This chapter describes the tasks that you must complete before you start Oracle Universal Installer.
Note:
To use Oracle Automatic Storage Management (Oracle ASM) or Oracle Restart, you must first install Oracle Grid Infrastructure for a standalone server before you install and create the database. Otherwise, you must manually register the database with Oracle Restart.See Also:
"Configuring Servers for Oracle Grid Infrastructure for a Standalone Server" before you proceed with the database preinstallation tasks
Chapter 4, "Configuring Users, Groups and Environments for Oracle Database"
This chapter includes information about the following topics:

During installation, you must perform tasks as root or as other users on remote terminals. Complete the following procedure for user accounts that you want to enable for remote display.
Note:
If you log in as another user (for example,grid), then repeat this procedure for that user as well.To log in as the root user and enable remote display, complete one of the following procedures:
If you are installing the software from an X Window System workstation or X terminal, then:
Start a new X terminal session (xterm).
If you are installing the software on another system and using the system as an X11 display, then enter a command using the following syntax to enable remote hosts to display X applications on the local X server:
$ xhost + RemoteHost
where RemoteHost is the fully qualified remote host name. For example:
$ xhost + somehost.example.com
somehost.example.com being added to the access control list
If you are not installing the software on the local system, then use the ssh, rlogin, or telnet command to connect to the system where you want to install the software:
$ ssh -Y RemoteHost
If you are not logged in as the root user, then enter the following command to switch the user to root:
$ sudo sh password: #
To install the software from a PC or other system with X server software:
Note:
If necessary, see the X server documentation, or contact your X server vendor or system administrator for more information about completing this procedure. Depending on the X server software that you are using, you may have to complete the tasks in a different order.Start the X Window System software.
Configure the security settings of the X Window System software to permit remote hosts to display X applications on the local system.
Connect to the remote system where you want to install the software as the oracle software installation owner (oracle) and start an X terminal session (xterm) on that system.
Open another terminal on the remote system, and log in as the root user on the remote system, so you can run scripts as root when prompted.
This section describes the following operating system tasks you must complete before you install Oracle Database:
Run the following commands to check your current system information:
To determine the physical RAM size, enter the following command:
# /usr/contrib/bin/machinfo | grep -i Memory
To determine the size of the configured swap space, enter the following command:
# /usr/sbin/swapinfo -a
If necessary, see your operating system documentation for information about how to configure additional swap space.
Note:
Oracle recommends that you take multiple values for the available RAM and swap space before finalizing a value. This is because the available RAM and swap space keep changing depending on the user interactions with the computer.
Contact your operating system vendor for swap space allocation guidance for your server. The vendor guidelines supersede the swap space requirements listed in this guide.
To determine the amount of disk space available in the /tmp directory, enter the following command:
# bdf /tmp
If the free space available in the /tmp directory is less than what is required, then complete one of the following steps:
Delete unnecessary files from the /tmp directory to meet the disk space requirement.
Set the TMP and TMPDIR environment variables when setting the oracle user's environment.
See Also:
"Configuring Oracle Software Owner Environment" for more information about settingTMP and TMPDIRExtend the file system that contains the /tmp directory.
To determine the amount of free disk space on the system, enter the following command:
# bdf
To determine if the system architecture can run the software, enter the following command:
# uname -m
Verify that the processor architecture matches the Oracle software release to install. For example, you should see the following for a x86-64 bit system:
ia64 (itanium)
If you do not see the expected output, then you cannot install the software on this system.
To view the shared memory kernel parameters (shmmni, shmseg, and shmmax) and determine if any changes are necessary for your system., run the following command:
# kctune -v shmmni # kctune -v shmseg # kctune -v shmmax
Use the kctune shmmni=1024 command to set the memory kernel parameter to the required value.
Ensure the following general minimum requirements on your system:
Ensure that the system is started with run level 3.
Ensure display cards provide at least 1024 x 768 display resolution, so that Oracle Universal Installer displays correctly while performing a system console-based installation.
Ensure that your system meets the following storage requirements:
Ensure that your system meets the disk space requirement for software files and date files as described in Table 3-1
At least 1 GB of space in the /tmp directory.
