If you have Solaris kernel options on your system, I hope this guide will help you.

These concepts explain how to tweak kernel options issued for Oracle Solaris if you can’t extend them with patch scripts.

Minimum settings for installation
Use the table of elements to define settings manually if the user cannot use scripts to fixeniya.

Check shared memory resource controls
Use the prctl command to query and make changes at run time: Resource controls associated with a process, task, or booming project throughout the system are linked.

Displaying and changing kernel parameter values
Why? Use these procedures to display the current value visible to resource controls and change each one as needed:

Configuring UDP and TCP Kernel Settings Manually
If you are not using their patch script or CVU to manage ephemeral ports, set the TCP/IP distance settings for ephemeral ports to have enough ephemeral ports to handle the expected server load.

The following is a list of most Solaris kernel options that must be packaged prior to installing Oracle on Solaris. In each of our previous articles, we have talked about the parameter x Linux kernel for Oracle.

How do I change the kernel parameters in Solaris 11?

To change a kernel option, create an entry in /etc/sysctl. conf or is it really worth changing the current entry. If the parameter value is not present in the /etc/sysctl. conf for your setup uses the default performance system.
