Real time database, Logger, ICM version 8

Dear;
Currently I am checking the table t_Agent_Real_Time and the values are zeros, so I beleive that maybe the writing to the real time database is disabled. In ICM version 8, where I can enable or disable the writing to real time database at the logger from the Registry (because I forgot this)?
Regards
Bilal

Dears;
It is resolved.
I just corrected the hostname for the HDS server that I have to place it in the Distributor settings at the CUCM PG in the Configuration Manager. It was keep having the old hostname that came from the migration tool.
Thanks
Regards
Bilal

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.

CFP Real Time database query

I want to do a fairly simple thing. I want my cFP to read in data, and send it to a MySQL database on a server. The reading in of the data is easy. The hard part is getting it to the database.
The attached .vi works fine when running on my Windows PC. When I try to download it to the cFP, it aborts and I get the message "Failed to download DB Tools Open Schema.vi". Now I know the cFP probably doesn't have the ODBC drivers to make this .vi work on the cFP like it does on my PC, but I was hoping that during the download, a translation would take place that would make it work. It doesn't.
Could someone take a look at the .vi and make some suggestions on how I could get MySQL queries to work on my Compact FieldPoint?
Thanks for your help; this is a make-or-break deal for the project I am working on. Even if you don't know the answer, suggestions are appreciated!

Ryan,
LAMP just stands for Linux-Apache-MySQL-PHP, and has nothing to do with Labview. It is a popular configuration for non-corporate web/database servers because all four components are free! These are server applications, so the machine never 'logs in' to be able to run Labview .exes. That's why I'm introducing a PC inbetween.
If I discover a way to run .exe as a server application, than I may revisit the system configuration.

Unable to install labview real-time

I just successfully installed labview v8.0 on a pc and this is my first time to ever use this application. I was trying to install labview real-time v7.1 for my cRIO. Unfortunately, it failed to install. I received an error message saying that I needed to have LabView 7.1 prior to the installation. LabView 8.0 is working great and I dont understand why does LV real-time wants an older version.
Do I have to uninstall LabView v8.0 and order an older version to get labview v7.1 to get running?
Any insights for a newbie will be greatful.
Thanks

What do you mean by "I was trying to install
labview real-time v7.1 for my cRIO"? It is not clear if you got
the error when installing that piece of software in the cRIO RT
controller or when you were installing the software on your PC.
Nonetheless, if your intention is to use LabVIEW 8.0, then there is no
reason why you need to install anything that has to do with LV 7.1
(such as cRIO RT support for LV 7.1 on your PC or LV RT -real-time- on
the controller). In your case, it seems to be ok to ignore errors
related to LV 7.1; it could have been that the computer you are
installing NI software on had an older version of LV that was not
properly uninstalled.
BTW, the installers should be smart enough to install the right
versions you will need given you install LV 8.0 first. To ensure all
needed pieces are installed, make sure you run the installers in this
order: LabVIEW first, followed by LV RT and/or LV FPGA, and NI-RIO last.
Hope this helps.

RAC with real time knowledge

Hi, I'm interested in learning RAC and dataguard with real time knowledge......... please help me finding some training institution or peoples with real time knowledge
Thanks

The term "+real-time+" has a very specific meaning in Information Technology. See http://en.wikipedia.org/wiki/Real-time_computing for the basic details.
Oracle RAC is not a real-time database.. and nor does the "real-time knowledge" make much sense IMO...
Always difficult to get to grips with the nuances of the English language where it is your 2nd or even 3rd language. But it is important that we speak the same language and understand the same terms and concepts, in Information Technology.

Error -1074384569; NI-XNET: (Hex 0xBFF63147) The database information on the real-time system has been created with an older NI-XNET version. This version is no longer supported. To correct this error, re-deploy your database to the real-time system.

Hello
I have a VeriStand-Project (VSP) created with my Laptop-Host (LTH) which works with my PXI, while
deploying it from my LTH. Then I have installed the whole NI enviroment for PXI and VeriStand use on a
industrial PC (iPC). I have tried to deploy my VSP from the iPC to the PXI but the following error
message arose on my iPC:
The VeriStand Gateway encountered an error while deploying the System Definition file.

