This chapter provides information about the hardware and software requirements and the installation procedure for Oracle Database Gateway for Informix.
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 Informix".
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 4-3 for a description of the installation procedure of Oracle Database Gateway for Informix.
This section provides information about the hardware and software requirements for the gateway. It contains the following sections:
Table 4-1 lists the minimum hardware requirements for Oracle Database Gateway for Informix.

* 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.
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 |
The following section describes the minimum software requirements for Oracle Database Gateway for Informix.
Table 4-2 lists the minimum operating system version required for Oracle Database Gateway for Informix. If your operating system is lower than the minimum requirements, upgrade your operating system to meet the specified levels.

To ensure that the system meets the minimum requirements, follow these steps:
To determine which version of AIX is installed, enter the following command:
# oslevel -r
To determine which version of HP-UX Itanium is installed, enter the following command:
# uname -a
To determine which version of Solaris Operating System (SPARC) is installed, enter the following command:
# uname -r
To determine which distribution and version of Linux x86 is installed, enter the following command:
# cat /etc/issue
To determine which distribution and version of Linux x86 64 bit is installed, enter the following command:
# cat /proc/version
