The SHARE Academy z/OS Bug Busterz class is presented by experienced z/OS Level 2 professionals and will provide you with the skills to analyze and make sense of diagnostic data captured by z/OS. You will gain the knowledge necessary to perform preliminary analysis of dumps and trace data using IPCS, and learn how to capture information through diagnostic tools, including GTF trace, CTRACE and SLIP. The class is designed for z/OS Systems Programmers and Application Programmers that support products running on z/OS, and will include a pre-event webcast. No prior IPCS experience is required.
