Appendix A: Revision History Revision 1.0 Friday February 28, 2014 Roger Lopez Initial Release Revision 1.1 Friday February 13, 2015 Roger Lopez - Updated version of installed Oracle database and Oracle Grid Infrastructure to 12.1.0.2.0 - Added note to set NOZEROCONF to yes in Section 3.1 Setting OS Hostname - Added new kernel parameter requirement: kernel.panic_on_oops = 1. It is set to 1 by default on RHEL 6.5, but the Oracle Installer requires it to be set in /etc/sysctl.conf to pass the prerequisite checks. Section 3.3.13 Kernel Panic On OOPS Parameter shows the details. - Changed recommendation to always create partitions when using either Oracle ASMLib or udev rules in Section 3.4.2 Partitioning Device Mapper Shared Disks - Moved NTP configuration under Section 3.3 OS Configuration - Removed from Appendix C the duplicate 'defaults' entry in /etc/mutlipath.conf . - The value of swappiness is changed from the value of 0 to the value of 1 for RHEL 6.4 or higher due to the increase risk of a system OOM killing. Bugzillas for more information: & - Created a custom oracle tuned profile better suited than the existing enterprise-storage-no- thp profile within Section 3.4.4 Optimizing Database Storage using Automatic System Tuning - Created a 98-oracle.conf file that sets all the kernel parameters if not using the oracle tuned profile. File should be placed in /etc/sysctl.d - New Section 6 Post Installation Cleanup Tasks that removes setting oracle kernel parameters from /etc/sysctl.conf once installation is complete and using either the oracle tuned profile or the 98-oracle.conf to properly set those parameters. - Added Appendix L Custom Oracle Tuned Profile Scripts section that includes the Oracle custom profile scripts Revision 1.2 Tuesday, March 10, 2015 Roger Lopez - Updated Section 3.4.4 Optimizing Database Storage using Automatic System Tuning by changing the oracle custom profile to be based off the throughput-performance profile instead of the enterprise-storage profile. Doing so, provides consistency of the profile for both RHEL6 and RHEL7 deployments. - The .tar.gz oracle custom oracle profile was modified to be based off the throughput- performance profile and documented within the CHANGELOG [email protected] 71
