Upgrading in Two Stages
OSI/MHS converts the MS database tables to the D22 or D41 format. While the
conversion is taking place, you can start and use parts of your OSI/MHS subsystem.
The simplest way to do a two-stage installation is by setting keyword values in the
installation file.
Stage 1
Open the installation file as described earlier in this section. Edit the file to reflect your
OSI/MHS subsystem. In addition, make sure that the following keywords are set:
COPY_ISV yes
SECURE_NEW_OBJECTS yes
COMPILE_MS_INIT_PROGRAM no
COMPILE_MS no
CREATE_MS_DATABASES no
ROUTE_DATABASE_CONVERSION yes
Setting ROUTE_DATABASE_CONVERSION to yes insures that the route database
conversion will be done during stage 1 of the two-stage installation; this is a
requirement. You can also add the MS_DATABASE_CONVERSION keyword to the
file at this point, but make sure that it is set to no.
Close the installation file, then run the installation procedure as described in “Installing
Your OSI/MHS Subsystem for the First Time.” Answer no to the following question:
The installation menu appears, displaying values taken from the installation file. You
have set the MS_DATABASE_CONVERSION keyword to no; therefore, it does not
appear on the menu. If the remaining values are acceptable to you, answer yes to
continue with the installation procedure.
When the installation procedure is complete, you can start and use the MR and GI
groups in your OSI/MHS subsystem. You can also go on to stage 2 of the two-stage
installation process.
Stage 2
To start stage 2, open the installation file and change or add the following keywords
and values:
COMPILE_MS_INIT_PROGRAM yes
COMPILE_MS yes
MS_DATABASE_CONVERSION yes
Set all other options to no. Close the installation file, and run the installation procedure
as described in Installing OSI/MHS for the First Time on page 4-11. Answer yes to the
following question:
Are MS groups to be installed? [y]
Are MS groups to be installed? [y]
