IBM AppConnect Enterprise 11 on Linux - reminding myself

I was having a chat with a colleague about the merits of running the IBM AppConnect Enterprise (ACE) or IBM Integration Bus (IIB) Toolkit on a Linux VM.

So, to remind myself, I spun up an existing RHEL 7.4 VM, and installed the required GUI-related RPMs: -

yum install -y  xterm
yum install -y  gtk2
yum install -y  libgtk-x11-2.0.so.0
yum install -y  libXtst
yum install -y  xeyes
yum install -y  xauth
yum install -y  xorg-x11-fonts-Type1
yum install -y  psmisc


and then switched to the ACE user: -

su - aceadmin

and started the Toolkit: -

/opt/ibm/ace-11.0.0.0/tools/eclipse 

Alas this failed: -

Eclipse:
An error has occurred. See the log file
/home/aceadmin/IBM/ACET11-config/11.0.0.0/configuration/1526978110847.log.

so I checked the log: -

cat /home/aceadmin/IBM/ACET11-config/11.0.0.0/configuration/1526978110847.log

Before panicking, I checked my flow - I'd logged into the VM as root: -

ssh -Y root@integration

and then switched to the aceadmin user.

Therefore, the X11 session was "owned" by root rather than aceadmin.,

I logged out, and reconnected: -

ssh -Y aceadmin@integration

and retried: -

/opt/ibm/ace-11.0.0.0/tools/eclipse 


Nice :-)
