How I Simplified Oracle Database 12c and 11g Installations on Oracle Linux 6

by Ginny Henningsen; updated by Michele Casey

How to simplify the installation of Oracle Database 12c or 11g on Oracle Linux 6 by installing the oracle-rdbms-server-12cR1-preinstall or oracle-rdbms-server-11gR2-preinstall RPM package, which automatically performs a number of tasks, such as installing required software packages, resolving package dependencies, and modifying kernel parameters.

READ THIS FIRST: Important Changes Since Publication

While the content in this article is still valid, several details have changed.  For example:

  • For Oracle Database 12c Release 2, the preinstall RPM has a different name than the one used in the article belowpu:
    • oracle-database-server-12cR2-preinstall
    • See also this documentation: Automatically Configuring Oracle Linux with Oracle Preinstallation RPM
  • The preinstall RPMs are published on Oracle Linux yum server for both Oracle Linux 6 and 7 in the Latest repositories which are configured and enabled by default in recent releases of Oracle Linux 6 and 7 


 

Introducing the oracle-rdbms-server-12cR1-preinstall and oracle-rdbms-server-11gR2-preinstall RPM for Oracle Linux

Before installing Oracle Database 12c or 11g on a system, you need to preconfigure the operating environment since the database requires certain software packages, package versions, and tweaks to kernel parameters. (Be sure to review the appropriate Oracle Database installation guide to familiarize yourself with hardware, software, and operating system requirements.)

Note: This article applies to Oracle Linux 6. A previous article, "How I Simplified Oracle Database Installation on Oracle Linux," covered performing a similar task on versions of Oracle Linux 5.

On Oracle Linux, I discovered that there is a remarkably easy way to address these installation prerequisites: First, depending on your database version, install either the RPM package called oracle-rdbms-server-12cR1-preinstall or oracle-rdbms-server-11gR2-preinstall. This RPM performs a number of preconfiguration steps, including the following:

  • Automatically downloading and installing any additional software packages and specific package versions needed for installing Oracle Grid Infrastructure and Oracle Database 12 c Release 1 (12.1) or 11g Release 2 (11.2.0.3), with package dependencies resolved via yum or up2date capabilities.
  • Creating the user oracle and the groups oinstall (for OraInventory) and dba (for OSDBA), which are used during database installation. (For security purposes, this user has no password by default and cannot log in remotely. To enable remote login, please set a password using the passwd tool.)
  • Modifying kernel parameters in /etc/sysctl.conf to change settings for shared memory, semaphores, the maximum number of file descriptors, and so on.
  • Setting hard and soft shell resource limits in /etc/security/limits.conf, such as the locked-in memory address space, the number of open files, the number of processes, and core file size.
  • Setting numa=off in the kernel for x86_64 machines.

Note that oracle-rdbms-server-12cR1-preinstall and oracle-rdbms-server-11gR2-preinstall parses the existing /etc/sysctl.conf and /etc/security/limits.conf files and updates values only as needed for database installation. Any precustomized settings not related to database installation are left as is.

The oracle-rdbms-server-12cR1-preinstall and oracle-rdbms-server-11gR2-preinstall RPM packages are accessible through the Oracle Unbreakable Linux Network (ULN, which requires a support contract), from the Oracle Linux distribution media, or from the Oracle public yum repository. Thus, whether or not your system is registered with ULN to access Oracle patches and support, you can use oracle-rdbms-server-12cR1-preinstall and oracle-rdbms-server-11gR2-preinstall to simplify database installation on Oracle Linux. In addition, the Oracle public yum repository now includes all security and bug errata, ensuring systems are secured and stable with the latest security updates and bug fixes.

Installing the oracle-rdbms-server-12cR1-preinstall or oracle-rdbms-server-11gR2-preinstall RPM

The remainder of this article steps through the procedure that I used for installing oracle-rdbms-server-11gR2-preinstall on Oracle Linux via the Oracle public yum repository. The same steps outlined in the following section can be used for either version of the preinstall RPM package. I started with a system running Oracle Linux Release 6 Update 4 for x86_64, a 64-bit version of Oracle Linux that I downloaded from the Oracle software delivery cloud (requires registration or login). First, I set up a yum configuration file that pointed to the correct repository, and then I installed the oracle-rdbms-server-11gR2-preinstall RPM from that repository.

