Overview
This class provides the knowledge to use UNIX commands and utilities, and to develop applications in the Open System Services (OSS) environment on HPE NonStop servers. The lectures and labs focus on OSS basics, commands, utilities, and development tools. In addition, students are introduced to OSS application programming interface (API) usage and the OSS sockets interface.
In addition to becoming familiar with Open System Services (OSS) architecture, interfaces, and procedures, students gain the skills needed to optimize HPE NonStop systems so users experience smooth functioning IT operations. Students also gain valuable hands-on experience managing an Open System Services (OSS) environment. This course prepares students for advanced learning courses in the HPE NonStop curriculum.
