Real Time Refresh Data in Dashboards

Hi
How I can see near to real time refresh data in the OBIA Dashboards?
Scheduling ETL over night only show the data posted a day ago.

Naeem Akhtar

Hi,
In order to show fresh data in dashboards(not from cache) we go for event polling table.
Using Event Pooling will run the incremental Load to show real time data?No it dosent run any incremental load, it purge cache to show fresh data in dashboards
Go through below guide which will help you out -

How to implement real-time refresh datas in obiee?

Can you elaborate more...
If you want to see refreshed data in OBIEE Reports, you need to implement Caching mechanism based on how you often refresh warehouse..

How to read updated data from a real-time generated file?

I have a question:
I want to read the 10 mostly updated data from a real time generated data file. The data in this file is accumulated. how can i read mostly recently data to an applet? and further to using this data to draw a real-time graph? pls help

Hi,
I think there is no "typical" way. You will have to define a convention on how the new data are stored into the file, so as to know how to accessthem. If new data are simply put at theend of your file, you may use a RandomAccessFile to read only those lines that interest you (the 1 final lines).Otherwise, you should at least know how the data file is written.
You can know if thedata file has been modified with the File.lastModified() method. This retrurns a long value corresponding to the date and hour the file was last modified. Store that value ito you appl. and perdiodically (use a Thread), compare that value with the value returned by lastModief(). If both value are NOt equal, then the file has been updated
it's all a question of knowing how the data are stored into the datafie generated.
Be also aware that you will probably have problem when your java appl. tries to read the file at the same time it is updated by the other application. I guess when theother application writes data into the file, you will not be able to read it. So, use try{} catch statements and first check to see if you can read the file with File. canRead(). If not, simply delay the reading process by asking a Thread.yield() or Thread.delay (1000)...

Can we use remote cubes for real time data

Hi Gurus,
Can you please explain, can remote cubes be used for sales item and billing item ,data sources, if it, can i extract the data as of normal cube running on these DataSource, if so then i want to make multicube on normal cube and remote cube and make a real time sales data on BW, please explain the possibilities of this, we are on version 3.1c
Thanks in advance

Hi,
Remote cubes are special InfoCubes. A Remote cube represents a logical view.
Unlike with BasisCubes however, no data is physically stored in SAP BW. The
data is taken from the source systems only after a query has been executed.
There are three types of remote cube. They can be distinguished by the way
in which they retrieve data.
Overview: Virtual Cube Types
-SAP RemoteCube
A SAP RemoteCube allows you to define queries with direct access to transaction data in other SAP systems.
-General RemoteCube:
A general Remote Cube allows reporting using data from non-SAP systems. The external system transfers the requested data to the OLAP processor via the BAPI.
-Virtual InfoCube with Services:
For a virtual InfoCube with services, a user-defined function module is used as the data source.

UCCX 8 - CSD Real Time Display "N/A"

Hello,
We are facing an issue with Cisco Supervisor Desktop real time display "Agent Logs - call" and "Agent Logs - state". These two real time displays show "n/a" while select specific agents (some agents it show data as normal). For the agents who display "n/a" in CSD, in CAD the real time data display as normal.
For example: When supervisor monitor Agent_A in CSD "Agent Logs - call" show "N/A" (the same to Agent Logs -state). But in CAD, Agent_A can see real time display "Agent Call Log Display" as normal (the same to "Agent ACD State Log Display").
Does anyone experience this issue?
It seem that the real time display data in CAD and CSD are getting from the same source. How come the CSD show "n/a" when the data is available in CAD? Any idea, please help.
Many thanks,

Hi Anuj,
Thanks for your response. We are currently running on UCCX SU2. We used to reinstalled CSD/CAD already after we upgrade the UCCX to SU2. Our issue is now fixed by delete the user id of inactive agent from resource page and resync the directory services.
Just a note for anyone who might face similar issue, the recommendation is to first check the version of CAD/CSD running on the client PC (as Anuj suggest) and also comparing the user ID with the UCCX resource page. Be aware that user ID is case sensitive. Check the inactive agent list in the resource page. Delete the user id if you see it there. Then go to Desktop Administrator to resync the directory servcies.
Thanks!