The software versions of the NI products (MAX/My System/Software) between my LTH and the iPC are
almost the same. The only differences are:
1. LabView Run-Time 2009 SP1 (64-bit); is installed on LTH but missing on iPC. The iPC has a 32-bit system.
2. LabView Run-Time 2012 f3; is installed on LTH but missing on iPC.
3. NI-DAQmx ADE Support 9.3.5; something strage on the LTH, because normally I am using NI-DAQmx 9.5.5 and all other DAQmx products on my LTH are 9.5.5. That means NI-DAQmx Device Driver 9.5.5 and NI-DAQmx Configuration 9.5.5.. On the iPC side all three products are 9.5.5.. That means NI-DAQmx ADE Support 9.5.5, NI-DAQmx Device Driver 9.5.5 and NI-DAQmx Configuration 9.5.5..
4. Traditional NI-DAQ 7.4.4; The iPC has this SW installed. On the LTH this SW is missing.
In order to fix this problem I have formatted my PXI and I have installed the following SW from the iPC:
1. LabVIEW Real-Time 11.0.1
2. NI-488.2 RT 3.0.0
3. NI_CAN 2.7.3
Unfortunately the above stated problem still arose.
What can I do to fix this problem?
I found a hint on http://www.labviewforum.de/Thread-XNET-CAN-die-ersten-Gehversuche.
There it is written to deploy the dbc file againt.
If this is a good hint, so how do I deploy a dbc file?
I would feel very pleased if somebody could help me! :-)
Best regards
Lukas Nowak

Hi Lukas,
I think the problem is caused by differenet drivers for the CAN communication.
NI provides two driver for CAN: NI-CAN and NI-XNET.
NI-CAN is the outdated driver which is not longer used by new hardware. NI replaced the NI-CAN driver with NI-XNET some years ago, which supports CAN, LIN and the FLEXRAY communication protocol.
You wrote:

NI CAN is the outdated driver. I think that you should try to install NI-XNET instead of NI-CAN on your PXI-System, to get rid of the error message.

How can I generate a real-time highchart from my database data?

I have looked several links; however, I couldn't find a working demo showing how to implement a highchart using data from a database.
Objective: I want to generate a real time highchart line graph getting data from my database. What I want is very similar to the
HighChart Demo which provides a real-time highchart with randomly generated values. It is also similar by X-axis and Y-axis, for I want my x-axis to be "Time" (I have a DateTime column in my database) and y-axis to be an integer (I have
a variable for that as well in my database).
Please I need help in sending the model data to my razor view.
Note that I am already using SignalR to display a realtime table. I also want to know if it can be used to automatically update the highchart as well.
Below is the code snippet of my script in the view. I have used the code provided in
HighChart Demo link for generating the highchart. Please tell me where should I apply the changes on my code.

Database Aplication Tables Reconciliation in real time

Hi.
Is there a way to get database aplication tables trusted reconciliation in real time?
I mean, If I add/update a row to a table in the trusted source, some type of agent calls an API in OIM which gets the added/updated row (and creates the user)
Thank You.

DBAT Connector will not fulfil your requirement.
Please see the below link. It may help you in developing what you want. You can call OIM Recon APIs through DB Trigger

Want to real time copy database

hello
i use oracle 10g release 2 with windows server 2003 standart edition(who don't work with cluster)
i a beginner with oracle and i want just know if i can do a real time hot copy of database to another database(other pc) without use oracle cluster.
i want only that my database copy herself real time (or with a light late, only few minutes) into another database everytime she is update with request sql.
Someone could help me???
thx
laurent

streams is good but requires setting up a distributed environment.
My recommendation is:
Run the database in archivelog mode.
Backup using rman, online little load on the database.
Restore and recover to the destination server, then copy the last archive logs over and apply them.
Advantage of this is: nearly no load on the primary database.
technically it is more or less the same as creating a standby database. But you do not need to shutdown your primary database to produce the initial copy.

