The Oracle Exadata IO Resource Manager Limit Clause, part 2
Jul 25th
In my previous post I described how the IO resource manager (IORM) in the exadata storage can be used both to guarantee a minimum amount of IO a database can get (which is what is covered in most material available), but also to set a maximum amount of IO. This is what Oracle calls an inter-database resource manager plan. This is set and configured at the cell level using the cellcli with ‘alter iormplan dbplan’.
The Oracle Exadata IO Resource Manager Limit Clause
Jul 19th
The Exadata IO Resource Manager (IORM) is a fundamental piece of the exadata database machine since the beginning. The function of the IORM is to guarantee a database and/or category (set via the database resource manager) gets the share of IO as defined in the resource plan at each storage server. The “share” here means the minimal amount of IO. This is widely known and documented in the Exadata documentation. Having a minimal amount of IO means you can guarantee a service level agreement (SLA).
