• Solaris and Installation-Specific Issues and Restrictions

Installation Overview

Installing Oracle8i involves the following steps:

1. Satisfy Prerequisites: Make sure the local system satisfies the hardware, software, memory, and disk space requirements for the products you want to install. These requirements and restrictions are described in this chapter.

2. Pre-Installation: Make sure the UNIX environment is properly set up and complete pre-installation tasks for the products you want to install. See Chapter 2, "Pre-Installation".

3. Install: Use the new Oracle Universal Installer provided on your software CD-ROM to install Oracle products. See Chapter 3, "Installation".

4. Post-Installation: Create database objects, establish the user environment, and configure the installed Oracle products for the local system. See Chapter 4, "Post-Installation".

5. Client Installations: If you want to install client tools, applications, and client interfaces not included with the Oracle8i Release 2 (8.1.6) CD-ROM, check the requirements and instructions in the documentation for those products.

Product Installation Categories and Installation Types

There are three categories of products included with Oracle8i Release 2 (8.1.6) for Sun SPARC Solaris.

• Oracle8i Enterprise Edition

• Oracle8i Management Infrastructure

• Oracle8i Client

Each category of products consists of multiple installation types. An overview of these product categories and types follows in Table 1-1, "Oracle8i Product Installation Categories and Types". For descriptions and version numbers of individual software products included on the Oracle8i Release 2 (8.1.6) for Sun SPARC Solaris CD-ROM, refer to Appendix A, "Oracle8i Products".

Table 1-1 Oracle8i Product Installation Categories and Types

System Installation Requirements

Verify that your system meets the requirements described in the following sections before you install Oracle8i Release 2 (8.1.6) products.

• Hardware Requirements

• Disk Space Requirements

• Operating System Software Requirements

• Online Documentation Requirements

• Additional Product-Specific Installation Requirements

Hardware Requirements

To install Oracle8i products included with this release, your Sun SPARC Solaris system must meet the minimum hardware requirements listed in Table 1-2.

Table 1-2 Hardware Requirements

To determine the amount of RAM memory installed on your system, enter the following command:

$ /usr/sbin/prtconf | grep size

To determine the bytes of swap space currently configured on your system, enter the following command and multiply the BLOCKS column by 512:

$ swap -l

Disk Space Requirements

The Oracle Universal Installer allows you to choose your installation category and type as described in "Product Installation Categories and Installation Types". Your choices will determine how much disk space you will need as shown in Table 1-3, Table 1-4, and Table 1-5. Disk space requirements do not account for the size of your database. A production Oracle database server supporting many users requires significantly greater disk space and memory.

To determine your current operating system information, enter the following command:

$ uname -a

To determine which operating system patches are installed, enter the following command:

$ showrev -p

To determine which operating system packages are installed, enter the following command:

$ pkginfo -i [package_name]

If you enter pkginfo -i, all installed packages are listed.

To determine if your X-windows system is working properly on your local system, enter the following command:

$ xclock

If a clock is not displayed on your screen, X-windows is not configured correctly. See "DISPLAY" for instructions on configuring X-windows.

To determine if you are using the correct system executables, enter the following commands:

$ /usr/bin/which make
$ /usr/bin/which ar
$ /usr/bin/which ld
$ /usr/bin/which nm

Each of the four commands above should point to the /usr/ccs/bin directory. If not, add /usr/ccs/bin to the beginning of the PATH environment variable in the current shell. See "PATH" for instructions on setting the PATH variable.

Online Documentation Requirements

To view online documentation included with the Oracle8i CD-ROM, use a web browser such as Netscape Navigator 4.0 or higher running on a UNIX system.

The software requirements in Table 1-11 apply to a default installation of Legato Storage Manager, with no relocation of the software components.

Table 1-11 Legato Storage Manager Software Requirements

Solaris and Installation-Specific Issues and Restrictions

The following issues and restrictions can affect the installation or use of Oracle8i on Sun SPARC Solaris. Check the Release Notes that accompany this release and the README files in the $ORACLE_HOME/relnotes directory before using Oracle8i. For Release 2 (8.1.6), the README files are uncompressed and linked to the top-level HTML file in the doc directory. README files for other products on the Oracle8i CD-ROM are in the doc or admin/doc directories for the respective products.

