The Replication Live Servers connected to the Master Live Server discontinues replication and attempts to log on again to the Master Live Server periodically in order to continue replication. Log attempts are written to the server log.

Publications are no longer possible and the publication which was running at the time of disruption fails. You will see an error message if you try to start a publication or publication preview with CoreMedia Studio .

Error behavior

The clients hang up or receive error messages until the server is restarted.

Error correction

Error behavior

Transactions which are active at the time of failure or which first notice the failure are terminated with an error. The error is passed to the server and clients. Further publications lead to errors. The Replication Live Server sdetect the malfunction andattempt to reconnect. You can see the login attempts in the server log. Transactions started after the server has detected the database failure are blocked until a new database connection is created. Clients (replication of the Live Server, publication, etc.) remain paused. Appropriate messages are written to the server log.

Error correction

To trigger a restart of the Master Live Server a deployment may use the Spring Boot health indicators provided below the URL :8081/actuator/health. You can find the list of available health indicator endpoints in the Actuator Endpoints section of the Section 4.10.2.1, “CoreMedia Health Indicator” in Operations Basics.

As soon as the database is available again the server creates new connections to the database (watch the server log) and blocked transactions are released. Note: Error-free operation after a database breakdown cannot be guaranteed, since external components are also affected (for example the JDBC driver).
