Read and write Values from Configuration File in BizTalk

Question

There is a requirement where Biz talk orchestration read the value dynamically from Config Store.After some process updating the value in config store.
I though to use SQL Server and create one table with single column.Biztalk will call the Storeproc to get the value and similary for update system will call another SP.
Instead of using SQL Server DB is there option to implement this requirement like app.config,BTSsvcxxexe.config ,SSO Config store etc.
If multi-users access the value from Config store and try to update ,how to handle lock mechanism.

Hi BizQ,
Refrain from using BTSConfig file or any custom config file if you have a requirement to update the data. Modifying a
configuration file at runtime can cause some nasty, unexpected behavior inside your application if it's not managed properly.
I would suggest you to use Custom DB or SSO Database in this case.
Both have their Pros and Cons.
SSO Database:
You get out of the box encryption
It is a central store which will service all BizTalk servers within your group
 SSO implements a caching mechanism internally for the data
Custom DB:
By storing the configuration in the database you don’t have to worry about consistency of data across servers like you would with a config file.
Cache needs to be implemented by program to avoid delays in reading from physical file.
In your case I recommend to go with SSO DB as in terms of storing custom configuration data in SSO for End Point/Application
specific information and credentials and potentially configuration information which you also need to write and update at runtime from your code or via an administrator.
You can use Richard Seroter's tool to store values as "Config Store" in SSO database and then write a .net helper
utility to retrieve it using SSOConfigStore class. It has method GetConfigInfo and you need to pass application name with other parameters. It returns ConfigurationPropertyBag from where you can read property name and values.
