C Oracle Database Gateway Troubleshooting

C.1 Verify Requirements

Before performing any of the troubleshooting steps in this appendix, ensure that the system meets the requirements and that you have completed all of the pre-installation tasks specified in respective chapters.

Read the Release Notes

Read the release notes for the product before installing it. The release notes are available on the Oracle Database 11g Release 2 (11.2) installation media. The latest version of the release notes is also available on the Oracle Technology Network Web site:

http://www.oracle.com/technetwork/indexes/documentation/index.html

C.2 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.

C.3 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 in the oraInventory directory that you specified during installation.

C.4 Silent Mode Response File Error Handling

To determine whether a silent-mode installation succeeds or fails, refer to the following log file:

/oraInventory_location/logs/silentInstalldate_time.log

If necessary, refer to the previous section for information about determining the location of the oraInventory 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 configuration assistant validates the response file at run time. If the validation fails, the silent-mode 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.

C.5 Cleaning Up after a Failed Installation

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

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 the path $ORACLE_HOME/deinstall.

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

Perform the following steps to remove the files:

1. Log in as the installation owner.

2. Run the deinstall command, providing information about your servers as prompted.

3. Reinstall the Oracle software.
