The following list describes how to set up the target application server.
The target application server is installed as follows:
1. Set up the installation directory.
2. Go to the installation directory and execute:
3. Copy MCOD-specific R3SETUP templates from sapservX to the installation
directory. For details, see
DB2/390: MCOD installation tools,
Important: It is highly recommended when migrating with SAP tools that you
reinstall the SAP instance or instances using R3SETUP, even if you are
reusing the same application server hardware with SAP instances already
installed. This ensures that all required MCOD settings are correctly
implemented in the environment and instance profile variables, as well as
plans bound and grants executed.
To preserve any changes you have made in SAP profiles, take a copy of the
files from /usr/sap/<SID>/system/profile, as well as the .dbenv_xxxx files from
the $HOME directory of <sid>adm user, prior to starting the install. Upon
completion of the migration, you will need to integrate the parameters in the
new instance and those in the files you have saved. A complete backup of the
application server is highly recommended prior to reinstalling to allow a point
of return in case of unforeseen error.