Here are the steps for preconfiguring a system for Oracle Database installation using oracle-rdbms-server-11gR2-preinstall. Remember, the steps are the same when using the oracle-rdbms-server-12cR1-preinstall package; you simply need to change the name of the RPM package during the yum installation step.

  1. As an authorized user (for example, root), retrieve the file that configures repository locations:
      
    # cd /etc/yum.repos.d

# wget http://yum.oracle.com/public-yum-ol6.repo
  2. Using a text editor, modify the file, changing the field enabled=0 to enabled=1 to reflect repositories that correspond to the machine''s operating system release.
     

    Here is an excerpt of public-yum-old6.repo with the changed lines in boldface.

    [ol6_latest]

name=Oracle Linux $releasever Latest ($basearch)

baseurl=http://yum.oracle.com/repo/OracleLinux/OL6/latest/$basearch/

gpgkey=http://yum.oracle.com/RPM-GPG-KEY-oracle-ol6

gpgcheck=1

enabled=1





[ol6_UEK_latest]

name=Latest Unbreakable Enterprise Kernel for Oracle Linux $releasever ($basearch)

baseurl=http://yum.oracle.com/repo/OracleLinux/OL6/UEK/latest/$basearch/

gpgkey=http://yum.oracle.com/RPM-GPG-KEY-oracle-ol6

gpgcheck=1

enabled=1
     

    Because the target system is running Oracle Linux Release 6 Update 4 for x86_64, which installs the Oracle Unbreakable Enterprise Kernel by default, there are two repositories to enable, [ol6_latest] and [ol6_UEK_latest].

  3. Next, install the oracle-rdbms-server-11gR2-preinstall RPM using the yum install command. If you are using Oracle Database 12c, then you would type yum install.
     

    The output in Listing 1 shows how the installation checks dependencies and then downloads and installs the required packages.

    # yum install oracle-rdbms-server-11gR2-preinstall

    Listing 1: Installing the oracle-rdbms-server-11gR2-preinstall RPM

    The yum installation logs messages about kernel changes in the file /var/log/oracle-rdbms-server-11gR2-preinstall/results/orakernel.log, and it makes backups of current system settings in the directory /var/log/oracle-rdbms-server-11gR2-preinstall/backup.

  4. At this point, the system is ready for the installation of Oracle Database. For example, to install Oracle Database 11g Release 2, follow the directions in Chapter 4, "Installing Oracle Database," of the Database Installation Guide for Linux."
     

    Here are the steps I followed while installing Oracle Database 11g Release 2 in my test environment. Make sure you review all documentation and follow recommended best practices before installing into your production environment.

    1. As root, create a parent directory in a file system that has sufficient space to be the target location for the downloaded files:
        
      # mkdir /home/OraDB11g

# cd /home/OraDB11g
       

      The amount of disk space needed in the file system varies according to the specific installation type, but roughly twice the size of the zip archives, or 5 GB, is enough to house the software and data files.

    2. Into this target directory, download the installation media files from the Oracle Database Software Downloads page on Oracle Technology Network.
    3. Extract the files:
        
      # unzip linux.x64_11gR2_database_1of2.zip

# unzip linux.x64_11gR2_database_2of2.zip
    4. Log in as the user oracle. Change directory to the database directory and enter the following command to run the Oracle Universal Installer:
        
      $ cd /home/OraDB11g/database

$ ./runInstaller

    The Oracle Universal Installer performs a number of checks, verifying that the necessary OS packages and versions are installed. In addition, it checks kernel parameters set by the oracle-rdbms-server-11gR2-preinstall installation. During the kernel settings check, the installer might flag a few settings as "failed," and you should investigate these failures. In some cases, you still might be able to continue with the database installation. If you check kernel settings in /etc/sysctl.conf, you''ll see that oracle-rdbms-server-11gR2-preinstall has modified and added the necessary settings to ensure the minimum requirements are met, as defined in section 2.10.1, "Displaying and Changing Kernel Parameter Values," in Chapter 2, "Oracle Database Preinstallation Requirements," of the Oracle Database Installation Guide 11g Release2 (11.2) for Linux. Below is the list of requirements:

    fs.aio-max-nr = 1048576

fs.file-max = 6815744

kernel.shmall = 2097152

kernel.shmmax = 4294967295

kernel.shmmni = 4096

kernel.sem = 250 32000 100 128

net.ipv4.ip_local_port_range = 9000 65500

net.core.rmem_default = 262144

net.core.rmem_max = 4194304

net.core.wmem_default = 262144

net.core.wmem_max = 1048576
     

    If necessary, you can (as root) edit the file /etc/sysctl.conf to specify a setting manually, for example:

