How to use local database for Education Portal

Hi All,
We are implementing a Education Portal (learning Solution) and here are our requirements
1. Course details are stored in R/3 portal
2. When users login to the education portal, course catalog should be displayed with all the details and here the course catalog should not be displayed directly from R/3.
3. course catalog should be read from some local database or XML ( how to update the local database/ XML from R/3 data periodically)
4. Once when user sees the course details, if he wants to buy the course, he will register and do the payment.
5. User details should be stored in the local database and only if he do the payment and his registration details will be stored in the R/3.
Is any one have any idea how to go ahead with the above function and give some inputs.
Regards
Ponnusamy

Hi,
Basically, you would have to use plain JDBC / Open SQL or some persistence framework on top of it (e.g. JPA if you're on Java EE 5 / NW CE 7.1, or EJB CMP, JDO, Hibernate with previous NW releases) to store and load data in the local DB. For updating the backend ("R/3") you would use SAP JRA which is based on SAP JCo.
Search for these terms on help.sap.com and you will find plenty of information about it.
HTH!

AAA Authorization Using Local Database

Hi Guys,
I'm planning to use AAA authorization using local database. I have read already about it, I have configured the AAA new-model command and I have setup user's already. But I'm stuck at the part where I will already give certain user access to certain commands using local database. Hope you can help on this.
FYI: I know using ACS/TACACS+/RADIUS is much more easy and powerful but my company will most likely only use local database.

For allowing limited read only access , use this example,
We need these commands on the switch
Switch(config)#do sh run | in priv
username admin privilege 15 password 0 cisco123!
username test privilege 0 password 0 cisco
privilege exec level 0 show ip interface brief
privilege exec level 0 show ip interface
privilege exec level 0 show interface
privilege exec level 0 show switch
No need for user to login to enable mode. All priv 0 commands are now there in the user mode. See below

For Working offline - Which one to use - local database caching or reliable messaging?

Hi,
I am working on a mobile application with lcds where there is a feature to be implemented. The user can use the application in airplane mode and be able to automatically send requests to server when he comes online. After some research, I found that I have to use a feature in the documentation called ocasionally conencted clients, which uses local database with dataservice.savecache() and offline adapter. I also found another feature called reliable messaging which takes care of sending the pending requests when the user comes online, but not sure if this feature supports offline mode for longer periods. The documentation mentioned that reliable messaging is only good for transient network disconnects, meaning disconenction for shorter time.
Can anybody please confirm which is the right feature that best suits this requirement?
Thanks,
Swathi.

Hi Ashish,
Thank you so much for the resource. One more question, The code in the resource link, has calls to Dataservice.disconnect() and Dataservice.connect() on the buttons. If my user need not bother to click on those buttons for connections and just set his phone to airplane mode and start working, I am using SocketMonitor class to monitor for network connection and then perform the Dataservice.connect(). In that case, I have problems when network is connected, the data service seems connected automatically some times and not connected other times resulting in errors. I am using autoConenct = true. How can I handle this? Do I have to call disconnect when socket is not available and then call conenct when it is available, things like that? Or Is there any other way to implement this without using SocketMonitor class?
Thanks,
Swathi.

How to use Logical database in function module?

I will create a function module in HR.
but how to use Logical database in function module ? Logical database PNP always show screen.in function (RFC) code , it is a matter.

You cannot attach the LDB to the main program of the function group.
- So you may [SUBMIT|https://www.sdn.sap.com/irj/sdn/advancedsearch?cat=sdn_all&query=submit&adv=false&sortby=cm_rnd_rankvalue] a report which use the LDB and get back the data (export/import), by default in the syntax of SUBMIT the selection-screen will not be displayed
- Use [LDB_PROCESS|https://www.sdn.sap.com/irj/sdn/advancedsearch?query=ldb_process&cat=sdn_all], fill a structured table for selection, and get data back in another table
- Use [HR function modules to read Infotypes|https://www.sdn.sap.com/irj/sdn/advancedsearch?cat=sdn_all&query=hrfunctionmodulestoread+Infotypes&adv=false&sortby=cm_rnd_rankvalue].