New ORACLE_HOME

Do not install Oracle8i Release 2 (8.1.6) into an ORACLE_HOME directory containing any Oracle Software earlier than 8.1.5. If you install Oracle8i Release 2 (8.1.6) into an 8.1.5 ORACLE_HOME, Oracle Universal Installer removes most existing 8.1.5 products before the 8.1.6 products are installed. Do not remove 8.1.5 products that remain after the upgrade to 8.1.6.

Oracle Corporation recommends that you install Oracle8i Release 2 (8.1.6) products into a new ORACLE_HOME.

Java Runtime Environment (JRE)

The JRE shipped with Oracle8i is used by Oracle Java applications such as the Oracle Universal Installer and is the only one supported to run with these applications. Customers should not modify this JRE, unless it is done through a patch provided by Oracle Support Services.

The inventory can contain multiple versions of the JRE, each of which can be used by one or more products or releases. The Installer creates the oraInventory directory the first time it is run to keep an inventory of products that it installs on your system as well as other installation information. The location of oraInventory is defined in /var/opt/oracle/oraInst.loc.

Products in an ORACLE_HOME access the JRE through a symbolic link in $ORACLE_HOME/JRE to the actual location of a JRE within the inventory. Customers should not modify the symbolic link unless it is done through a patch provided by Oracle Support Services.

The Solaris patches Table 1-12 and Table 1-13are required or recommended for JRE 1.1.8_10 and can be obtained from:

http://sunsolve.sun.com

Table 1-12 Solaris 2.6 Patches for JRE 1.1.8_10

Table 1-13 Solaris 7 Patches for JRE 1.1.8_10

To determine which operating system patches are installed, enter the following command:

$ showrev -p

Character Mode

Installation can no longer be performed using character mode. However, you can configure the Oracle Universal Installer to perform a non-interactive installation of Oracle products. The Installer can be run in non-interactive mode directly from your system's X-windows console or via an X-terminal or PC X-terminal on a remote system. For more information on the non-interactive installation of Oracle products, see "Non-Interactive Installation and Configuration".

Upgrading and Migrating

If you are upgrading an existing system, there are issues which exceed the scope of this manual. See Oracle8i Migration for details on upgrade and migration procedures. If you are upgrading an Oracle Enterprise Manager repository, see the Oracle Enterprise Manager Configuration Guide.

It is possible to migrate an Oracle7 database, release 7.1.4 or higher, or upgrade an Oracle8 database, release 8.0.3 or higher, to Oracle8i Release 2 (8.1.6). To migrate from an Oracle7 database lower than 7.1.4, you must first upgrade to an Oracle7 database, release 7.1.4 or higher, and then use the Oracle Data Migration Assistant to migrate to Oracle8i.

File Systems

Oracle8i Server must be able to verify that file writes have been made to disk. File systems that do not support this verification are not supported for use with Oracle databases, although Oracle software can be installed on them.

Optimal Flexible Architecture

Optimal Flexible Architecture (OFA), Oracle's standard set of configuration guidelines for Oracle databases, is supported, but not enforced, by the Oracle Universal Installer. The starter database included with the Typical installation type of Oracle8i Enterprise Edition is created under a single mount point. See "Identifying Your Database Environment" for more information about the databases you can create during installation.

For more information about OFA, see Appendix A, "Optimal Flexible Architecture", in the Oracle8i Administrator's Reference.

Solaris 2.3, 2.4, and 2.5

Solaris 2.3, 2.4, and 2.5 are not supported for use with Oracle8i Release 2 (8.1.6). You must be using Solaris 2.6 or Solaris 7. See Table 1-6 for details of operating system and patch level requirements.

Very Large Files

Oracle8i Release 2 (8.1.6) includes native support for files greater than 2 GB. Check your shell to determine whether it will impose a limit.

To check current soft shell limits, enter the following command:

$ ulimit -Sa

To check maximum hard limits, enter the following command:

$ ulimit -Ha

The file (blocks) value should be multiplied by 512 to obtain the maximum file size imposed by the shell. A value of unlimited is the operating system default and is the maximum value of 1 TB. See Table 1-14, "Oracle File Size Limits" for Oracle-specific file size limits. The db_block_size parameter is defined in the $ORACLE_HOME/dbs/initsid.ora file.

Table 1-14 Oracle File Size Limits

Oracle Parallel Server Restriction

Because all Oracle databases on a cluster linked in Parallel Server mode must match the word size of the Cluster Group Services executable, they must all run only a 32-bit executable. Mixing word sizes of parallel server executables, even across different databases, will not work in 8.1.x. This restriction does not apply to Oracle executables that are not linked in Parallel Server modes.