    # vi /etc/sysctl.conf 

# /sbin/sysctl -p
     

    The Oracle Universal Installer performs additional checks, such as verifying the glibc version, sufficient disk space, environmental variable and path settings, and sufficient physical memory and swap space. Generally, installing oracle-rdbms-server-11gR2-preinstall takes care of the prerequisites so that you can proceed directly with installing the database.

Final Thoughts

Installing the oracle-rdbms-server-12cR1-preinstall and oracle-rdbms-server-11gR2-preinstall RPMs can save time when installing Oracle Database 12c and 11g on Oracle Linux. These RPMs address most Oracle Database installation prerequisites and greatly simplify the installation process.

Install Oracle 11G Release 2 (11.2) on Oracle Linux 7 (OEL7)

Posted on May 3,2014

This article presents how to install Oracle 11G on Oracle Enterprise Linux 7 (OEL7).

Read following article how to install Oracle Enterprise Linux 7: Install Oracle Linux 7 (OEL7) (for comfort set 2G memory for your virtual machine before proceeding with Oracle software installation).

Installation software is available on OTN version 11.2.0.1 or Metalink 11.2.0.4. In this installation I’m presenting installation for 11.2.0.4 but for prevIoUs version 11.2.0.X it shouldn’t be different.

Oracle software which I verified

release 11.2.0.4

@H_301_22@p13390677_112040_Linux-x86-64_1of7.zip p13390677_112040_Linux-x86-64_2of7.zip

OS configuration and preparation

OS configuration is executed as root. To login as root just execute following command in terminal.

@H_301_22@su - root

Add groups

@H_301_22@--required groups /usr/sbin/groupadd -g 501 oinstall /usr/sbin/groupadd -g 502 dba /usr/sbin/groupadd -g 503 oper
Add user Oracle
@H_301_22@/usr/sbin/useradd -u 502 -g oinstall -G dba,oper oracle

Change password for user

@H_301_22@passwd oracle
Add kernel parameters to /etc/sysctl.conf
@H_301_22@kernel.shmmni = 4096 kernel.shmmax = 4398046511104 kernel.shmall = 1073741824 kernel.sem = 250 32000 100 128 fs.aio-max-nr = 1048576 fs.file-max = 6815744 net.ipv4.ip_local_port_range = 9000 65500 net.core.rmem_default = 262144 net.core.rmem_max = 4194304 net.core.wmem_default = 262144 net.core.wmem_max = 1048586

Apply kernel parameters

@H_301_22@/sbin/sysctl -p

Add following lines to set shell limits for user oracle in file /etc/security/limits.conf

@H_301_22@oracle soft nproc 131072 oracle hard nproc 131072 oracle soft nofile 131072 oracle hard nofile 131072 oracle soft core unlimited oracle hard core unlimited oracle soft memlock 50000000 oracle hard memlock 50000000

The “/etc/hosts” file must contain a fully qualified name for the server.

@H_301_22@<IP-address> <fully-qualified-machine-name> <machine-name>

For example.

