Relationship between DE/WM with Applications

Hello guys,
I am wondering if there is any comment on the relationship between your DE/WM and the applications installed in there. Let me explain my case.
I want a light and fluid system where I can use my apps without worries and using only the necessary amount of resources from my machine. I end up choosing the i3WM, however I noticed that the Libreoffice suite usually freezes when I am using, such thing was really uncommon when I had my XFCE.
This is possible to be happening due to the WM only?
I think my concern is more about the curiosity of figuring this out, than any reportable bug because it is not consistently happening.
Cheers,
Bartuka!

There are a few standards defining the interactions between WMs and client programs/windows. Most important would be Xorg's ICCM. This has been build upon byt the freedesktop's EWMH. EWMH is and always was supposed to be a suppliment on top of the ICCM. But, apparently, the most recent version of a popular toolkit has decided to ditch compatibility with the ICCM and only work through EWMH messaging systems.
This is fine for that toolkit when the people who make that toolkit also make a very widely used and influential WM/DE/Borg-Collective. All of their tools work together quite well, but if you use some of their tools, you may need to commit to using only their tools as they have decided to break ties with the rest of the X11 world (arguably this might not be an issue for long if Wayland gains as much traction as some seem to suspect it will).
XFCE has bowed to the pressures from that one version of that one toolkit. i3wm has not done so and instead remains compliant with existing standards. So the problem is not with your WM, but with the toolkit used by recent versions of libreoffice. Don't complain to the LO people, though - unless it's a suggestion that they use a different toolkit. Complain to the GTK3 people ... if you want, they probably wont listen as you are not using GNOME.

CRM - Bapi for creating relationship between BPs with sales area data

Hi
I am looking for BAPI for creating relationship between business partners with sales area data in CRM 5.0.
Example - I would like to create relationship type CRMH03.
Bapi BUPR_RELATIONSHIP_CREATE does not allow for maintaining sales area data (Sales org, distribution channel, division).
Does anybody know such a bapi?
Regards
Radek

Hey Radek,
I am actually looking for the same functionality. Were you able to find a solution although no one replied to your question in this thread? If so, it would be very helpful for me to know. Maybe you have to combine more BAPIs in order to add the organization information to the relationship. But I have no idea how.

Relationship between condition type and payment term

Hi,
I created a purchase order (only 1 item) with with payment term "Within 14 days 2 % cash discount" So a condition type SKTO auto added for the item with discount is 2%.
can anybody show me the relationship between payment term with the condition type and the IMG T.code to make this relationship?
Thanks
Long

If you go to IMG - MM- Purchasing - conditions- Define price determination process - Define Condition types
For SKTO the condition category is E- Cash discount
For this condition type which is defined in the calculation procedure , the system internally derives a percentage from the terms of payment and inserts it in the condition type with the category E

What's the relationship between Agent and JMX-instrumented applications?

Hi, I'm a beginner of EM and JMX. I'm trying to integrate my application with EM. After reading some documents, I find I need to make my application JMX-instrumented first and then design the plug-in. But I'm still a little confused about the relationship between the Agent and the JMX-instrumented appliactions.
Here is what I'm confused:
1. Should the EM Agent be installed in the host where my JMX-instrumented application is installed? If this is true, then that will mean Agent cannot monitor the remote resource. But it sounds not reasonable.
2. When making the application JMX-instrumented, we should use the platform MBeanServer or create our own MBeanServer? Do they have a major difference? and will it impact the plug-in design?
Thanks in advance.

Answers to your queries:
1. Should the EM Agent be installed in the host where my JMX-instrumented application is installed? If this is true, then that will mean Agent cannot monitor the remote resource. But it sounds not reasonable.
Its not necessary that EM Agent should be installed on the same host where JMX-instrumented application is/are installed. EM Agent has a fetchlet (named OJMX) that can be used. Refer to [Management Using Web Services and JMX|http://download.oracle.com/docs/cd/B19306_01/em.102/b16246/web_jmx.htm] for more details on emjmxcli tool, which can help to build the plug-in which can monitor the MBeans. [EM Extensibility Guide|http://download.oracle.com/docs/cd/B19306_01/em.102/b16246/toc.htm] contains all the details for building a plug-in.
2. When making the application JMX-instrumented, we should use the platform MBeanServer or create our own MBeanServer? Do they have a major difference? and will it impact the plug-in design?
To best of my knowledge, plug-in design doesn't get impacted

Problem with 1:many relationship between entity beans.

