I have installed Domino 8.0.1 and DB2 9.5 on one computer (Windows 2003 32bit). I know official requirements are herehttp://publib.boulder.ibm.com/infocenter/domhelp/v8r0/topic/com.ibm.help.domino80x.doc/DOC/H_SUPPORTED_PLATFORMS_AND_HARDWARE_AND_SOFTWARE_REQUIREMENTS_OVER.html => DB2 9.1 but I hope that DB2 9.5 will work too.
The step “Enabling the DB2 Access Server” (http://publib.boulder.ibm.com/infocenter/domhelp/v8r0/topic/com.ibm.help.domino80x.doc/DOC/H_ENABLING_DB2_SERVER_ACCESS_STEPS.html) was finished without error but I have some problem with “Testing the DB2 Access server configuration” (http://www.abclinuxu.cz/images/screenshots/5/3/102535-store-for-snapshots-40149.png) now.
