Websphere 7 installation on linux broken?

alosii · 12-08-2008, 06:02 PM

Hey guys!

I've downloaded the trial version of the WebSphere Aplication Server 7.0.

They have a little shell called lunchedpad.sh. After trying to run it, the default browser opens(firefox in my case). There is a little link to launch the real installer, after clicking on it I get an error on the console:

Code:

WAS/install: line 435: [: -ge: unary operator expected

Chaking the install.sh on that line you can see:

Code:

...
  if [ $version -ge 5 ]
...

I've tried to run the WAS installer in silent mode and in console mode, and i have the same result. This is under Fedora 9. Any ideas?

My guess would be that $version is not set so the substitution becomes

Code:

if [  -ge 5 ]

which is invalid syntax.

Sloppy coding on IBM's part. They should have either ensured the variable is set or at least surrounded it with quotes.(Both being preferable).

Having suffered through installing some of the websphere application integration products on AIX in a past life, I don't envy you this task.

Thanks for responding so fast GazL,

After adding the "" around version i get:

Code:

 line 435: [: : integer expression expected

By looking at the surrounding lines it seams that the installer wants a red hat version number...

Code:

if [ -r /etc/redhat-release ]
	then
        	release=`cat /etc/redhat-release | awk '{print $7}'`
		version=${release%%\.*}
                if [ $version -ge 5 ]
	        then

Im starting NOT to like websphere...

Adding the quotes would have fixed the syntax error, but it still leaves you with a logic error in the code because the comparison will be against a null value.

From looking at that snippet of code you listed, it looks like its looking for a file /etc/redhat-release that contains a version number like '5.0'. Is there a /etc/fedora-release file? If so copy it to
/etc/redhat-release, or create a /etc/redhat-release yourself and stick '5.0' in it.

The install could have other issues though as you're not installing on a true redhat system, so expect further issues, but you may get lucky.

You're welcome, and I know *exactly* how you feel on that one!

Best of luck with it.

Edited - didn't spot the -r test on /etc/redhat-release first time.
