Use Quotas to define limits on the amount of storage that a user or a group of users can consume at a network, Instance, or database/tablespace level.
Level |
Allows you to... |
Database-Tablespace |
define a Quota for a user or group of users at the database or tablespace level. |
Instance |
define a Quota that places limits on a specific Instance for a user or group of users. This means that the Quota you set for a user or group of users will be monitored on each computer and Instance included in the Quota. |
Network |
define a Quota that place limits over multiple machines and databases/tablespaces. You can place network level limits on users or groups of users for all the computers (or a chosen subset) or databases/tablespaces in your environment. This enables you to define quotas that affect multiple machines on your network. |
By providing you with the ability to define Quotas at different levels, you can control precisely how much storage a user can consume, not only on specific Instances, but on specific databases, tablespaces, and groups within your organization.
TIP: A Quota is checked by aggregating the storage usage statistics stored in the Enterprise Repository. The Quota Checker job runs on the Tivoli Storage Resource Manager Server machine and does not gather new statistics from any of the Agent machines - the statistics used have already been gathered by separately scheduled Scan jobs. For best results, schedule the Quota Checker to run after your Scan jobs have completed. This ensures that your quotas are checked against the most recent storage usage data.
