As organizations rely more and more on computer applications, it is vital to
safeguard the contents of databases. This guide explains the many mechanisms that
Caché provides to maintain a highly available and reliable system. It describes
strategies for recovering quickly from system failures while maintaining the integrity
of your data.
Caché write image journaling technology protects against internal integrity
failures due to system crashes. Caché backup and journaling systems provide
rapid recovery from physical integrity failures. Logical database integrity is ensured
through transaction processing, locking, and automatic rollback.
In addition, there are other mechanisms available to maintain high availability
including shadow journaling and various recommended failover strategies involving
Caché ECP (Enterprise Cache Protocol) and clustering. The networking capabilities
of Caché can be customized to allow cluster failover.