I want to use Berkely database for my Dissertation

Hello everyone,
I am having some doubts regarding Berkely database. Actually, I am using this database for my project. The scenario of the project is, I have developed some business rules depending on the concept of Ripple Down Rules and represented the rules using Conceptual graphs. Now I want to store fire these business rules in to the Berkely database, so that my application can use these business rules from the Berkeley database.
This is the context of my project. But, I am very new to this Berkely database. I have downloaded the Berkely database from the Oracle website and also installed it. The OS is am using is Windows XP SP2. Can anyone explain me how to store Conceptual graphs in a Berkely database.
I am really a beginner to Berkely database. i don't even know what to do after installing the Berkely database. Please advise me about this.
I would be very thankful to you.
Cheers,
Phani.

Hi Phani,
The simple answer is however you want. Berkeley DB doesn't put any constraints on how you store data in it. Its main purpose is to provide an efficient and scalable key/value storage and retrieval system, upon which you can build your own data storage system.
More specifically, if you're representing graph data, the simplest way to do so is with the "edge list" paradigm. You could, for example, set up a pair of databases, one to store all your graph nodes (with associated metadata) and one for directed edges. I'm not sure what particular c structures you'll want to use for these, but I'd suggest using record numbers on both the nodes and the edges DBs, unless all your nodes have unique and meaningful names. I'd also allow duplicate records on your edges DB, and have a very simple record structure in it that simply maps from a source node id to a destination node it (the duplicates allow multiple edges from a given node.)
If you have more specific constraints on your graph and algorithms you'd like to run on it, there are potentially more schemes you could use, such as the nested set representation for trees, and so on.
Hope this helps,
Daniel

How to use temporary database?

hi
i am using timesten as cachedb for oracle database。i have some problem about how to use temporary database？
1） what's the difference between temporary and non-temporary database，if i use awt cache group,then timesten will automatically replicate all change to oracle database , even if timesten crashed，i can set up another timesten quickly，no data loss？
2）since all data is in oracle database，does timesten‘s transaction log and checkpoint file useful ? does timesten need backup ?

Temporary databases have very limited usefullness; you can't use them with replication or caching for example. They are a very 'niche' use case; I'd recommend that you avoid them for mainstream use.
TimesTen checkpoiint and transaction log files are always required (except for Temporary database which do not have checkpoint files but do have log files).

Why and how we use Logical Database?

Can anybody explain with example why and how we use logical database?
Regards,
Rajan

Hello,
SAP comes loaded with all the extras. Among the extras that are most helpful to IT managers are all the access routines needed to pull any business object that managers can think of out of SAP databases. However, SAP has not thought of everything where your particular applications are concerned. SAP organizes its standard database tables to service business units based on conventional business applications. Itu2019s likely your business requires something new, perhaps even something exotic. In that case, you will need to create a new database, using information from different places. Basically, you need a logical database. You need to create a virtual business data object repository consisting of a new kind of record or table that suits your purposes. In addition, the repository should be composed of information that is actually stored in a number of different locations, none of them necessarily logically associated with one another. Letu2019s take a closer look at creating logical databases.
A case for a logical database
Suppose my company manufactures widgets of the most obscure variety, and they are components of other widgets. I sell my widgets as raw material for the more sophisticated widgets built by others, but in some cases I actually partner with other manufacturers in creating yet another class of widget. Now, in my world, I consequently have customers who are also partners. I sell to them and I partner with them in manufacturing and distribution. Also, I need an application that uses both of these dual-use relationships.
Essentially, I have a customer database and a partner database. Neither contains records that are structured to contain the identifying particulars of the other. Thus, I need a hybrid database that gives me tables detailing these hybrid relationships. What can I do? I can go the long way around and write a new database, pulling information from both and creating new objects with a customized program that I write by hand. However, this process is cumbersome and contains maintenance issues. On the other hand, I can use SAPu2019s logical database facility, create my logical database in a couple of minutes, and have no maintenance issues at all.
Logical database structures
There are three defining entities in an SAP logical database. You must be clear on all three in order to create and use one.
u2022     Table structure: Your logical database includes data from specified tables in SAP. There is a hierarchy among these tables defined by their foreign keys (all known to SAP), and you are going to define a customized relationship between select tables. This structure is unique and must be defined and saved.
u2022     Data selection: You may not want or need every item in the referenced tables that contributes to your customized database. There is a selection screen that permits you to pick and choose.
u2022     Database access programming: Once youu2019ve defined your logical database, SAP will generate the access subroutines needed to pull the data in the way you want it pulled.
Creating your own logical database
ABAP/4 (Advanced Business Application Programming language, version 4) is the language created by SAP for implementation and customization of its R/3 system. ABAP/4 comes loaded with many predefined logical databases that can construct and table just about any conventional business objects you might need in any canned SAP application. However, you can also create your own logical databases to construct any custom objects you care to define, as your application requires in ABAP/4. Hereu2019s a step-by-step guide:
1.     Call up transaction SLDB (or transaction SE36). The path you want is Tools | ABAP Workbench | Development | Programming Environment | Logical Databases. This screen is called Logical Database Builder.
2.     Enter an appropriate name in the logical database name field. You have three options on this screen: Create, Display, and Change. Choose Create.
3.     Youu2019ll be prompted for a short text description of your new logical database. Enter one. Youu2019ll then be prompted to specify a development class.
4.     Now comes the fun part! You must specify a root node, or a parent table, as the basis of your logical database structure. You can now place subsequent tables under the root table as needed to assemble the data object you want. You can access this tree from this point forward, to add additional tables, by selecting that root node and following the path Edit | Node | Create. Once youu2019ve saved the structure you define in this step, the system will generate the programming necessary to access your logical database. The best part is you donu2019t have to write a single line of code.

