Note that IBM officially supports this distribution for DB2 UDB V8.2 only for application development or client purposes.
Before installing DB2 UDB V8.2 on Fedora Core 4, you must install the following compatibility libraries:
To inherit the DB2 instance environment from another home directory, create databases, dynamically load the DB2 libraries, and other tasks, you must disable SELinux or modify the default SELinux policies. You can disable SELinux at run-time by running the following command as root:
# /usr/sbin/setenforce 0
If you have enabled your firewall (the iptables service), and you want to enable external connectivity to your DB2 server, you must open up ports 553 and db2 get dbm cfg | grep SVCENAME in your firewall.
