But now it’s working. I had to change the HS_FDS_SHAREABLE_NAME in the initMSQLT.ora file:
set ODBCINI=/etc/unixODBC/odbc.ini
HS_FDS_CONNECT_INFO=MSQLT
HS_FDS_SHAREABLE_NAME = /usr/lib64/libodbc.so.2.0.0
HS_FDS_TRACE_LEVEL=0
HS_LANGUAGE = AMERICAN_AMERICA.WE8ISO8859P1
HS_NLS_NCHAR=UCS2
And in the odbc.ini there is no more a “Port”:
[MSQLT]
Description = MicrosoftSQL
Driver = /opt/microsoft/msodbcsql18/lib64/libmsodbcsql-18.3.so.2.1
Server = TCP:,1433
Database =
Encrypt = no
QuotedId = YES
AnsiNPW = YES
Threading = 1
UsageCount = 1

Hello Franco,
do you get an additional message after “Exiting hgolofns at 2024/01/24-14:37:30” in the trace file?
See e.g. My Oracle Support Note “DG4ODBC on Linux x86-64 Connecting to SQL*Server Gives ORA-28500 and Error in Trace – Failed to Load ODBC Library Symbol (Doc ID 1552081.1)” if you get an “Failed to load ODBC library symbol”.
Regards
Clemens

I’m trying on SUSE SLES 15 with Oracle 19.19 and I get an error in the trace of the Oracle ODBC:
Entered hgolofns at 2024/01/24-14:37:30
