Revision generation

The purpose of the revision generation is as follows: when the configuration is revised, the
generation for the applications not affected by the revision remain the same.

The use of a repository is an absolute must for this revision generation (see the statement

on page 162). The repository must be created when generating the previous

version or updated to the new status.

When creating the

ubbconfig

file, the generator

config-tux

must generate unique iden-

tifiers for each application. The same identifiers must then be used in a revision generation
like in the first generation. In the case of a first generation with an empty repository, a gen-
eration number is written to the repository for each application so that this number will be
used to generate the identifiers (see the statement

The user must perform the following steps when revising the configuration so that no user
data is lost from an application:

–

Adapt the configuration file
The modifications to the configuration, e.g. new hosts and new applications must be
defined in the input file of the configuration generator

 config-tux

.

–

Perform the generation
The generator reads the configuration file and generates, among other things, the gen-
eration file

 ubbconfig

and shell scripts.

The following steps must be performed on all hosts affected by the modifications:

–

Terminate the application normally
The application must be terminated using the command

tmshutdown -y

on the MAS-

TER host.

–

Execute scripts

–

Restart the applications