Real-time apply cascaded logical standby database

Hi
I have a primary database orcl
Pysical standby database orcl_std
Cascaded logical standby database orcl_tri which receives archivelogs from orcl_std
Real time apply is enabled both in orcl_std (physical standby) and orcl_tri (logical standby)
When I create a table in primary orcl, I am unable to see it on orcl_tri (Although real time apply is enabled)
However, when I switch log in primary, I can see the new table on orcl_tri.
My question is, why realtime apply is not working in my scenerio ?

Hi mseberg,
Thanks for your reply.
There is no load or network issue as I`ve just created these databases for the experiement.
I have the same output from standby and primary databases.

Can any one give me the SQL to identifiy that my physical standby database is in real time applying redo logs?
Its urgen please....
Thanks.

You could just look at the alert log. Look for "Recovery of Online Redo Log"
Or you could select from v$standby_apply_snapshot to see if the standby is up-to-date.
select thread#, to_char(snapshot_time,'dd-mon-yyyy:hh24:mi'),
to_char(applied_time,'dd-mon-yyyy:hh24:mi'),
to_char(newest_time,'dd-mon-yyyy:hh24:mi') from V$STANDBY_APPLY_SNAPSHOT;

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??
-Panky

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.

Can oracle database interact with sysbase database in real-time?

There are two database,one is oracle,one is sysbase,sysbase is produce database.My program only can visit oracle database,and can't directly visit sysbase database.My question is whether there is a directly link from oracle database to sysbase database,when I visit oracle,oracle database can interact with sysbase database through this link real time? How to realize above function? Please give plan for it.
Thanks in advance!
Best regards,
Edward

Yes there is. You have to create heterogeneous connection between these two databases
Take a look at below links:

TDMS database and treat its values as real time data.

Hi,
I'm newbie in using labview. Actually I wanna import data from TDMS database and treat it as real time data. Although I have done the first part which is importing the data inside the program by reading TDMS and selecting channels and groups, I couldn't find way for second part which is treating data as real time one. I tried Build Waveform, but it didnt work. Would you please help me to solve this problem ? I appreciate your helps.

reza_amin,
I don't understand your word "build waveform". If you write waveform data to a tdms file, you will read waveform data directly from the tdms file.
If you are using LabVIEW 2012 (download from http://www.ni.com/trylabview), you could find a tdms example VI in "C:\Program Files\National Instruments\LabVIEW 2012\examples\file\plat-tdms.llb\TDMS - Concurrent File Access.vi". This example VI demonstrates how to write Sine Waveform into a tdms file and read the Sine Waveform from the tdms file.
Hope this helps and enjoy your LabVIEW journey. :-)

Bo Xie

Is there an 8.2 version of the local executeable for real-time?

Hi all.
Been working on some new software for LabVIEW real-time, using 8.2. Our users like the way things were built around here circa v7.1 when we would build an executeable on the local PC. When we ran it, it brought up the target selection dialog and would download and then run the application to the real-time station, displaying the user interface in the application instance on the local PC.
Is there an equivalent to this build type in 8.2, or is it all remote panels nowadays? Many of these old-school applications are being ported over to 8.2 so a rewrite to split the application into real-time and user display executeables would be a bit much. I'm also hoping to avoid needing additional remote panel licenses in the frequent case where they have more than 5 windows open at once.
Thanks,
Dan

Hi Dan,
Thank you for contacting National Instruments. In the more recent versions of LabVIEW, 8.0 to 8.5, this process is integrated with the project. Therefore, there isn't an equivalent build type to that you have described in LabVIEW 7.1. In this format a target VI along with a host VI is commonly used in Real-Time applications. The host VI is not necessary, however if you desire to have a user display/interface, or significant data storage this should be done on a host VI to maintain determinism.
If you do want to have a basic Front Panel on the Real-Time target, this can be accessed via Remote Front Panels. However, from a built executable only one instance of this can be opened at a time. Therefore, if you have a need to view this Front Panel from multiple points at a time, you can do this if the target VI is not a built executable, but merely run manually from the host computer.
I hope this helps. Let me know if you have related questions or need additional clarification. Have a great day!
