Oracle reports in real time?

can any one brief me about the kind of oracle reports do they generate in real time?i.e d2k reports . . iam facing tough to answer these questions in interview?can anyone examples abt use of it in real time?

at my work i use dev suite 10g on windows, and the application server is also on windows.
i compile the fmb into an fmx directly in forms builder. open the form in forms builder and the option is in program->compile module on the menu.
there is also frmcmp which you can run, which can also compile the fmb.
once i have the fmx i just copy it to the server into the directory where our forms expects it to be (you can see that in the forms server configuration - FORMS_PATH)
as for the reports, we're still a throwback to the the good old days, so all our reports are still in .rdf format. this does not need any compiling as the reports server will do that when it is executed. so like the .fmx, i just copy it to the directory where our reports server expects it (again you can see this in the reports server configuration - REPORTS_PATH)
we're just a small shop, so there are probably better ways to do this, but that's how we do it. be happy to hear how others do it...

Calling Oracle Workflow in Real-Time

I want to modify the logic in Oracle Apps (both Oracle self-service (pure HTML and JSP) and Oracle Forms applications) to make real-time calls to a mainframe system. The page needs to take different actions depending on the data from the mainframe system.
I want to avoid actually customizing the Apps and Forms pages if possible due to customization maintenance and support issues. I have been told that I can use Oracle Workflow to modify the actions of the pages without having to resort to customizations, as calls to Workflow are already embedded. Is this true, and if so, how would I go about inserting a call to a mainframe system?
I am considering mainframe calls using either a proprietary ODBC driver from a third-party vendor, or devising some sort of SOA interface to the mainframe (I know it would require custom development on the mainframe side).
Thanks!

I'm pretty sure the sbRIO cards only have 1 FPGA on them. So when you load the second FPGA code, the first is being overwritten. You need to make a single FPGA VI that can handle both functions. If you post your code, we can give more detailed advice.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

Oracle Data Integrator - Real Time Integration

Hi,
I want to know that, is there any possibility of integrating data in real-time using Oracle Data Integrator?
If yes, does it affect the OLTP system performance? (Could it read from db logs,etc..)
Thanks..

Using ODI with Logminer-based CDC will affect performance on the source system more than using Oracle Goldengate, let me explain why:
When using the ODI Logminer-based Journalisation the Logminer functionality will move the primary-key of the affected row into the journal table. When you are then ready to move the changed data, running an interface to move the data reads the Journal-view, which joins the journal table (primary keys) to the source data (and dealing with deleted rows), optimising out duplicate rows in order to bring across the then-current state of the data, which can then be loaded into the target system, on completion, the moved rows can be removed from the journal table. The data will appear in the journal table as soon as Logminer puts it there, which may be a lag of up to two minutes using asynchronous setting, whereas Synchronous Logminer applies "system triggers to the table, with the consequent overhead.
With Oracle Goldengate, the comitted transactions are read from the log as soon as the log-writer puts the commit into the log. All the data is picked up from the log, at that point. It is then written to the trail-file system of Oracle Goldengate which can be propogated to multiple other systems potentially with sub-second latency, and minimal impact on the source system due to the efficient reading and writing mechanisms. One other consequence of using Oracle Goldengate is that you get every change of the data, not the optimised then-current state of the data when moved.
Hope this explanation helps.

Can Oracle run in real time OS(such as PSOS) and communicate with data server by OCI?

Hi, all!
i have a question to get your help! now my oracle client running in SUN solaris communicate with oracle data server by OCI(oracle call interface). In future, my client system will port to embeded system that will use real time OS, such as PSOS, so i'm afraid that is OCI communicating with data server ok in PSOS environment??? Is there a special driver or OCI lib for PSOS?
thanks very much!!!
null

I have no idea which platforms the Oracle client has been ported to. If there exists an Oracle client for PSOS, then you should have no problem with OCI there. If there's no Oracle client for PSOS, then you won't be able to make OCI calls.
Regardless, this probably is a question better addressed to Oracle sales rather than to an ODBC forum.

Report on Real Time Cube and Master data

Dear Experts,
I am new to BI. I have created real time cube using some characteristics and top of that I built 3 reports with referring to Master data.
And in the 3 reports, I have used different characteristics for all the report expect one ( common in all the reports).
Now I have to create consolidated report using all the characteristics. I have build some sample reports but getting not assigned where there is no data.
How can I achieve this?
Thanks in advance,
Saravanan R

Hi suman,
Thanks for your reply .
I have attached the screen shot of the output. I have created the Infoset using info objects and real time cube, on top of that I have created query.
this is the problem am facing can please suggest on this .

