Configuring the Maximum jobs per client for NetBackup for Oracle
The following procedure shows how to set the attribute.
To configure the maximum jobs per client
- In the left pane of the NetBackup Administration Console, expand NetBackup Management > Host Properties.
- Select Master Server.
- In the right pane, double-click the server icon.
- Click Global Attributes.
- Change the Maximum jobs per client value to 99.
The Maximum jobs per client specifies the maximum number of concurrent backups that are allowed per client. The default is 1.
You can use the following formula to calculate a smaller value for the maximum jobs per client setting:
Maximum jobs per client = number_of_streams X number_of_policies
Refer to the following definitions:
number_of_streams | The number of backup streams between the database server and NetBackup. Each separate stream starts a new backup job on the client. |
number_of_policies | The number of policies of any type that can back up this client at the same time. This number can be greater than one. For example, a client can be in two policies to back up two different databases. These backup windows can overlap. |
For Oracle backups and restores, the number of jobs is difficult to determine. This difficulty exists because Oracle internally determines when and how many streams to run in parallel to optimize performance.
Note:
Enter a large enough value for the attribute to meet the number of jobs that Oracle runs. You may need to experiment with different values at your site.
