The setting
for the RMEM_MAX (net.core.rmem_max) parameter is required during
database installation. Once installation is complete it is still
advisable to set the parameter as recommended to avoid impacting
database performance and overall functionality, as well as unexpected
operating system behavior.
Set the RMEM_MAX (net.core.rmem_max) kernel parameter greater than or equal to the minimum recommended value. RMEM_MAX defines the TCP Window. See Document 169706.1 for more information about the proper setting for the platform and Oracle version. To modify the parameter use any text editor to create or edit the /etc/sysctl.conf file and add or edit a line similar to the following: net.core.rmem_max = 2097152. The new value will take effect after reboot.
