1. I aggree with you that this is a weak point of Forte. A possible workaround is
to have a Workspace 'BugFixes' where you fix your bugs without affecting the rest
of your code.
1 - When you integrate a workspace into the repository it takes all the
changes you have made in that workspace and 'saves' them to the
repository. However, what if you have a workspace which has a half
finished project as well as another project which you make a small but
important change to. The small change must go back because other
developers need the 'fix', but the half finished project will essentially be
'broken' if it is integrated at this stage. Is there any way to integrate
only specific projects? If not, how do you stop the half finished project
being copied into the other developers' workspaces when they do an
'Update'.
Hi Forte'rs
I just would like to express my deep appreciation for the way integrating
workspaces works in Forte.
This makes it a lot safer to work with, because you can only test the
COMPLETE set of code and not just the 'few' changes you just made...
I, at least, always make quite a few changes in a bunch of classes, so it would be
a complete mess to try to sort out which changes to integrate and which to keep
in my workspace only.
Now I also have been frustrated not being able to make a quick (and dirty) fix - but
in hindsight - it is clear that you cannot be sure that the fix works in the real world
(you know: the stuff outside your own heavily modified workspace).
So while I agree with everyone that got frustrated by not been able to integrate
just a few changes, I am also happy that this is not allowed!
may the forte be with you all

Workspace integration and Database Mapping

Hi there folks,
I have a couple of questions about Forte.
1 - When you integrate a workspace into the repository it takes all the
changes you have made in that workspace and 'saves' them to the
repository. However, what if you have a workspace which has a half
finished project as well as another project which you make a small but

'broken' if it is integrated at this stage. Is there any way to integrate
only specific projects? If not, how do you stop the half finished project
being copied into the other developers' workspaces when they do an
'Update'.
2 - We have designed a class called 'Criteria' which contains several
attributes, each of which are a class called 'Criterion'. The Criterion
class contains the attributes "Active", "From" and "To" which are simple
data types. Now if the 'Criteria' class is used for attributes in two other
classes (Say "ClassA" and "ClassB"), how can you match these
classes to RDBMS tables? I realise you could explicitly name columns
and attributes in SQL Select, Insert and Update statements, but that
has now defeated the purpose of creating the 'Criteria' class in the first
place. Namely, ease of future maintenance. Am I missing something
here?
Thanks in advance for any help.

Duncan,
1. There is no way to integrate a part of your workspace/class and not the other. So, before you integrate you have to make sure that it compiles and also your changes do not break what others are doing when they update. The only way to do it is to export the half finished projects/classes, integrate the good workspace and then import it back and continue your work.
It is important that there is some discipline and lot of unit testing as your application grows bigger and code larger and you go towards deployment. This will reduce the possibility of breaking others code (after you integrate and others update).
2. From what I have seen, compared to lot of tools Forte goes very far in providing a good and easy mapping from objects (rather object attributes) to table column mapping. All said and done there is a mismatch between pure objects and an RDBMS table. We have to live with it until we get to a stage where we can have OODBMSes which are still in its infancy compared RDBMSes. In forte you can map attributes of an object whose names are same as the column names. Another option is to alias the column names to match the attribute names in the SQL.
Now for my pet discussion of mapping objects to tables - It is easier and simple if you map an object to a table. OO purists might argue with me and say that is not very OOriented. That is right but we are dealing with a mismatch here. It is just that we are impedance matching by trying to persist an object into an RDBMS table.The other possibilities are to map 1 to many from object to a table and vice versa. Choose whatever is right for you. Eventually keep the performance in mind when you choose an approach.
Hope this helps.

Active Directory Integration and Drive mapping

We currently have a lab with 20 Mac Pro machines, and an Xserve.. all running 10.5+. We are looking at integrating the existing users, through AD, into the Xserve. We have been able to do simple authentication and drive mapping to the windows share easily enough. However what we would like to be able to do is mount a share from the Xserve for only the Macs for the students that will be in there, while keeping the Home directory from AD intact and still being mounted.
Is that possible or I am going outside of what I am able to do?
Thank you

If I understand what you are asking, then you will need to bind the Xserve to AD, then promote it to an OD master. This will allow you to manage the AD groups without schema modification to AD, basically allowing the storage of Apple MCX attributes. You can then create a group in OD and add the AD group to it. Then, manage the OD group and set login preferences to automount a share. Check the box to allow unique user credentials to be sent. Since you are in a Kerberos/Single sign on environment, you will be able to pull this off very easily.
During the workstation bind, make sure the UNC home path option is select and that you are choosing the correct protocol (SMB or AFP). That will allow the AD defined windows home folder to mount. Then follow the OD MCX stuff above to handle the mount of the share. You might also want to look into augmented records if you need to get management to the user level. I've had no need for this yet so I've not used it. Manage by nest AD group has always been enough because everyone gets the same stuff.
Hope this helps

Different user IDs in UME and ADS, mapping?

