Is this a best practice of BAM implementation?

Hello everyone:
Currently we have done an Oracle BAM implementation. To explain briefly our implementation:
We have an Oracle Database 8.1.7, were all transactions are recorded. We tried using JMS to import the data into data objects in the Oracle BAM respository. We did this by using a database link to a Oracle Database 10G and then through Advanced Queueing. This did not work due to performance issues. The AQ messages were not consumed as fast as they were produced, so there was no real time data.
Then we developed a Java component to read the table in the Oracle Database 10g and started using batch upserts into the Oracle BAM through the web services API provided. This solved the performance issue mentioned above.
Currently we are using all the data procesing in the Oracle 10G database through PL/SQL stored procedures, data mining is applied on the transactions and the summary information is collected intro several tables. This tables are updated and then imported into the Oracle BAM data objects.
We have noticed, that Oracle BAM has some performance issues when trying to view a report based on a data object with large number of records. Is this really an issue on Oracle BAM? The average number of transactions is 200,000 records. How can we solve this issue?
Another issue we want to expose is. When viewing reports through the browser, and the browser hangs or suddenly closes. Sometimes the Active Data Cached Feed window hangs or doesn´t close. When this happens, an we try to open another report, the report never displays. Is this a browser side issue or server side issue?
The Oracle BAm is installed on a Blade with 2X2 Xeon Procesors (4 cpus), 16GB RAM and Windows Server 2003 Enterprise Ed. with SP2.
How can we get a tuning guide based on best practices?
Where can we get suggestions about our implementation?
Thanks to anyone who can help us.

Even i am facing similar issue. Any pointers would be appreciated.
Thanks.

When I share a file to YouTube, where does the output file live? I want also to make a DVD. And is this a best practice or is there a better way?

I want also to make a DVD, but can't see where the .mov files are.
And is this a best practice or is there a better way to do this, such as with a master file?
thanks,
/john

I would export to a file saved on your drive as h.264, same frame size. Then import that into youtube.
I have never used FCP X to make a DVD but I assume that it will build the needed vob mpeg 2 source material for the disk.
I used to use Toast & IDVD. Toast is great.
To "see" the files created by FCP 10.1.1 for YouTube, rt. (control) click on the Library Icon in your Movies/show package contents/"project"/share.

Best Practice for Apex Implementation

Hello,
I'm looking for some guidance in best practices on implementing Apex across our enterprise. Do we install it on many databases based on whether an application gets most of its data from that database? And if so, could we use one 10gAS web server to serve up all of the instances?
We currently have Apex installed on RAC databases in each environment (Dev, Int, QA, Prod), and then use dblinks to connect to the many remaining databases. Each RAC environment then uses an appropriate 10gAS web server (one web server per Apex installation). I'm wondering if this is a good approach or not? Any suggestions are appreciated.

Toy Store Best Practice: How to implement 'cancel' for register user page

Let's say user wants to register or (even edit) his/her account. But when forwards to register(edit) account page, he/she decides not to do it. I would like to implement 'cancel' button and return the user whereever he/she was before comming to this page.
What is the best practice?
Even worse, if user gets to this page and never saves the entry. The model would be dirty. And then let's say that user wants to commit something in DB, it may commit incorrect(blank) entry for created row. What I am up to, is what is the best practice to keep track if the model gets dirty and delete invalid rows in general?

You might want to read this thread:
Cancel operation followed by refresh raises JBO-33035

Best practices for Indirection implementation?

Hi, I'm about to start trying out several aspects of indirection in Toplink. My question is; what are best practices to implement this feature?
To me, it looks like proxy indirection is the cleanest way to do this, I'm not sure however whether there are any restrictions to it - besides the necessity for an interface for each domain class. My goal is to keep the amount of Toplink code 'clutter' in my domain model as low as possible.
Thanks.

Although proxy indirection is nice for 1:1 as it reduces the 'clutter' there may be a performance hit. It really depends upon your JDK.
Personally I prefer to use ValueHolder for 1:1 and transparent collection indirection for my collection mappings. The attribute that you make a ValueHolder is private and the API of your class does not need to expose its existence in any way. I find this best as I do not need to manage an additional interface and keep its API in sync.
In the very near future you will be able to use our EJB 3.0 implementation that leverage AOP style weaving to dynamically enhance your mapped classes during loading. This will allow you to have 1:1 indirection without the interface or ValueHolder. Since changing the type of the attribute and the implementation of the get/set method is probably less intrusive then factoring our an unecessary interface to your future migration I would stick with the ValueHolder for now.

