Unison Software Inc, Sunnyvale, California, has garnered additional support for its Maestro job scheduling technology from Sequent Computer Systems Inc and Siemens Nixdorf Informationssysteme AG. Maestro goes up under Sequent’s Dynix/Ptx Unix from the third quarter and on Siemens Nixdorf’s RM systems later this quarter. The workload management software is already up under HP-UX, AIX and Solaris Unixes. Unison is also trumpeting the fact that Maestro is now certified for use with HP OpenView and OperationsCenter, and IBM NetView network management environments. Maestro’s Simple Network Management Protocol manager collects and keeps a list of information that can be communicated to OpenView or NetView graphical user interfaces. According to the company, it tracks Maestro operations and can signal traps (a technique whereby the SNMP agent lets the manager know if an event has occurred). Maestro 4.02 costs from $8,000 for a single system.
