Error "can not copy the lexicon" during installation

[gregorw]

Hello TREX Experts,

I have my NetWeaver ABAP 7.52 Developer Edition running in a Ubuntu 16.04.5 LTS using Vagrant with this script: https://github.com/sbcgua/sap-nw-abap-vagrant. From the SAP Service Marketplace I've downloaded TREX 7.10: Revision 77 and I've also tried Revision 76. But in both cases I face the same issue during installation.

As a pre-requisite I've installed libstdc++6 and linked it to the position where the TREX installer expects it. Then I could start the installation:

sudo apt-get install libstdc++6
sudo su -
ln -s /usr/lib/x86_64-linux-gnu/libstdc++.so.6 /usr/lib64/libstdc++.so.6
./install.sh --action=install --sid=TRX --instance=10 --target=/sybase

That is the relevant output when the installation get's stuck:

Installing new version 7.10.76.404644, creating link: TREX_7.10.76.404644 -> /sybase/TRX/exe/nuc/linuxx86_64/trex_new

Hope that anyone can help me with that unsupported installation.

Hi Gregor,

I haven't used TREX in ubuntu but I would suggest the errors point to sapinit. Ubuntu does not have the chkconfig command which prevents sapinit install.

I would suggest commenting out the chkconfig lines in installsapinit.sh script in the install directory "support/installsapinit.sh" or replace/add a line with

systemctl enable ${SAPINIT}

However.

Before installing again, also link sh to bash and not dash as most likely the case in Ubuntu and try again

/bin/sh -> /bin/bash

**even if the above gets past the error - not sure TREX will work on unsupported O/S**

Regards

Robert

Thank you Robert, that brought me one step closer to a solution. I was able to finish the installation. At the first start the start failed do to the command lockfile not found. After installing:

sudo apt-get install procmail

The start continues further but now I get the following error in /usr/sap/TRX/TRX10/vhcalnplci/trace/TrexDaemon_vhcalnplci.00000.000.trc:

Perhaps you have some more tips.

Hi Gregor,

With that memory error, if you haven't done so already, I would validate the overall memory allocation of the 7.52 ABAP system + TREX

Check the link for the sappfpar checks to check minimum and worst case memory allocation for 7.52 and required swap.

As TREX will most likely want 1gb of memory set in sapprofile.ini it then depends on your setup. If it's possible to allocate more memory to your VM/server or reduce the ABAP 7.52 memory allocation (reduce PHYS_MEMSIZE ) . (If you have enough memory, then I would be stuck at that point.)

Regards

Robert

Thank you Robet. I've assigned now 6GB to the VM and adjusted the kernel.shmmax parameter according to Linux Kernel Parameters. But I've used 2147483648 (2GB).
