Real Time Screen Updation in the Front End

I working for a banking sector, My requirement is that, there is a screen which stays open 24 hours 365 days , there are some database changes happening in the backend , the data needs to get refreshed in the page without actually clicking any refesh button.If possible please provide me with some page codes.

Code sample its up to you. Its a design issue and can be solved using RMI. The database sends an update flag to the registry object on the server.
The gui on the client side can be threaded for say every 100 mills seconds to download the RMI object from the sever and check the update flag. If true, to get the update field values with it.
Don't forget when you threaded to get the next update, to put a wait monitor till you get a response from the server and have a timeout just in case the server is not running, i.e restarted for example...

Updated attribute not showing up in the Front End

Hi,
I have to update an attribute column based on some conditions.
Even though I have updated, the updated value is not showing up in the front end
Moreover if I go to Diagnostics-> Examine and then query the attribute value I can see the updated Result
What can be the reason...
Please Advise
Rahul

Sounds like the Statement is not committed. Maybe you should add a
COMMIT;
at the end of your query.

Hi,
Welcome to SDN.
Could you give us information about the web application on the front end, is it using BSP ?
It sounds like you want to modify the standard, is that OK for you ?
Have you already located the BSP application (if any) in charge of the processing ?
Best regards,

Seriously: I am genuinely interested in why members of the BI and eBS community with no history of using the APEX forum persistently use this as a dumping ground for off-the-wall requests. If we can find this out then there might be a (remote) possibility of getting something changed on OTN to prevent it and avoid wasting everyone's time.

"No administrator found for the task" in the front end

Hi all,
My issue is, whenever approval request is raised from the front end ( JAVA WEB-DYNPRO), it triggers the workflow through the "sap_wapi_start_workflow" and when the workflow proceeds to the first level of approval, the front end application provides the approver with Approve and Reject options.
On click of approve, from the java webdynpro, the approve status is written in the container using "sap_wapi_write_container" and then a call is made to "sap_wapi_workitem_complete". Upon excution, the message line is "No administrator found for the task" and the return code is "1".
But if we do the same steps from the backend (R/3), the workitem is getting completed without any such error.
Please advice.
Thanks.

Hi Balaji,
I think I have an answer for you. This has happened with us when approving a WD java task using UWL (in our case for travel). The key is the return code of 1.
What has happened is this. The return code actually comes from the function SWW_WI_STATUS_CHANGE_NEW which is called deep in the WAPI wrapper. It means "infeasible_state_transition = 1".
This is due to the fact that after updating the container, your wapi call from web dynpro tries to change the workitem from status of "Ready" to status "Completed". This will not work.
What you will have to do is call "SWW_WI_STATUS_CHANGE_NEW" to set the status to 'SELECTED' beofre setting the item to complete.
The reason for this is that when you are executing from R3, the status change is done for you. When calling from the WD, no reservation of the workitem occurs.
Sorry about last night, I live well outside of town and the phone reception at my place is poor.

Problems with one of the front-end servers (service wont start)

Hi,
Having a pool with two front-end servers (Lync Server 2013 on Windows Server 2012) and I cannot get one of servers to work properly.
The Front-End service is not starting.
Have removed both servers from the topology and installed one at the time. When adding the second server to the pool the service never starts, its in starting state and a bunch of error messages appears:
- Server startup is being delayed because fabric pool manager is initializing.
Cause: This is normal when Pool is bootstrapped and indicates that the Front-End is waiting for a quorum of other Front-Ends to be started.
- Pool Manager failed to connect to Fabric Pool Manager.
Cause: This could happen because insufficient number of Front-Ends are currently active in the Pool.
I have tried restarted one at the time, both at the same time...
Reset-CsPoolRegistrarState -ResetType QuorumLossRecovery
Reset-CsPoolRegistrarState -ResetType FullReset
I have also had a look at the kb saying that there could be a certificate issue. So I have ran that script but no certificate is misplaced in any store.
I have removed the front-end certificates and requested new ones from the internal CA, I have also done the same to the OAuth certificates.
How to proceed?

Hi there,
if you are still receiving, the same error, please try to shutdown the first Front-End Server, and give time for the services to start, however I would like also to add that with Lync server 2013 the Enterprise pool requirements is to have 3 Front-End Servers
in a pool instead of 2, because of introducing the brick model architecture.

Speedgrade 7.2.1-direct link-GPU-real time color updates?

