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 60). The repository must be created when generating the previous

version or updated to the new status.

The applications use host resources such as authorization keys (

KEYVECTOR

) and port num-

bers (

PORTADDRESSES

). The applications not affected by a revision must use the same

resources. The authorization keys and port numbers are stored in the repository for each
application.

When creating the

kdcdf

script, the generator

config

must generate unique identifiers

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

The following further characteristics or values are entered in the repository for each server
application:

–

KDCFILE

,

 DOUBLE

If the

 KDCFILE

is maintained in duplicate for security reasons, the characteristic

DOUBLE

is stored and can then be taken into account during the next generation.

–

PGPOOLFS

The

 PGPOOLFS

parameter defines the number of files across which the page pool is

distributed. This number is entered in the repository and can thus be evaluated during
the next generation.

–

RECBUFFS

RECBUFFS

defines the number of files across which the restart area is to be distributed.

This number is stored in the repository and read during the next generation.
