Designing opinions about a network database application

Hi all,
I want to develop a small application with Java that will manage data. The size of the data is small. I do not need a client server database (ex.Oracle or Sql server). I also want to make a version of these application to work as desktop application and another version as an applet (maybe with few abilities than the first). My problem is which technology i will select to manage data for my my application ? I wonder if it is a good choice to work with MS Access via JDBC or with simple files. I have never work with XML, Is this Technology a solution for my promblem. I suppose that the promblem is the connection of the java applet with the data center. Have someone any great idea?
Thank you for advance Kostas

will manage data. Relational data? flat data? numerical? statistical? If you don't think you'd ever use a RDBMS like Oracle or MS SQL Server, then why be considering JDBC?
You may need to define your parameters a little better.

Book recommendation for database applications

I'm a LabView newbie. My primary work will be file and data manipulation using the database connectivity toolset. Are there any books available to help with database applications?
Thanks

Hello Paul,
I cannot offer much recommendation on books about development of database
applications from the database end (though user ratings through places like
Amazon have usually treated me right). If you are interested in
learning more about how the Database Toolkit for LabVIEW can be used, the Database Connectivity Toolkit
Manual is a great (and comprehensive) resource.
Hope this helps!

Questions about database application tables connector

Hi all,
I need to manage with OIM several databases (each one with its custom tables).
Also, one of them will be my trusted target on the initial load of users. The structure of our tables is not similar to the included in the example.
The documentation explains how the OraAppX.xml could be modified but it doesn't speak about relations with "DBTable_nonTrusted.xml" and/or "DBTable_trusted.xml" For example, if I don't have a column called USR_COMM_LANG, could I replace this column name for another that I have in my database ? And what about the references on the "DBTable_nonTrusted.xml" file. Connector doc doesn't explain how references to that field (USR_COMM_LANG---xel_usr_comm_lang) are managed by the connector and if the normal working of the connector could be affected if the name of a variable is changed in the xml conf file.
It could be that adapters of this connector were hardcoded with the referece to xel_usr_comm_lang (???) .
The connector documentation includes a section titled "Adding Custom Database Columns for Provisioning and Reconciliation". The first impression reading this document is that it is possible to extend the predefined table rather than create and define a new structure of table.
Has anyone rebuilt the "DBTable_nonTrusted.xml", "DBTable_trusted.xml" and "OraAppX.xml" files changing all default variables in order to manage a customized table? .
Many thanks in advance,
Claudia

Hi Claudia,
1) Yes, you must replace the column names in the "column" tag on your XML file for the column names that you have in your database tables. Also, remember that you need to configure the other parameters (like data_type, data_typ_size, etc) according to your database table.
2) The "xel_data_source" parameter is the attribute name that will be recognized by the OIM and they can be mapped to a form field (UD_DBAPP_XXXX) in your process definition in OIM Design Console.
3) You can customize your Database Application Tables connector for provisioning as you wish, but some issues exists. In the Known Issues section of the documentation you can see that this connector doesn't work for more than two tables.
4) To customize your Database Application Tables for Trusted Recon, there are other restrictions because OIM users have some required fields that must be filled to create a user successfully.
Hope that helps, and please let me know if you have more questions.
Regards.

Web database application design examples wanted

Hi! I�ve written a couple of smaller web database applications in Java but I�m not completely satisfied with my design, especially where and how to put the database code. Now I�m looking for small open source examples of good design of web database applications in Java. I would appreciate if you could direct me to a good example application, preferably easy to understand. Also feel free to mention any other resource that you think I should look at. At the moment I don�t have the time to read a complete book but I plan to do this later � so book recommendations for professional Java developer are also very welcome.
Summary of recommendations I would like to get:
1) Java web database application with good design
2) Design book for professional Java developers
3) Any other design related resource
Thanks!

Simple java/mysql database application question about triggers

I am planning a new database application using java and mysql. I may want to use some triggers to automatically update the tables when a change is made. my question is this: If I write the trigger, and I use Java to modify the database, will java automatically pause and let the trigger finish doing its task before it continues? what if it writes more to the table before the trigger is finished modifying the table? how do I get java to pause and let the trigger finish?
thanks for your response

It doesn't have anything to do with java at that point.
When you execute, for example, an insert statement, then the database executes that statement. The database (not java, not the driver) decides with that statement is complete. Control returns to java when the database decides that execution is complete.
And except for tricks that one might do (or attempt to do) via SQL or triggers then when the statement execution finishes then everthing has completed running.

Interested in finding out about using LabView in Networking Testing applications.

