Oracle Solution for Error ora-09947

ORA-09947: Unable to allocate connection attributes structure

What triggered the Error:

ORACLE was not able to allocate the memory needed to hold the attributes of the SQL*Net connection. The "Additional Information" field holds the number of bytes that ORACLE attempted to allocate.

What should we do to fix it:

Check the UNIX error number. It is probable that the system has run out of memory. If there is no error, contact ORACLE customer support.
