"TNS:connect descriptor is too long"
*Cause: The connect descriptor corresponding to the net service name
specified as the connect identifier is too long. The maximum length for
a connect descriptor is 512 bytes and this limit has been exceeded.
*Action: Check the net service name's connect descriptor in the local
naming file (TNSNAMES.ORA) or in the directory server (Oracle Internet
Directory). Use a smaller connect descriptor. If this is not possible,
contact Worldwide Customer Support.
