Pronto: a fast failover protocol for off-the-shelf commercial databases

F. Pedone, S. Frolund
Proceedings 19th IEEE Symposium on Reliable Distributed Systems SRDS-2000  
To isolate end-users from database failures, we introduce Pronto, a protocol to orchestrate the transaction processing by multiple, standard databases so that they collectively implement the illusion of  ...  The key challenge in implementing this illusion is to enable fast failover from one database to another so that database failures do not interrupt the transaction processing.  ...  ޹ º ¼» S½ «¾ À¿ Á¿ ¨¿  ª à ¢Ä lÅ ÇAE È ª É ¢Ê `Ë Ì ¤Í vÎ SÊ `Ï ÑÐ Î SÒ ¦Å p r zo Ó ª ¤Ô k¯ z Õ ª Ô V¯ w Ö ª × Ø Ù µ fØ f³ ¹ ÚÅ Û» ½ º Ü v¾ Ý ª Þ Áß àÉ ¢Ê Ë Ì Í vÎ SÊ `Ï ÑÐ Î SÒ qá p r zo ãâ ä å ª Ã Ä  ...

2010 Lecture Notes in Computer Science  
To support as much as possible off-the-shelf and third-party tools, the call-level and SQL interfaces, and the remote database accesses protocol adhere to existing standards.  ...  Usually, this allows us to use off-the-shelf databases. -Gray-box: Some key features are exposed to the middleware level in order to provide more efficient, generic solutions and specific protocols.  ...  Appendix A Requirements for Replication-friendly Databases A.1 Requirements To achieve modularity without losing performance, the replicator must have access to a set of features provided by the DBMSs  ...
