This chapter provides information about the hardware and software requirements and the installation procedure of Oracle Database Gateway for DRDA.
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 DRDA".
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 12-3 for a description of the installation procedure of Oracle Database Gateway for DRDA.
This section provides information about the hardware and software requirements for the gateway. It contains the following sections:
Table 12-1 lists the minimum hardware requirements for Oracle Database Gateway for DRDA.

* 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.
For most installations, a minimum of 256 MB of real memory is recommended for the first user to support the Oracle Database Gateway for DRDA.
The total real memory requirement for each concurrent use of the gateway depends on the following factors:
Number of data items being transferred between the gateway and the remote transaction program
Additional factors such as configured network buffer size
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 64 bit | # /usr/sbin/dmesg | grep "Physical:" |
| Solaris (SPARC) | # /usr/sbin/prtconf | grep "Memory size" |
| Linux x86 | # grep MemTotal /proc/meminfo |
| Linux x86 64 bit | # grep MemTotal /proc/meminfo |
| Linux Itanium 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 64 bit | # /usr/sbin/swapinfo -a |
| Solaris (SPARC) | # /usr/sbin/swap -s |
| Linux x86 | # grep SwapTotal /proc/meminfo |
| Linux x86 64 bit | # grep SwapTotal /proc/meminfo |
| Linux Itanium 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 64 bit | # df -k /tmp |
| Solaris (SPARC) | # df -k /tmp |
| Linux x86 | # df -k /tmp |
| Linux x86 64 bit | # df -k /tmp |
| Linux Itanium 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 64 bit | # df -k |
| Solaris (SPARC) | # df -k |
| Linux x86 | # df -k |
| Linux x86 64 bit | # df -k |
| Linux Itanium 64 bit | # df -k |
The following section describes the minimum software requirements for Oracle Database Gateway for DRDA.
Table 12-2 lists the minimum operating system version required for Oracle Database Gateway for DRDA. If your operating system is lower than the minimum requirements, upgrade your operating system to meet the specified levels.

# oslevel -r
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
