Oracle Error ORA-09947: Unable to allocate connection attributes structure

Oracle Error Message

ORA-09947: Unable to allocate connection attributes structure

Reason for 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.

Solution

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.