If the free space available in the /tmp directory is less than what is required, then complete one of the following steps:
Delete unnecessary files from the /tmp directory to meet the disk space requirement.
Set the TMP and TMPDIR environment variables when setting the oracle user's environment.
See Also:
"Configuring Oracle Software Owner Environment" for more information about settingTMP and TMPDIRExtend the file system that contains the /tmp directory.
Ensure that your system meets the following memory requirements:
Minimum: 1 GB of RAM
Recommended: 2 GB of RAM or more
Table 3-2 describes the relationship between the installed RAM and the configured swap space recommendation:
Secure operating systems are an important basis for general system security. Ensure that your operating system deployment is in compliance with common security practices as described in your operating system vendor security guide.
Oracle Universal Installer detects when the minimum requirements for an installation are not met, and creates shell scripts, called fixup scripts, to finish incomplete system configuration steps. If Oracle Universal Installer detects an incomplete task, then it generates fixup scripts (runfixup.sh). You can run the fixup script and click Fix and Check Again. The fixup script modifies both persistent parameter settings and parameters in memory, so you do not have to restart the system.
See Also:
"Cluster Verification Utility Reference" in Oracle Clusterware Administration and Deployment Guide for information about using thecluvfy commandThe Fixup script does the following tasks:
If necessary sets kernel parameters to values required for successful installation, including:
Shared memory parameters.
Open file descriptor and UDP send/receive parameters.
Creates and sets permissions on the Oracle Inventory (central inventory) directory.
Creates or reconfigures primary and secondary group memberships for the installation owner, if necessary, for the Oracle Inventory directory and the operating system privileges groups.
Sets shell limits if necessary to required values.
Oracle recommends that you do not modify the contents of the generated fixup script.
Note:
Using fixup scripts does not ensure that all the prerequisites for installing Oracle Database are met. You must still verify that all the preinstallation requirements are met to ensure a successful installation.Depending on the products that you intend to install, verify that you have the required operating system kernel and packages installed.
Requirements listed in this document are current as of the date listed on the title page. To obtain the most current information about kernel requirements, see the online version on the Oracle Technology Network at the following URL:
http://www.oracle.com/technetwork/indexes/documentation/index.html
Oracle Universal Installer performs checks your system to verify that it meets the listed operating system package requirements. To ensure that these checks complete successfully, verify the requirements before you start OUI.
Note:
Oracle does not support running different operating system versions on cluster members, unless an operating system is being upgraded. You cannot run different operating system version binaries on members of the same cluster, even if each operating system is supported.The compiler and patches listed in this section are supported on HP-UX Itanium systems for Oracle Database and Oracle Grid Infrastructure 12c:

To determine the distribution and version of HP-UX installed, enter the following command:
# uname -a
The output of this command is similar to the following:
HP-UX hostname B.11.31 U ia64 4156074294 unlimited-user license
In this example, the version of HP-UX is 11.31 and the processor is Itanium.
To determine the compiler installed, enter the following command:
# /usr/sbin/swlist -l product | grep -i compiler
To determine if a patch is installed, enter a command similar to the following:
# /usr/sbin/swlist -l patch | grep PHSS_37959
Alternatively, to list all installed patches, enter the following command:
# /usr/sbin/swlist -l patch | more
If a required patch is not installed, then download it from the HP Support Center website and install it:
If the website has a recent version of the patch, then download and install that version.
To verify if the system meets the minimum patch bundle requirements, use the following command:
# /usr/sbin/swlist -l bundle |grep QPK
The QPK (Quality Pack) bundles have version numbers of the form B.11.31.0809.326a (for the September 2008 release), B.11.31.0903.334a (for the March 2009 release), and so on.
If a required bundle, product, or fileset is not installed, then you must install it. See your operating system or software documentation for information about installing products.
