[REQ] Service Objects "binding" methodology

Hi,
When we program in express, the resulting service objects offering 'business model', and the one offering database accesses
seem to be bound together.
The BMServiceSO and the BMDBSO are bound together.
Forté prevents you from moving the BMDB, telling you that it's linked to BMServiceSO.
When you move BMServiceSO or you tag it as referenced SO, it takes the BMDBSo with it.
How to do this manually with TOOL code ?
Thanks for any suggestion,

Namespace URI for a Service Object

A Distributed Object registered using task.Part.ObjectLocationMgr.RegisterObject(name = '/TestSvc',object = tm, duration = DO_DURATION_SESSION) can be retrieved using task.Part.ObjectLocationMgr.BindObject(name = '/TestSvc', classType = Object). But how can I dynamically bind to a service object registered by the Forte System ? What Namespace do I need to use in ServiceName value for this ?

Forte has a build in name service where it registers all of the service objects. (And more.) If you use something before UDS 5.0 you can see the name service in E-console under the application view. UDS 5.0 even allows you to drill down into the name service as part of Econsole.
You dynamicly bind with this code if you do a little research on bindobject:
bindName : textdata = new();
myName.replaceParameters('site/%1/%1-%2', SampleProjectName_cl0, SOSampleName);
myServer = (TUBaseService)(task.Part.ObjectLocationMgr.BindObject
(name = bindName, classType = serverClass));
This would bind to the SOSampleName service object in the project SampleProject. Notice that the compatibility level is important.
Hope this helps.

Getting bug error while compiling object binding code in javaFX

I am new to javaFX and exploring it from just last two days.
today i tried a simple binding object example and got weird exception about bug.
i created a simple file with name Calculator.fx having just one line public var result=1;and used object binding in another file Customer.fx with following code
var myStreet=21;
var address= bind Calculator{
result:myStreet;
println({address.result});i got following output error

FIM MA Export errors. There is an error executing a web service object creation.

While checking for the permission, we have figured that the Built-In Synchronization account is being deleted by an Expiration Workflow.

RE: Re[2]: Service Object events and LockMgr

I think there are a lot to implement a lock manager. If several objects
should be updated in one transaction, the lock manager should be able to
handle rollbacks. Other things like release lock when exception happens,
avoiding dead locks, etc. Most of the features are provided by DBMS, so
I think using a option 2 would be a better solution.

The second one - you just need some unique value that will identify
the object being locked. You should register with the Lock
Manager only
the objects that you want to lock.
For me, one of the goal of such pattern is to give you some freedom
from the specifics of the database lock mechanism.

Re: Service Object events and LockMgr

On the option that you have considered, I have implemented the same model
in my previous project (using Java/RMI), but I felt that it is more than
what is normally needed for concurrency protection.
I can suggest another option that is worth considering which is in place in
our app for concurrency.
Almost every table in our db has created By, created On, modifed By,
modified On columns. The parent class of all business objects has
attributes that correspond to these four columns. In addition to these
four, there is a fifth attribute (introduced when concurrency was built)
called originalModifiedOn. Upon retrieval from the db, it is set to
modifiedOn value (from the db), during UPDATE, the value in this column is
added part of the WHERE clause. So when the second user tried to do save
the same object, the underlying db update will get a 'zero rows updated'
which is translated into an application error 'possible concurrency
error'. The user re-retreives the now 'stale' object before applying their
edits.
A lot of these things are and can be built into the framework imposing very
little work that each Object needs to do to have concurrency protection.
I am not sure if there is a mention in the Patterns paper of this model,
but it is very easy to implement and supports what is needed.

Hi folks,
We're currently looking at strategies for dealing with the simultaneous
updates to the database from multiple clients (concurrency
management). That is when two (or more) clients load the same object to
edit it, then make different changes and save them to the database.
We have a copy of a Forté document (from the "Patterns" course, I
think) which describes three methods of dealing with this:
1) Lock the database table row as soon as a client select it for editing
and hold the lock until it is saved.
2) Immediately before 'saving' check that the database hasn't changed
(either by reading what's there before updating, or by using a huge
'where' clause that contains all unchanged fields)
3) The Forté "LockMgr" pattern, which uses a service object with notifier
proxies to allow locking and updating notification between the clients.
Option 3 is obviously the most robust method, but it requires a fair
amount of coding and could also be a bottleneck for database reads and
writes.
But I have another option for which I was looking for opinions. What if
we had a "Change Event manager" which broadcast an event every time
a change is made to the database. Each business class would have its
own event. If the event had the object's primary key as a parameter, then
clients editing that particular object type could check to see if the object
currently on screen is the one that changed. That way you could disable
the 'save' until they had refreshed their on-screen data.
It's not particularily elegant, but it's reasonably simple to implement. It
also deals with changes sent across our WAN from other database
servers.
But this option is only worthwhile if you can replicate the "Change Event
manager" SO and still register for an event on the client. Can clients
register for SO events and receive an event generated by any of the SO's
replicates? Or when you register for an SO's event do you register for
only one instance of the SO?
Thanks in advance for any answers.

Hi,
Just wonder exactly how this Lock Manager can be implemented. Do you mean that you are
going to cache every object that is instantiated from the database? Or you just cache
the object id, primary key, etc?
Frankly speaking, I won't attempt to due with this kind of currency coding myself as
the database vendor has spent years in coding just to do this.

I would recommend you to use the following approach (of course if you
do not have some special requirements :) ):
1. You should have a LockManager that will synchronize all clients in
their attempt to modify/delete objects in your application.
2. Each client, when attempts to modify/delete some object, it must
LOCK it using the services provided with the LockManager.
3. The requested operation can be performed only after successful
locking.
4. If a lock can not be obtained (for example if the object is already
locked by some other client) then the operation is aborted.
The details of this pattern depends on your needs. :)
Hope this helps.

