I have problem reloading files from reload engine. I have a 64 Bit machine running Windows Server 2008 R2 Standard. My backend database server is Oracle which is a 32 Bit installation. I have both Qlikview developer and Qlikview server 32 Bit installations.
Now when I reload files individually it extracts data from the database properly. But when I try to reload the document from Reload Engine it give the following error...
Is it possible that your QVS is actually 64-bit (this would make since due to the advantages of 64-bit QVS over 32-bit QVS)? If so, then the 64-bit QVS can't 'see' the 32-bit Oracle drivers. Your 32-bit QV Developer can, however. Our system is 64-bit everything. QVS, QVP, and all drivers (like Oracle) -- all 64-bit. We had a problem with MS Access a few years back because until Office 2010 Microsoft didn't make a 64-bit driver for Access. Since our QVP/QVS was 64-bit would couldn't use the 32-bit Access driver. It was quite a pain (luckly we didn't need to use Access as a data source).
I did as you said but it won't show the drivers list in the ODBCAD32.exe menu. I just worked around with this issue. I downloaded an ODAC from Oracle site which provided me with OLE DB drivers. I installed it and then in the Qlikview file I selected source as an OLE DB with force 32 Bit option. Then I tried to reload via Reload Engine and it worked. Maybe theres some compatibility issues with ODBC drivers on my system.
