Database triggers VS Front end triggers

Hi All,
We have online ticket reservation application developed using oracle forms 6i and Oracle 8i database in Client server multiuser environment.
for example we have scenario like this.. AFTER INSERTING into TABLE A,
we need to UPDATE status column in TABLE B, for achieve this which is better option
To write database trigger on A,
or To write a POST INSERT trigger in the form designed uisng TABLE A.
basically the the dataentry is done through Front end only.
we are going to have upto 20 triggers of this scenario in the entire database on diffrent tables.
which is best practice? in terms of performance.
And we want to have DAY END, DAY CLOSE system, so that once we close DAY, no one allowed to insert data into few tables, for this can we use database triggers or front end check.
Thanks in advance

There isn't a confusion here between "application" meaning front-end tool, and "application" meaning "whatever layer contains your business logic" is there? I didn't mean to suggest that i thought it a good idea that business logic be implemented outside of the database, just that it ought to all be in one layer -- my own choice would be db packages, but if someone were commited to putting business logic outside of the db, then that would be the place for all the code.

Lync 2013 updating databases after updating Front End servers

We have a front-end server pool consisting of 3 Lync 2013 servers and a back end of 2 SQL servers using SQL mirroring. All servers are Windows 2008 R2.
Following the instructions in
http://support2.microsoft.com/kb/2809243 , I verified that the servers were all ready for updates, then I ran the
Stop-CsWindowsService -Graceful cmdlet to stop the Lync services on the first FE server, then I ran LyncServerUpdateInstaller.exe to install the updates. After the updates were installed, I restarted the server, waited for Lync services
to all start, then repeated the process on the next 2 servers in turn. This was all successful.
I am now looking at step 2 in this document, applying the back-end database updates, and I have a problem and some questions. The problem is that all the databases had the principal copy on the mirrored SQL server. I ran the recommended Invoke-CsDatabaseFailover
-NewPrincipal Primary cmdlet repeatedly, using all the database types I could find, but I still have two databases (database names
xds and lis) on the mirrored server. Since the cmdlet requires a database type, what type of databases are the xds and the lis databases?
Once I get that done, I an still unsure of exactly what to run to update the databases. The KB article states to run Install-CsDatabase -ConfiguredDatabases -SqlServerFqdn FEBE.FQDN -Verbose .  Do I type this in exactly
as stated, or is FEBE.FQDN a variable for our SQL server or some other entity in our environment? If I do use the actual SQL Server name in that, do I run it twice, using the name of the mirrored SQL server the second time?
Thank you very much for your help.

Hi Logan Burt,
Central Management store database files
Data file or log purpose
                Xds.ldf
Transaction log file for the Central Management store
                Xds.mdf
Maintains the configuration of the current Lync Server 2013 topology, as defined and published by Topology Builder
                Lis.mdf
Location Information service data file
                Lis.ldf
Transaction log for the Location Information service data file
And you could verify if Lync Server 2013 database updates have completed successfully.

database. I am integrating the flex with spring and hibernate

link.All the documents are stored in database.So for example if a
user clicks on a link on flex frontend screen it needs to open a
pdf file whihc is stored in database.So can you please post me the
connection details as how flex calls java and inturn java calls
backend to get the document from database.I am using flex,Spring

Let's start with the basics:
Do you already have an understanding of how you'd perform
these steps if
Flex were not involved (i.e. some sort of static or dynamic
html page in the
browser)?

MYSQL as front-end to MS Access via LabView

Hello members,
There is a part in my project where a program writes to a MS Access database (DB). I want to be able to take this Access DB and use it to update a MySQL DB using LabView. I have already created the DB in MySQL with exactly the same structure as the DB in MS Access. Basically, what I am trying to do is that every time the MS Access DB is updated I want to be able to post-run a VI to update the MySQL DB. So MySQL DB is my front-end for MS Access. I have the data connectivity package and I have tried couple things but in vain. I can insert data into MySQLDB but I have not been able to update a specific existing column in a specific existing table. I have searched online too for possible ways to do it and most discussions/ solutions are for MS Access to be the front-end for MySQL (I need the opposite to be working). Some other discussions were for migrating MS Access to MySQL, but it is not what we are trying to do. The MS Access DB will always be there. I do have all permissions to read/write to both DB.
I will appreciate any suggestions or input you may be able to provide or if there is a better/ efficient way to do it.

Based on your description I don't see how either database is a "front-end" to either one. It sounds to me like you are updating the two databases in parallel. For it to be a "front-end" MySQL would need to update the Access database directly, not LabVIEW. So LabVIEW would know nothing about the Access database. This means all the work would be inside of MySQL (such as with triggers on table updates and insertions, which I'm not sure if MySQL even has).
I don't understand your statement about being unable to update a specific existing column in a specific existing table. What exactly are you trying? What VIs are you using? What are your inputs? Can you post your code and a quick overview of your schema?

To avoid writing database code in the front end

Hello,
I am working on a database application using 10g database as backend and dotnet as front end. I wish to execute only oracle stored procedure for all the select (to avoid hard parse and use of bind variable), DDL and DML operations; just to avoid writing database code in the front end. Can anyone please give me a little examples of :
1.Select query's output to be return as resultset by stored procedure.
2.DML example by stored procedure.
3.Any DDL example by stored procedure.
using scott.emp, so that i would just call the stored procedure, rather than giving select,DML and/or DDL commands in the front end. Even though i have read in the documentation, but a clear cut examples will help me to get into clear concept as well.
Thanks & Regards

Can i use java only for database transaction with vb as a front end

Hello All.
I am sorry,i don't know whether this location is the correct location to post my question or not
I have developed one application using complete vb only. That is completly desktop appliation and not suitable for centralized database. Is there any facility to keep my front end as same (vb application) and for the database transaction can i use jdbc? Is there any possibility to do that like View is vb based application and the database connectivity is only jdbc
If my thought is wrongplease execuse me.
thanks in advance

Front End to Oracle Database - Advice Needed

Hi
My company has recently purchased an Oracle Database. Are there any advantages in creating the front end in Oracle as opposed to writing the front end in Java.
I am interested to know if one method is preferred over the other. I was planning on writing it entirely in Java.
Any help or advice would be appreciated.
Thanks
Kelly

Removing admin password form Access 2003 database front end and back end

We have a legacy database that has been passed down from the original creator, who is no longer with the organization. It was created in Access 2003. It has a front end and a back end. The original admin password can not be located and we are in the process
of upgrading this application to 2010. Is there a way to remove that password so we can make changes to the original files?

Hi,
What password are you talking about, the one created with the workgroup manager? That will be difficult since 2010 doesn't have the workgroup manager anymore. You can still use the database in the 2010 environment but you can't make any changes to the original
database without the password.

Error running utility "Maintain database triggers to circumvent mut tab"

Hi,
I succesfully runned the utility to create the table package, but when running the database triggers utility I receive:
Message
Activity aborted with ORACLE internal errors.
-6502 ORA-06502: PL/SQL: numeric or value error: number precision too large
I tried on a smaller table and that one is running ok. Is there a maximum on e.g. columns to have the utility work proper?
Or is there perhaps the column_name what can be the problem?
Regards

Jessica,
It sounds like bug 897808 (HSDUTL). It should be fixed in Headstart 2.1.2 patch 11. Are you sure you installed this? Note that installing patch 12 doesn't install patch 11.
If this is indeed the problem you are running into, the offending statement is located in the package HSU_CCMR (revision 2.1.0.2). Within the procedure add_block the variable l_number_of_lines is declared as a number(2), this should be changed to a number(3).
Kind Regards,
Peter
