Using NSD - A Practical Guide HND202 - LAB

Rob Gearhart/Elliott Harden HND202 - Lotusphere 20071 Using NSD – A Practical Guide Overview Introduction This lab is intended to provide IBM Lotus Domino® Administrators an idea of the data that can be used in examining server crash and performance issues. Needless to say, a complete analysis of NSD is not possible within the allotted time. This lab focuses on using Call Stack data and Memcheck data perform a preliminary analysis and get you started in the right direction. Contents This lab contains the following topics: Topic See Page Section I: NSD Basics 2-6 Section II: Call Stacks 7-13 Section III: Memcheck – Shared Memory 14-26 Section IV: Memcheck – Process Memory 27-33 Section V: Memcheck – Resource Usage Summary 34-36 Section VI: Correlating NSD Output 36-40 Section VII: NSD Checklist 41 Section VIII: Case Studies 42-47 Appendix: Student Answer Key 48-68 Original vs. Newer Format Within the ND7 timeframe, NSD has undergone many format and behavioral changes. Many of these changes have been back ported to ND6. x (as of ND6. 5. 5). Within this lab, we refer to both formats, where the original format in ND6 is applies to versions 6. 5. 4 and earlier, and the newer format applies to versions 6. 5. 5 and later, including ND7. x. Where appropriate, we indicate the different KEYWORDs that can be used for searching within an NSD in the Newer vs. Original Format. Please refer to page 3 for more discussion on the NSD back port for existing versions of ND6. x and ND7. x, referred to as the NSD Update Strategy. Focus on Domino Server Due to time constraints, this lab is focused on troubleshooting Domino Server crash and hang/performance issues. However, many of these techniques can also be applied to IBM Lotus Notes® Client crashes and hangs. Please feel free to discuss these additional troubleshooting techniques with the lab instructors.
