OM interfaces and Migration strategy

Hello,
What can be the interfaces for OM? What kind of interfaces?
Can someone please throw some light on interfaces and the migration strategy of OM data apart from BDC and LSMW.
Cheer's....

Sammer
I feel LSMW is the Best way as you know what are the inputs which are giving in the Template and how it is getting Uploaded
for OM Data upload
you have to upload 1.Objects First 2. Relationships of that objects
and lets wait for other expert views

Dunning by dunning procedure and collection strategy

Hi All,
Have some questions around dunning.
1. Can dunning by dunning procedure and collection strategy coexist in the same company code - if this cannot be achieved by config can it be achieved by development - can we have something like account determination IDs of X to use dunning procedure, account determination IDs of Y to use collection strategy?
2. If the answer to 1. is no, can one company code use dunning procedure and another company code use collection strategy?
3. What is SAP's (or any other proven) recommended approach to migrate a production system utilising dunning by dunning procedure to dunning by collection strategy?
Cheers.

Have a look
SAP-ISU will be used to carry out initial collection activities. Initial 1 or 2 reminder letters (based on the customer type, Live or Closed) will generated from SAP-ISU. Thereafter, the account will be managed in Tallyman. Thus, all the subsequent activities, such as sending further reminder letters, sending debt to collection agencies, carry out warrant activities and taking customers to court will be carried out in Tallyman system. During the time, the account is in Tallyman, no dunning activities will be carried out in SAP.
There will be daily interfaces from SAP-ISU to Tallyman to update Tallyman of Accounts that have passed a certain dunning level in SAP-ISU and any changes to the account that are currently being managed in Tallyman. Similarly there will be interfaces from Tallyman to SAP to update SAP of Accounts, that have been marked for write off in Tallyman. Fees and Charges that have been applied in Tallyman, for example court fees, warrant fees etc.

Suggestion on pocket drive and migration of iTunes to Pocket Drive

My computer is quickly getting filled up with all my music. I orginally used the default settings and had iTunes put all my music in My Documents-->My Music.
Since I am running out of space on this computer, I am thinking of getting a pocket drive and migrating my music there.
I have 2 questions:
1. Does anyone have any suggestions for pocket drives? I want one that will work/interface with iTunes well. I am looking at either:
1. Seagate - 160GB USB 2.0 Hard Drive with Pushbutton Backup - ST3160026A-RK
2. Seagate - Seagate USB 2.0 Pocket Hard Drives 5GB -ST650211U-RK
3. Iomega Silver Series 250GB USB 2.0 Hard Drive - 33215
4. Fantom Titanium 300GB USB 2.0 External Hard Drive -TFDU300
5. BUSlink 60GB 2.5" USB Hard Drive - DL-60-U2
Any suggestions/reviews for how any of these work with iTunes?
2nd question: How do I migrate my iTunes to this hard drive once I get it without messing up my iPod? Is there a suggested process for how to do this so I do not create problems for myself down the road?
Thanks,
Anne Sinha

Anybody? Higher level iTunes experts?
Sorry for the lenght of the post :-) Just trying to be as clear as possible.
The question is actually simple.
How do I transfer the 10.7 MBP library to the second internal HDD of the Mac Mini, so that iTunes will work on this MM, without losing filepaths, ratings and playlists? And without having to copy it to the boot SSD disk first which will be too small to hold the library.

