This WE I was supposed to do the installation on the production server. The process for the migration alfresco 224 to 311 takes too long time to execute ! The prod machine is : windows server 2008 + 30Go RAM + 4CPU Xeon 2.4GHz + on another computer : MSSQLServer 2008 + 20Go RAM + 4CPU 2.2GHz. The number of document is poorly ~70 000. The JVM is configured with Xmx8G and Xms5Go The logs says when I start the application :
At 16% , about 4 days left ! (time estimated). To reach 16% it was running from saturday 14pm to Sunday 10am … and it was only to 16% !! my god !
That's surprising because time length for the process is not proportionnal !! 2 months ago, we've done the migration (there was ~40 000 doc) and on a virtual machine (VMware) and it took a short night …. why with 70 000 docs, it takes 8 times more ??? The time length is not proportional to the number of documents in the repository and I was really surprise ! Finally we rolled back to the current version on the production….the migration having been considered as a failure.
Well I just tested on another virtual machine yesterday evening. The time length was 3Hours to apply the upgrade. My customer has really a problem with its production server….those final customer…..they would better ask to maintain there network by a computer science engineering company, they need expert !
