3 instances of OFBiz on this VM: trunk: the trunk version stable: the last stable version (currently 13.07) old: the previous stable version (currently 12.04) {checking} Note: Only run the ofbiz demos using the 'ofbizDemo' user, never run as root. To do this sudo to the ofbizDemo user: sudo -s -u ofbizDemo -H sudo uses OTP (One Time Password), so you not only need to be registered as a sudoer (ask Infra) but also to use a tool like Donkey on Ubuntu (jleroux: I use that) to generate the OTP Then you can start/stop as required. To check if the demos are being run as the ofbizDemo user: ps aux | grep ofbizDemo The first column on the left tell you the username the demo is being run as - it should say ofbizDemo (UID) or 9997 (GID) ! {checking} Also note that the demos are usually updated and started/stopped automatically using the check-svn-update.sh script in this directory, it is run by an ofbiz cron job every 24 hours at 3 AM. You should therefore only need to start/stop manually if there is a problem. If you want to tackle only a single instance you can respectively use trunk-manual-nicely.sh stable-manual-nicely.sh old-manual-nicely.sh {checking} Type 'exit' to exit the ofbizDemo user and return to your normal user. {checking} Note: the notsoserial-1.0-SNAPSHOT.jar library is provided as an example, it might not be up to date.