Hi All!
I have two tables TMP_GROUP and TMP_EMPLOYEE with following fields:
TMP_GROUP: ID, CAPTION, COMMENT, STATUS.
TMP_EMPLOYEE: ID, LOGIN, GROUP_ID.
For this tables i create two entity beans GROUP and EMPLOYEE respectively.
The relationship looks like this
descriptor ejb.xml:

            </ejb-relationship-role>
        </ejb-relation>
descriptor persistent.xml:

               <table-relationship-role

                    <cmr-field>employees</cmr-field>
               </table-relationship-role>
               <table-relationship-role
                    key-type="NoKey">
                    <ejb-name>EmployeeBean</ejb-name>
                    <fk-column>
                         <column-name>GROUP_ID</column-name>
                         <pk-field-name>ejb_pk</pk-field-name>
                    </fk-column>
               </table-relationship-role>
          </table-relation>
Now i implement business method:
public Long addEmployee(String login, long groupId) {
          Long result;
          try {
               EmployeeLocal employee = employeeHome.create(login);
               GroupLocal group =
                    groupHome.findByPrimaryKey(new Long(groupId));
               Collection employees = group.getEmployees();
               employees.add(employee);
               result = (Long) employee.getPrimaryKey();
          } catch (CreateException ex) {
               result = new Long(0);
          } catch (FinderException ex) {
               result = new Long(0);
          return result;
When i call this method from web service, the following exception is raised:
com.sap.engine.services.ejb.exceptions.BaseTransactionRolledbackLocalException: Exception in method com.mypackage.GroupLocalHomeImpl0.findByPrimaryKey(java.lang.Object).
P.S.
1) I have transaction attribute set to "Required" for all methods of all beans
2) I have unique index for each table:
TMP_GROUP_I1: CAPTION
TMP_EMPLOYEE_I1: LOGIN (however i think GROUP_ID must be added here too)
3) I tried many:many relationship with this tables and it works fine
4) I try another implementation of addEmployee method with
EmployeeLocal employee = employeeHome.create(login, groupId);
without using GroupLocal cmr-field and GroupLocalHome findByPrimaryKey method, the result is same error.
Can somebody help me with this problem?
Thanks in advance.

Relationship between NetWeaver PI and Composite Application Framework

I am new to PI and CAF and don't understand the relationship between these technologies. They both seem to allow users to identify and integrate application services.
Are they complementary? Is PI required for using CAF, or only in some instances? Is PI only needed if the application services are coming from both SAP and Non-SAP environments?
It would be appreciated if someone could shed some light on this for a generally non-technical person. I keep reading the PI and CAF product literature and can't clearly see the relationship.
thank you.

Problem with a 1:M relationship between two entity beans

I am having trouble trying to implement a 1:M relationship between two EJB2.0 entity beans using and EJBQL query. I have an ApplicantEJB, which contains a collection of phone numbers. The applicant table in the database has one primary key, applicant_id. The applicant_phones database table has a compound primary key--applicant_id and phone_type_id--so I have implemented a custom PK class to represent this, PhonePK. I have implemented a findByNameAndPhone method in my ejb-jar.xml file with the following syntax:
SELECT object(a) FROM applicants a, applicant_phones p where a.applicantID = p.applicantID and a.name = ?1 and p.phoneNumber = ?2
If I deploy this, Orion/OC4J translates the query in the orion-ejb-jar.xml with an incorrect reference to the applicant_phones.applicant_id column:
SELECT a.applicant_id FROM applicants a , applicant_phones p WHERE ((a.applicant_id = p.applicantID ) AND (a.name = ?) AND (p.phone_number = ? ))
I must have something wrong with the ApplicantEJB and PhoneEJB primary key mappings in my orion-ejb-jar.xml file, but I have tried many different combinations of values and keep getting them overwritten by the container with each deployment. Why is Orion/OC4J defaulting the applicant_id reference to the ob[i]Long postings are being truncated to ~1 kB at this time.

1-to-1 Relationship Between UI and subVI Data Cluster

Discussion continued from here.
In summary:
JackDunaway wrote:
Yes,
I can see clear benefits in implementing this Idea - that is, if your
underlying datatype elements have a 1:1 relationship with the UI
elements.
I will
illustrate this point by showing some potential flaws in your example:
"Profile Running" and "Profile Complete" are mutually exclusive, no?
Wouldn't it be better to have a single enum named "Profile" with three
elements "Idle, Running, and Complete" for the underlying datatype?
Having two mutually exclusive pieces of data in an underlying datatype
is among my favorite of code smell indicators.
Also, the underlying datatype probably only needs "Forward Miles" and
"Reverse Miles" since "Total Miles" is derived. Exclude "Total Miles"
from the underlying cluster and just show the sum for display.
Another
argument against using a 1:1 relationship: the customer now wants to
multiply speed by -1 if Direction==Reverse and not show the Direction
enum on the UI. The data source (the VI that generates the data) would
need to be updated using your 1:1 relationship. Using underlying data
different from the display data, only the data client (the UI front
panel) needs to change. I would be much more inclined to service the UI
FP for a cosmetic upgrade rather than tracing the data source back
through the HMI framework, through TCP, back to the RT, back to FPGA...
Basically...
I question a perfectly overlapped Venn Diagram where the set of data
shown to the user equals the dataset used for underlying data
processing/messaging/storing. The underlying datatype should be as
stripped and streamlined as possible, while the display datatype can
inherit all the flair and post-processing that Upper Management wants to
see in a UI.