How to show two different plots with current system time and date on waveform chart

I am using one waveform chart to display the more than one value continiously. The data are comming properly but i am not getting my system (pc) time and date on x axis. It is showing default date and time (i.e.01/01/1904 5:30:45). Please give me suggestions to display the real time and date on x axis of waveform chart.

How does your data look like? Do you graph waveform data types, dynamic data, or plain arrays/clustes? In the case of plain arrays, you need to set x0 to the absolute start time of your data, e.g. with a property node.
I you would attach your code (or an image) we could offer more specific advice. There are too many possibilities.

Real Time Communication

HI Gurus,
Can any one tell me what is REAL TIME COMMUNICATION.
Also I request information / details on RTCIS.
Regards
Ajoy

Hi Ajoy,
1.1 Application Scenarios for Real Time Communications
There are two classes of applications: client and server. Client class applications have one real-time client per computer, such as the traditional instant messenger (IM) application. Server class applications typically act on behalf of multiple users or communicate with many hundreds of users simultaneously. Server class applications are often based around intelligent applications that interact with users. These applications can be divided into two categories: notification Apps that send information to a client and interactive Apps that accept and respond to a client. A third type of server class applications, Web-based clients, interacts with users through a Web server.
1.2 Notification Applications
Notification Apps are real-time applications that send information to multiple clients from a centralized server (see Figure 1). The one-way transmission means that clients cannot communicate directly with the notification App. Instead, clients must choose which events they wish to receive by using some other technique, such as a Web application.
One example of a notification App is an application that notifies all of the users of a particular e-mail server that the server is about to go offline. Another useful notification App would send alerts in cases of severe weather.
1.3 Interactive Apps
Interactive Apps are applications that allow multiple clients to communicate with a central server in real-time, as Figure 2 shows. They are different from notification bots in that interactive bots support two-way communications with a client. Using this approach, you can build an application that interacts with users in real-time. Within this scenario, there are two main sub-scenarios. The first provides a user with information and waits for the user to respond, such as an application that notifies users about changes in stock prices and then gives the user the option to buy or sell. The second waits for the user to request a session with the App and then responds to requests that the user supplies, such as a calendar application that allows a user to schedule meetings and other events while receiving reminders just prior to the meeting or event.
1.4 Web-Based Clients
Web-based clients provide the same basic functionality as the traditional IM client through a Web interface, thus allowing the widest possible audience to use the application, as Figure 3 illustrates. It also has the side effect of eliminating the need for a user to download local software, which reduces user concerns about the download containing a potential virus. These types of clients are useful to organizations that wish to provide a Web-based front end to their internal IM system. For example, a company might wish to use a Web-based IM client to connect customers with a support group. Doing so maximizes the number of customers that can connect with the support group.
Real Time Communications Data Flow
It's critical that organizations planning large deployments of real-time communications applications ensure that those applications can scale to meet the desired goals. The RTC Client API is very efficient for client class applications for which each client runs on its own computer. To build a scalable RTC Client API application that services multiple clients with a single computer, you need to ensure that the application is scalable when you design it.
The Real-time Communications (RTC) Client API is a set of COM interfaces and methods designed to create PC-PC, PC-phone, phone-phone audio/video calls, or text-only Instant Messaging (IM) sessions over the Internet. Application sharing and whiteboard (An application that displays a window for two users to exchange information) can also be added to PC-PC sessions. Presence information is used to track the location of buddies (or contacts) for communication purposes. This information is available through the RTC Client API on a SIP registrar server.
The RTC Client API:
1.Supports multiparty phone-phone calls
2.Uses SIP-based signaling and presence communications
3.Integrates with the Microsoft Office RTC proxy and registrar server
4.Supports provisioning with ITSPs or third-party corporate-deployed servers
5.Integrates signals over IP and PSTN networks
I hope this will be useful for you.
Thanks,
Swamy Kunche

