7.3.3 Setting up the Job Distribution Attributes page

On the Job Distribution Attributes page, specify the following settings:

Settings for distribution to suspended destinations
Settings for job distribution methods
Settings for package split distribution

Figure 7‒41: Job Distribution Attributes page

This page is displayed only for the following job types:

Install package
Transfer package to relay computer
Send package, allow client users to choose (Split distribution range is up to the system to which the managed computer is connected)

Note, however, that you can select a job distribution method only for the Install package job. For the Transfer package to relay computer and Send package, allow client users to choose jobs, the Unicast distribution option is always selected and cannot be changed.

Organization of this subsection

(1) Distribution to suspended destination
(2) Distribution methods
(3) Split distribution settings

(1) Distribution to suspended destination

In this area, select whether to distribute a job to suspended destinations. By default, Do not distribute is selected.

If the managing server or any system on the route to the destination is suspended, file transfers are suspended for jobs for which Do not distribute is selected. However, file transfers are not suspended for jobs for which Distribute is selected, even if the system is suspended. In this case, other jobs are distributed ahead of the job that is being suspended.

If you select Distribute, you cannot perform split distribution. Note also that because jobs for which Multicast distribution is selected cannot be suspended, the settings for Distribution to suspended destination take effect only if you select Unicast distribution.

(2) Distribution methods

For the Install package job, you can select either Unicast distribution or Multicast distribution. By default, Unicast distribution is selected.

If you select Unicast distribution, the host system sends a single packet to a managed computer at one time. This means that the number of packets sent from the host system increases as the number of computers increases. However, if you select Multicast distribution, the host system can distribute jobs to any number of computers by only sending the packets required for a single job. Accordingly, if you distribute the following kinds of jobs by using multicast distribution, you can reduce the amount of transmission compared to unicast distribution:

Jobs that are distributed to numerous destinations
Jobs that distribute large packages

When jobs are distributed to relatively few destinations, or the package size is small, using multicast distribution makes file transfer less efficient. In such cases, select Unicast distribution.

Note that if you perform multicast distribution, you need to specify settings on the relay system and host system.

Note also that if you use multicast distribution, you cannot perform split distribution of packages. This means that if you select Multicast distribution, you cannot specify settings for Split distribution settings, which is described below.

If the destination is an agent for UNIX, you can select only Unicast distribution.

(3) Split distribution settings

In this area, specify whether to perform split distribution of packages. If you select Split package and then distribute, the package is split into the specified size before transfer. You can also specify the interval (Distribution interval) between transfers. These settings enable you to distribute even a large package without imposing a load on the network.

Split size

Specify the split size of a package. The package is split into the specified size. Specify a value in kilobytes or megabytes. The maximum specifiable size is 2,097,151 kilobytes. The default value is 1 megabyte.

The system compares the split size specified on the distribution-destination agent and the split size that you specify here. The system then splits the package by using the smaller split size. The split size is applied to each package to be distributed. When you distribute multiple packages, any packages smaller than the split size are distributed without splitting.

Distribution interval

You can specify the interval at which each split package is transferred during split distribution. Specify a value from 1 minute to 24 hours. The default value is 1 hour.

Note that the system actually uses the distribution interval specified on the side where the specified split size is used. If the specified split size is the same on both sides, the system uses the value specified on the subordinate system, and also uses the distribution interval specified on the side where the specified split size is used.

Note

If you select Split package and then distribute, you cannot perform multicast distribution.