Best Practice for UPK implementation

We will start using UPK tool in our Oracle E-Business Suite (11.5.10) environment soon.
We are in a process of configuring the tool and making a standard template for training documents.
For example, which screen resolution? which font size and color, bubble icon, pointer position, task bar setting, and etc.
If anyone have any best practice document to share, I will appreciate it.

Best practice question for implementing a custom component

I'm implementing a custom component which renders multiple <input type="text" .../> controls as part of it. The examples I've seen that do something similar use the ResponseWriter to generate the markup "by hand" like:
     writer.startElement("input", component);
     writer.writeAttribute("type", "text", null);
     writer.writeAttribute("id", "foo", null);
     writer.writeAttribute("name", "foo", null);
     writer.writeAttribute("value", "hello", null);
     writer.writeAttribute("size", "20", null);
     writer.endElement("input");
I don't know about anyone else, but I HATE having to write code that manufactures this stuff - seems to me that there are already classes that do this, so why not just use those? For example, the above could be replaced with:
     HtmlInputText textField = new HtmlInputText();
     textField.setId("foo");
     textField.setValue("hello");
     textField.setSize(20);
     // just to be safe, invoke both encodeBegin() and encodeEnd(),
     // though it seems like encodeEnd() actually does the work in this case,
     // but who knows if they might change it at some point
     textField.encodeBegin(context);
     textField.encodeEnd(context);
So my question is, why does everyone seem to favor the former over the latter? Why not leverage objects that already do the (encoding) work for you?

Got it!
You JSP should have this:
<h:panelGroup styleClass="jspPanel" id="jspPanel1"></h:panelGroup>
And your code page ValueChangeListener/ActionListner should have this:
          if (findComponent(getForm1(),"myOutputText") == null)
               FacesContext facesCtx = FacesContext.getCurrentInstance();
               System.out.println("Adding component");
               HtmlOutputText output =
                    (HtmlOutputText) facesCtx.getApplication().createComponent(
                         HtmlOutputText.COMPONENT_TYPE);
               output.setId("myOutputText");
               output.setValue("It works");
               getJspPanel1().getChildren().add(output);
               System.out.println("Done");
               DebugUtil.printTree(FacesContext.getCurrentInstance().getViewRoot(),System.out);
          else
               System.out.println("component already added");
I just have to figure out this IOException on the closed stream - probably has to do with [immidiate="true"].
Thanks.

Best Practice for Package Implementation of Data Manipulation

Hi,
Would like to ask which is better implementation for data manipulation (insert, update, delete) stored procedure for a single table.
To create a single procedure with input parameter for the action such as 1 for insert, 2 for update and so on
or
to create separate procedures for each like procedure pInsData for insert, pUpdData for update...

Hi,
Whenever you create a procedure it resides as a seperate object in database.
In my opinion its better to create a single procedure which takes care of all DML concern to a table, rather than creating different procedures for each DML.
If your number of DML are more and interrelated then its better to create a package and put all related DML procedures in the package concern to one transaction or table. This is because whenever you will call a package entire package will be placed in the memory for a particular session. So if you create different procedures for DML then you need to call the procedures each time you want it to be executed.

When I delete files on a USB, it doesn't free up memory on the stik. I find I have to empty the entire stik, use Disk Utility to 'erase' it, then transfer back the files I removed to free up all the space on the stik. Is this the best practice?

It frustrates me that if I delete a file from a USB, it doesn't free up the memory on the stik. I have been removing all the files from the stik, opening Disk Utility and erasing the empty USB. That frees up the entire stik. Then I have been transferring back the files I removed from the stik. The result is that I have memory available to use again. It seems to me this is an unnecessarily complicated and time consuming way to get the result. Is there a shorter way to do this?

Hello Horst,
Thank you for the question. Have you been emptying your trash after deleting the items? For the item to be removed from your USB device, you will need to empty the trash on your MacBook Pro after you delete the items, as described in the featured discussion below. Your USB device will still need to be connected when you do this:
Choose Empty Trash from the Finder menu. Unlike Windows, the trash needs to be emptied manually for any drive other than one mounted through the network.

ESS Implementation Best Practice

I am implementing the latest version of Portal on Netweaver 7.0. When the business package is loaded onto the server, I get a folder in PCD at Portal Content > Content Provided by SAP > End User Content > Employee Self-Service.
I'm curious what the best practice is for implementing any changes to the content in that folder. Should I copy the entire folder into my own folder in the PCD (by where all my BI objects are for example) and then make the changes I need? If I do that and we later upgrade, will these objects be updated? Or is the best thing to do just copy the ones I'm going to make slight changes to and have everything still referencing back to the "Content Provided By SAP" folder?
Any help would be appreciated.

