12 Installing Oracle Database Gateway for DRDA

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:

  1. Ensure that the system meets all of the hardware and software requirements specified in "System Requirements for Oracle Database Gateway for DRDA".

  2. 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.

* 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 concurrent TCP/IP connections open by each user

  • Number of data items being transferred between the gateway and the remote transaction program

  • Additional factors such as configured network buffer size

Checking the Hardware Requirements

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

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

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

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

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

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

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

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

    Operating System Command
    IBM AIX on POWER Systems (64-Bit) # df -k /tmp
    Linux x86 64 bit # df -k /tmp
    Oracle Solaris on SPARC (64-Bit) # df -k /tmp
    Oracle Solaris on x86-64 (64-Bit) # df -k /tmp
    HP-UX Itanium # bdf /tmp

  4. To determine the amount of disk space available on the system enter the following commands:

    Operating System Command
    IBM AIX on POWER Systems (64-Bit) # df -k
    Linux x86 64 bit # df -k
    Oracle Solaris on SPARC (64-Bit) # df -k
    Oracle Solaris on x86-64 (64-Bit) # df -k
    HP-UX Itanium # bdf
