Configuring the Maximum jobs per client

The Maximum jobs per client specifies the maximum number of concurrent backups that are allowed per client.

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.

To configure the maximum jobs per client

  1. Open the web UI.
  2. On the left, select Hosts > Host properties.
  3. Select the primary server.
  4. If necessary, select Connect. Then select Edit primary server.
  5. Select Global attributes.
  6. Select the appropriate value for Maximum jobs 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.
