ORA-09947

Unable to allocate connection attributes structure

Cause

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.


Action

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.
