ABSTRACT:
This white paper provides a comprehensive set of test-proven best practices for properly configuring, deploying, and operating an Oracle 11g database with Oracle's Automatic Storage Manager (ASM) on an HP Enterprise Virtual Array (EVA), using Continuous Access (CA) as the remote copy infrastructure. Specifically, this paper addresses our findings upon investigating the following fundamental deployment issues:
- The best way to configure an Oracle 11g database on the EVA for replication and how that configuration does or does not differ from standalone (nonreplicated) configuration
- The effect of replication method, bandwidth, latency, and distance on replication behavior
- The effect of synchronous, asynchronous, and enhanced asynchronous replication on database performance, and the practical considerations for choosing the best method to use
- The effect of the distance between sites
- What you need to know about your Oracle application to properly size the remote link
- Best practices for the major elements of the deployment (servers, storage, interconnect, and database)