Hi,
Create a new folder and copy the PCD objcets you want as a delta link. This way you changes will be preserved without impacting the original objects. Then if you upgrade, the new objects will inherit the new features into your delta link.

Best Practice for Production environment

Hello everyone,
can someone share the best practice for a production environment? or is there a SAP standard best practice to follow in a Production landscape?
i understand there are Best practices available for Implementation , Migration and upgrade. But, i was unable to find one for productive landscape
thanks.

Hi Siva,
What best practise are you looking for ? If you can be specific on your question we could provide appropriate response.
From my basis experience some of the best practices.
1) Productive landscape should have high availability to business. For this you may setup DR or HA or both.
2) It should have backup configured for which restore has been already tested
3) It should have all the monitoring setup viz application, OS and DB
4) Productive client should not be modifiable
5) Users in Production landscape should have appropriate authorization based on SOD. There should not be any SOD conflicts
6) Transport to Production should be highly controlled. Any transport to Production should be moved only with appropriate Change Board approvals.
7) Relevant Database and OS security parameters should be tested before golive and enabled
8) Pre-Golive , Post Golive should have been performed on Production system
9) EWA should be configured atleast for Production system
10) Production system availability using DR should have been tested
Hope this helps.

Deepak Kori

Best Practice - Changing description for Org Unit/Position or creating new?

Hello Freinds,
I just want to know from your experience what's normally practiced in your implementations for OM :-
For scenarios where there is a need to change the description of a particular org unit or position, do u
1. just change the description effective a particular date (to maintain history) or
2. put an end date to those objects and create new ones ?
Solution 1 is quick and easy, but in IT0001 the description displayed is as on start date of that infotype which is normally a date prior to the change in desc of those objects. As a result this infotype keeps displaying old description.
Is there any way to change this display to show the current description instead of the description as on start date of this infotype ???
Solution 2 calls for a lot of related activities, say if i create a new org unit and delemit the old one - then i have to move all the sub org units and positions into this new one ... which is quite time consuming and doesn't really seem practical.
How do u manage such scenarios ?
Thanks
Allen

We use option #1, although I am not sure this is best practice. Using option 1 for positions makes it challenging when it comes to reporting on length of time in position. We frequently have the scenario where a person is reorged not because they applied for another position, but just because the big wigs want to move around the chess pieces. In these cases we simply modify the position attributes and then run a PA action. Then if you run a query and use the standard delivered Length of time in position field, it appears as if the person has been in the same position for years (which they have), but their position has been retitled, re-graded, and re-orged numerous times. This makes it very difficult to get to an employee's length of time in their role.
This is a great discussion question I hope more people respond with what they do and why.

What is best practice for using Maintenance Optimizer to download SPS + EhP

SAP indicates in note 1095233 and many other documents that the best practice is to implement an EhP along with an SP Stack in the same queue. Furthermore, the only way to download the components of an EhP is via Maintenance Optimizer. However, in step 2 (Calculate download files automatically) you must choose either Maintenance (SPS) or Enhancement Package Installation (EhP); there is no way to tell Maintenance Optimizer that you want to download both SPS and EhP.
In developing the process for my team I circumvented the problem by saying to select Maintenance first to get the SPS into the Download Basket and follow that with selecting Enhancement Package Installation to get the EhP into the Download Basket. The plan would be to include all the downloads in the SPAM/SAINT queue with the expectation that SPAM/SAINT will be able to determine what must be included.
I'm wondering now whether that is a legitimate way to approach this and I am hoping others will share their process.
Thanks,
Terry McCann

Actually, I don't believe you will get the entire SP Stack for ERP 6, you only get those pieces of the stack that are required for the Technical Usages you select for the EhP. I'm basing that on my observation that you get a different subset of the files making up the stack depending upon your TU selection. Also, note 1095233 specifically states:
If now the corrections included in the enhancement package 3 correspond to ERP 6.0 SP level 11, SAP recommends to update also the parts of your system to SP level 11 which you do not want to update to enhancement package 3 to achieve a consistent correction level in all parts of your application: SAP recommends to update all software components to the correction status corresponding to SAP ERP 6.0 Support Package Stack 11 with the installation of SAP enhancement package 3 for SAP ERP 6.0.
Thanks,
Terry

Is this a best practice of BAM implementation?