Networking Testing applications, such as:
- General Ethernet and POS testing
- BERT
- RFC2544 back to back, Frame loss, Throughput
- RFC2285
- IP Multicast
- QoS
- Load Balancing
- Wireless IP
- BGP
- Other Networking testing

LV provides a lot of tools which make VIs remotely communicate and control through net easily,such as VI server ,datasocket,tcp/ip,opc etc.I do not have much experiences in the environment you decribed,but in the internet and general ethernet programming with LV is very easy and interesting.

Advices for database application

hello,
We looked for exising solution to manage mesuremens and devices park without finding one that fit
maybe one of you know/use a good one !
so we are thinking about creating our own
in few month i will have to develop a database application with postgre, this database will be used
to store devices mesurements, accuracy, drift , create alerts regarding calibration date,
printing calibration , verification certificates also stickers ....
Creating the dabase sould be ok, my question is more regarding the langage to use to create interfaces
things to know:
- that i will not have any specifications or so few, this will be incrementals propositions
- I ' now quite comfortable with labview
- php it surely the best way but i don't know any about it nether html ,css ...
- i could have a one week php course
- php is distributed application
- how to manage network shutdown with labview or php
- i will need to access an existing database an creating link with the new one
- about 10 users can use the application
- i don't have conection with web developper in my work circle
project is interesting , my anxiety with php could be to re write again and again , each time i will progress on this language
with labview i'm not sure that is the best way to create this type of application and to be forced a day or another to switch to php
If any advices don't hesitate

Don't forget to valid a good answer / pensez à valider une réponse correcte

I have been doing something like this for a while. I really do not like php but in all fairness I have not looked at it for several years. What I use is Python on the server through the Django web application framework running on Apache. It is very simple and easy to use.
The LabVIEW code writes data through http POST requests and the server inserts this data into the database. I do not use the Django object relational mapper. Instead I build the SQL inserts manually. I do this mostly because the database already exists and I just find it more natural.
I also do not make use of the Django template engine. The server returns XML to LabVIEW which looks something like this:
<Response>
<Error>
<Cluster>
   <Name>error in (no error)</Name>
   <NumElts>3</NumElts>
   <Boolean>
    <Name>status</Name>
    <Val>0</Val>
   </Boolean>
   <I32>
    <Name>code</Name>
    <Val>0</Val>
   </I32>
   <String>
    <Name>source</Name>
    <Val></Val>
   </String>
</Cluster>
</Error>
<Data>
<Cluster>
   <Name>Hello from server</Name>
   <NumElts>3</NumElts>
   <String>
    <Name>String</Name>
    <Val>Hello</Val>
   </String>
   <Boolean>
    <Name>Boolean</Name>
    <Val>1</Val>
   </Boolean>
   <DBL>
    <Name>Numeric</Name>
    <Val>42.00000000000000</Val>
   </DBL>
</Cluster>
</Data>
</Response>
Can you see what I am doing? I am returning an error and a cluster which can be unflattened using Unflatten From XML. I can set LabVIEW errors from Python for things like a request without the required parameters or whatever. I have a Python class that builds the XML Response which contains exactly two children - Error and Data. It has methods including createCluster, addLVObject, createLVArray, insertLVArrayElement, setError, etc. Finally it has a getXMLResponse method which returns the above XML string.
I return that using the Django HTTPResponse object and get at the data in LabVIEW like this
The returned cluster can be as complex as you want such as cluster of cluster of array of cluster. It always returns a cluster so if you want the server to return say an array then you will get a cluster containing an array that you simply unbundle. It supports strings, all the numeric representations, paths, visa resources, boolean and something i am forgetting at the moment.
Also my URL configuration is very simple since I only POST and do not send GET requests. This means I can map the URL directly to the Django view method of the same name. I get the parameters with request.POST.get('Parameter Name')
I know for a fact that you can do all of this with php but I just prefer Python. If none of the above makes sense then come back to it after you read about Django.
Good choice if it was a choice to use PostgreSQL or a stroke of good luck if it was not a choice. This is what I use and it has been rock solid for years. I really want to upgrade because the NOTIFY now supports data payloads. I have had to do some crazy things to get around the fact that the older versions do not support this.
I am thinking seriously about putting together a tutorial on this whole thing.

OIM Database Applications Table fails to connect via GTC - Weblogic, Linux

Environment:
OIM - 9100 (public download)
Red Hat Linux
XLADM Oracle 10g
Weblogic 8.1 SP6 - no cluster
I have installed the Database Application Connector and am trying to configure it via the Generic Technology Connector, but it keeps failing to connect. I know those parameters are correct and have validated via sqlplus \ SQLDeveloper. Also its the exact same database (not SID) that is hosting XLADM as well, so I know it can find the machine and such. I had another previous OIM on JBoss install locally on my Windows workstation that worked fine too. I can see in the log that the DBProvisioningTransportProvider is getting the props fine and then blows up when trying to connect. I have tried even updating the ojdb14.jar drivers in XELLERATE_HOME/ext and that doesn't matter. I'm sure it's something simple, environment related, or a bug. Any help is appreciated.

