JCO Connectivity issue 32bit vs 64bit vs 32bit

100 Views

Hi,

we are running IDM 8.0 with latest SPs. Now, trying to connect an ABAP system runs into connection error "Parameter message server host ('jco.client.mshost') is missing" although all parameters are correctly set. So after some investigation and checking some SAP notes I tried to check the installed JCo version (system was installed & updated using SWPM/SUM). The console showed Java VM version and JCo3 API. But library could not be found. Instead there was an error "Can't load AMD 64-bit .dll on a IA 32-bit platform".

Ok... so, following note 2313331 I replaced the JCo3 files with the 32 bit version, re-started everything and checked again the JCo console. Now, it's fine - no errors, library was loaded, initialization successfully.

Great, I thought, problem solved, I thought... Nope.. the connection test to ABAP repository still failed. I increased the trace level and checked the DSE.log file. Now, here comes the funny part... it says "Can't load IA 32-bit .dll on a AMD 64-bit platform" (>_<)

Anyone, knows this stupid behavior?

Regards, Richard