Infocubes - TRANSACTIONAL - STANDARD - REAL TIME

<h3>Some clarity has to be brought in to these three types of CUBES.
<h5>
I am using SALES ANALYSIS & SALES BUDGET here as an example.
<h1>Assumptions & Scenario:
<h5>1. Sales Budget is prepared once a year, Division / Group / Category / Material wise (may be customerwise, but does not really matter). Once the budget is approved, it more or less remains static, with very little changes. Budgeting is done for Quantity to be sold as well as an approximate unit cost.
<h5>
2. Sales Analysis captures the actual sales in the same order Division / Group / Category / Material wise but now the quantity and the unit price are actual values.
<h5>
3. Assume that the accounting period for this organization is January to December for a calendar year, and the Sales budget is finalized and approved in November for the next Accounting year. Example, sales budget for Jan, 2010 - Dec, 2010 is finalized and approved in November, 2009.
<h5>
4. Review and fine tuning and updates to Sales budget is carried out once in three months for the next quarter. In the case in Mid March, Mid Jun, Mid Sep.
<h1>BI Requirement:
<h5>1. Actual sales figures are always compared with Sales Budget and also compared with Last years Actuals.
<h2>
Solution Scenario - I.
<h5>
Maintain Sales Budget figures in a separate INFOCUBE, FACTS being quantity and value, Dimensions being Division / Group / Category / Material . (since there is very little update to this cube, SHOULD WE CALL IT STANDARD or REALTIME or TRANSACTIONAL)
<h5>
Maintain Actual sales in another INFOCUBE, again FACTS being quantity and value, Dimensions being Division / Group / Category / Material . Because of the Data Volume, we want to update this cube on nightly basis, using DELTA. Should we call this STANDARD or TRANSACTIONAL ?
<h5>
All the reports, queries will JOIN (dont know how) both the cubes and display BUDGET and ACTUALS in adjacent collumns.
<h2>_Solution Scenario -II._
<h5>
Since the BUDGET figures and ACTUAL figures are always viewed together, create a single INFOCUBE for this department.
<h5>
FACTS being BudgetQuantity, BudgetAmount, ActualQuantity and ActualAmount. (include if you want, some computational fields to show Percentage of Variance which can also be done at the query level). DIMENSIONS remain the same as SCENARIO - I.
<h5>
You will note immediately that TWO OF THE FACTS are almost STATIC while two of the FACTS are updated everyday.
<h5>
What would you call this type of CUBE? TRASACTIONAL / STANDARD / REALTIME ?
<h5>
Difference between STANDARD and REALTIME cubes being the way the INDICES are maintained. (Hope my understanding is correct, one designed for better performance for RETRIEVAL and the other for UPDATE).
<h5>
In all the cases (Transactional / Standard / Real time) the data is moved from R/3 to PSA and then to the INFOCUBE. so why use the term REAL TIME. And cubes are always built based on Business Transactions, so why use the term TRANSACTIONAL?
<h5>
The term "Real Time" somehow conveys the idea that the CUBE Gets updated, when a transaction is Committed in R/3 database. The Help document also is Ambiguous. If the data is moved from R/3 to Data Source and then to PSA and finally reaches Infocube, then what is REAL TIME?
<h5>
I think it would benefit everyone in SAP BI domain, if these things are explained in plain english.
<h5>
I apologize for writing such a long QUESTION , but hope it will help many of you,

Save file real time

hello
i was having problem with the saving file real time. the data is
desired to be saved in the form of spreadsheet. using the date and time
as file name, the file will be saved automatically. i do not what has
gone wrong as it can be used to save file offline.
it appears the message of
ERROR 8 occur at create file (file exists) (althought it does not exist)
NI 488: DMA hardware error detected
here attached the error message
someone pls help
thanks
regards

It is difficult to tell from the small segment of code shown, but it appears that the New File function is in a loop. Is it possible that the loop iterates quickly enough that it attempts to create the file twice with the same time? One way around this it to check first to see if the file exists. If it does, than append a 1 (or 2, or 3, or ...) to the filename and try again.

