To be clear, this post is about a white paper that's been out there for more than two months. Access it through the following url.
The focus of the paper is on databases and zones. On SuperCluster, customers have the choice of running their databases in logical domains that are dedicated to running Oracle Database 11g R2. With exclusive access to Exadata Storage Servers, those domains are aptly called "Database" domains. If the requirement mandates, it is possible to create and use all logical domains as "database domains" or "application domains" or a mix of those. Since the focus is on databases, the paper talks only about the database domains and how zones can be created, configured and used within each database domain for fine grained control over multiple databases consolidated in a SuperCluster environment.
When multiple databases are being consolidated (including RAC databases) in database logical domains, zones are one of the options that fulfill requirements such as the fault, operation, network, security and resource isolation, multiple RAC instances in a single logical domain, separate identity and independent manageability for database instances.
The best practices cover the following topics. Some of those are applicable to standalone, non-engineered environments as well.
- CPU, memory and disk space allocation
- Zone Root on Sun ZFS Storage Appliance
- Network configuration
- Use of DISM
- Use of ZFS filesystem
- SuperCluster specific zone deployment tool, ssc_exavm
- ssctuner utility
- Exadata Storage Grid (Disk Group) Configuration
- Disk Group Isolation
- Shared Storage approach
- Dedicated Storage Server approach
- Resizing Grid Disks