Hello,
Adobe says that SpeedGrade 7.2.1 now takes advantage of the GPU when Direct Linking a sequence out of Premiere.
Questions:
1. Does this mean I should see color corrections update in real time in my scopes and monitors the same way I see real time color updates in a native ircp SpeedGrade project?
2. I have a Black Magic DeckLink 4K Extreme card. Can SpeedGrade use my 4K card, or handshake with Mercury Transmit, so that I can get either an HDMI or SDI video signal output to my monitor?
3. I notice that for Premiere, adobe officially certifies GTX 690 for windows, and GTX 680 for Mac. Does this mean GTX 690 is not supported for Mac?
4. I tried right clicking on the SpeedGrade app, opening packet contents, and adding gtx 690 into cuda approved card list. That didn't seem to help. I did not try to amend the Open CL card list document, would that help?
Here is my system config:
Mac Pro Tower Early 2009
2 x 2.66 6-core Intel Xeon
48GB RAM 1333 DDR3
Cards:
Mac system report says all three of these are GPUs, however, my tech guy says the 640 is for GUI.
1. NVIDIA GeForce GT 640 (slot 2)
2. NVIDIA GeForce GT 690 (PCI Lane width x16)
3. NVIDIA GeForce GT 690 (PCI Lane width x16)
Cuda driver 6.0.37
Media storage is a raided 9TB serial ATA, about 300mbs read and write. Hard drive is even faster.
Adobe if you are listening, I'm trying to add SpeedGrade to my tool belt, especially since you did such a good job integrating the Tangent Element. The whole point of using SpeedGrade, as opposed to Resolve, is that the Premiere sequence links. I have access to everything, except AE comps.

Alright folks...I'm so close.
So, recap, getting real time performance and color updates using Direct Link in my external scopes and monitor, now that I'm on a Z800, windows 7 64 bit, with Quadro 4000, Cuda driver 394, AJA LHi card and break out box.
However, some problems still:
1. My internal SpeedGrade scopes are just a group of funky dots that kinda resemble my external scopes, viewing the same signal. Computer monitor resolution is 1920x1080. Tried other display options, still funky dots. Not a biggy, since external scopes are fine, just curious as to what's up with that? Is it because I'm using the latest Cuda driver 394, instead of an older one, since 4000 is old?
2 Do I need a LUT for SpeedGrade to output an HDMI video and SDI video signal in Rec709 2.4 gamma? Is it the handshake with the AJA LHI? Looks like it's spitting out sRGB 2.2 right now. I imported bars that I made in Symphony. These bars play out fine in Symphony and Resolve, through the same signal path SDI to the same monitor. However, in SpeedGrade whites are lower than a 100 and blacks are lifted. Since the bars in the external monitor look very similar to computer monitor, I'm assuming SpeedGrade is spitting out sRGB signal. Can't seem to insert the images I snapped, if they would help, I can email them.
3. Since there is no manual for SpeedGrade, I'm about to buy a 3rd party "class in a book" just so I can have some run down of what some of the settings and preferences options actually mean. Like what's "shaders?" Or why does it seem like framerate can be set in three different preference tabs? Would be nice if there was just a document with a run down of settings and preferences for both Premiere and SpeedGrade. Especially since I already have great turorials for the actual operaton of SpeedGrade like Patrick Inhofer's.
Thanks in advance. Wait....do you hear that....Adobe...is that you????

To avoid writing database code in the front end

Hello,
I am working on a database application using 10g database as backend and dotnet as front end. I wish to execute only oracle stored procedure for all the select (to avoid hard parse and use of bind variable), DDL and DML operations; just to avoid writing database code in the front end. Can anyone please give me a little examples of :
1.Select query's output to be return as resultset by stored procedure.
2.DML example by stored procedure.
3.Any DDL example by stored procedure.
using scott.emp, so that i would just call the stored procedure, rather than giving select,DML and/or DDL commands in the front end. Even though i have read in the documentation, but a clear cut examples will help me to get into clear concept as well.
Thanks & Regards
Girish Sharma

Hi...
-->Select example
create or replace procedure get_emp(rc out sys_refcursor)
is
begin
open rc for select * from emp;
end;
-->DML example
create or replace procedure do_dml_emp(pempid in number,
pempname varchar2,
result out number)
is
begin
insert into emp(empid,empname) values(pempid,pempname) returning empid into result;
exception
when others then
result:=-1;
end;
-->DDL example
create or replace procedure ddl_emp(colname varchar2,
coltype varchar2,
result out number)
is
begin
result:=-1;
execute immediate 'alter table emp add column ' || colname || ' ' || coltype ;
result:=1;

Diagram Not getting displayed on the Front End UI in SSM 7.5

Hello ,
We are running SSM 7.5 SP 04. We uploaded a custom image using diagram manager for the required context in the administration UI. The image is uploaded successfully. But , when I open the strategy tab for my context in the front end UI , I am getting a "HTTP 500 Page cannot be displayed error".
I restarted the listeners and the JPIP sessions as well. But still the error persists. Please advise.
Thanks and Regards
Vijay

Vijay,
It is possible to successfully upload a strategy map into Diagram Manager and still not see it in the User Interface. After loading the goal diagram has to be Published To Server. You do that in Diagram Manager.
You can upload a strategy map and Save that in Strategy Default in Administrator Interface, but unless you Publish it, it will not be exposed to the end users.
In the Set Strategy Defaults area of the Administrator Interface, in the Create or Edit Goal Diagrams section. The Goal Diagram you loaded should have a Publish Date next to it. If it says Not Published, you need to Edit that Goal Diagram in Diagram Manager,
In Diagram Manager under FILE at the top, choose Publish to Server.
You now should see a Publish Date in the Administrator interface and Saving it will now make it available on the user side.
Regards,
Bob

