Technical Bulletin: Production version of application points to test version of services and DB after failed promotion of a patch

In certain promotion scenarios from the Testing stage to the Production stage, the Production user interfaces of an application version may be misconfigured to point to the Test web service(s) and database.  The issue happens in some cases after a failed promotion from Test to Production for a patched version of the application.

Symptoms

If you attempt to promote a version to Production and the promotion fails (for whatever reason), SaaSGrid will automatically rollback the attempt. After this process, in some cases, the user interface components of the Production version will be configured to point to the Test version's interface, services and data. The resulting user experience will be that the application simply doesn't work, or that it works but the users see no data.

Resolution

Apprenda has issued HotFix #1326 to address this problem for customers running the affected versions listed below. This problem has since been resolved and does not occur in later versions. Customers can apply the HotFix or upgrade to the next SaaSGrid release. 

Should I apply the HotFix?

Customers running the affected versions of SaaSGrid (see below) who intend on patching their application in a Production environment should install the HotFix.

What does the HotFix Entail?

The fix involves updating your SaaSGrid Repository with a patched DLL and redeploying one of SaaSGrid's core services via the Operations Center.

Is there a Manual Workaround?

If the symptoms apply, it is possible to manually reconfigure the affected websites in IIS to resolve this situation. The number of websites affected that need reconfiguration will be equivalent to the number of customers your application has.

How do I obtain the HotFix?

Contact Apprenda Client Services (support@apprenda.com) and we will either provide you with HotFix #1326 or apply the patch for you free of charge.