@H_301_22@127.0.0.1 oel7 oel7.dbaora.com localhost localhost.localdomain

Modify .bash_profile for user oracle in his home directory

@H_301_22@# Oracle Settings export TMP=/tmp export ORACLE_HOSTNAME=oel7.dbaora.com export ORACLE_UNQNAME=ORA11G export ORACLE_BASE=/ora01/app/oracle export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1 export ORACLE_SID=ORA11G PATH=/usr/sbin:$PATH:$ORACLE_HOME/bin export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export CLAsspATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; alias cdob='cd $ORACLE_BASE' alias cdoh='cd $ORACLE_HOME' alias tns='cd $ORACLE_HOME/network/admin' alias envo='env | grep ORACLE' umask 022

Check which packages are installed and which are missing

@H_301_22@rpm -q --qf '%{NAME}-%{VERSION}-%{RELEASE}(%{ARCH})\n' binutils \ elfutils-libelf \ elfutils-libelf-devel \ gcc \ gcc-c++ \ glibc \ glibc-common \ glibc-devel \ glibc-headers \ ksh \ libaio \ libaio-devel \ libgcc \ libstdc++ \ libstdc++-devel \ make \ sysstat \ unixODBC \ unixODBC-devel

In my case it returns following

@H_301_22@binutils-2.23.52.0.1-12.el7(x86_64) elfutils-libelf-0.157-2.el7(x86_64) package elfutils-libelf-devel is not installed gcc-4.8.2-3.el7(x86_64) gcc-c++-4.8.2-3.el7(x86_64) glibc-2.17-36.el7(x86_64) glibc-common-2.17-36.el7(x86_64) glibc-devel-2.17-36.el7(x86_64) glibc-headers-2.17-36.el7(x86_64) package ksh is not installed libaio-0.3.109-9.el7(x86_64) package libaio-devel is not installed libgcc-4.8.2-3.el7(x86_64) libstdc++-4.8.2-3.el7(x86_64) libstdc++-devel-4.8.2-3.el7(x86_64) make-3.82-19.el7(x86_64) sysstat-10.1.5-1.el7(x86_64) package unixODBC is not installed package unixODBC-devel is not installed

There are two options to install missing packages

  • You need to install missing from dvd. Just mount it and install missing packages using rpm -Uvh command from directory <mount dvd>/Packages.

NOTE – I’m using x86_64 version of packages

@H_301_22@rpm -Uvh elfutils-libelf-devel*.x86_64.rpm rpm -Uvh libaio-devel*.x86_64.rpm rpm -Uvh unixODBC*.x86_64.rpm rpm -Uvh ksh*.x86_64.rpm
  • Run yum install command for missing packages
@H_301_22@--example howto install many packages yum install elfutils-libelf-devel \ ksh \ libaio-devel \ unixODBC*

Create directory structure for database software

  • ORACLE_BASE – /ora01/app/oracle
  • ORACLE_HOME – /ora01/app/oracle/product/11.2.0/db_1
@H_301_22@mkdir -p /ora01/app/oracle/product/11.2.0/db_1 chown oracle:oinstall -R /ora01

disable secure linux by editing the “/etc/selinux/config” file,making sure the SELINUX flag is set as follows. It requires REBOOT to be effective !!!

@H_301_22@SELINUX=permissive

In Oracle Enterprise Linux 7 /tmp data is stored on tmpfs which consumes memory and is too small. To revert it back to storage just run following command and REBOOT machine to be effective.

@H_301_22@systemctl mask tmp.mount

Install database software

Let’s start with database software installation as oracle user.

@H_301_22@su - oracle --unzip software 11.2.0.4 unzip p13390677_112040_Linux-x86-64_1of7.zip unzip p13390677_112040_Linux-x86-64_2of7.zip --I defined 4 aliases in .bash_profile of user oracle to make --administration heaven :) [oracle@oel7 ~]$ alias envo cdob cdoh tns alias envo='env | grep ORACLE' alias cdob='cd $ORACLE_BASE' alias cdoh='cd $ORACLE_HOME' alias tns='cd $ORACLE_HOME/network/admin' --run alias command envo to display environment settings envo ORACLE_UNQNAME=ORA11G ORACLE_SID=ORA11G ORACLE_BASE=/ora01/app/oracle ORACLE_HOSTNAME=oel7.dbaora.com ORACLE_HOME=/ora01/app/oracle/product/11.2.0/db_1 --run alias command cdob and cdoh to check ORACLE_BASE,ORACLE_HOME [oracle@oel7 ~]$ cdob [oracle@oel7 oracle]$ pwd /ora01/app/oracle [oracle@oel7 db_1]$ cdoh [oracle@oel7 db_1]$ pwd /ora01/app/oracle/product/11.2.0/db_1 --run installation ./runInstall
