A guy made an oracle based web forms and setup oracle database in my computer 3 years before.
Now I want to make my database online.
So that I could access via my two computers.
I do not even know basic thing about oracle.
If any one could tell me how to do this?
someone told me I have to do it via live IP, dedicated server or VPS?
Could any one can give me idea from where should I start?
Should I buy a dedicated server or VPS or any other way to do this.

it's been 2 months I'm working for a new client on BI Reporting on Oracle BI Publisher within an OracleCloud CRM and HCM. to make query to OracleCloud database I have to use notepad++ and then copy/past my query in the Query textArea on BIPublisher (which is a simple text area without any syntaxe check or color), I was wondering if there are some experts who might know a way to connect SQL Developer to OracleCloud database so I can run my queries directly without copy/past on the browser.
thank you a lot
There's no direct access to the underlying Oracle Database from your SaaS subscription.
We (the SQL Developer team) are working with a few of the SaaS business owners to make SQL Developer Web available for their subscribers. This would allow you to run queries directly against your database w/o having to do the copy/paste jump you're doing today in BI Publisher.
I cannot provide guidance on when this will happen or even if your particular services will make it available.
The TL;DR answer to your question is 'No, but we are working on it'
I have deployed same application in two different computers. Now i need to merge both data from two different database into single database.
The application is developed using c# .net and uses sql express 2008.
The problem arised because i could not use the application over LAN.
So i need to merge the two database into one.
So please help me to solve the problem to merge it.
I also need to run the application over LAN but the sqlbrowser doesnot start and i have searched the internet for the answer but i haven't been lucky.
thank you, waiting for response.
The approach you want to take will depend largely on your schema, but Microsoft Sync Framework should likely be useful. It would let you define rules for resolving conflicts and merging your data.
As for accessing your data over the LAN, this post has a good overview of what it takes to enable remote access to your SQL Server Express.
I am trying to access a remote MySql database from my iPhone application. I googled, but I can't find anything that works. Can any one suggest a clear way to do this?
Since the iOS SDK does not contain any API's that can access a MySQL database, you have two options:
Implement whatever is necessary in order to talk to a MySQL database engine.
Talk to an application sitting in between your iOS application and your MySQL database.
Of the two, nbr. 2 is by far the easiest, and the normal way to do that is to set up a web service somewhere that you can talk to.
You will have to implement web service methods for whatever kinds of operations you need to perform on your MySQL database.
Exactly how to talk to that web service, and exactly how to talk to the MySQL server from your web service, those are separate questions.
We're currently using the SSO component of Oracle 10g App Server to authenticate users on our external / internet facing client "portal" (think similar to online banking)
SSO uses Oracle Internet Directory to store it's data, and we've been able to use PL/SQL and Java to access and modify the data held in OID (e.g create/drop users, change/verify passwords etc)
With the advent of 11g, Oracle appears to have "orphaned" SSO… it is available, but only as an add-on, and it appears to have been superseded by Oracle Access Manager. I'm guessing that it will have been dropped together by 12g. Plus it looks pretty difficult to install and get running correctly.
So, I'm wondering if anyone has any experience of having had the same migration problem as us? If so, what did you do?
Alternatively, does anyone have any experience of doing something similar using Oracle Access Manager? Do you think it will do what we want?
Or is there a better road to go down? Is there something else I should be considering?
Sorry for the very broad question, but it's one of those situations where a person's experience of what does + doesn’t work can make an enormous difference to us making some progress in a timely fashion. Thanks.
From my knowledge, Oracle Internet Directory (OID) is an LDAP compliant directory whereas Oracle Access Manager (OAM) is much more complex and consists of two main systems:
Identity System (users, groups,
workflows)
Access System (single/multi domain
SSO solution for Web and non-Web
based applications).
Access Manager relies on an Identity Server which is a stand-alone server process that communicates with any Directory Server (AD, OID, Sun Directory server..).
