Software considerations
v (Client and Server) To use Kerberos authentication, install the Linux krb5
Kerberos support via the operating system Kerberos packages.
v One of the following browsers is required to view online help and to run First
Steps (db2fs):
– Firefox 3.0 and later
– Google Chrome
– Safari 4.0
v An X Window System software capable of rendering a graphical user interface is
required if:
– you want to use the DB2 Setup wizard to install a DB2 database product on
Linux operating systems, or
– you want to use any DB2 graphical tools on Linux for x86 and Linux on
AMD 64/EM64T.
v Micro Focus does not offer support for any of its COBOL compiler products on
SLES 11.
Security-enhanced Linux considerations
On RHEL systems, if Security-enhanced Linux (SELinux) is enabled and in
enforcing mode, the installer might fail due to SELinux restrictions.
To determine if SELinux is installed and in enforcing mode, you can do one of the
following:
v check the /etc/sysconfig/selinux file
v run the sestatus command
v check the /var/log/messages file for SELinux notices.
To disable SELinux, you can do one of the following:
v set it in permissive mode and run the setenforce 0 command as a superuser
v modify /etc/sysconfig/selinux and reboot the machine.
If your DB2 database product installs successfully on a RHEL system, DB2
processes will run in the unconfined domain. To assign DB2 processes to their own
domains, modify the policy. A sample SELinux policy is provided in the
sqllib/samples directory.
