One of the most important demands made of business-critical applications is that they should be available 24 hours a day, 365 days a year. System failures, and thus application failures, can be very costly, not to mention the damage to the image of the company running the application.
In addition to the computer configuration, the operating system is central to ensuring high availability. No operating system can provide 100% availability. But BS2000 systems, Unix, Linux and the Windows systems do offer a large number of functions that go a long way toward achieving this.
openUTM supports the high availability offered by these operating systems by means of global transaction management and restart capability. openUTM and the operating system thus complement each other ideally and together ensure practically fault-tolerant operation of the application.
