IBM Cloud - Structured Ideas

Shape the future of IBM!

We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:

Post your ideas

Start by posting ideas and requests to enhance a product or service. Take a look at ideas others have posted and vote them if they matter to you

  1. Post an idea

  2. Vote ideas that matter most to you

  3. Get feedback from the IBM team to refine your idea

Help IBM prioritize your ideas and requests

The IBM team may need your help to refine the ideas so they may ask for more information or feedback. The offering manager team will then decide if they can begin working on your idea. If they can start during the next development cycle, they will put the idea on the priority list. Each team at IBM works on a different schedule, where some ideas can be implemented right away, others may be placed on a different schedule.

Receive notifications on the decision

Some ideas can be implemented at IBM, while others may not fit within the development plans for the product. In either case, the team will let you know as soon as possible. In some cases, we may be able to find alternatives for ideas which cannot be implemented in a reasonable time.

NOTE: All IBM employees must enter Ideas through this Ideas Portal.

Tunable parameters for SQL Adapter in the Mobile Foundation service

We are wanting to connect to an external Database e.g. Oracle using the SQL Adapter in the Mobile Foundation service (not as the repository for the Mobile Foundation configuration).  

As per:
https://mobilefirstplatform.ibmcloud.com/tutorials/en/foundation/8.0/adapters/javascript-adapters/js-sql-adapter/

And from that link:
dataSourceJNDIName: Optional. Connect to the data source by using the JNDI name of a data source that is provided by the application server. The adapter takes the connection from the server connection pool that is associated with the JNDI name. Application servers provide a way to configure data sources. For more information, see Installing MobileFirst Server to an application server. For example:
                        
<connectionPolicy xsi:type="sql:SQLConnectionPolicy">
    <dataSourceJNDIName>my-adapter-ds</dataSourceJNDIName>
</connectionPolicy>

During our implementation of the mobile application, we encountered SQL Adapter connectivity problems resulting in poor user experience and quality of service. We want to configure the SQL connection using a connection pool so we have greater control over the connection e.g. concurrency and timeouts.

    There are two ways of connecting to SQL DB via SQL adapter:
    1) Define the connection strings and credentials directly in the adapter.xml. Here there is no control over any tuning parameters.
    2) Define a datasource in the application server and use it to connect. This allows applying all performance tuning parameters to the datasource ( outside MFP, at application server level) - connection pool, timeouts etc. Customer should adopt this approach. This is what customer mentioned above by setting dataSourceJNDIName
