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..

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.
Regards
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 Integrate real time data between 2 database servers

How to Integrate real time data between 2 database servers
May 31, 2006 2:45 AM
I have a scenario where the data base (DB2 400) is maintained by AS 400 application and my new website application based on j2ee platform access the same database also but the performance is very low. So we have thought of introducing new oracle data base which will be accessed by j2ee application and all the data from db 400 database will be replicate to oracle data base. In that scenario the only problem is of real time data exchange between 2 databases. How do we achieve that considering both the application As400 and j2ee website application are running in parallel and accessing the same information lying on DB2 400 database. We have to look at transaction management also.
Thanks

You certainly wouldn't use XML for this.
The process you're looking for is called "replication". Ask your database experts about it.
I predict that after you spend all the money to install Oracle and hire consultants to make it replicate the DB2/400 database, your performance problem will be worse.

Yeajh I now that its not a XML solution.
Replication is one of the option but AS400 application which uses DB2/400 DB is highly loaded and proposed website also uses the same database for retrieval and updation purpose.All the inventory is maintained in the DB2/400 database so I have thought of introducing new oracle database which will be accessed by new website and it will have all the relevant tables structure along with data from DB2/400 application. Now whenever there is a order placement from new website then first it should update the oracle database and then this data shuold also migrate to db2/400 application at real time so that the main inventory which is lying on db2/400 should be updated on real time basis because order placement is aslo possible from As400 application. So the user from As400 application should not get the wrong data.
Is it possible to use MQ products??

Hi,
the answer to your question is not easy. Synchronization or integration or replication data between 2 (or more) database servers is very complicated task, even though it doesn't look like.
Firstly I would recommend to create good analysis regarding data flow.
Important things are:
1) what is primary side for data creation. In other words on which side - DB2 or Oracle - are primary data (they are created here) and on which side are secondary data (just copies)
2) on which side are data changed - only in DB2 side or only on Oracle side or on both sides
3) Are there data which are changed on both side concurrently? If so how should be conflicts solved?
4) What does it mean "real time"? Is it up to 1 ms or 1s or 1 min or 1 hour?
5) What should be done when replication will not work? I mean replication crash etc.
BTW. The word "change" above means INSERT, UPDATE, DELETE commands.
Analysis should be done for every column in every table. When analysis is ready you can select the best system for your solution (Oracle replication, Sybase replication server, MQ, EJB or your proprietary solution). Without analysis it will be IMHO gunshot into the dark.

How to Implement a Time Limit Feature in an Online Test Application ?

I am creating an Online Test application. The time limit can be stored for a Test in the database.
How to implement a time limit such that when the test is started (user clicks on the Start button to go to the fragment containing the Questions) the time left is shown and the test ends (goes to home page) when the timer reaches zero.

Hi,
timestamp is a date and thus cannot be used directly to determine seconds passed. So what you need to do is to build the difference between a saved time stamp and the current time.
http://docs.oracle.com/javase/1.4.2/docs/api/java/sql/Timestamp.html
So if you have two time stamps, then calling getTime() on each and building the difference gives you a value, which is millisecond. So to get this to an int value you divide it by 1000

How to use Real time execution trace toolkit with Dual-core processor??

hi there
the situation as follows:
i have a computer (PC and Laptop) types with Dual-core processors, and am trying to do simulation using Multi-core technology and based on different simulation scenarios...starting from sequantial processing,.......Piple lining processing strategy. so that i can differentiate the time delay between those types of processing based on (Using 1 processor then dual-core processor Computers)
my question is: As i read through Ni's white papers i saw many notes refer to Real-time execution trace toolkit to investigate the (processing-time , etc) of multi-core processors in processing diffenent algorithms. My algorithms are to be run on 1 computer with dual-core processor BUT, not in real time environments, that is ( No hardware to be connected to my pc) only algorithms running on my pc....
So, is it possible to use Real time execution trace toolkit or anyother tools in LabVIEW to show processing-delays and/or anyother timing critical issues without using my application for real- time hardware.???
in other words: how to use Real time execution trace toolkit in non-hardware and/or real-time scenarios???
please help me in this.
Any suggestion, comments, feedback.....is absolutely highly appreciated
thanks a lot in advance
Labview Lover

Hey,
The Realtime Execution Trace Toolkit only works for NI RT Targets.
But you can use the Desktop Execution Trace Toolkit, just search for it under ni.com.

