Failure of computer systems, hardware or software can result in high costs in some applications. Preventive measures are therefore required as a prerequisite for smooth operation:
the use of cluster configurations
special disk peripherals such as RAID systems
software that identifies faults and enables you to switch quickly from defective hardware to backup systems
distribution of a failover cluster on remote computing centers
These measures, together with openUTM, can be utilized to their full potential because openUTM offers global transaction management and comprehensive restart capabilities right up through the client. This makes openUTM especially suited for use in clusters because processing can be continued on a different system after a restart without losing any data or allowing inconsistencies to arise.
Linux systems can, for example, be used as clusters with PRIMECLUSTER RMS. This software detects failures, performs auto recovery and/or automatically switches from defective systems to intact systems (auto-switchover). UTM applications that have been prepared accordingly can continue operation on the intact system immediately or after a system restart.