Dear All,
we want to implement Integrated Windows Authentication for Portal.
For such a implementation we we've found descirption in the SAP Note: 935644 - "Configuring Kerberos on NW04 against Database User Store"
The problem is, that we have different user IDs in J2EE Engine and MS ADS user store and the mapping has to be done "via additional UME attribute".
Anyone know how to implement such a attribute mapping?
Thanks for help!

Oracle Express(Analytical workspace?) and Oracle warehousebuilder

Can somebody please explain when and why to use
Oracle Express(Analytical workspace?) and Oracle warehousebuilder.
When should each of these tools be used?

Oracle Express is an old, de-supported product that has been replaced by Oracle Database OLAP Server http://otn.oracle.com/products/bi/olap/olap.html.
Oracle Warehouse Builder (OWB) is a data integration design and management tool. One of OWB's areas of functionality is enabling OLAP. All OWB OLAP related materials are summarized and linked from OWB Self-service Education page here http://otn.oracle.com/products/warehouse/selfserv_edu/OLAP_cube_creation.html

Numbers/Address Book and Google Maps

I would love to integrate my spreadsheet of addresses or my Address Book with Google Maps.
Is this possible? Somehow?
I take a lot of trips across the country and don't always know when I will be driving by my friends. But if I had a map I could glance at to see where they all are, I would know that I could schedule a lunch with a friend halfway or something like that.
I have heard about MapPoint, but don't know if there is anything like this that is free/affordable/non-MS.
Thanks!

Integrating in Numbers would not be automatic. You'd have to format links to assign to each address.
I've seen plug-ins to use Google maps with Address Book. Try a search on MacUpdate or VersionTracker for Address Book.
I think one of the features for Address Book in Leopard is integration with Google maps.

Application Integrator and SSO by SAPLOGONTICKET

After the docs (e.g. "How to Use the Application Integrator") and blobs mainly focus on user mapping, I wonder how to configure SAPLOGONTICKET in com.sap.portal.appintegrator.sap.Generic efficiently.
Does combining "URL template" and "URL template fraction for SSO" give a chance for sending a Login Ticket to another server (distinct domain)? Or is the "authentication" part in "URL template" useless for Login Tickets (as stated in <a href="https://www.sdn.sap.com/irj/sdn/thread?threadID=21141">Thread 21141</a>)?
Thanks
Gerhard

Hi Gerhard,
If your system is set to log on with SAP logon tickets for authentication, you can specify an authentication template in parameter SSO2Template, e.g. MYSAPSSO2=<Request.SSO2Ticket>. That's all it takes on portal side to configure the SAP Logon Ticket when using application integrator. .
If you want to use SAP Logon Ticket for multiple domains (portal server and backend server are in different domains) you have to take special care. Have a look into the <a href="http://help.sap.com/saphelp_nw2004s/helpdata/en/a0/88a340fa432b54e10000000a1550b0/frameset.htm">SAP Library</a> to find out how to configure logon tickets for multiple domains.
Hope I could help!
Best regards,
Martin

When do we go for ABAP mapping and Java mapping

Hi friends,
At present I am working on graphical mapping in XI ,can you guys give me with an example or scenario when do we use ABAP mapping , Java mapping or XSLT mapping.
Thanks in advance
Sud

<a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/sdn/forums">https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/sdn/forums</a>
I have standard XSLT mapping programs available for my scenarios, so use XSLT mapping. Similarly with Java mapping, For most scenarios, message mapping does the job too well. Abap mapping similarly is used to leverge existing ABAP base. If message mapping becomes confusing and hard to follow with too many functions, I go for Java mapping (just my way). I havent used ABAP mapping thus far.
Discussing ABAP mapping
ABAP mapping is developed in ABAP work bench. ABAP mapping needs to be transported to integration server and XI does not support this transport and have to do with ABAP transports.
Customers who can develop mapping program on SAP web AS and can transport them there can use ABAP mapping
*ABAP mapping programs cannot access the value table
*Since ABAP mappings are executed on ABAP stack SAP does not provide any ABAP mapping programs
*ABAP mapping programs must exists with one single version in IS, unlike JAva and XSLT mapping that can have multiple versions of mapping program

