A "guided tour" of the OpenVMS boot, startup and shutdown sequences.

This part will discuss the OpenVMS boot, startup and shutdown sequences, including the console interface to Alpha and Integrity servers.

Understanding the boot sequence is important, especially on Integrity Servers, where the view from EFI shell is very different to that provided by OpenVMS.

Setting up OpenVMS systems and clusters requires writing DCL to handle the startup and shutdown of the complete system, including the applications. A consistent and modular approach is important in order to minimise the difficulty of trouble-shooting as changes are made over time.

Making changes to operational systems - firmware updates, operating system updates and hardware replacement.

This part will discuss the planning and implementation of changes to production systems with minimal disruption, working within short periods of scheduled downtime.

Careful planning and representative testing are crucial. It is essential to verify the exact sequence of operations requried and the approximate timings of each step. There are many pitfalls and traps waiting for the unwary. Working swiftly and accurately under time pressure can be extremely stressful, especially when unexpected events occur. Checklists are invaluable. As part of this discussion, we hope to offer some useful practical advice on techniques for implementing the changes in an OpenVMS environment.

Using Locking Performance Data to Solve Cluster Problems

This session describes how you can detect potential I/O performance bottlenecks using data OpenVMS is already keeping behind-the-scenes on locking activity rates and on lock queues. It also includes real-world examples of how these techniques have been used to resolve a variety of problems in OpenVMS Clusters.

Volume Shadowing Best Practices

This session describes how to optimize your use of Host-Based Volume Shadowing for OpenVMS. It will cover questions related to such things as using Write Bitmaps, how to craft Mini-Merge policies, and considerations related to Shadowing Full-Copy and Mini-Copy operations.

Best Practices for Multi-site and Disaster Tolerant OpenVMS Clusters

For customers who are building multi-site OpenVMS clusters for purposes of Disaster Tolerance or Disaster Recovery, this session provides answers to questions like:

- What things can I do to maximize performance in a multi-site cluster?
- How far apart can my sites be?
- How many sites can I have in a single cluster?
- When should I use IP as a Cluster Interconnect (IPCI)?
- Should I use different Site Numbers in my multi-site OpenVMS cluster?
- How should I set Read Costs for Shadowing?
- How should I number my disk devices and choose nodenames?