Musings: MVC Front Controller/Command and Controller Strategy

Hi,
I am currently taking my first shot at implementing the Front Controller pattern, the Command and Controller Strategy flavor, in Java. When applying the pattern, my chosen point of focus is achieving as much isolation as possible of Client-specific implementation details from the rest of the framework (Web-based framework Clients, Swing-based framework Clients, queueing-based framework Clients, etc.) However, I am running into a lot of (apparent?) inconsistencies when it comes to CCS discussions "out there", so I have a feeling that perhaps I have misunderstood the Front Controller/Command and Controller Strategy pattern. Maybe the MVC gurus out there would have some thoughts on the matter.
My issues:
1.) Some CCS discussions seem to assign View presentation (sometimes called "dispatch", or "rendering", or "forwarding"?) to an ApplicationController. It seems puzzling to me, since only a concrete FrontController should include any knowledge of a concrete View structure. Shouldn't only a FrontController perform a logical-to-physical resource mapping, thus encapsulating knowledge whether a particular View is a separate, stand-alone Web page or a compound, argument-driven Swing object, and how to "present it" (by either redirecting to a Web page, or bringing a particular Swing object into the foreground)?
2.) Some CCS discussions seem to introduce Client-specific implementation details at the ApplicationController level, for example "HTTP requests" or "HTTP responses". It seems puzzling to me, since I feel that every part of the framework, except for a concrete FrontController, should be completely independent of the nature of a Client making a request. Instead, I created a generic Request object w/arguments and have a concrete FrontController translate any client-specific details into such a generic Request, before delegating to an ApplicationController.
3.) In the light of the (2.) above, I am not sure what constitutes a "response" from an ApplicationController back to a FrontController. It seems to me that the only universal "response" is a LogicalViewEnumeration: what View to present once a command has been completed, in many cases a "don't care", or a "show the requestor", or a "show a home page" (not every request has to result in changing a View). Well, perhaps a LogicalViewEnumeration as well as possible View arguments (?).
4.) In the light of the (3.) above, I suspect that any failures in Request delegation, or Command execution, should be perhaps propagated back to a FrontController by exceptions only, since, say, a WebFrontController might want to show a click-through error page, when a SwingFrontController might prefer to show an error dialog box, a LogicalErrorViewEnumeration might not make sense at all in the context of a particular Client, for example a queueing Client.
5.) In the light of the (4.) above, there is the question of an appropriate Request interface (into an ApplicationController), an appropriate Response interface (back into a FrontController), as well as an appropriate ViewArguments interface (into a FrontController and later into a View). The problem with generic Requests is that they can be created with nonsensical argument combinations, so shouldn't Requests be abstract and force proper arguments in concrete subclasses, through explicit constructors (in a sense, degenerate Commands)? The problem with Responses and ViewArguments is that... well, I have not found any formal discussion anywhere as to what those should look like. In most samples I have encountered, Responses include Client-specific implementation details, as mentioned in (2.), above.
6.) Some CCS discussions seem to introduce a Flow Manager at the ApplicationController level. It seems puzzling to me, since the whole point of the Command and Controller Strategy flavor seems to be centralization of business logic execution within self-contained Command objects. Shouldn't Requests get associated with Handlers (objects capable of actually carrying out Requests) and transformed into Commands inside an ApplicationController, thus Commands themselves return appropriate LogicalViewEnumeration back to an ApplicationController, back to a FrontController? Let's consider a ShowMyShippingAddress request coming into the framework: unless such a Request is eventually treated as a Command returning a particular LogicalViewEnumeration, it is suddenly a Flow Manager "acting" as a business logic driver. I guess the question here is: except for a few special cases handled by a particular ApplicationController (authentication, error conditions, default behavior, etc.), should flow management be considered stand-alone, or always delegated to Commands?
7.) Some CCS discussions seem to include an extra Request argument that specifies an ApplicationController to use (Request.Action="create", Request.Controller="account", Request.Username="me-me-me"), instead of using a Router inside of a FrontController to resolve to a particular ApplicationController through a generic action (Request.Action="createAccount", Request.Username="me-me-me"). I am not sure about the reason for such a design decision: why should a Client or a FrontController be allowed to concern itself with an implementation-level structure of the framework? Wouldn't any framework state -dependent ApplicationController resolution issues be best handled inside a Router, used by a FrontController to resolve [obtain] an appropriate ApplicationController, thus preventing Clients from ever forcing the framework into a possibly inconsistent behavior?
Any comments appreciated...
Thanks,
Gary

The former is (normally) intimately tied to the actual view being used (HTTP, Swing, etc.) whereas the ApplicationController typically is not. Both are involved in dispatch and event processing. The former normally renders a view whereas the latter does not.

However, you can become generic to the point where your Request and Response interfaces are only acting as "marker" interfaces (think of java.io.Serializable). Writing a truly generic controller is possible, but personally, I have never found the effort justified.

Well, perhaps a LogicalViewEnumeration as well as possible View arguments (?).A given service (if you ascribe to SOA) should be the fundamental unit in your architectural design. A good application controller would be responsible for determining how to dispatch a given Command. Whether a Command pattern is used or whether service methods are invoked directly from your FrontController, the ApplicationController should enforce common service aspects. These include authentication, authorization, auditing, orchestration, validation, logging, error handling, just to name a few.
The ApplicationController should ideally offload these aspects from a given service. The service would indicate how the aspects are to be applied (e.g., strong authentication required, x role required, fetching of existing process state, etc.) This allows services to be developed more quickly and to have these critical aforementioned aspects developed and tested centrally.
Your FrontController, in contrast, is responsible for transforming whatever input it is designed to receive (HTTP form data posts, XML-RPC, etc.) and ensure that it honors the contract(s) that the ApplicationController establishes. There are no cut-and-dry decisions though about when a given piece of functionality should be ApplicationController or FrontController. Take error handling. Should I emit just a generic ServiceException or allow the FrontController to decide what to do with a more concrete checked exception? (The FrontController, in any case, should present the error to the user in a manner dictated by the protocol it serves).

