Problem with installation of NW 7.0 EHP3 (Linux + DB2)

Hello.

I am doing a fresh installation of NW 7.0 EHP3. Currently I am stuck at phase Import ABAP. I dont know how to fix this...

I've found this SNOTE that seems to be the exact problem:

https://launchpad.support.sap.com/#/notes/0001970577

"To perform the merge manually:

execute the following command in sapinst_instdir, where the TSK and TSK.bck files are existing, with <sid>adm user for every failed packages (TABART) separately:

on Windows: "R3load.exe -merge_only <SAPTABART>.TSK"
on Unix: "R3load -merge_only <SAPTABART>.TSK

or

to perform the merge by migration monitor automatically:

insert the parameter "-merge_bck" into migration monitor property file, if it was not set:

stop sapinst incl. migration monitor if it is was started manually
insert the R3load parameter "-merge_bck" into <export/import>_monitor_cmd.properties into the line: loadArgs=
like: loadArgs=-stop_on_error -merge_bck
restart sapinst incl. migration monitor if it is was started manually."

So tried both but none of that worked.

problem are 3 files

SAPNTAB.TSK
SAPSSEXC.TSK
SAPSPROT.TSK

manual merge:

> R3load -merge_only SAPNTAB.TSK
sapparam: sapargv(argc, argv) has not been called!

And same for

SAPSSEXC.TSK
SAPSPROT.TSK

I even edited import_monitor_cmd.properties according to "import_monitor_cmd.properties"

> cat import_monitor_cmd.properties
dbType=DB6
importDirs=/sapcommon/media/INEX_LOGO/export/51043228/DATA_UNITS/EXP1:/sapcommon/media/INEX_LOGO/export/51043228/DATA_UNITS/EXP2:/sapcommon/media/INEX_LOGO/export/51043228/DATA_UNITS/EXP3
installDir=/sapcommon/sapinst/LES/sapinst_instdir/NW703/AS-ABAP/DB6/CENTRAL

extFiles=no
dbCodepage=4103
jobNum=3
monitorTimeout=30
loadArgs=-stop_on_error -merge_bck -loadprocedure fast LOAD:COMPRESS_ALL:DEF_CRT
trace=all

Of course I've stopped SWPM while doing this.

When I run it again, I end with the same error...

And what's interesting is that when I check log files in the printscreen (import_monitor.log)

INFO: 2019-07-12 20:28:59

orderBy=
r3loadExe=/usr/sap/LES/SYS/exe/run/R3load
sapinst=
trace=all
tskFiles=yes

in loadArgs there is no "-merge_bck" even though I have eddited "import_monitor_cmd.properties" and put "-merge_bck" into "loadArgs" as described in SNOTE 1970577

this is from monitor_cmd.properties (just loadArgs listed here, rest of config is not interesting in this case I guess):

loadArgs=-stop_on_error -merge_bck -loadprocedure fast LOAD:COMPRESS_ALL:DEF_CRT

I would be glad for some tips.

Thank you.
