I have remote server and access through oracle client and dbartisan.I do have resource and connect privileges.When I am exporting tables from my schema this problem is encountered(ora-12560: TNSrotocol adapter error).I did look into TNSnames.ora file on my computer , which already contains the name of the database I am trying to export from.

Could not understand why ?? I would appreciate if someone could answer to this.where further I should look into.
