The Linux distribution that you want to install your DB2 product on may not be 'DB2-ready' out of the box and therefore may not have some of the packages that DB2 requires to run. This section discusses the 'out-of-the-box' preparation work that you need to do with your particular Linux distribution to enable it for DB2 Version 7.
The only preparation work that you need to do to install your DB2 product on a workstation that is running Red Hat Linux Version 6.0 or later is to add the required pdksh package that is not part of a Red Hat default installation. This package, called pdksh-5.2.xx-x, where xx-x represents a point release level, is available in the /RedHat/RPMS directory on the Red Hat CD-ROM. Refer to your Linux documentation for information on how to install this package using the rpm command.
Caldera Open Linux (Caldera) Version 2.3 is missing the required pdksh package from a default installation. This pdksh package is on the Caldera Version 2.3 CD-ROM, however it is not compatible with DB2. As relationships strengthen between IBM and Caldera, you should expect this problem to be fixed, in the meantime, you can use a Red Hat pdksh package.
To enable your Caldera workstation for a DB2 installation using a Red Hat pdksh package, download the pdksh-5.2.13-3.i386 package or a later version from a local Red Hat mirror site. You can find the latest list of mirror sites at http://www.redhat.com/download/mirror.html. Because this is a Red Hat package, you would receive a dependency error on the glibc package) if you try to install it. The glibc package is automatically installed with Caldera Version 2.3. You can therefore ignore this error because it is a result of different naming conventions between distribution vendors. To bypass the error, you will have to install this package using the no dependencies option. For example, you could use the rpm -i --nodeps command to install this package without dependencies. Refer to your Linux documentation for information on how to install this package using the rpm command.
To enable your Turbo Linux Version 3.6 or later workstation for DB2, you need to add the pdksh package. This is the only prerequisite that is missing from a default installation. This package is available on the Turbo Linux CD-ROM and is located in the /TurboLinux/RPMS directory. Refer to your Linux documentation for information on how to install this package using the rpm command.
The SuSE Version 6.3 default installation is simple to enable for DB2. DB2 requires glibc Version 2.1.2 or higher to run. SuSE Version 6.3 comes with this package, but the distribution refers to this package by a different name. SuSE calls this package shlibs. This causes problems because the db2setup utility fails to recognize the existence of the required glibc package, and ultimately fails. To address this problem, a dummyglibc package is included on the DB2 CD-ROM. If you install this package, the installation will run smoothly. The package is called glibc-2.2.1-2.i386.rpm and is located in the /db2/install/dummyrpm directory on the DB2 CD-ROM. Refer to your Linux documentation for information on how to install this package using the rpm command.
