Make sure the OLEDB driver you want to use is installed.

Have you installed the Drivers in the QV server ?? Try to open the File in server and check the connection once

I have installed Oracle Client in the server and it works when reloading manually.

Please tell me where can I check whether I have installed OLEDB Driver

It works fine when reloading manually. But showing this error when reloading through publisher

[avinashelite]

Have you opened the file with >open in server option from File?? If you have installed the Driver locally it work fine in local QV but not in server

I have installed oracle client in the server where qlikview server is installed and also I am trying to reload manually from the same server. It works fine there

Issue is fixed now.

I was using QDS Cluster and in the cluster machine Drivers were not installed.

After installing it worked fine.
