– for the MASTER host
a configuration file ubbconfig for the BEA TUXEDO transaction monitor and the shell
scripts crbincf and crtlogs.
– for each host
a shell script crdevqu for setting up the “Queue Device”, “Queue Space” and
“Queues” and for generating the database transaction manager.
The configuration can be performed on a central computer for the entire system. The files
created in the process must then be distributed to the target computers and installed there.
The final tasks which must be performed locally are carried out during this installation. Mov-
ing the final tasks to the target computers eliminates the need to install the transaction mon-
itor on the generation computer. Because the output data for the generation comprises only
text files, the hardware and operating system independence of the configuration process is
also guaranteed. You must observe the different ways in which UNIX and WindowsNT dis-
play the end of a line in a text file if the generation computer and the target computer are
running different operating systems.
In the first version of the configuration tool, the procedure is that change requests are sent
to a central location and that a new configuration process will be implemented from there
only. The configuration generator makes it easier to configure the runtime environment for
T-ORB and T-ORB/Client. Revision generation is described in section 7.3 auf Seite 174.
A central configuration is recommended for the following reasons:
– It does not make sense to change the configuration on the local target computers
because these modifications will be overwritten with the next global update process.
– Another argument against changing the settings locally is that modifications to the hier-
archy of the system often affect more than one host. It is precisely changes of this type
that require consistency checks, which are not possible on the local level.