Yes. However, the ApplicationController could easily 'hide' details about the failure. For example, any number of exceptions being mapped to a generic DataAccessException or even more abstractly to a ServiceFailureException. The ApplicationController could indicate whether the failure was recoverable and/or populate information necessary to speed up production support (e.g., mapping exceptions to error codes and/or providing a primary key in an error audit log table for support to reference). A given FrontController would present that information to the user in the method that makes sense (e.g., error dialog for Swing, error page for HTML, etc.)

In most samples I have encountered, Responses include Client-specific implementation details, as mentioned in (2.), above.See comment on marker interfaces above. Nothing, however, stops you from requiring a certain sub-type in a given service method. You can still pass in the interface and validate the proper type by an assert statement (after all, in the vast majority of situations, the proper service method should get the proper instance of a given Request object). IMO, the FrontController would create the Command instance which would be passed to the ApplicationController which would dispatch and invoke the proper service method. A model response would be received by the FrontController which would then render the appropriate view.

For example, orchestration (or BPM) is properly at either the service or ApplicationController layers. However, determining which view to display is properly at the FrontController layer. The ApplicationController should receive a Command (with a populate Request) and return that Command (with a populated Response). Both the Request and Response are fundamentally model classes (within MVC). The FrontController is responsible for populating the Request and/or Command and rendering the Response and/or Command. Generic error handling is usually centralized for both controllers.

However, it seems to be the method by which commands are dispatched. They are in effect allowing a FrontController to dictate which of n ApplicationControllers should receive the request. If we allow a FrontController to directly invoke a service method, then the ApplicationController is simply a centralized framework that should always be invoked for each service method (enforced via AOP or some other mechanism). If there is a single, concrete ApplicationController which handles dispatch, then all FrontControllers communicate directly with that instance. It is really just a design decision (probably based on your comfort level with concepts like AOP that allow the ApplicationController to exist solely behind the scenes).
I might have totally missed your questions, but those are my thoughts on a Monday. Best of luck.

Data backup and migration to identical Mac

Hi everyone,
I've had my new Macbook Pro for a couple of weeks, but because the lid doesn't close properly I have to send it back to the Apple Store for a replacement now. Apple obviously cannot take care of the data migration so I have to do it myself.
What migration strategy would you suggest and what software would you use? Is there a simple way to clone my HD? The new MBP will be the same spec as the old. Unfortunately, I think I won't have the two MBPs available at the same time, so directly transferring from old to new is not an option. I have several Linux/Windows PCs and file servers (SMB) available at work, which could serve as "storage media". I might also be able to borrow a Firewire drive from a colleague.
many thanks
Hendrik

If you simply want to archive data, you can use any drive, partitioned or not. But if you want a "full system" backup, your "best bet" would be a bootable clone. You can use "Carbon Copy Cloner" which is "donation ware" so that would not cost you any money but that still leaves you with the problem of needing a free partition somewhere. So my question would be how much data is on your friend's FW drive? Could you copy that data to optical media, use the FW drive to clone your drive, and afterwards, erase the drive and copy the data from the optical disks back on to it?. That might be a "cumbersome" way to go but it would only set you back the price of a few optical disks....

