Catherine,
This error indicates that the Java code that the OTM script runs is not able to make a connection with the database server. This code is used to update the OTM DB content from CSV files.
This error could be caused by:
- Incorrect DB parameters entered during the OTM installation, including hostname, port and/or SID. These are located in D:\otm55\glog\config\glog.properties
- The Oracle DB is not running
- A firewall is between the OTM App and DB server, which is blocking the traffic
