Oracle Universal Installer (OUI)

The Oracle Tuxedo Mainframe Adapter for TCP 12c Release 2 (12.2.2) product software installer is based on the Oracle Universal Installer (OUI). To install the Oracle Tuxedo Mainframe Adapter for TCP 12c Release 2 (12.2.2) product software on your host, you must know how to use OUI to install Oracle products. For more information, see Introduction to Oracle Universal Installer.

Modes of Installation

You can use OUI to install Oracle products in any of the three following modes:

•	Interactive:

Use OUI interactive mode to use the graphical user interface to walk through the installation, providing information in the installation dialogs when prompted. This method is most useful when installing a small number of products in different setups on a small number of hosts.

•

Silent:

Use OUI silent installation mode to bypass the graphical user interface and supply the necessary information in a response file. This method is most useful when installing the same product multiple times on multiple hosts. By using a response file, you can automate the installation of a product for which you know the installation parameters.

Installation Media

Note:

When you invoke runInstaller.sh (UNIX), you should invoke it from the directory where this command is present, or you must specify the complete path to runInstaller.sh (UNIX).

Special Instructions for UNIX Users

The following sections describe special instructions that apply when you are installing certain products on a UNIX system.

Failed to Connect to Server Error

If you receive an Xlib error or a "Failed to connect to Server" error when you are running OUI on the Solaris operating system, do the following:

1.	Define the following environment variable on the host computer where you are running OUI:

%setenv DISPLAY <machine name>:0.0

2.	Replace <machine name> with the name of the computer that will display OUI.

3.	On the computer that will display OUI, enter the following command, which allows other computers to display information on the computer monitor: %xhost +

4.	Rerun the runInstaller.sh script after you have set the DISPLAY environment variable.

Note:

You can run OUI without specifying the DISPLAY variable by running in silent mode using a response file.

Providing a UNIX Installer Location with Root Privileges

You must have root privileges to perform various UNIX installation operations. For example, you must have root privileges to be able to create the OUI inventory.

If you are installing OUI for the first time, you are prompted to run a shell script from another terminal window before proceeding with the installation. OUI prompts you to run root.sh after installation completes only if the script is required to run as root before configuration assistants are run. Otherwise, you are prompted to run root.sh as root later.

Note:

When running OUI in silent mode, if root.sh is required prior to configuration assistants, OUI skips configuration assistants during the installation. You must run root.sh as root and then run the skipped configuration assistants after the silent installation is complete.

To successfully run the required shell script:

1.	Leave the OUI window open and open another terminal window.

2.	In the new terminal window, use the substitute user command to log in with root privileges: su -root

3.	Change directory to the Oracle home into which you are currently installing your Oracle software product.

4.	Run the shell script ./root.sh.

5.	When the script is finished and you are returned to the command prompt, exit from the new terminal window and return to OUI to continue installation.

Note:

Do not exit the installation to run the shell script. Exiting the installation removes this script.

You are prompted to run the script only the first time you install.

Providing a UNIX Group Name

If you are installing a product on a UNIX system, the Installer also prompts you to provide the name of the group that owns the base directory.

You must choose a UNIX group name that has permissions to update, install, and remove Oracle software. Members of this group must have write permissions for the chosen base directory.

Only users who belong to this group are able to install or remove software on this host.

About Oracle Universal Installer Log Files

When you install or deinstall products using OUI, important information about each installation is saved not only in the inventory, but also in a series of log files, located in the following directory:

$ORACLE_HOME/cfgtoollogs

You can use these log files to troubleshoot installation problems. These files are also crucial for removing and configuring the various software components you install on your UNIX computer. OUI displays the name and location of the current session log file on the Install page. Each installation or configuration utility provides a separate folder containing the logs inside the $ORACLE_HOME/cfgtoollogs folder.

Note:

The logs used to remove products are different from the installActions<timestamp>.log generated during the install process. The installActions<timestamp>.log is easier to read and can be used to view the operations performed at installation time.

Oracle Internationalization

Installation Dialogs Language

OUI runs in the operating system language. OUI uses the language that Java detects, the system locale value, and sets that to the default language. OUI dialogs are displayed in this language if available. If specific OUI dialogs are not translated in the language of the operating system, these dialogs are shown in English.

OUI displays the translated GUI only if the variable NLS_ENABLED has been set to TRUE in the oraparam.ini file. If the NLS_ENABLED variable is set to FALSE, all text is shown in English.

Note:

The dialogs displayed for internationalization can only be customized parts; some of them are embedded in OUI.

•	Oracle Tuxedo Mainframe Adapter for TCP

The component that contains the Oracle Tuxedo Mainframe Adapter for TCP software files.

Hardware and Software Prerequisites

The Oracle Tuxedo Mainframe Adapter for TCP must be installed into an Oracle Home which has already installed Oracle Tuxedo 12c Release 2 (12.2.2) server component, and Rolling Patch 003 or higher releases.

System Requirements

Oracle Tuxedo Mainframe Adapter for TCP 12c Release 2 (12.2.2) must be installed on a supported OS version for the given platform. Refer to “Oracle Tuxedo Mainframe Adapter for TCP Supported Platforms” for the supported platforms.

Software Requirements

Java Runtime Environment (JRE) 1.7 or 1.8 is required to install Oracle Tuxedo Mainframe Adapter for TCP. You need to install the required JRE and set the environment variable JAVA_HOME accordingly before installing Oracle Tuxedo Mainframe Adapter for TCP.

Temporary Storage Space Requirements

The Oracle Installation program uses a temporary directory in which it extracts the files from the archive that are needed to install Oracle Tuxedo Mainframe Adapter for TCP on the target system. During the installation process, your temporary directory must contain sufficient space to accommodate the compressed Java Runtime Environment (JRE) bundled with the installer and an uncompressed copy of the JRE that is expanded into the temporary directory. The installation program moves the JRE from the temporary directory to the Oracle Home directory at the end of the installation process.

By default, the installation program uses the temporary directories shown in Table 1‑1.

 

Table 1‑1 Temporary Directories

Platform	Directory
UNIX	/tmp

To ensure there is adequate temporary space, you may want to allocate an alternate directory for use as a temporary directory for the installation. To do so, perform the appropriate step in Table 1‑2 and clean up files as more as possible in the temporary directory before starting the Oracle Installation program.

 

Table 1‑2 Perform This Step

On This Platform...	Perform This Step...
UNIX	Enter the following command at the shell prompt: export IATEMPDIR=tmpdirname Replace tmpdirname with the name of a temporary directory of your choice.

Oracle Installation Program

The Oracle Tuxedo Mainframe Adapter for TCP software is distributed as an installer file, which also contains a copy of the Oracle Installation program. The Oracle Installation program is the Oracle standard tool for installing the Oracle Tuxedo Mainframe Adapter for TCP software on UNIX systems.