How to make real time chat in ios

Hi ,
I want to implement real time chat in ios app.

Hi Sunil,
You have (at least) two options:
1) use the XMPP protocol (XMPPFramework and a Jabber server like OpenFire). See ChatSecure (https://chatsecure.org/about/) and it's source code for further guidance.
2) use a service like QuickBlox (http://quickblox.com/modules/chat/)
Good luck!

How to get current time and date??

How to get current time and date from my PC time and date to the java application??
i use java.util.* package but got error, that is:
- java.util.* and java.sql.* class are match
- abstract class cannot be instantiated
so what can i do, pls guide...thanks...

There is a method in the System class that will return the current system time. You could also instantiate a Date, Time, Timestamp, or Calendar object, all of which get created with the system time by default.
Don't import *. Import the specific classes you need.
Next time, post the actual text of the exceptions/compile errors. If you make people guess, most just won't bother.

How do I transfer time capsul data to external hard drive to free up space?

How do I transfer time capsule data to external hard drive to free up space?

The fastest method is straight copy and paste..
Plug a suitable hard disk into your computer.. format it Mac OS extended journaled (if not already).
Select the folders/files you want to move.. copy and paste them to the external drive..
Double check that the files are copied because the next step will delete the files forever.. there is no trash on the TC.
Delete the files on the TC.
You can also do a full archive of the TC disk to a USB plugged into it by USB.. it must be formatted Mac OS Extended Journaled. It must be big enough to hold all data on the TC disk.. best idea is to buy the same size or bigger.. so if you use 2TB TC buy a 2TB or bigger external drive.
In airport utility select archive.
That will copy everything on the TC disk to the USB drive.. you could then Erase the disk of the TC.. this is super fast if you choose quick erase.. just a few minutes. But the archive will take many hours.. say for 2TB about 12-24hours.. and you cannot use the disk in the TC during that time.

How can you build time series measures in OBIEE without using TODATE AGO fu

How can you build time series measures in OBIEE without using TODATE and AGO function?
Please provide steps to build time series

sysdate and some simple calculations. Please
send your inputs/ideas for my questions..
Thanks in Advance

This can be using Msum function in answers. Use the following formula, here dollars is my metric. Change the formula based on your metric.
Msum("Sales Measures".Dollars ,2) - "Sales Measures".Dollars
the report will be cached and better performed compared with time series. check ti

How to get real time date from Sunny Boy Inverters through SMA Webbox?

Hello,
I was looking on how to communicate with three Sunny Boy Inverters that are linked to a SMA webbox. Currently we get a daily summary of the solar production, but we would like to have real time data uploaded into LabVIEW. The people of SMA said that I needed to use "RS485 protocols" with a software they have called YASDI (http://www.sma.de/en/products/software/yasdi.html); however, I keep finding other information that says that I can communicate with my inverters using the SMA OPC server (http://www.sma-america.com/en_US/products/software/sma-opc-server.html). I also found this forum, http://forums.ni.com/t5/LabVIEW/Sunny-Island/m-p/809129/highlight/true#M368718, where I understood that I don't need to use the OPC server, but instead I can use UDP communication to get the data. I found another forum that talks about using the YASDI :http://forums.ni.com/t5/LabVIEW/help-with-Sunny-Boy-inverter/m-p/293273/highlight/true#M153892.
I've tried to communicate with the people of the forums and I haven't gotten any responses; therefore, I wanted to see if I can get cleared up on this issue. Do I need to use OPC server to communicate with my inverters through the webbox or can I just use UDP in LabVIEW?
Any help would be greatly appreciated,
Thanks
Jose