Call web service from OBI dashboard to show real-time data alongside data from DW

Hello,
OBI = 11.1.1.7.0
We have a requirement to pull in real-time data from an external, secure web service (WS) into an OBI report. The OBI report also contains data from the data warehouse (DW) along with a calculation that is derived from multiplying the DW and WS data . In theory, the behavior that were looking for is similar to the Action Link "Invoking a web service" whereby the call is made to the web service for each row of data. How would it be possible to achieve this result on an OBI report?
Desired Result of OBI Report
Product.......Qty.........Price........Potential Revenue
TV..............100...........$500..........$50000
VCR.............22............$75...........$1650
DVD..........2500............$20..........$50000
Breakdown of the data source for each column on the OBI report
Product.......Qty.........Price........Potential Revenue
DW............WS...........DW..........Calculated_on_the_fly_(qty*price)
DW............WS...........DW..........Calculated_on_the_fly_(qty*price)
DW............WS...........DW..........Calculated_on_the_fly_(qty*price)
Thank you,
Mike

Does anyone know if it's possible to call a webservice from an OBI report to populate a column's value? Thank you for your input.

Need Suggestion On Real Time Data Accees

Hi,
Our application (let say A) runs on * 8.1.7.4.0*
Another Application (let say B) runs on *10.2.0.4.0*
Both the application A and B exchange data through DB links.
Both the application A and B perform select and DML on other tables.
Application A has views (approx. 10 views) on application B 's table through DB links.
Application B also has views (approx. 50 views) on application A 's table through DB links.
Application A has store procedure (approx 10 SPs) through which it does insert/update on two of application B 's table approx 15K call of that procedure per day.
Application B also calls some of the application A 's procedure to insert/update data in application A 's table.
Currently both the application's data center are at the same place. But, there is a proposal/need to move application B's data center far away from the current location. Because of these we are in a assumption that DB Link over WAN will create performance issue and searching of probable replacement.
After of couple of discussion we have identified approx five application A 's tables which are frequently accessed by application B and expect real time data.
Similarly, Application A expect real time data from two application B 's table.
'Golden Gate' mechanism came in our discussion, butt it's expensive,
Can we replace this store procedure code/dml with web service call or so ??
Can anyone suggest ... what kind of approach we should take here ?

Views which are residing in application A 's side use many internal tables and one or two application B s table.
I don't have idea on 'multi-master replication ' ... is it two way replication ..? ... you aware of any documentation I can refer ..? How costly it is (if you can give an idea) ?
Also, among many tables we need near real time (2 mins interval) replication on 5 tables.
MVs again have dependencies on DB link, which exactly what are trying to replace (assuming performance issue)
With fast refresh (let say 2 minutes interval) method on MVs do you think it could cause performance issue specially when data center are at different location ?

How to calculate rms voltage, rms current and frequency from real time data?

Hello,
I need to calculate the real time rms voltage, rms current and frequency of the received voltage and current graphs using visa read. Actually am trying to monitor the voltage and current parameters of AC load, in this case, am using a set of 4 light bulbs at the moment. Expected frequency is 50 Hz, and rms voltage close to 240v AC, current about 1A.
Attached is the vi picture of what I have been able to achieve so far, courtesy of labview forums. But I need to finally finish this vi by calculating the Vrms, Irms and frequecy. The front panel shows the voltage (Chart V) and current (Chart I) after scaling. Chart VI represents ADC value 0 ~ 1023 of received data. Aray V & I show the binary bits received up to 10 bits of useful data from ADC. Each sine wave from ADC is sampled at 25 samples for the ADC conversion, and sampling frequency of 1.28kH.
I have tried using the RMS vi, but seems I don't know how to configure it correctly to get desired results. Also when I make changes like switching of one of the bulbs so that their is current change, I need to refresh the SERIAL port first before changes show up on the VI. Any ideas on how to improve on this are highly appreciated.
Otherwise, I would appreciate if somebody helps me MODIFY my VI to read the rms values and frequency from received data. This is the last piece of my project, I do appreciate all the help rendered. Am currently using labview labview 2014, student version!
Gavin.

Last Refresh Date/Time

seems like this should be simple enough but i can't figure it out.
i have a dashboard with a refresh button. the dashboard uses a LiveOffice universe query. the user would like to add something on the dashboard that shows the last date/time that it was refreshed. i can show the initial load date/time by using a text box and linking it to a cell with =now() formula but it doesn't change as the model is refreshed.
i guess i could put something in the universe and query it for the current date/time but that seems like an awful lot of work. any ideas?

This depends on your LO Data Source. If you are using a Web Intelligence Report, you can define a Variable with:
=LastExecutionDate()" "LastExecutionTime()
And then use a label on your dashboard pointint to where this is located on you spreadhsheet from the report.
