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,

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).