So you can use the new OAM and link it with your existing OID... to retrieve users/groups and metadata. All that you could do with OID will be doable with OAM as it brings more abstraction layers.
But in my opinion, and considering your case, directly accessing LDAP servers (OID, AD, etc) and using a light and "home made" SSO system is cheaper than relying on those big systems.... I think OAM is a usefull solution when you have lots of heterogeneous applications (web, non web, mobile, ...) and/or multiple organizations/domains with links and/or you need a very scalable approach.
I'm looking for advices and suggestions on how to synchronise data between two databases.
The first database is a SQL Server 2008 Express that run on disconnected laptops (no network or internet access). The second database (main) is a VFP 9.0 that run on a server.
When the user connect their laptop on the network, I want the synchronisation process to go through.
Other than the different database engines, I have the following items to take into account:
The tables don't necessary have the same structure
The primary keys are not the same (GUID in the SQL Server and often a combination of character fields in VFP)
Synchronisation of the tables must be done in a certain order to respect the parent-child relationships
On some insert on the SQL Server side, a new primary key must be generated and synchronised in the VFP table
A bunch of validations must be made and some feedback from the user are sometimes needed
Not all records need to be synchronised
Some records on the SQL Server need to be deleted after the syncronisation
Need to take into account deleted records from both side
Minimal modifications need to be done on the VFP database
There are probably other points I'm forgotting now, but I think you get the idea of the challenge I face. My guess right now are that I will need to build a custom synchronisation module, but I want your input before I go on in case I overlooked some options and to get some tips on how to approach this.
I looked rapidly at Microsoft Sync Framework, but with all the restrictions I have and the fact that there is no VFP client already built (AFAIK), I don't think it will be of great help.
Thanks in advance for your feedback.
Update: The laptop application is a C# WinForm application and is using SQL Server 2008 Express.
The complexity of the situation and requirements leads me to believe you need to write a Visual FoxPro application. Visual FoxPro connects to SQL Server 2008 data easily. The complexity of the code is matching the requirements and identifying the data that needs to be synched, not the syntax. Visual FoxPro strength is in the data manipulation language and the ability to connect to almost any data source (native DBFs, ODBC, ADO, and XML).
SQL Server can read VFP 9 data via the VFP 9 OLE DB driver. You could write T-SQL stored procedures to get to the VFP data. Not sure how it would recognize the laptop being connected to the network though.
Another approach is to use SQL Server XML Diffgrams. I am not an expert by any stretch of the imagination on this approach, but it would be something you can research.
Since my expertise is with Visual FoxPro I would find it way easier to go the other way though, but that is just me. You have to go with the skillset of the resources you have for the project.
VFP reads and writes SQL Server data via a connection (DSN, ConnectionString) and any technique involving SQL Passthrough (SQLConnect(), SQLExec() and SQLDisconnect()), CursorAdapters, Remote Views, or a combination of the three.
A Visual FoxPro program can also recognize Windows Events like connecting to a network. The application could be installed on each laptop and running to recognize the Windows Event. Once the event is raised the application can attempt to connect to the SQL Server database (possible it is connecting to a network without the SQL Server available or a different network).
Once connected it runs the logic to check and synchronize the databases.
Sounds like you don't have a lot of control over the application writing to the VFP 9 data on the laptop. If you do have control over the application writing to the VFP 9 database you might consider changing the app to write to a SQL Server Express instance on the laptop and then you can use SQL Server replication to manage the synchronization. Not a trivial task though and SQL Server replication, while getting better with each release, does cause hair loss in DBAs. Definitely a lot of work going this route.

I would encourage you to take another look at MS sync framework. We have a situation where we want to synchronize occasionally connected C# clients apps with our Java/Oracle backend. You can use the sync framework providers for the C# client and implement your own custom subclass of KnowledgeSyncProvider for the backend. This will get you half-way there, and show you a good pattern to apply for the rest.
