RM 7.4

Hi...do I read that correct that RM 7.4 Server requires another complete re-install and not just an EAR upgrade?  We did this for RM 7.3...

Re: RM 7.4

Yes, you have to do a full upgrade. It's because of the parallelization framework that's been integrated into the guts. I know it's a PITA but think of the POWAH you get!

Re: RM 7.4

Thanks T-Bone.  Your Darth Vader inspiration allowed me to attempt this.  Unfortunately I got an installation error while trying to install on headless Linux:

Re: RM 7.4

Hey Scott,

 

My colleague Jesús was a great help for this and forwarded along your installation folder.  I was able to execute with your installer.xml on linux and windows without errors when I added in my own file locations.  I think the big issue I noticed is that it looks like it is set to write to the exact same location as your 7.3 install.  

 

This seems like the issue to me, the file architecture is very different between versions and likely the operating system isn't able to differentiate or locate the correct files.  Lets try changing your headless installation location to a seperate path and lets see how it goes.

Re: RM 7.4

Hi thanks for writing back.  No sorry I had changed the installation folder to a new one.  I guess i sent you a prior version of installer.xml.  Here's what I'm using (with some info XXX'ed out):

Re: RM 7.4

ok now what's the magic trick to get my extensions to load?  I put them into the usual extensions folder (web mining and text mining), rebooted the server.  Nada.

Hi Scott,

 

that's strange. It worked for me without problems. Perhaps disk full?