Note:
There may be more recent versions of the patches listed in the preceding paragraph that are installed on the system. If a listed patch is not installed, then determine if a more recent version is installed before installing the version listed.If you require a CSD for WebSphere MQ, then refer to the following website for download and installation information:
Typically, the computer on which you want to install Oracle Database is connected to a network. Ensure that the computer host name is resolvable through a Domain Name System (DNS), a network information service (NIS), or a centrally-maintained TCP/IP host file, such as /etc/hosts. Use the ping command to ensure that your computer host name is resolvable. For example:
ping myhostname pinging myhostname.example.com [192.0.2.2] with 32 bytes of data: Reply from 192.0.2.2: bytes=32 time=138ms TTL=56
If your computer host name does not resolve, then contact your system administrator.
You must identify or create the following directories for the Oracle software:
Note:
Ensure that the paths you select for Oracle software, such as the Oracle home path and the Oracle base path, use only ASCII characters. Because installation owner names are used by default for some paths, this ASCII character restriction applies to user names, file names, and directory names.
Ensure that all paths used by the database software, such as the Oracle home path and the Oracle base path, use characters only from the following set: "# % & ' () * + , - . / : ; < = > ? @ _ A-Z a-z 0-9. This includes user names, file names, and directory names. At the time of this release, the use of other characters for an Oracle Grid Infrastructure home or Oracle Database home is not supported. The set of characters provided is further restricted by user and file naming rules of the operating system.
The Oracle base directory is a top-level directory for Oracle software installations. The Optimal Flexible Architecture (OFA) guidelines recommend that you use a path similar to the following for the Oracle base directory:
/mount_point/app/software_owner
mount_point is the mount point directory for the file system that contains the Oracle software.
The examples in this guide use /u01 for the mount point directory.
software_owner is the operating system user name of the software owner installing the Oracle software, for example oracle or grid.
Note:
If you start a database instance using the server parameter file (spfile) with the ORACLE_BASE environment variable set, then its value is automatically stored in spfile. If you unset the ORACLE_BASE environment variable and start the instance again, then the database uses the value of the Oracle base directory stored in spfile.You must specify the Oracle base directory that contains all Oracle products.
Note:
If you have an existing Oracle base directory, then you can select it from the Oracle Base list during the database installation. If you do not have an Oracle base, then you can create one by editing the text in the list box. By default, the list contains the existing value for the Oracle base. See "Installing the Oracle Database Software" for more information.You can use the same Oracle base directory for multiple installations or you can create separate Oracle base directories for different installations. If different operating system users install Oracle software on the same system, then each user must create a separate Oracle base directory. The following are examples of Oracle base directories that can exist on the same system:
/u01/app/oracle /u01/app/orauser
The Oracle Inventory directory (oraInventory) stores an inventory of all software installed on the system. It is required and shared by all Oracle software installations on a single system. If you have an existing Oracle Inventory path, then Oracle Universal Installer continues to use that Oracle Inventory.
The first time you install Oracle software on a system, Oracle Universal Installer provides an Optimal Flexible Architecture-compliant path in the format /u[01-09]/app, such as /u01/app. The user running the installation has permissions to write to that path. If this is true, then Oracle Universal Installer creates the Oracle Inventory directory in the path /u[01-09]/app/oraInventory. For example:
/u01/app/oraInventory
If you have set ORACLE_BASE for the oracle user during installation, then Oracle Universal Installer creates the Oracle Inventory directory one level above the ORACLE_BASE in the path ORACLE_BASE/../oraInventory. For example, if ORACLE_BASE is set to /u01/app/oracle, then the Oracle Inventory directory is created in the path /u01/app/oraInventory.
If you have neither created an OFA-compliant path nor set ORACLE_BASE, then the Oracle Inventory directory is placed in the home directory of the user that is performing the installation. For example:
/home/oracle/oraInventory
Oracle Universal Installer creates the directory that you specify and sets the correct owner, group, and permissions for it. You do not have to create it.
Note:
All Oracle software installations rely on the Oracle Inventory directory. Ensure that you back it up regularly.
Do not delete this directory unless you have completely removed all Oracle software from the system.
By default, the Oracle Inventory directory is not installed under the Oracle Base directory. This is because all Oracle software installations share a common Oracle Inventory, so there is only one Oracle Inventory for all users. Whereas, there is a separate Oracle Base for each user.
