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 installation media. The latest version of the release notes is also available on the OTN Web site:

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. Perform the following steps to remove the files:

1. Start Oracle Universal Installer

2. Click Deinstall Products on the Welcome window or click Installed Products on any Installer window.

   The Inventory window appears, listing installed products.

3. Select the Oracle home that contains the products that you want to remove, then click Remove.

4. Manually remove the Oracle home directory created during the failed installation.

5. Reinstall the Oracle software.