I have something this (please, some patience :-) ):
//Example: handle event (the event is Beep)
interface AlarmListener{
void Beep(String hour); //declare a event handler
//The class that "raise" an event Beep
class Clock{
AlarmListener theAlarmListener; //Referecne to an listener object
//Register an listener object
public addAlarmListener(AlarmListener theAlarmListener){
this.theAlarmListener = theAlarmListener;
private ringAlarm(){
theAlarmListener.Beep("10:00 P.M."); //Raise Beep event
class Guy implements AlarmListener{
public Guy(){
Clock clock = new Clock();
clock.addAlarmListener(this);
//Handle Beep event
void Beep(String hour){
System.out.println("Ohhh, its time of wake up!!!");
//End
But, in this model my source object have only an listener object.
This can be improved by a array, like this:
class Clock{
AlarmListener[] theAlarmListener = new AlarmListener[10];
private int i = 0;
//Register an listener object
public addAlarmListener(AlarmListener theAlarmListener){
this.theAlarmListener[i++] = theAlarmListener;
//More code...
making to a side the limitation of size of an array (although this can be managed somehow if it is necessary), the problem begining to be more and more complex... i.e., it is necessary to create a method for unregister a listener...
And, what about with multi-threads programs??? The addAlarmListener method should be synchronized or something??
It should have an easier way!
PD: I think that I have used the Delegate pattern in conjunction with some other pattern.
PD: Forget my English. It is terrible

Hi Sandeep,
I am not totallt getting your point but can suggest following points:
1. Check whether these object are displaying in DIR's as object links.
2. If it is there then it shoud be displayed in document data of those objects.
3. Check that documents are properly checked-in.
Hope this may help.

Disabling delete button in service object list fom VA03

Hi all,
i want to disable the delete and change button in attachment list of service object list (GOS) IN T CODE VA03.
I have found that it can be done by modifying the method CHECK_STATUS of class CL_GOS_SRV_ATTACHMENT_LIST,
and then calling it in t code SGOS.
i have copied this class to a Z CLASS but unable to modify the method it asks for access key.
any help is highly appreciated with example.
thanks,
pankaj gupta

Hello,
The authorizations in GOS has nothing to do with the authorization in
application level, e.g. in VA03. In standard you can use the new
authorization object S_GOS_ATT from SAP note: 1293080.
Otherwise:
A possible workaround could be the following:
Without an authorization the attachments are only deletable by the
owners or by users with sapoffice administrator authorization. If you
do not give users this sapoffice admin authorization, than only the
owners are able to delete the attachments. See SAP note: 552127
(point 3).
OR due to a modification some functionalities can be restricted.
For more information you can read the SAP note: 491271.

Service objects inside libraries (WAS: Interfaces in Forte -has anyon

The following message is actually not about interfaces, but libraries:

> Date: Thursday, July 30, 1998 11:12 AM
> Subject: RE: Interfaces in Forte - has anyone used them?
>>
> Just to clarify a few things:
>>
1) Just to be 100% correct -- it is actually Libraries that areloaded and
not Interfaces. The distinction is important because a librarycould
potentially implement many interfaces (or provide manyimplementations for a
single interface).
2) The code in a Library may reference a service object, but itmay not
define a service object. Of course any SO's referenced by thelibrary
must already be known to the loading partition. It is OK to havecode like
this in a library:
MySO.doSomething();
The documentation is a little vague on this point, but I haveconfirmed that
this is true through Tech Support and by experimentation.
Actually you CAN define and use service objects inside libraries
(compiled or interpreted) with two restrictions:
1) You can not define two service objects inside library in different
projects and call one of them from another. If you need that, both
service objects must be in the same project.
2) If service object is defined and used only by library (if it never
referenced directly by application code), than in order to be able to
partition application, you will need to create dummy method inside
application, which will reference this service object (you do not need
to execute this method - just have in the code).

The way stateful Web services are currently handled is through the use of cookies ... once your stub invokes a stateful Web service a cookie is created which routes subseqent requests back to the Web service.
In your scenario, the problem is given one client has creates Web service 1 and now Web service 2 would like to be able to use that state it really isn't possible unless you engineer a solution yourself ... you would need so somehow set the cookie on your Web service 2 client to that of the original client to Web service 1. State tends to be based around an individual client versus multiple clients for that state.
There are numerous ways around this but you would be engineering around the issue ... the easiest is to write the state out somewhere so that it can be shared.
This section of the doc gives a brief overview:
http://download-west.oracle.com/docs/cd/A97688_06/generic.903/b10004/javaservices.htm
Lastly be aware there is a bug with timeouts in stateful Web services in Oracle9iAS 9.0.3 that has been fixed in 9.0.4. I can't find the thread here that documents it but when I track it down I will post the link so you can see the workaround.

I did quite an amount of debug of transaction Code FB03.
SO_OBJECT_READ is the function module that is used to read this data.
The inputs are as below:
folder_id is generated from:
Within CL_GOS_SRV_PERSONAL_NOTE and METHOD check_status -->
        CALL METHOD cl_binary_relation=>read_links_of_binrel
          EXPORTING
            is_object              = is_lporb
            ip_relation            = 'PNOT'
            ip_role                = 'GOSAPPLOBJ'
          IMPORTING
            et_roles               = lt_roles
where
is_lporb-typeid = BKPF
is_lporb-catid = BO
is_lporb-instid = 'CompanyCodeDoc nofiscal year'
lt_roles-instid+12 is used for the SO_OBJECT_READ function module
Thanks,
