10 Installing Oracle Database Gateway for ODBC

This chapter provides information about the hardware and software requirements and the installation procedure for Oracle Database Gateway for ODBC.

To install the gateway, follow these steps:

Ensure that the system meets all of the hardware and software requirements specified in "System Requirements for Oracle Database Gateway for ODBC"
Run the Oracle Universal Installer.

See "Step Through the Oracle Universal Installer" for more information about running the Oracle Universal Installer

Oracle Universal Installer is a menu-driven utility that guides you through the installation of the gateway by prompting you with action items. The action items and the sequence in which they appear depend on your platform.

See Table 10-3 for a description of the installation procedure of Oracle Database Gateway for ODBC

10.1 System Requirements for Oracle Database Gateway for ODBC

This section provides information about the hardware and software requirements for the gateway. It contains the following sections:

"Hardware Requirements" on page 10-1
"Software Requirements" on page 10-3

10.1.1 Hardware Requirements

Table 10-1 lists the minimum hardware requirements for Oracle Database Gateway for ODBC.

Table 10-1 Hardware requirements for Oracle Database Gateway for ODBC

Hardware Items	Required for AIX-Based System	Required for HP-UX Itanium	Required for Solaris Operating System (SPARC)	Required for Linux x86	Required for Linux x86 64 bit**
Temporary Disk Space	400 MB	400 MB	400 MB	400 MB	400 MB
Disk Space	1.5 GB	1.5 GB	750 MB	750 MB	750 MB
Physical Memory*	512 MB	512 MB	512 MB	512 MB	512 MB
Swap Space	1 GB	1 GB	1 GB	1 GB	1 GB
Processor	IBM RS/6000 AIX-Based System Processor	HP Itanium processor for hp-ux 11	Sun Solaris Operating System (SPARC) Processor	x86	x86_64

* The minimum swap space is 1 GB (or twice the size of RAM). On systems with 2 GB or more of RAM, the swap space can be between one and two times the size of RAM. On AIX systems with 1 GB or more of memory, do not increase the swap space more than 2 GB.

** Database Gateway for ODBC on Linux x86-64 is now a 64-bit application that requires the use of a 64-bit third party ODBC Driver

10.1.1.1 Checking the Hardware Requirements

To ensure that the system meets the minimum requirements, follow these steps:

To determine the physical RAM size, enter one of the following commands:

Operating System	Command
AIX	# `/usr/sbin/lsattr -E -l sys0 -a realmem`
HP-UX Itanium	`# /usr/contrib/bin/machinfo \| grep -i Memory`
Solaris (SPARC)	# `/usr/sbin/prtconf \| grep "Memory size"`
Linux x86	`# grep MemTotal /proc/meminfo`
Linux x86 64 bit	`# grep MemTotal /proc/meminfo`

If the size of the physical RAM installed in the system is less than the required size, you must install more memory before continuing.

To determine the size of the configured swap space, enter one of the following commands:

Operating System	Command
AIX	`# /usr/sbin/lsps -a`
HP-UX Itanium	`# /usr/sbin/swapinfo -a`
Solaris (SPARC)	`# /usr/sbin/swap -s`
Linux x86	`# grep SwapTotal /proc/meminfo`
Linux x86 64 bit	`# grep SwapTotal /proc/meminfo`

If necessary, see your operating system documentation for information about how to configure additional swap space.

To determine the amount of disk space available in the /tmp directory enter the following commands:

Operating System Command

AIX # df -k /tmp

HP-UX Itanium # bdf /tmp

Solaris (SPARC) # df -k /tmp

Linux x86 # df -k /tmp

Linux x86 64 bit # df -k /tmp
To determine the amount of disk space available on the system enter the following commands:

Operating System Command

AIX # df -k

HP-UX Itanium # bdf

Solaris (SPARC) # df -k

Linux x86 # df -k

Linux x86 64 bit # df -k

Operating System	Command
AIX	`# df -k /tmp`
HP-UX Itanium	`# bdf /tmp`
Solaris (SPARC)	`# df -k /tmp`
Linux x86	`# df -k /tmp`
Linux x86 64 bit	`# df -k /tmp`

Operating System	Command
AIX	`# df -k`
HP-UX Itanium	`# bdf`
Solaris (SPARC)	`# df -k`
Linux x86	`# df -k`
Linux x86 64 bit	`# df -k`

10.1.2 Software Requirements

The following section describes the minimum software requirements for Oracle Database Gateway for ODBC.

```
# oslevel -r
```
To determine which version of HP-UX Itanium is installed, enter the following command:
```
# uname -a
```
