If you add ECDA service information to a local sql.ini file, ECDA issues this error message during start-up:
CT-LIBRARY error: ct_connect(): directory service layer: internal directory control layer error: Requested server name not found.
You must add ECDA service information to the global sql.ini file instead of the local sql.ini file.
The global sql.ini file is located in <install_dir>\ini\sql.ini. The local sql.ini file is located in <install_dir>\DC-15_0\connectivity}\ini\sql.ini.
