem there, as long as "itself" knows what to do with the request.
It was a nice way of creating a
complete little package. Everything for one function
was encapsulated nicely under one roof. No excessive
HTML files all over the place to nurture.A simple problem, a simple solution. You can do that with a JSP.
Look. Part of my inability to describe this well is
because I DO feel like I'm in a lot of directions at
once. Or you don't understand the technology very well.
But I have to be in order to pull together
some sort of plan for myself. I understand many
concepts and have just finished studying object
oriented design etc..."Just finished"? How long did it take?
I know things about how Tomcat does connection
pooling for SQL connections.Great. Not much to understand there. It's harder to figure out how to do n-tier apps with more than one page well.
I do know how to use Google, probably a lot better
than most. But rest assured, I've yet to find a
little guide as complete as any of the "LAMP" books
there are out there. Which by the way, I have never
purchased.That's because Java Enterprise Edition isn't intended for little problems. LAMP is. Maybe the limitation is that you are used to "little" problems and not bigger ones.
If JEE seems scattered and complex, it's because it is. It encompasses more than LAMP.
I'm confident in good guidance, and not a heartfelt
smackdown. I'm still waiting for some clear suggestions.I gave you one, you just didn't know it: go read about Spring.
http://www.springframework.org
It'll help you structure complex apps from the user interface to the database in the back.
You're welcome.