The Oracle home directory is the directory where you install the software for a particular Oracle product. You must install different Oracle products or different releases of the same Oracle product in separate Oracle home directories. When you run Oracle Universal Installer, it prompts you to specify the path to this directory and a name that identifies it. In accordance with the OFA guidelines, Oracle strongly recommends that the Oracle home directory you specify is a subdirectory of the Oracle base directory for the user account performing the installation. Oracle recommends that you specify a path similar to the following for the Oracle home directory:
oracle_base/product/11.2.0/db_home_1 oracle_base/product/12.1.0/dbhome_1 oracle_base/product/12.1.0/grid
Oracle Universal Installer creates the directory path that you specify under the Oracle base directory. It also sets the correct owner, group, and permissions on it. You do not have to create this directory.
Note:
During the installation, you must not specify an existing directory that has predefined permissions applied to it as the Oracle home directory. If you do, then you may experience installation failure due to file and group ownership permission errors.Before starting the installation, you must either identify an existing Oracle base directory or, if required, create one. This section contains information about the following topics:
Note:
You can create an Oracle base directory, even if other Oracle base directories exist on the system.Existing Oracle base directories may not have paths that follow the Optimal Flexible Architecture (OFA) guidelines. However, if you identify an existing Oracle Inventory directory or existing Oracle home directories, then you can usually identify the Oracle base directories, as follows:
Identifying an existing Oracle Inventory directory. See "Creating the Oracle Inventory Group If an Oracle Inventory Does Not Exist" for more information.
Note:
Oracle recommends that you do not put theoraInventory directory under the Oracle base directory for a new installation. If you have an existing installation, then follow the steps in this section.Identifying an existing Oracle home directory
Enter the following command to display the contents of the oratab file:
# more /var/opt/oracle/oratab
If the oratab file exists, then it contains configuration information similar to the following:
*:/u03/app/oracle/product/12.1.0/dbhome_1:N *:/opt/orauser/infra_904:N *:/oracle/9.2.0:N
The directory paths specified on each line identify Oracle home directories. Directory paths that end with the user name of the Oracle software owner to use are valid choices for an Oracle base directory. If you intend to use the oracle user to install the software, then you can choose one of the following directories listed in the previous example:
/u03/app/oracle /oracle
Note:
If possible, choose a directory path similar to the first one (/u03/app/oracle). This path complies with the OFA guidelines.Identifying an existing Oracle base directory
After you locate the Oracle home directory, run a similar command to confirm the location of Oracle base:
cat /u01/app/oraInventory/ContentsXML/inventory.xml
Before deciding to use an existing Oracle base directory for this installation, ensure that it meets the following conditions:
It is not on the same file system as the operating system.
To determine the free disk space on the file system where the Oracle base directory is located, enter the following command:
# bdf oracle_base_path
See the following sections for more information:
If an Oracle base directory exists and you want to use it, then see "Choosing a Storage Option for Oracle Database and Recovery Files" section.
When you configure the oracle user's environment later in this chapter, set the ORACLE_BASE environment variable to specify the directory you chose.
If an Oracle base directory does not exist on the system or to create an Oracle base directory, see "Creating an Oracle Base Directory".
Before you create an Oracle base directory, you must identify an appropriate file system with sufficient free disk space.
To identify an appropriate file system, perform the following:
Determine the free disk space on each mounted file system, using the following command:
# bdf
Identify a file system that has the appropriate amount of free space, from the display:
The file system that you identify can be a local file system, a cluster file system, or an NFS file system on a certified NAS device.
Note the name of the mount point directory for the file system that you identified.
To create the Oracle base directory and specify the correct owner, group, and permissions for it, perform the following:
Enter commands similar to the following to create the recommended subdirectories in the mount point directory that you identified and set the appropriate owner, group, and permissions on them:
# mkdir -p /mount_point/app/oracle_sw_owner # chown -R oracle:oinstall /mount_point/app/oracle_sw_owner # chmod -R 775 /mount_point/app/oracle_sw_owner
For example:
# mkdir -p /u01/app/oracle # chown -R oracle:oinstall /u01/app/oracle # chmod -R 775 /u01/app/oracle
When you configure the oracle user's environment later in this chapter, set the ORACLE_BASE environment variable to specify the Oracle base directory that you created.