Lync 2013 Enterprise load balancing on the front end and edge pool

Hi,
I am setting up a Lync 2013 Enterprise deployment consisting of a Front End pool (x2 FE servers) and an Edge pool (x2 Edge servers). I'm seeing some conflicting advice regarding load balancing using hardware or DNS for the front end and the edge.
On the front end I have 2 internal DNS records 'lyncfepool1.contoso.local' each of which map to one of the IPs of the FE servers. I've used my details to populate the Detailed Design Planner excel spreadsheet and am told that I require a HLB to load
balance my front end pool. I'm aware of the need to load balance HTTPS traffic internally (which will be done by TMG) however other traffic to the front end (SIP, etc) can be balanced by DNS only, and not require a HLB?
Can someone clarify the front end requirement?
Also - looking now at the edge pool - this site again have two edge servers in a pool. We are using a total of six private IP addresses, two per edge service (2 x av.contoso.com, 2 x sip.contoso.com and 2 x webcon.contoso.com). These will be
NAT'ed by the external firewall and directed to the respective external (DMZ) IP addresses on the Edge servers on port 443. I know this isn't true roundrobin due to the intelligence of the Lync client when connecting (in that the Lync client will connect
to one of the public IPs and if it can't connect, it will know to connect to the other service IP), however I want to clarify this set up, particularly the need to direct the external public IP traffic at the DMZ Edge IP specified in the topology builder.
I've attached a basic diagram of the external/DMZ/Edge side which hopefully helps with this question
Persevere, Persevere, Per..

That is because you will always need HLB for a front-end server since it hosts the Lync webservices which use HTTP/HTTPS traffic.
The description on the calculation tool also describes this correctly:
Supports Standard and Enterprise pools (up to 12 nodes), with pure device-based load balancing or a combination of DNS load balancing and device-based load balancing (for
Lync web services)
You can use either Hardware or DNS loadbalancing for SIP traffic only, but you will always need a HLB for the webservices. Both are applicable for the Front-End so you have either
full HLB for both SIP and HTTP(S) traffic
DNS LB for SIP traffic and HLB for HTTP(S) traffic
Hope this is more clear :-)

Crystal Report not running from Addon in the Front End.

Dear All ,

Dear Rahul ,
In my system , there is a Addon , which has some crystal Report file inbuilt .

When we debug the Source Code and pass the event . . Report Open with no hurdle.
But the Same thing when we do at the From END of SAP , then it is not Returning any Report.

How do I create data-driven linkbuttons whose visibility is controlled from the front end?

I've made a component based on a mx:TitleWindow that contains linkbuttons that I'm using as a context-menu.
The TitleWindow component contains link buttons like this:
[Bindable]
private var _showEmailThis:Boolean = false;
[Bindable]
private var _showApproveThis:Boolean = false;
[Bindable]
private var _showReviewThis:Boolean = false;
<mx:LinkButton id="lnkEmailThis"
 visible="{_showEmailThis}"
 includeInLayout="{_showEmailThis}"
 click="lnkEmailThis_click()"
 label="Email this!" />
<mx:LinkButton id="lnkApproveThis"
 visible="{_showApproveThis}"
 includeInLayout="{_showApproveThis}"
 click="lnkApproveThis_click()"
 label="Approve this!" />
<mx:LinkButton id="lnkReviewThis"
 visible="{_showReviewThis}"
 includeInLayout="{_showReviewThis}"
 click="lnkReviewThis_click()"
 label="Review this!" />
This component contains a large number of links and is re-used by multiple modules in the same application.
Within each module, this component is used when a user clicks on a row in a datagrid.
The code looks like this:
In "Requests" module:
private function dgRequests_click(event:MouseEvent):void
 menu.showApproveThis = true;
 menu.showReviewThis = true;
In "Performance" module:
private function dgPerformance_click(event:MouseEvent):void
 menu.showEmailThis = true;
 menu.showReviewThis = true;
As you can see, the visibility of individual linkbuttons is controlled within each module by setting boolean properties.
If I alter this component to use a renderer, how can I control the visibility of the linkbuttons from the code in each module (there are over a hundred links with different functionality - not every link will be used in each module)? Note: it is not known from the back-end which grid within which module uses which link. This is set in the front end within each module's actionscript file.
e.g., if the XML looks like this:
<links>
 <link>
 <label>Email This</label>
 <visible>_showEmailThis</visible>
 </link>
 <link>
 <label>Approve This</label>
 <visible>_showApproveThis</visible>
 </link>
 <link>
 <label>Review This</label>
 <visible>_showReviewThis</visible>
 </link>
</links>
and I set the Email link to show in the module like this:
private function dgPerformance_click(event:MouseEvent):void
 menu.showEmailThis = true;
How do I make it take effect? Is there a way to control the visibility of a linkbutton within an item renderer in a component from the module that uses that component? Is there something like reflection in the Flex framework?

Put a single frame sequence structure around your stop button and then wire from the error cluster going into the error handler to the edge of the sequence structure. Now your code will stop at the end of the current iteration. To see why this works, watch you code execute with execution highlighting turned on and review the section of the manual talking about "Dataflow".