Yes, I can see clear benefits in implementing this Idea - that is, if your underlying datatype elements have a 1:1 relationship with the UI elements.

My long delayed response:
The indicators you see map to tags on the PLC. That is, we were connecting through OPC to an application on a PLC that was written ~15 years ago. I have a VI where I read a bunch of SVs (Shared Variables). Each SV is bound through OPC to a PLC tag. In the interest of disclosure, two 16-bit tags are required to represent each 32-bit mileage number. In the same subVI, I read each set of mileage tags, convert, and feed my subVI cluster indicator. The same is true for wheel size: three bits get converted to the enum. Regardless, though, I have one subVI that reads SVs and outputs the same "underlying data" cluster that is seen on the UI. The UI has a "Faults" cluster full of fault Booleans that follows the same logic. When the user configures a profile of steps, they do so via an array of "step" clusters (although the cluster look is hidden for aesthetics). It's the same thing as above except we write tags instead of reading them.
In my case, each set of 16-bit tags is worthless as two 16-bit numbers. They are only useful as a 32-bit mileage, so I don't pass around the raw 16-bit data. The same is true for the wheel size bits. My software can just as easily (in fact, more easily) operate on the enum. So, the underlying cluster from the subVI is programmatically useful and applicable to the UI. I would guess that the same is true for a lot of RT applications, where the read VI can have some intelligence to process the data into useful / applicable clusters.
There are going to be cases where "Upper Management" would like to see "flair and post-processing" as you say. Your speed illustration is a good example of this. There are also instances where the cluster works fine on the UI the way it is (like this one and many others that we've seen).

"Profile Running" and "Profile Complete" are mutually exclusive, no?
Wouldn't it be better to have a single enum named "Profile" with three
elements "Idle, Running, and Complete" for the underlying datatype?
<LabBEAN response
Did you mean "not" mutually exclusive? We combined 3 "dependent" (not mutually exclusive) Booleans into an enum for Wheel Size, as I mentioned above. Not sure now why we went the other way with these two (this was 2 years ago). In any event, with regard to UI representation, I still pass a cluster out of my read-raw-data-and-process-into-cluster subVI up to the applicable queued state machines and to the UI.

Having two mutually exclusive pieces of data in an underlying datatype
is among my favorite of code smell indicators.
<LabBEAN response
Working with applications written in ladder logic, it is not uncommon to see separate Booleans that indicate the same condition. This seems to be especially true when safety is a concern. That is, ladder Coil A ON and Coil B OFF == switch open. Coil A OFF and Coil B ON == switch closed. If you ever read OPC tags from Coil A and Coil B and the two are the same, you know the ladder is in transition (hasn't updated the tags). Throw that point out and read again.
I, too, appreciate our back-and-forths. Good discussion.

Separate Views from Implementation for Strict Type Defs

Thanks for replying, Jason. Let me see if I can craft a coherent response after getting back up to speed...
(...later)
OK, let's go. I'm going to fully agree with you that LabVIEW imposes a strange constraint unique from most other languages where a Typedef defines two things: the underlying data structure, and also the view. A Strict Typedef should be more accurately deemed the Datatype-View-Definition, and a Typedef would be more accurately called the Datatype-Definition-and-View-Suggestion. And to be clear, there are two types of views: the programmer's view (a SubVI look and feel) and the UI view (what the user and Upper Management sees). (Finally, I admit I'm ignorant whether view or View is more a more appropriate term)
Linking the programmer's view to the datatype is perfectly fine with me, and based on your original Idea I think we both agree that's OK. I think we run into a disagreement where you have loosely tied the concept of "Strict TD" to "UI View".
Historically, I have used Strict Typedefs for the programmer's view (SubVIs), since I like to maintain a "functional UI" at the SubVI level. I don't use type definitions on User Interfaces - only Controls. That's the reason your Idea does not appeal to me, but perhaps if your Idea were implemented, it would appeal to me since View and Implementation would be divorced as separate entities within the Type Definition. (Does that classify as a Catch-22?) So, you're Idea is fundamentally suggesting that Type Definition .ctl files should be more accurately called "a container that holds both a Type Definition and any number of View Definitions as well".
Fundamentally, I think I finally understand the gist of your Idea: "let's ditch this weird constraint where View and Datatype are inextricably defined together in one file", and for that, I'll give Kudos to the original Idea. I got really tied up with the example you used to present the Idea, and plus I'm still learning a lot.
Additional thoughts:
This Idea reminds me of another: Tag XControl as Class View
We've still got some arguing to do on a 1:1 relationship between underlying datatype and UI presentation, so put your mean face back on:
Since our last conversation, interestingly, I have been on an anti-Typedef kick altogether. Why don't you drop some feedback on my attempt at a completely typedef-free UI framework?
