Hello,

I am performing a installation of NW PI 7.3 (ABAP+Java) with oracle 11.2 as the DB. the OS is Suse linux x86_64. I am facing this error in the initial stages. I am getting this error once after I select next in the screen where oracle listener related details are shown

the error is as shown below.
