1 Oracle Database Installation Checklist

Confirm Server Make and Architecture:

Confirm that server make, model, core architecture, and host bus adaptors (HBA) are supported to run with Oracle Database and Oracle Grid Infrastructure for a standalone server.

Check Runlevel, Display and Network Setup:

• Server should be started in runlevel 3.

• Server display cards provide at least 1024 x 768 display resolution.

• Server is connected to the network, contains a display monitor and DVD drive.

Allocate Local Disk Space for Oracle Software:

• Based on the Oracle Database edition you intend to install, server meets the disk space requirements listed in "Server Storage Minimum Requirements."

• At least 6.9 GB of disk space for an Oracle Grid Infrastructure for a standalone server installation.

Random Access Memory (RAM):

• At least 1 GB RAM for Oracle Database installations. See Table 3-3.

• At least 4 GB of RAM for Oracle Grid Infrastructure for a standalone server including installations where you plan to install Oracle Database. See Table 5-1.

Temporary Disk Space Allocation:

At least 1 GB allocated to /tmp.

Check Storage Hardware:

Either Storage Area Network (SAN) or Network-Attached Storage (NAS). See Appendix C, "Using NAS Devices".

Operating System:

• Supported in the list of supported distribution, releases, kernels, and packages listed in "Operating System Requirements for Oracle Solaris on SPARC (64-Bit)" and "Operating System Requirements for Oracle Solaris on x86-64 (64-Bit)."

• OpenSSH installed manually, if you do not have it installed already as part of a default installation.

Kernel Parameters and Shell Limits:

Check "Configuring Kernel Parameters on Oracle Solaris" and "Configuring Shell Limits for Oracle Solaris" to review the minimum kernel parameter requirements for installation. If your parameter settings do not meet the minimum requirements for installation, then Oracle Universal Installer (OUI) generates a fixup script that can change these settings to the minimum required levels for installation.

Create Groups and Users.

Review "Creating Required Operating System Groups and Users" for information about the groups and users you need to create for the kind of deployment you want to do.

Group and user names must use only ASCII characters.

Review Oracle Inventory (oraInventory) and OINSTALL Group Requirements.

The Oracle Inventory directory is the central inventory of Oracle software installed on your system. Users who have the Oracle Inventory group as their primary group are granted the OINSTALL privilege to read and write to the central inventory.

• If you have an existing installation, then OUI detects the existing oraInventory directory from the /etc/oraInst.loc file, and uses this location.

• If you are installing Oracle software for the first time, and your system does not have an oraInventory directory, then the installer creates an Oracle inventory that is one directory level up from the Oracle base for the Oracle Grid Infrastructure install, and designates the installation owner's primary group as the Oracle Inventory group. Ensure that this group is available as a primary group for all planned Oracle software installation owners.

Unset Oracle Software Environment Variables.

If you have had an existing installation on your system, and you are using the same user account to install this installation, then unset the ORACLE_HOME, ORACLE_BASE, ORACLE_SID, TNS_ADMIN environment variables and any other environment variable set for the Oracle installation user that is connected with Oracle software homes.

Configure the Oracle Software Owner Environment

Configure the environment of the oracle or grid user by performing the following tasks:

• Set the default file mode creation mask (umask) to 022 in the shell startup file.

• Set the DISPLAY environment variable.

See, "Configuring Oracle Software Owner Environment".

Create Mount Point Paths for the Software Binaries.

Oracle recommends that you follow the guidelines for an Optimal Flexible Architecture configuration, as described in Appendix F, "Optimal Flexible Architecture".

Oracle Users and Home Paths Must Use ASCII Characters Only

Ensure Oracle home paths and other Oracle directory names use ASCII characters only. Also ensure Oracle installation owner user names are ASCII characters only, because installation owner names are used for some default Oracle softwarse paths.

Enable Remote Display Configuration

If you are installing the software from an X Window System workstation or X terminal, then log in as root and enable remote display. See, "Logging In to the System as root".

Decide the Database Storage Option

During the database installation, you must specify one of the following storage options for database files:

• File System

  Oracle Database Configuration Assistant (Oracle DBCA) creates the database files in a directory on a file system mounted on the computer. Oracle recommends that the file system be separate from the file systems used by the operating system or the Oracle software. The file system can be any of the following:

  - A file system on a disk that is physically attached to the system

  - A file system on a logical volume manager (LVM) volume or a RAID device

  - A network file system (NFS) mounted from a certified network-attached storage (NAS) device.

• Oracle Automatic Storage Management

  Oracle Automatic Storage Management (Oracle ASM) is installed as part of an Oracle Grid Infrastructure installation. If you plan to use Oracle ASM, then you must install Oracle Grid Infrastructure before you install and create the database.

See "Database Storage Options".

Decide If You Want to Enable Recovery

If you decide to enable recovery during the database installation, then select one of the following options:

• File System: Oracle Universal Installer (OUI) provides you with an option to configure the fast recovery area location.

• Oracle Automatic Storage Management: This option allows you only to use the same disk group for both Oracle Database files and recovery files..

See "Identifying Storage Requirements for Oracle Automatic Storage Management" and "Creating a Fast Recovery Area Disk Group".

Verify if Oracle Grid Infrastructure Exists

If you want to use Oracle ASM or Oracle Restart, then you must 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.

Check Running Oracle Processes, and Shut Down if Necessary:

• On a standalone database not using Oracle ASM: You do not need to shut down the database while you install Oracle Grid Infrastructure.

• On a standalone database using Oracle ASM: Stop the existing Oracle ASM instances. The Oracle ASM instances are restarted during installation.

See "Stopping Existing Oracle Processes".

Ensure cron Jobs Do Not Run During Installation

If the installer is running when daily cron jobs start, then you may encounter unexplained installation problems if your cron job is performing cleanup, and temporary files are deleted before the installation is finished. Oracle recommends that you complete installation before daily cron jobs are run, or disable daily cron jobs that perform cleanup until after the installation is completed.

Decide if You Want to Install Other Languages

During installation, you are asked if you want translation of user interface text into languages other than the default, which is English. If the language set for the operating system is not supported by the installer, then by default the installer runs in the English language.

See Oracle Database Globalization Support Guide for detailed information about character sets and language configuration.

Decide Your Management Option

By default, Oracle Database 12c is managed by Oracle Enterprise Manager Database Express.

However, if you have an existing Oracle Management Agent, and decide to use Oracle Enterprise Manager Cloud Control to centrally manage your database, then obtain the following information to enter during the database installation:

• OMS host

• OMS port

• EM admin username

• EM admin password

See Also:

• Oracle Database 2 Day DBA for configuring Oracle Enterprise Manager Database Express

• Oracle Enterprise Manager Cloud Control Administrator's Guide for information about how to use Oracle Enterprise Manager Cloud Control to discover targets

Determine Root Script Execution Plan.

See, "Determining Root Script Execution Plan" to determine how you plan to run root scripts during an Oracle Grid Infrastructure installation.

Consider Memory Allocation and Automatic Memory Management

You can enable automatic memory management either during, or after the database installation. Enabling automatic memory management after installation involves a shutdown and restart of the database.

With automatic memory management, the Oracle Database instances automatically manage and tune memory for you. With automatic memory management, you choose a memory target, and the instance automatically distributes memory between the system global area (SGA) and the instance program global area (instance PGA). As memory requirements change, the instance dynamically redistributes memory between the SGA and instance PGA.
