WE are trying to create a DBLink from ADW to OCI DB but failed. We followed the following two documents:

2. How To Add A New Listener Entry With New Port to Default Listener in OCI DBSystem. (Doc ID 2603882.1) --> kindly note that this is sub document of the doc# 2592265.1
But we stuck on the following :
Step failed :
document # 2592265.1, section "Setup the DBLink from Autonomous (Serverless) to OCI DBSystem (Grid Infrastructure)" , sub-section "e) Create a DB Link from Autonomous Instance to Target Database" and step # 3.
3. Setting up authentication - Upload the target database wallet to the data_pump_dir directory on Autonomous Instance.