Networked Database speed issue...

I apologize... I am kind of new to programming and have a limited scope of understanding when it comes to databases and sql queries. I was given the task of creating an application to perform a sorting algorithm and implemented it using LabVIEW 2013, the database toolkit, and a MS Access 2007 database. The application I wrote worked great when it was first deployed and now that it has been operational for about 2 months, it has slowed significantly. I did some testing and I think I have isolated the latency to network communication issues.
I believe it is network speed/traffic related because I copied the database locally and sorting was only about 2s - the networked copy takes about 14s!!! Also, the number of users had no impact on this number either - I created a copy of the database, renamed it, saved it to the same folder, pointed my application to that file instead and it was still 14s... The only noticeable improvement was using a local copy, which will not work for this scenario.
I spoke to a few people about it and someone suggested changing the cursor location from server based to client based (http://msdn.microsoft.com/en-us/library/windows/desktop/ms676564(v=vs.85).aspx). Only thing is, I cannot figure out which LabVIEW is using or how to change it... Is it changeable? If not, do you have any other suggestions for speeding it up? It is unlikely I will get much support from our IT department, so any improvement suggestions will have to be recommendations for change to my application.

I suppose I should have been more clear when I said sort...lol. The application is used to find a PO for a particular device (sorting to a PO). There is only one sort operation (a->z) performed in any of my sql queries (see below)
I was concerned about using the database as well - mostly because I'm not as experienced using them... The original implementation of the application used text files and flags to prevent data collisions, but we have about 10 people sorting at one time and it was creating a huge lag time.
The network location of the database (we believe) is probably what is causing most of the issue. Our IT dept keeps things very locked down and there weren't many choices for implementation methods. I was forced to use a shared folder on the network to store the database and this shared folder is accessible to everyone in our facility. Be believe the general traffic to this server is probably most of the issue we are having.
when the version 2 sort tool was deployed (the one using the database instead of text files) it took just a few seconds to return a result - on the order of 3-5s. There are now over 150,000 entries in the database, so I'm sure that too is contributing to the lag.
The database has several tables:
(1) Log Table: used strictly for logging the device sort data,
(2) Liquidation Table: lists all of the possible sort locations and the device requirements for each PO,
(3) Activity Log - used for capturing devices which shouldn't be sorted or other device condition based exceptions,
(4) Allocation table - for each model it lists whether the device should be sorted to a PO based on the priority of the PO or an allocation percentage, and
(5) Requirements table - only 3 entries. Used to control specific behavior of the sort.
I have several SQL queries in the code that hit this database...
1. Check the requirements table. The flags reside in the table to (1) stop the sorters from being able to sort devices temporarily and (2) a flag to force all devices to be cleared and/or graded before they can be sorted.
SELECT Requirements.Requirement, Requirements.Enable FROM Requirements
WHERE (((Requirements.[Start])<Now()) AND ((Requirements.[End])>Now()));
2. Check the log to see if the device was already sorted - if it is, it flags that log entry so it is not counted against a PO and can be resorted.
SELECT ID FROM LQD_Log
WHERE PO_ID > -2 AND ITEM_ID ='[ITEM ID]'
If not null, a case statement updates the PO_ID for that log entry to a value that will not count against any open POs.
3. The next query is a little more complicated. Depending on the device condition, several case statements build the SQL query string to find a PO the device can be sorted to. Since there could be multiple POs returned, I have it return the POs (at most 5 or so) sorted by priority. (there are 13 elements for each PO returned).
4. The next query checks the allocation table to see if the that model is to be sorted based on priority of the PO or by an allocation percentage.
SELECT Percent FROM Allocation_Table
WHERE CNN ='[COLOR NEUTRAL NAME OF DEVICE]'
A PO is selected in my LabVIEW code based on the POs returned and the allocation method.
The PO (Sort location) is displayed to the user. they scan the sort location and then I write the information to the log in the database - Pertinent device characteristics related to the sort decision, PO Information, user information and scanned location (21 elements).
There is very little which can be done about the location of the file... it has to be in a shared location, and it has to be able to support multiple user access. One of the programmers here recommended using an Access database for this reason and many others. I could possibly lock it down with flags again, but I'm afraid that would only contribute to the problem - I did test a copy of the database to the same network location and I saw the same types of delays, so I really do not believe it is related to multiple users accessing the file.

