1-20 Administrative Products for DB2 Installation Guide
Installation Default Options
An installation option allows you to browse existing input data sets for an
appropriate installation profile and copy the profile to the current installation
data set. This option is useful when you are unsure of the profile name or
contents.
If you reuse a profile from a previous installation session, you must review
the installation options carefully. Verify that the values for the options are
still valid for the current installation. Change any values in order to reflect the
new release. (For example, a database name or plan name might change from
one release to the next.)
Warning! Failure to change the required parameters for the new installation
can cause severe errors when you submit the installation JCL.
For example, if you do not change a DB2 plan name from a
previously specified value, you can overwrite a plan that your
current installation uses.
Installation Default Options
After the Install System generates the installation batch jobs, the user-named
output JCL data set contains a member that establishes values for default
processing options (DOPTs). The member name has the format $xnnDOPT,
where the variable xnn is a three-character ID that is based on the installation
path that you choose for the product.
Some of the BMC Software products use a text options file, while others use
an assembled options module. The $xnnDOPT member contains either logic
to copy the option file to the CNTL data set or an assembly language
program with an options macro call. You can tailor the processing of the
product by editing the default values in the $xnnDOPT member.
When the $xnnDOPT job is submitted, the Install System acts as follows:
• If the $xnnDOPT member is a text options file, the Install System copies
it to the CNTL data set.
• If the $xnnDOPT member is an assembled options module, the Install
System generates it into the APF-authorized library that you specify
during the installation process.