Internet bandwidth usage reporting in real time

Need some guidance with regard to software selection and physical layout. I've been asked to provide reports on internet usage;
- IP address
- port/protocol
- bandwidth
We havcusco cisco 4500.
Our ISP router is 3400 metro router (fibre to Ethernet media converter).
We have the ISP connected to a port on the 4500 in vlan 99, the users are in vlan 44 (using a virtual layer 3 gateway).
If I want to do just a quick capture could i simply connect a workstation with wireshark to a port on the 4500 and place that port in vlan 99?
If so I assume the same theory would work with tool like bandwidthD that is more suited to long term captures and has a nice pretty GUI for my manager?
Bit confused as to whether I need a mirror or span port setup.
Thanks

You'll need to configure SPAN with VLAN 99 as the source and the port your reporting workstation is connected to as the destination. Otherwise most of the traffic will never reach the reporting workstation.

Oracle fail safe real time users

hello,
Please let me know about some oracle fail safe users
Thanks in Advance,

hi rahul,
i think i have sent you some links and documents for oracle fail safe case studies...haven't they of any use?
you can refer oracle docs and can raise the SR with oracle support if you come across any issue and disaster recovery situation....
please check the documents i have given to you
and rather looking for customer case studies you should look for oracle fail safe specific doc as it is recommended by oracle, client or customer may adjust oracle fail safe architecture according to their environment, but oracle docs insist you to make environment required for oracle fail safe.
have a look for this oracle case study

Best practice for real time requierement

All,
I am trying to find out what is the best practice for reporting against real time data ?
is it while using
1 - webi against universe/bex query on the top of hybrid cubes ?
2 - Crystal report directly against the ECC data ?
3 - using another solution such as Data Fedrator ? or something different ?
I am looking to know if anyone got such req and also to share their experience
did they get some huge challenge against hybrid cubes ?
Thanks in advance for your help
Philippe

Well their first requierement was to get real time data .. if i am in Xcelsius and click refresh then i want it to load my last data ..
with live office , i can either schedule a crystal report and get the data delayed or use the option from live office to make iterfresh as right now .. is that a correct assumption ?
I was talking about BW, just in case they are willing to change the requierement to go from Real time to every 5 min
Just you know we are also thinking of the following option:
1 - modify the virtual provider on the CRM machine to get all the custom fields needed for the Xcelsius Dashboard
2 - Build some interactive report on the top of these Virtual Provider within CRM
3 - get the link to this report , it is one of the Report feature within CRM
4 - design and build your dashboard on the top of it
5 - EXport your swf file to the cRM web ui
we are trying to see which one is the best one

Need to monitor any file change in the system, in real time

Hi,
I am running a program that I suspect may be doing changes in the filesystem, but I do not know which ones. I would like to know if there is a daemon/program that could help me monitor those changes. I tried AIDE, however, it works by creating a database of checksums for each file and does not report in real time potential changes. I would rather use a program that logs changes and timestamp them. Furthermore, AIDE is not useable with /var files, since there are many of them and they change so often. Is there another good solution?
Alternatively I would like to run the program with monitoring. For instance, run the process as:
monitor_program my_program_to_monitor logfile
This would dump in logfile what my_program_to_monitor does to the filesystem.
Thanks in advance.

no, at least with inotifywait, it is not possible. once you know what file is being changed you can use "lsof" to see what process have opened that file.
i tried the following to search lsof output first thing when inotifywait finds a file change.
file=$(inotifywait -r /home/mang/watch --format %w | sed 's/.$//'); lsof | grep $file
while in another terminal running "vi /home/mang/watch/test"
the output is:
zsh 12574 mang cwd DIR 254,11 4096 4723089 /home/mang/watch
vi 16790 mang cwd DIR 254,11 4096 4723089 /home/mang/watch
try it!

Real-time database or non real-time database

I know the scheduling mechanism in Oracle database is somewhat like the Linux OS which is not real-time. Does Oracle provide real-time database which has some real-time scheduling guaranteeing each user transaction to meet with a deadline ? Thx a lot.

The Berkley DB that Oracle owns has been ported to QNX which is a real-time operating system.
http://www.oracle.com/technology/documentation/berkeley-db/db/ref/build_unix/qnx.html
Why, out of curiosity, are you looking into Oracle for a real-time system? That implies that you're running a real-time operating system on your servers, which is certainly unusual. I've heard of some ports of 9i to real-time operating systems, but that would certainly be unusual.

