Summary :
This SAP Note explains the necessity of setting the NOEXEC_USER_STACK kernel parameter to 1 for Oracle installations on Solaris systems. This setting prevents execution on the user stack, enhancing security by making buffer-overflow attacks more challenging. Applicable for Solaris 9 and 10, it ensures that 32-bit applications obtain the same security protections as 64-bit applications on systems with suitable hardware. The note references Oracle Installation Guides for detailed instructions and stresses that this configuration modulates stack execution capabilities without influencing SGA size, exclusively for security enhancement purposes.