Hi Any body Knows How to use CAT Tool for Up Loading?

Hi
If any body knows how to use CAT Tool for up loading transactions, explain the steps.
Our requirement is, we want to up load transactions like Oppor , Quotation,Order etc...we want to up load these transcations from Local system to CRM Server
how to do this? Let me know the steps.
Regards
Venkat

If you have 10,000 or less, CATT is a reasonable method, but I would suspect that you have far more than that if you're needing to load transactions.
LSMW is probably a better way to go if you have more than 10k, but I am not familiar with LSMW

How to use time capsule for wireless back-up but not internet?

Hello,
I have a tower and recently a laptop at work. The tower is connected to our local network with an ethernet cable and the laptop with wireless. So, the internet connection is fine for both.
I was hoping to use my time capsule to do time machine backups on my laptop. Do you have any advice on how to configure this? I do not want to use the time capsule to extend my Internet, as I believe my work I.T. would prefer to handle all access to their network.
Perhaps there is some documentation about doing this that you could point me to? I have not been able to find it.
Thank you for your help.

Your original question was How to use Time Capsule for wireless back-up but not Internet?
There is no reason for you to connect the tower....or anything else...using Ethernet if your goal remains that same as you stated.
If you are asking if you can backup the Tower using Ethernet, and not wireless, then you can connect the tower to one of the LAN <-> ports on the Time Capsule....not the WAN port.
Yes, it appears to work without plugging into my tower.
Correct, it will work.
I just have to select the network that it created. Of course, I have no access to the Internet while this is happening and it can not auto backup, unless I am on that wireless signal.
As I stated, that is the downside to trying to back up without an Internet connection. You have to establish another network...and backup over that network.
If you are asking if you can stay connected to the work network while also backing up to your non-Internet "private" network, that is not possible.

How to use same actions for differ pop-up

Hi gurus,
I am using 2 popup in a view.same popup's having same buttons 'Yes', 'No'.when i use 1st one i have to create an action for that Yes button where i put my code for that particular Action.
But when i used 2nd one the action define for that is not acceptable with differ name.it takes only standard one.
Now my Query is : How to use same actions for differ pop-up buttons with in a similar view?Where i put my code.
Plz sugges me.
<b>Points will be sured.</b>
Sanket sethi

Hi,
Take one integer value attribute in the context of view
when you r performing action on POP1 set it's value to 1
when you r performing action on POP2 set it's value to 2
create one method which receives integer argument, say diaplay(int a)
In the action call display(wdContext.currentContextElement().get<intvariable>()) by passing the value in the context attribute
in display() method, Check the value of integer variable..
if it is 1 then perform action related to POP1
if it is 2 then perform action related to POP2

How to use Web Serivce for not jsr 172 phone

Hi:
Is anyone know, how to use web service for phones that only have standard J2ME package installed (without jsr 172 web service packagenstalled)?
thank you

Hi,
I think you need to write the code for this from scratch (built on top of existing HTTP functionality). There may be open-source J2ME code you could use. I've never tried this so I'm afraid I don't know any more. But maybe that is what you were asking... i.e. does anyone have code that does this already...