Oracle Report Builder Bugs

If the JSP file generated by Report Builder contains the statement,
<systemParameter name="DESTYPE" initialValue="Screen" display="yes"/>
you will receive the following error message when you try to run the report in Web Layout:
javax.servlet.jsp.JspException: REP-56092: No class defined for destination type Screen
I found the only solution to be to remove the offending statement, or set its display parameter to no. (The statement can be found in the JSP file under the <data> tag.)
This statement displays the Runtime Parameter Form dialog which is intended only for Paper Layouts. Seems as if Report Builder is reading a Paper Layout statement from the JSP file when it is executing a Web Layout command.
Another minor problem occurs when you open a report and attempt to display it in Web Layout before connecting to the database. When the Connect dialog appears, the mouse pointer remains as an hour glass.
The Report Builder came packaged with Oracle Developer Suite 10g, but the Report Builder's Help About shows version 9.0.4.2.0. However, I noticed that other copies of Oracle Developer Suite 10g came packaged with Report Builder version 10g. I can't say whether the above problems apply to these later versions of Oracle Builder or not.

Hi,
There's a dedicated forum for Oracle Reports and I would suggest you to post your questions there to get answered by those who are experienced in Oracle Reports.
I did work with Oracle Reports a long time ago, so as I remember, you have to create a link between colb and colc fields. When colb is null then this link will pull over colc and print it in place of colb.
Hope this helps.

Export journalized data in real time

Hello,
I must pull journalized data in real time out of Oracle DB source.
my package has ODIWaiForData operator and interface which triggers only in case of Journalized Data in my source table. Interface loads data to target Oracle table in real time and it works.
Is it possible to send Journalized Data out of Oracle database in real time? Maybe some insert/update statements within sql file, csv file or through ODIOSCommand operator somehow?
Regards

Hi,
did you already see about Logminer?

Not able to run Real Time Report(Live report)

Hi all,
I am working on a report which need to be run on real time, i am facing difficulty while running it at my end(India),
getting error as View Display Error whereas my counterpart in United States running at her end getting the result easly,
server is located at United States,we share the same internet speed,I tried different means by putting appropriate filter
in order to reduce the data size but still couldnt see any result. Can anyone please suggest me what is the issue
and what need to be done in order to get the results for real time report faster at my end.
Thanks for help.

A couple of suggestions.
First, make sure you are reproducing the report conditions as well as the user access settings. Different user access can make a big difference in report performance.
Second, enter an SR with Oracle support. They may be able to help troubleshoot connection issues.
When we see dramatically different response times in different locations, this usuallly means a network issue. It may not be in your corporate network, but somewhere between you and the data center.

Oracle SGA Real Time Consumption Information(9i,10g and 11g)

Hello,
I need to prepare a comparative analysis report of SGA for an Oracle Production Instance
The analysis would show the pre-allocated memory to SGA components v/s real time consumption of memory by these SGA components. I need to do this for each of following components.
SGA itself
Fixed Size
Variable Size
Database Buffers
Redo Buffers
The pre-allocated memory to above SGA components can be obtained by querying v$sga. But from where do I get its real time(current) memory conusmption in Oracle Production environment.
In addition to above, i need the same information (pre-allocated and real time consumption) for following.
Keep buffer cache
Recycle buffer cache
Specific block size caches
Shared pool
Large pool
Java pool
streams pool
Which tables do I need to consider in order to derive 1)pre-allocated memory and 2)real time consumption for above mentioned SGA components
Please advice.
Thank you for your time in reading this post.
Thanks,
Ruchir

Hi,
Have a look at v$sgastat. Also, use statspack in 9i and AWR reports on 10g. Also, the size of the caches won't grow unless they are used. The parameters you have specified within the parameter file, like sga_target (10g onwards) and possibly the other pools if you have specified them, will show you what the caches can grow to.
For example, you could just log onto the DB and do show parameter sga_ or shared_pool and you will seee values for these. Also, it depends whether you are running in automatic memory management mode - where the sga_target parameter is set - or manual. 9i will be manual, but 10g could be auto. In manual case, 9i, check out the parameters individually.
Also, read the docs about the parameters shown and you will see what it says abotu them. There will be lots in the docs about performance tuning and monitoring of the instance. You might even learn some other interesting facts while reading through the docs...
Hope this helps,
Rob

Report Queue: Can we monitor in real time?

Can we monitor the Reports Queue ( in real time) to view cache hits and cache
misses of specific reports?

hello,
there is the RW_SERVER_QUEUE database table. in order to enable the population of this table, you have to run a script and add the REPOSITORYCONN parameter to your server configuration file. there are no specific informations about cache-hits/-misses in the RW_SERVER_QUEUE in 6i, though.