Design question about instant download a patch

Hi All,
Here is a design question for you:
Background:
The application we built is being upgraded from time to time and we send it to our users.
our users use it on a network so there is only one file to upgrade (and being done by the sys admin)
We send them a �patch�; actually, it�s a new version of the application they place it in the relevant folder and continue to work with a new version.
Problems:
1. We send them the patch via email - sometimes it takes a while until they read their email and at they are using an �old version of the system�.
2. Some of them are not computer savvy (when it�s not the sys admin) and we need to guide them as where exactly to place the file (there are 3 files)
Our (conceptual never build yet) Solution:
Build a program just like Norton antivirus (or other) that prompts the user from the task bar (next to the clock) that a new version is available and by
clicking once it will automatically download the file and store it in the correct folder.
Question:
1. Did anyone try anything like this before (or something like) who can tell me about it?
2. Do you think this kind of system will work for us?
3. Does anyone have a better solution?
Thanks
Peter

thanks, I posted it there.No, he meant that Webstart is the mechanism you should use. It supports net-based distribution and automatic centralized updates of apps. Exactly what you want.

Java WebStart is the deployment technique suited for your purposes.
The deployment will be done via a webserver running a jnlp servlet (provided).
The applications may either run offline, or check online for automatic updates.
You have several configuration options.
ArgoUML and jEdit are two open source apps delivered this way.
Your app will need to be adapted though.
And your customers need an online browser with installed jvm.

OIM11g Error GTC trusted recon using Database Application Tables 9.1.0.5.0

Hi!
I'm using OIM 11g (11.1.1.3.0) with Database Application Tables 9.1.0.5.0.
I've setup GTC trusted recon connector as follows:
1st Step: Filled required Run time parameters
2nd Step: Mapped 11 fields
- User ID
- First Name
- Last Name
- Email
- Organization
- Role
- Design Console Access
- Status
- Employee Number
When I run the task I get an error in the log.

The error is "(EMPLOYEE_NUMBER) does not exist in table USR". This field is a default OIM field. If I remove it from the mapping, the recon works OK.
I have the same error if I mapping a UDF field that the label has a white space (eg.: Cost Center).
This happens with other default OIM field:
- Hire Date
- Display Name
Any idea?
Are there any workaround for this?
Thanks,
Ariel

Hi!
I found the bug in metalink "Bug 10041190 GTC Recon Failed With new OIM UDF Attribute Map If Attribute Name Has Space"
The workaround is: Don't use UDF's with a space in the attribute name.
This issue is fixed in 11.1.1.3.2
Thanks,
Ariel

Query with the Connector Pack Database Applications Table 9.1.0

Hi,
I have configured with a connector Database Applications Table (OIM-BDSQL2005) specifically to a table, how can enable the user to log into this can be the BD SQL2005
Thank you

I had a liitle progress here. For the missing mandatory fields, once you are done the mapping during the creation of GTC, go to Design Console to add mandatory fields, such as user type which is not available in the creation process of GTC. Please see:
=> http://st-curriculum.oracle.com/obe/fmw/oim/10.1.4/oim/obe12_using_gtc_for_reconciliation/using_the_gtc.htm#t5
Now actually I have exactly the same proplem as this one:
=> Re: Creating GTC in OIM 11g (11.1.1.3.0)
=> Event Recieved
=> Data Validation Succeded

=> Creation Faild
=> Notes: ORA Error Code =>ORA-01400: cannot insert NULL into () ORA Error Stack =>ORA-06512: at DEV_OIM.OIM_SP_RECONBLKUSERCRUD", line 722
I am looking into this, will keep you posted.

OIM(11.1.1.3.0) supports connector Database Applications Table(9.1.0.5.0)?

Hi, any one has been able to do a reconciliation from an Oracle database table(as trusted source) to OIM, based on the following versions:
Database: Oracle Database 11g Release 2 (11.2.0.1.0)
Connector: Database Applications Table(9.1.0.5.0)
OIM: 11.1.1.3.0
I have similar issues as in the following post:
Re: Creating GTC in OIM 11g (11.1.1.3.0)
The basic issue is, we don't know how to map the reconciliation staging data set to OIM user data set for such reconciliation. The attributes listed in the OIM user data set are missing the following ones, which are supposed to be required:
user tyep;
employee type.
Any one can help?

Hi J brothers,
I am trying to build a 2 tier database application using java as a front end to run on a windows platform. I am not so familiar with java, what I want is to design a GUI (forms) using java which should query the back end database (MySQL or MS SQL server) and do all sort of data processing. As a beginner I dont want to use J2EE and not going for a web based application.
I need your help to get this done and any help is highly appreciated.
my email address is [email protected]
thanks a lot Jbros. bye
maatte.

Oh no! I 've made a mistake. I provoded a wrong email address. so please dont send replies to that address. the correct address is "[email protected]". I hope no body has sent to the preveous address, if so please send it to the correct address provided with this post please.
And thank you very much, linuxhippy. I am lucky because you prefferd the forum. thanx a lot. I think I better stick to the forum.
Any more help, please. I am waiting for a good solution.
