Error ID: SQL Server error 976
Error Message:
Cause:
Primarily this error occurs when something tries to run against a database in an Availability Group when the instance is acting as the secondary and therefore the databases are read only. For example, SQL Agent jobs may be configured on both the primary and secondary instances to run integrity checks against the databases (known as DBCC CHECKDB). They would succeed on the primary as they are read/write databases, but would fail on the secondary as they are read only. It is possible to configure both instances as read/write, but this requires additional licensing from Microsoft. The error can also occur for other reasons, such as a disconnected replica, suspended data movement or a temporary network issue.
Solutions:
If the error has occurred because of a SQL Agent job trying to run against a database on a secondary instance that is read only, the solution is to amend the job so that it only runs if the instance is the primary. There is no check box to tick unfortunately, it needs a step adding at the beginning of the job to determine whether it is running on the primary or the secondary and then only move onto the next step if it is the primary. If the error has occurred due to another reason, further investigation is required to identify the specific cause (e.g. a network issue).

“We first approached Xynomix for advice on Oracle licensing. They saved us money there, and a year on we have a full database management contract with them.”
Data Systems Manager – Media Industry
“Xynomix investigated the performance bottlenecks that we were experiencing after updating our data warehouse application. After investigating the system, Xynomix concluded that the database server’s cache-hit rates and available memory were both low, which was impacting negatively on performance. The technician rectified this and we are now very happy with the function of the application.”
Network Administrator – Dragon LNG Ltd
“We recently installed a new application which ran on Oracle but was unsure how to correctly license the environment. As a result, we engaged with Xynomix to advise on how best to do so. Xynomix ran an Independent Oracle License Review, which gave us full visibility on our license compliance. They highlighted the restrictions around various license types, whilst also detailing how to avoid any pitfalls moving forward.”
