Sun Cluster Environment (Sun Microsystems Press) Book

Multiple nines--that is, high availability--require multiple machines configured to support each other in a fail-over scenario. If Sun machines make up a critical portion of your back-end operations and you're responsible for satisfying a Service Level Agreement (SLA), you'll want to have a look at what Sun Cluster Environment: Sun Cluster 2.2 has to say about reliability, availability and serviceability. The focus is on the Sun Cluster 2.2 (SC2.2) technology for machines ranging from Sun Ultra Enterprise 2 to Sun Enterprise 10000, but there's a lot about availability engineering in general. You'll want to have a look even if you're not exclusively concerned with Solaris machines. As part of the Sun Blueprints series, this book combines descriptions of technology--how SC2.2 works--with advice on implementing it. The authors recognise that every implementation of SC2.2 is unique, but provide remarkably specific how-to instructions (including command-line listings) on broad classes of implementation. For example, they explain how to configure Oracle, Sybase and Informix databases to work in a SC2.2 environment by detailing the configuration files and procedures that each requires and noting where the potential for problems exists. Similar attention goes to the process of building a Network File System (NFS) file server for high availability under SC2.2. --David Wall Topics covered: using Sun Cluster 2.2 to provide maximum uptime for applications--especially Oracle, Sybase and Informix databases--running on Solaris machines. Configuration of public and private interfaces, management of cluster partitions and SCSI configuration all get attention, as do environmental considerations such as cooling and redundant electrical power.Read More
