data service job failed on second node.

Hi Experts,

We have installed IPS(4.0) & DATA SERVICE 4.1 in two different node for load balancing or cluster. In first node jobs are running succesfully but in the second node it gets failed with the below error:-

CON-120404: Initialization oci call <ociEnvcreate > for connection <sid> failed :<data repository>.

but the same job is runing successfully in the 1st node.We have installed oracle full client in both the node.

Kindly suggest.
