Prerequisite checker

Technote (FAQ)
Problem
Trying to install WebSphere 3.5 and getting a error wrong version of DB2 or Sybase
Solution
You are trying to install WebSphere Application Server 3.5 and you are not able to, because you get a message that you have the wrong version of DB2 or Sybase. This technote explains how to disable the prerequisite checker so that Websphere Application Server will install.

Note: Support of certain levels of database products require additional Websphere 3.5 ptfs; always check the Websphere Application Server Standard/Advanced prerequisite page to ensure you have all of the prerequisite levels required:
http://www-4.ibm.com/software/webservers/appserv/doc/v35/prereq.html

Also note the DB2 edition support; Websphere Application Server 3.5 currently only lists support for DB2 Enterprise Edition. Any other DB2 edition will generate this same prerequisite checker error.

You can do these steps on the following platforms.
SOLARIS
AIX
HP-UNIX

Disclaimer: By doing these steps you will turn off the prerequisite checker and WebSphere will install on any server no matter what is installed.

The installation prerequisite checker is checking for different versions of DB2 and Sybase.
Specifically, the problem occurs when installing:

DB2 7.1 Fixpack 1
DB2 6.1 Fixpack 5 (not on AIX)
Sybase 11.9.2 (Solaris only)

Procedure:
1.Copy the prereq.properties file from /cdrom to /tmp
2.Edit the /tmp/prereq.properties file, and change prereq_checker=1 to prereq_checker=0
3.Begin WAS install, using the following command :
install.sh /prereqfile /tmp/prereq.properties

This information can also be located in the README for 3.5 fixpack 1.

NT 4.0 & 2000
