Rapid SQL/Sybase Open Client 15 Error: "Unable to find an available protocol driver structure"
原标题:

All,

After several months of not touching our databases I fired up Rapid SQL and get this error when I try and connect to a registered Sybase DB:

"Layer (5) Origin (3), Severity (5), Number (3) ct_connect(): network_packet_layer: internal net library error: Unable to find an available protocol driver structure"

Any ideas? I m running on a corporate desktop build so always possible that drivers and software are changed/installed etc every time I log on.

Thanks in advance

  1. Ensure that the Sybase System/Environment variable points to the latest version of sybase.
  2. Rename an old Sybase installs to Old-Sybase12 etc.
  3. Remove any old Sybase directories from your path.
  4. Make sure your path contains the latest Sybase dirs.

Should do it.
