Configuring the Maximum jobs per client

The following procedure shows how to set the Maximum jobs per client attribute.

To configure the maximum jobs per client

  1. In the left pane of the NetBackup Administration Console, expand NetBackup Management > Host Properties.
  2. Select Master Server.
  3. In the right pane, double-click the server icon.
  4. Click Global Attributes.
  5. 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.

Note:

Enter a large enough value for the Maximum jobs per client attribute to meet the number of jobs that Informix runs. You may need to experiment with different values at your site.