Fixed Values and Value Mapping

Hi Experts,
I hav a doubt regarding these to funnctions in Messege mapping. In both teh functions , we can change a value coming from Load to some thing else.
Like
A=1
B=2
C=8.
The difference i hav noted is the in case of fixed values, we can assign the valsues in the messege mapping itself, and in case of value mapping it is assigned in the value mapping table in integartion directory, and thsi can be seen through Runtime Workbench in Cache Monitering. . Apart from that there seems to be no big significat difference in the application .
Pls correct me , if I ma missing out something.
Pls tell me if both hav the same functionality, why were these 2 functions made , any 1 of them, preferably Value Mappimg Function could hav been enough.
Regards,
Arnab.

Hi
Fixed value mapping is Message mapping Specific
But Value mapping allows u to create a Schema and group .
Value mapping functionality will be well understood in large integration where many mapping programs using same conversions.
Maintain advantage is maintance is easy with value mapping because if any chnages in value , just ID change is enogh no need to go mapping but this is not with fixed value
For instance if u r using Fixed value in 50 mapping programs u need to change in all
But if u r using Value mapping just one ID
Which one u prefer
all based upon u r landscape for mapping

Message Mapping And Interface Mapping

Hi,
I have 2 software components.
One is for sender and one is for receiver.I have created all the Data types,Message type and Message Interface fro sender in the first Software component and data types ,message type ,message interface for the receiver in the second software component .
Now, in which Software component should i create Message Mapping and Interface Mapping?
Thanks in Advance,
mvk

Hi,
You could use the created Message type and Message interfaces in Sender as well as receiver software components for creating message mapping, interface mapping and integration scenario.
Generally it makes sense to maintain the message mapping, interface mapping and integration scenario in receiver software component. The message mapping and Integration scenario is specifically based on the receiver end requirments, so its preffered on receiver software component.
The sender side details could be reusable in case if you need those for another new receiver software component. If you maintain it in sender component, then that will lead to mix-up all the things on sender side even though its based on receiver end.
I think this could help you.
In PI7.1 now there is concept of Folders to maintain all the interfaces appropriatly and leads for reusability of existing objects.

Workspace Manager and APEX

I was experimenting with using workspace manager (via DBMS_WM) to version a set of tables. Does everything I want, easily and quickly.
However, when I update versioned objects in APEX, and then look at the HIST table, the user name is APEXPUBLIC_USER.
I understand why this is, but does anyone know of any means of overriding the user saved in the _HIST table, using the APEX user instead.
I had a look at the IOT on the BASE object, but didnt see where it inserts into HIST.
Any help greatly appreciated.
Thanks, Rob

Hi Robert,
some time ago I created a german how to document on Workspace Manager and APEX - you'll find it here.
http://www.oracle.com/webfolder/technetwork/de/community/apex/tipps/wm/index.html
Be careful - in the following text a "workspace" is not an APEX workspace but a DBMS_WM workspace.
The "_HIST table" is not a table but a view. When version-enabling a table Workspace Manager renames the table, adds columns
for the versioning information and creates some views. The most important view is the view which "replaces" the original table. The
"_HIST" view is another view.
Workspace manager also creates an INSTEAD OF trigger which "catches" the DML done on the view (which now has the name
of the original object). That DML is being enriched with User and timestamp information and then placed into the original table
(which now has another name).
The user information is there because Workspace manager allows to grant privileges on "workspaces" to other users. So you ...
* first version-enable a table
* create a new workspace (CHANGES_1)
* do some DML
* grant access on your workspace to the other user say: HUGO
Now you and HUGO can access the workspace CHANGES_1 and review your DML. All other users can only see the
table status before your changes. So as long as you don't access the version enabled object from different database
schemas (i.e. different parsing schemas) and you don't use the DBMS_WM.GRANT.... procedures you don't have to care
about the APEX_PUBLIC_USER information in the HIST view. You can live with the APEXPUBLIC_USER information.
Does that help ...?
Best regards
-Carsten
