SapDB 7.4 ODBC connection from a MAXDB driver

197 Views

Hi all,

on a linux machine I have to connect to a Sapdb 7_4_3_35 database via unixODBC and python.

On the machine is the a database instance running with MaxDB 7_7_07_16.

The related ODBC driver is also installed. When trying to connect to the 7.4 instance I get an error like

[unixODBC][SAP AG][LIBSDBOD SO][MaxDB] Communication link failure;

-10709 Connection failed (RTE:database not running: no request pipe) (-10709) (SQLDriverConnectW)'

I thought now why not install the sapdb ODBC driver.

On different machines this is no problem but not on this one.

The installation breaks after executing ./SDBINST with a message that the downgrade is not possible:

2: ODBC

3: Server

4: Runtime For SAP AS

5: all

6: none

please enter profile id: 2

starting preparing phase of package Base 7.4.03.35 32 bit

cannot downgrade package

skipping package

Is there a solution available to connect to both database versions?

I would be thankful for help.

Regards