WM Bulk Putaway and Picking Strategy Query for a Scenario

I have two Questions ( Putaway and Picking Strategy for Break-Bulk Handling) :
Question 1) Break-Bulk Putaway Strategy
In WM Putaway Strategy for Break-Bulk, I would like to Propose the Bin for Production Receipts based on following constraints relevant for OBD Process
Scenario:
SO-1 Production Order -1 Product -1 Ship-To Party -1 Destination -1 Loading Date 20 Days from Now 8 Levels High Product Stacking Qty 500 MT Occupies 10 Bins total
SO-2 Production order-2   Product -2 Ship-To Party -1 Destination -1 Loading Date 20 Days from Now 6 Levels High Product Stacking   Qty 1000 MT occupies 20 Bins total
SO-3 Production Order -3 Product -1 Ship-To Party -2 Destination 2 Loading Date 20 Days from Now    8 Levels High Product Stacking Qty 200 MT occupies 4 Bins Total
So-4 Production Order -4 Product -3 Ship-To-Party -3 Destination -1 Loading Date 30 Days from Now Qty 10 Levels High Product Stacking 1000 MT Occupies 20 Bins Total
S0-5 Production Order -5 Product -2 Destination -2 Ship-To Party-2   Loading Date 30 Days from Now Qty 6 Levels High Product Stacking 500 MT occupies 10 Bins Total
SO-6 Production Order - 6 Product- 1 Destination-3 Loading Date 10 Days from Now 8 Levels High Product Stacking Qty 2000 MT occupies 20 Bins Total
The production receipts will come randomly into Bulk Area any sequence any day any time 24 X 7 basis . The constraints we need to use are:
1) Materials should not be mixed
2) Different Loading Dates of Same Product also should not be mixed
3) Different destination of Same product or different products should not be mixed
4) Different Ship to Party for same destination should not be mixed
4) We need to reserve in advance maximum number of Bins that entire Sales Order occupies tentatively as soon as the First time material comes to Warehouse for the entire sales Order. Example SO Qty 500 MT assuming 50 MT occupies with different stack heights in one bin. I need to reserve 10 bins total closer to each other in bulk-area . When 2 Products comes, WM System should propose bins already reserved bin in the break-Bulk Area.
5) Different SO-2 product when arrives warehouse, it should not occupy already alloted bin for SO-1
Question 2) Picking Strategy
1) Pick List needs to be generated based on Loading Date at Load Port for all SO's and the sequence of Loading will be first last Destination in the route ( i.e. based on which is delivered at last port needs to be loaded first in the vessel at Load Port )
If the route contains 3 stages
Stage -1 --- First Discharge port
Stage -2 -
Second Discharge Port
Stage -3 --- Last Discharge Port
We need to load in Ship, the SO Product which will be discharge last i.e. Stage 3 Destination.
Next we need to Load Second destination and next we need to Load SO Product going to First Discharge Port.
This Picking proposal needs to come from WM System
How can we address this requirement in WM System?
Thanks and Regards,
Nagaraj

Hi,
Thank you for your attention to our question.
We have a workaround for this problem. I have created a Special Movement Indicator with a corresponding WM Movement Type and attached these in the LE-WM Interface to Inventory Management. We will now update our Material Masters with the Special Movement Indicator and keep the Placement and Removal Storage Types the same (the Fixed Bin Storage Type). We have tested this approach and are satified that it meets our needs.
Thanks and Regards,
Mike

Migration Strategy- AIA

I have tried to find out documents related to migration strategy(if any) defined by Oracle but could not find any. Can anyone point to any document/link so that I can know what values are to be populated in Oracle AIA for successful migration of Siebel CRM & Oracle BRM data?

Small databases could be migrated using conventional export/import for 9i and Data Pump for 10g. For larger databases I would consider transportable tablespaces.
I don't think that the migration strategy really depends on the fact that the target will use RAC One Node.
Much more important in my opionion are:
1. how much downtime you area ready to accept
2. what is the size of the databases
3. physical location of old and new server (in the same data center or in different data centers)

The difference between IEEE802.1Q Native VLAN sub-interface and Physical interface?

Hello
I think the following topologies are supported for Cisco Routers
And the Physical interface also can be using as Native VLAN interface right?
Topology 1.
R1 Gi0.1 ------ IEEE802.1Q Tunneling L2SW ------ Gi0 R2
R1 - configuration
interface GigabitEthernet0.1
encapsulation dot1Q 1 native
ip address 10.0.0.1 255.255.255.0
Topology 2.
R1 Gi0 ------ IEEE802.1Q Tunneling L2SW ------ Gi0 R2
interface GigabitEthernet0
ip address 10.0.0.1 255.255.255.0
And is it ok to use the physical interface and sub-interface with dynamic routing such as EIGRP or OSPF etc?
R1 Gi 0 ---- Point to Multipoint EIGRP or OSPF ---- Gi0 R2 / R3
Gi 0.20--- Point to Point EIGRP or OSPF --- Gi0.10 R4 (same VLAN-ID)
R1 - configuration
interface GigabitEthernet0
ip address 10.0.0.1 255.255.255.0
interface GigabitEthernet8.20
encapsulation dot1Q 20
ip address 20.0.0.1 255.255.255.0
Any information is very appreciated. but if there is any CCO document please let me know.
Thank you very much and regards,
Masanobu Hiyoshi

