![]() If the problem persists, contact customer support, and provide them the session tracing ID of '%.*ls'. ![]() Azure SQL Managed Instance resource limits.ĭatabase '%.*ls' on server '%.*ls' is not currently available.vCore-based limits for single databases.For more information, see Transient errors. Your application must catch error 40197, log the embedded error code (%d) within the message for troubleshooting, and try reconnecting to SQL Database until the resources are available, and your connection is established again. Reconnecting automatically connects you to a healthy copy of your database. Some examples of the error codes are embedded within the message of error 4010, 40143, 40166, and 40540. The error code (%d) embedded within the message of error 40197 provides additional information about the kind of failure or failover that occurred. You receive this error when the service is down due to software or hardware upgrades, hardware failures, or any other failover problems. The service has encountered an error processing your request. For more information, see Errors 4000 to 4999 Other, non-transient scenarios involving this error message are described in the MSSQL Errors documentation.Ĭannot open database "%.*ls" requested by the login. This error may be logged on SQL Managed Instance errorlog, for a short period of time, during the last stage of a reconfiguration, while the old primary is shutting down its log. See the SQL Server errorlog for more information. List of transient fault error codes Error codeĭatabase 'replicatedmaster' cannot be opened. The following table lists various transient errors that applications can receive when connecting to Azure SQL Database. However, these events can occasionally take longer to finish, such as when a large transaction causes a long-running recovery. Most reconfiguration events are generally short-lived and should be completed in less than 60 seconds at most. Database reconfiguration events occur because of a planned event (for example, a software upgrade) or an unplanned event (for example, a process crash, or load balancing). This kind of error condition is called a transient fault. This dynamic behavior might cause your client program to lose its connection to the database or instance. The Azure infrastructure has the ability to dynamically reconfigure servers when heavy workloads arise in the SQL Database service. Transient fault error messages (40197, 40613 and others) New theory, I think to retry 400 response codes with retry-all-errors the following lines need tweaking (never played with C so apologies if I'm way off again).You can use Azure SQL Connectivity Checker to detect and fix a wide variety of connectivity errors to Azure SQL Database, Azure SQL Managed Instance and in Azure Synapse Analytics environments. Reading the code again I think this was way off. I think this is because -fail is causing this if to hit and the 400 to be counted as an error. I think either a note in the docs for retry-all-errors to highlight that -fail is needed to retry http error codes or tweaks to the source so any http error code is retried when retry-all-errors is set. This option is used together with -retry. I expected the 400 response to be retried. curl "" -retry 5 -retry-all-errors -X POST -fail will retry the 400 response. The endpoint returns a 400 status code with a body of hello world.Ĭurl doesn't retry the request and returns the body.Īfter reading through the code I discovered that by adding -fail to the command I could get the behaviour that I wanted. ![]() First up, thanks for curl it's awesome!
