Performing the revision generation

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, new applications and connec-

tions must be deﬁned in the input ﬁle of the conﬁguration generator config.

– Perform the generation

The generator reads the conﬁguration ﬁle and generates, among other things, kdcdf

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 kdcshut normal or

kdcdshut warn so that the ﬁles KDCA, R01A, ..., P01A, ..., KDCB, R01B, ...,

P01B, ... are in a consistent state.

– Execute the kdcdf script

The ﬁles KDCA, etc. are ﬁrst copied to the directory old.

The ﬁles KDCA, etc. are then recreated using the

open

UTM utility routine kdcdef [29].

This

open

UTM utility routine kdcupd transfers the data from the old ﬁles to the newly

generated ﬁles.

– Restart the applications

The shell script utmstart.multi is one of many which is generated when the

kdcdf script is executed. This shell script must be executed.