Oracle Database files include data files, control files, redo log files, the server parameter file, and the password file. For all installations, you must choose the storage option to use for Oracle Database files. During the database installation, you must choose the storage option to use for recovery files (the fast recovery area). You do not have to use the same storage option for each file type.
Note:
Database files and recovery files are supported on file systems and Oracle ASM.Use the following guidelines when choosing the storage options for each file type:
Choose any combination of the supported storage options for each file type.
Determine whether you want to use Oracle ASM for Oracle Database files, recovery files, or both. See "Identifying Storage Requirements for Oracle Automatic Storage Management" for more information.
See "Database Storage Options" for more information about these storage options
For information on how to configure disk storage before you start the installation, see one of the following sections depending on your choice:
To use a file system for database or recovery file storage, see the "Creating Directories for Oracle Database or Recovery Files" section.
To use Oracle ASM for database or recovery file storage, see the "Configuring Storage for Oracle Automatic Storage Management" section.
To identify existing disk groups and determine the free disk space that they contain, see the "Using an Existing Oracle Automatic Storage Management Disk Group" section.
This section contains the following topics:
If you choose to place the Oracle Database files on a file system, then use the following guidelines when deciding where to place them:
The default path suggested by Oracle Universal Installer for the database file directory is a subdirectory of the Oracle base directory.
You can choose either a single file system or more than one file system to store the database files:
If you want to use a single file system, then choose a file system on a physical device that is dedicated to the database.
For best performance and reliability, choose a RAID device or a logical volume on more than one physical device and implement the stripe-and-mirror-everything (SAME) methodology.
If you want to use more than one file system, then choose file systems on separate physical devices that are dedicated to the database.
This method enables you to distribute physical input-output operations and create separate control files on different devices for increased reliability. It also enables you to fully implement the OFA guidelines. You can choose the Advanced database creation option to implement this method.
If you intend to create a preconfigured database during the installation, then the file system (or file systems) that you choose must have at least 2 GB of free disk space.
For production databases, you must estimate the disk space requirement depending on the use of the database.
For optimum performance, the file systems that you choose must be on physical devices that are used only by the database.
The oracle user must have write permissions to create the files in the path that you specify.
Note:
You must perform this procedure only to place the Oracle Database or recovery files on a separate file system from the Oracle base directory.To create directories for the Oracle database or recovery files on separate file systems from the Oracle base directory:
Use the following command to determine the free disk space on each mounted file system:
# bdf
Identify the file systems to use, from the display:
| File Type | File System Requirements |
|---|---|
| Database files | Choose either:
|
| Recovery files | Choose a file system with at least 2.4 GB of free disk space |
If you are using the same file system for many file types, then add the disk space requirements for each type to determine the total disk space requirement.
Note the names of the mount point directories for the file systems that you identified.
Enter commands similar to the following to create the recommended subdirectories in each of the mount point directories and set the appropriate owner, group, and permissions on them:
Database file directory:
# mkdir /mount_point/oradata # chown oracle:oinstall /mount_point/oradata # chmod 775 /mount_point/oradata
The default location for the database file directory is $ORACLE_BASE/oradata.
Recovery file directory (fast recovery area):
# mkdir /mount_point/fast_recovery_area # chown oracle:oinstall /mount_point/fast_recovery_area # chmod 775 /mount_point/fast_recovery_area
The default fast recovery area is $ORACLE_BASE/fast_recovery_area. Oracle recommends that you keep the fast recovery area on a separate physical disk than that of the database file directory. This method enables you to use the fast recovery area to retrieve data if the disk containing oradata is unusable for any reason.
See "Configuring Servers for Oracle Grid Infrastructure for a Standalone Server" and "Stopping Existing Oracle Processes" for information about using Oracle ASM for storage.
