Administering Satellites Guide and Reference

Batch Modes

There are three different modes of batches in the satellite environment:

Group

To set up and maintain the database definition and data on satellites, you use group batches. A group batch is associated with a particular application version. In addition, each satellite is associated with an application version. When a satellite synchronizes, it downloads and executes the group batches for its particular application version. The satellites always execute the batch steps of the group batches in the same order. Before the group satellites execute the batch steps, they are all similar. When all the satellites have executed all the batch steps of all their group batches, they remain similar.

Because the satellites execute the group batches to maintain their database definition and data, you only have to work with the batches, instead of individually maintaining the hundreds, if not thousands of group satellites.

A group batch will be either a setup, update, or cleanup batch. For more information, see Group Batches. You work with group batches by using the Edit Application Version window in the Satellite Administration Center. You can also create an unassigned batch using the Create Batch window in the Satellite Administration Center, then assign it to a group when you edit the application version. For more information about these windows, refer to the online help for the Satellite Administration Center.

Fix

In any environment, problems will occur. A fix batch is one that is created to fix a problem on one or more satellites. This is in contrast to the purpose of group batches, which is to set up and maintain the database definition and data for a specific version of the end-user application. Because of this difference of purpose, fix batches are not assigned to a specific group or to an application version. For more information, see Fix Batches.

Unassigned

An unassigned batch is one that maintains its mode until it is assigned to either:

• An application version, to be executed by a group as a setup, update, or cleanup batch
• A satellite, that will execute the batch as a fix batch.

You can modify an unassigned batch in any fashion, and you can also delete it. If you assign an unassigned batch to an application version, the batch becomes a group batch. If you assign the batch as a fix batch, which you use to make changes to a specific satellite, the unassigned batch becomes a fix batch. In both cases, the change in how the batch is used permanently changes the mode of the batch. That is, the batch cannot be changed back to an unassigned batch.

You work with unassigned batches by using the Create Batch and Edit Batch windows. For more information about these windows, refer to the online help for the Satellite Administration Center.