Hello,
The diagram is helpful.
If I am getting you correctly, you have three routers interconnected by a switch, and you want them to operate in a hub-and-spoke fashion even though the switch is capable of allowing direct communication between any of these routers.
Your first scenario is concerned with all three routers being in the same VLAN, and by using neighbor commands, you force these routers to establish targeted EIGRP adjacencies R1-R2 and R1-R3, with R1 being the hub.
Your second scenario is concerned with creating one VLAN per spoke, having subinterfaces for each spoke VLAN created on R1 as the router, and putting each spoke just in its own VLAN.
Your scenarios are not really concerned with the concept of native VLAN or the way it is configured, to be honest. Whether you use a native VLAN in either of your scenarios, or whether you configure the native VLAN on a subinterface or on the physical interface makes no difference. There is simply no difference to using or not using a native VLAN in any of your scenarios, and there is no difference to the native VLAN configuration being placed on a physical interface or a subinterface. It's as plain as that. Both your scenarios will work.
My personal opinion, though, is that forcing routers on a broadcast multi-access segment such as Ethernet to operate in a hub-and-spoke fashion is somewhat artificial. Why would you want to do this? Both scenarios have drawbacks: in the first scenario, you need to add a neighbor statement for each spoke to the hub, limiting the scalability. In the second scenario, you waste VLANs and IP subnets if there are many spokes. The primary question is, though: why would you want an Ethernet segment to operate as a hub-and-spoke network? Sure, these things are done but they are motivated by specific needs so I would like to know if you have any.
Even if you needed your network to operate in a hub-and-spoke mode, there are more efficient means of achieving that: Cisco switches support so-called protected ports that are prevented from talking to each other. By configuring the switch ports to spokes as protected, you will prevent the spokes from seeing each other. You would not need, then, to configure static neighbors in EIGRP, or to waste VLANs for individual spokes. What you would need to do would be deactivating the split horizon on R1's interface, and using the ip next-hop-self eigrp command on R1 to tweak the next hop information to point to R1 so that the spokes do not attempt to route packets to each other directly but rather route them over R1.
I do not believe I have seen any special CCO documents regarding the use of physical interfaces or subinterfaces for native VLAN or for your scenarios.
Best regards,
Peter

What is the diffrence between My Runnable Interface and Java Runnable

Hi folks
all we know that interfaces in java just a decleration for methods and variables.
so my Question is why when i create an interface its name is "Runnable" and i declared a method called "run" inside it.then when i implements this interface with any class don't do the thread operation but when i implement the java.lang.Runnable the thread is going fine.
so what is the diffrence between My Runnable Interface and Java Runnable?
thnx

Hi folks
all we know that interfaces in java just a decleration
for methods and variables.
so my Question is why when i create an interface its
name is "Runnable" and i declared a method called

with any class don't do the thread operation but when
i implement the java.lang.Runnable the thread is going
fine.
so what is the diffrence between My Runnable Interface
and Java Runnable?
thnxClasses and interfaces are not identified by just their "name", like Runnable. The actual "name" the compiler uses is java.lang.Runnable. So even if you duplicate the Runnable interface in your own package, it's not the same as far as the compiler is concerned, because it's in a different package.
Try importing both java.util.* and java.awt.* (which both have a class or interface named List), and then try to compile List myList = new ArrayList();

Difference between upgrdae and migration about oracle database

Difference between upgrdae and migration about oracle database
please give the comments

Well, the question is almost philosophic... 
In 9i, there is a Migration Guide whereas in 10g there is a Upgrade Guide. 
Furthermore, in 9i, there is the command line startup migrate whereas in 10g that's startup upgrade.
Somebody think upgrade when go to new release, and migration when go to new version. 
Others think upgrade when new version replace database in place, and migration when new version include a move of database. 
Another point of view is : upgrade is for technical, and migration for application/data. 
 
Well, after these explanations, your upgrade/migratation notion will not be more clear, but I think that is not very important, only a terminology game. The most important is to know what you need : new version or new release.

How can I access files that I moved from an older MacBook Pro to a newer one via Firewire and Migration assistant. The files show up on the new MacBook but cannot be opened. Thanks!

Get info then check permissions then add your curent user name (it was probably different on old Mac) and give your username full read/write permissions.
