For general recommendations, refer to Note 1962100.1 "Requirements for Installing Oracle 11.2.0.4 RDBMS on OL7 or RHEL7 64-bit (x86-64)" SCOPE  This document is intended to complement the official Oracle documentation. If there are any incompatibilities between this document and the official Oracle documentation, they are unintentional, and should be ignored. This document is not meant to be a substitute for official documentation; care should be taken to ensure that all official documentation is reviewed thoroughly. DETAILS  Operating System Installation & Setup - Recommendations Yum Repository Set up public-yum repository and enable the latest AddOns channels, e.g. # cat /etc/yum.repos.d/public-yum-ol7.repo [ol7_latest] name=Oracle Linux $releasever Latest ($basearch) baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL7/latest/$basearch/ gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle gpgcheck=1 enabled=1   [ol7_addons] name=Oracle Linux $releasever Add ons ($basearch) baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL7/addons/$basearch/ gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle gpgcheck=1 enabled=1 11gR2 preinstall RPM Install 11gR2 preinstall rpm. The preinstall rpm installs all dependencies for the Oracle RDBMS server installation, and creates the oracle user and the dba and oinstall groups.   Oracle ASMLib Download the certified oracleasmlib package from OTN (http://www.oracle.com/technetwork/server-storage/linux/asmlib/ol7-2352094.html) Install oracleasm packages if oracleasmlib is to be used yum install oracleasm-support.x86_64 oracleasmlib-2.0.8-2.el7.x86_64.rpm Oracle Automatic Storage Management Cluster File System (Oracle ACFS) For details on ACFS support, including required patches, refer to Note 1369107.1 (ACFS Support On OS Platforms (Certification Matrix)   Disk Naming Consistency For consistent disk naming, install device-mapper-multipath along with associated dependencies (device-mapper-multipath-libs.x86_64) yum install device-mapper-multipath     Multipathing Start multipathd, and verify status e.g. [root@xxxx ~]# systemctl start multipathd [root@xxxx ~]# systemctl status multipathd     SELinux Disable, e.g. setenforce 0     Oracle Grid Infrastructure - Installation Notes Patch 19404309 Note: It is presumed that the user has already reviewed the Oracle Grid Infrastructure Installation Guide and associated Release Notes; instructions and/or recommendations from those documents will not be repeated here.   After downloading the Oracle Grid Infrastructure software, and before attempting any installation, download Patch 19404309 from My Oracle Support, and apply the patch using the instructions in the patch README.   Patch 18370031 Download Patch 18370031 from My Oracle Support. Then, start an interactive Oracle Grid Infrastructure installation through the Oracle Universal Installer (OUI), but do notexecute root.sh on any node until afterthe application of Patch 18370031. When the OUI prompts the user to execute the root.sh scripts*, Patch 18370031 should be applied by following the instructions in Section 2.3, Case 5 - Patching a Software Only GI Home Installation or Before the GI Home Is Configured - of the patch README. Note: The README should be reviewed in full, as it contains other requirements (e.g. upgrading OPatch, etc.). * If executing a software-only installation, the patch should be applied after the installation concludes, but before any configuration is attempted. Once Patch 18370031 has been applied, proceed with the remainder of the installation (or configuration).     Oracle Database/RAC - Installation Notes Note: As the title suggests, this section applies both to installations of Oracle Database and Oracle Real Application Clusters (RAC).   Patch 19404309 Note: It is presumed that the user has already reviewed the Oracle Database, Oracle RAC Installation Guides and associated Release Notes; instructions and/or recommendations from those documents will not be repeated here.   After downloading the Oracle Database/RAC software, and before attempting any installation, download Patch 19404309 from My Oracle Support, and apply the patch using the instructions in the patch README.   Patch 19692824 During installation of Oracle Database or Oracle RAC on OL7, the following linking error may be encountered: Error in invoking target 'agent nmhs' of makefile '/sysman/lib/ins_emagent.mk'. See '' for details. If this error is encountered, the user should select Continue. Then, after the installation has completed, the user must download Patch 19692824 from My Oracle Support and apply it per the instructions included in the patch README.     Installation/Home Cloning Note: It may be possible to perform the above steps once, then use Oracle's cloning technology to clone the installation/home. Further details are available in the cloning sections of the relevant Administration and Deployment guides: Cloning Oracle Clusterware Cloning Oracle RAC to Nodes in a New Cluster Cloning Oracle Software REFERENCES NOTE:1369107.1 - ACFS Support On OS Platforms (Certification Matrix).