Hello,
I got a response from Vincezo: http://forums.ni.com/t5/LabVIEW/Sunny-Island/m-p/1794786. I'm currently working with the VI to communicate with the webbox through UDP. Since the PRC protocols to communicate with the webbox are in JavaScript Object Notation (JSON), I'm not sure if the data-in string has to be in JSON format. However, the only error I'm getting is 56 in the UDP read function. I've tried increasing the size of the bytes and timeout, but I keep getting this error. If anyone can help me with this part I would very grateful.
Thanks,

Has anyone implemented real time datasource for COPA ?

Hello,
Has anyone implemented a real time data source for COPA ? Please share details of the process for how this can be set up. Thanks.

Hi,
Please follow the following steps...
COPA Extraction
The below are the command steps and explanation. COPA Extraction -steps
R/3 System
1. KEB0
2. Select Datasource 1_CO_PA_CCA
3. Select Field Name for Partitioning (Eg, Ccode)
4. Initialise
5. Select characteristics & Value Fields & Key Figures
6. Select Development Class/Local Object
7. Workbench Request
8. Edit your Data Source to Select/Hide Fields
9. Extract Checker at RSA3 & Extract
BW
1. Replicate Data Source
2. Assign Info Source
3. Transfer all Data Source elements to Info Source
4. Activate Info Source
5. Create Cube on Infoprovider (Copy str from Infosource)
6. Go to Dimensions and create dimensions, Define & Assign
7. Check & Activate
8. Create Update Rules
9. Insert/Modify KF and write routines (const, formula, abap)
10. Activate
11. Create InfoPackage for Initialization
12. Maintain Infopackage
13. Under Update Tab Select Initialize delta on Infopackage
14. Schedule/Monitor
15. Create Another InfoPackage for Delta
16. Check on DELTA OptionPls r
17. Ready for Delta Load
LIS, CO/PA, and FI/SL are Customer Generated Generic Extractors, and LO is BW Content Extractors.
LIS is a cross application component LIS of SAP R/3 , which includes, Sales Information System, Purchasing Information System, Inventory Controlling....
Similarly CO/PA and FI/SL are used for specific Application Component of SAP R/3.
CO/PA collects all the OLTP data for calculating contribution margins (sales, cost of sales, overhead costs). FI/SL collects all the OLTP data for financial accounting, special ledger
1) Add the fields to the operating concern. So that the required field is visible in CE1XXXX table and other concerned tables CE2XXXX, CE3XXXX etc.
2) After you have enhanced the operating concern then you are ready to add it to the CO-PA data source. Since CO-PA is a regenerating application you can't add the field directly to the CO-PA data source. You need to delete the data source and then need to re-create using KEB2 transaction.
3) While re-creating the data source use the same old name so that there won't be any changes in the BW side when you need to assign the data source to info-source. Just replicate the new data source in BW side and map the new field in info-source. If you re-create using a different name then you will be needing extra build efforts to take the data into BW through IS all the way top to IC. I would personally suggest keep the same old data source name as before.
If you are adding the fields from the same "Operating concern" then goto KE24 and edit the dataaource and add your fields. However if you are adding fields outside the "Operating concern" then you need to append the extract structure and populate the fields in user exit using ABAP code. Reference OSS note: 852443
1. Check RSA7 on your R3 to see if there is any delta queue for COPA. (just to see, sometimes there is nothing here for the datasource, sometimes there is)
2. On BW go to SE16 and open the table RSSDLINIT
3. Find the line(s) corresponding to the problem datasource.
4. You can check the load status in RSRQ using the RNR from the table
5. Delete the line(s) in question from RSSDLINIT table
6. Now you will be able to open the infopackage. So now you can ReInit. But before you try to ReInit ....
7. In the infopackage go to the 'Scheduler' menu > 'Initialization options for the source system' and delete the existing INIT (if one is listed)
