C Oracle Database Gateway Troubleshooting

Verify Requirements

• Check the system requirements section of respective gateway installation chapters to ensure that the system meets the requirements and that you have completed all the preinstallation tasks.

• Read the release notes for the product on your platform before installing it. The release notes are available on the Oracle software installation media. You can find the latest version of the release notes on the Oracle Technology Network Web site:

What to do if an Installation Error Occurs

If you encounter an error during installation:

• Do not exit Oracle Universal Installer.

• If you clicked Next after you entered incorrect information on one of the installation screens, click Back to return to the screen and correct the information.

• If you encounter an error while Oracle Universal Installer is copying or linking files, refer to the Reviewing the Log of an Installation Session section.

• If you cannot resolve the problem, remove the failed installation by following the steps listed in the Cleaning Up after a Failed Installation section.

Reviewing the Log of an Installation Session

During an installation, Oracle Universal Installer records all of the actions that it performs in a log file. If you encounter problems during the installation, review the log file for information about possible causes of the problem. The log file is located in SYSTEM_DRIVE:\Program Files\Oracle\Inventory\logs.

Log file names take the form:

installActionsdate_time.log

For example, if the installation occurred at 9:00:56 A.M. on May 14, 2004, then the log file would be named:

installActions2004-05-14_09-00-56-am.log

Noninteractive Installation Response for File Error Handling

To determine whether a noninteractive installation succeeded or failed, check the installActionsdate_time.log file, located in SYSTEM_DRIVE:\Program Files\Oracle\Inventory\logs.

If necessary, then see the previous section for information about determining the location of the Inventory directory.

A silent installation fails if:

• You do not specify a response file.

• You specify an incorrect or incomplete response file.

• Oracle Universal Installer encounters an error, such as insufficient disk space.

Oracle Universal Installer or a configuration assistant validates the response file at run time. If the validation fails, then the noninteractive installation or configuration process ends. Oracle Universal Installer treats values for parameters that are of the wrong context, format, or type as if no value was specified in the file.

Cleaning Up after a Failed Installation

The Deinstallation Tool (deinstall) is available in the installation media before installation, and is available in Oracle home directories after installation. It is located in ORACLE_HOME\deinstall.

The deinstall command stops Oracle software, and removes Oracle software and configuration files on the operating system.

If an installation fails, you must remove files that Oracle Universal Installer created during the attempted installation and remove the Oracle home directory. Follow the instructions below to remove the gateway.

1. Log in as a member of the Administrators group.

2. Run the deinstall command, providing information about the Oracle System Identifier (SID), when prompted.

3. Reinstall the software.
