Docker installation of "AS ABAP 7.52 SP04" hangs

[abo]

Hi.

On a base Debian/testing system, I have downloaded 7.52 SP04 and verified the checksum of all parts, so far so good.

Starting from an empty /var/lib/docker and with dockerd stopped, I added the following /etc/docker/daemon.json:

{ "storage-opt": [ "dm.basesize=60G" ] }   

Additionally, I have executed:

sudo sysctl -w vm.max_map_count=1000000

After that, I started Docker 19.03.13 and verified that it worked with the hello-world example.

With regards to NW,I have found, and tried, a number of slightly different Dockerfiles

• https://github.com/nzamani/sap-nw-abap-trial-docker
• https://github.com/tobiashofmann/sap-nw-abap-docker
• https://github.com/marcellourbani/abap_trial_docker

but they all hang at the same point and this is the last message I see:

INFO       2020-11-08 14:17:52.945 (root/sapinst) (startInstallation) [iaxxbfile.cpp:594] id=syslib.filesystem.aclSetSucceeded CIaOsFile::chmod_impl(3,0755)

Authorizations set for /sybase/NPL/startase_reset_sa.

At this point, activity appears to stall: CPU load drops to idle and there is no noticeable disk activity. The docker partition only occupies 24% of about 160GB. This happens also without the daemon.json, again starting from scratch.

If I run strace against "sh /sybase/NPL/startase_reset_sa", I see it is stuck waiting for the child process, which is /sybase/NPL/ASE-16_0/bin/dataserver.

Questions:

• Has anyone else met with this or a similar problem?
• Is Docker a supported installation method? Or should I, say, try VirtualBox?

Thanks,

Andrea.

Andrea,

I don't know what your problem is but looks kind of similar to the one I have, where the database silently fails, leaving only an error in a log file (don't have a copy available, should spin up a new container)

Weirdly, on a laptop is working fine, on the other worked for a year or so then dies a few months ago.

The error is in file

/sybase/NPL/ASE-16_0/install/NPL.log, about 30 lines before the end

Not sure what to make of it, though.

...or save even more with Alexander Tsybulsky's vagrant script

PS: docker uses a lot less memory (say 1.5 Gb vs ~6), not a bad idea when it works out of the box. When it doesn't can be pretty tough

[abo]

By all means, just be prepared to quickly fall back to the official guide if things don't work as expected.

I stumbled upon your post after running into the same problem. Do you by any chance remember how much RAM had the host (not guest VM) you tried this on? Having found SIGSEGV in the logs, my only guess is that this could be memory-related - it looks like the database server is trying to come up for the first time around that point in time of the installation. FWIW, I was trying this (Docker in Ubuntu) on the host with 8GB RAM and that might be too low. I was successful after installing this in vanilla openSUSE WSL2 instance (without Docker) with 16GB host RAM.

[abo]

The host has 16GB of RAM so I don't think this was a low-mem issue: with Virtualbox runs just fine in 6GB max.

Former Member interesting finding! I'm not sure what kernel version I had back then but right now I have 5.10.x, which seems to be fine as far as HANA 1909 is concerned. True, I did not have to build that image, SAP did that.

[Former Member]

Hi Andrea,

the kernel is yours, as it comes actually with the Linux distribution. Today I was bored and decided to try the 1909 Trial. Installed it on Docker/WSL2. My first Docker experience, and WSL, too. Yes HANA is happy with newer kernels, opposite to ASE.

vhcala4hci:/ # uname -r
5.4.72-microsoft-standard-WSL2

Former Member

I know, I know. What I meant is that I did not think of writing the kernel version in the question and now so much time has passed that I'd have to spend even more time finding out which version I likely had back then.

murbani

Which version do you have in your image? If it's older than 5.4.x I guess Robert's comment should be promoted to answer.

[MarcelloUrbani]

Agreed

I'm on a rolling distribution, I update my kernel weekly

Dates make sense

I think it's still working on my older computer though, so might be hardware dependent

[abo]

Former Member please convert your comment on kernel versions to answer, I'll accept that one instead of mine.

[Former Member]

Thank you Andrea. Comment is converted.
