C Oracle Database Gateway Troubleshooting

This appendix contains information about troubleshooting. It includes the following topics:

• Verify Requirements

• What to do if an Installation Error Occurs

• Reviewing the Log of an Installation Session

• Noninteractive Installation Response for File Error Handling

• Cleaning Up after a Failed Installation

C.1 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:

  http://www.oracle.com/technology/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 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

Note: Do not delete or manually alter the Inventory directory or its contents. Doing so can prevent Oracle Universal Installer from locating products that you install on your system

C.3.1 Fatal Errors

If you receive a fatal error while a configuration assistant is running then:

• Remove the failed installation as described in the Cleaning Up after a Failed Installation section.

• Correct the cause of the fatal error.

• Reinstall the Oracle software.

C.4 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.

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. Follow the instructions below to run Oracle Universal Installer to remove the gateway, manually remove the Oracle directory, and remove Oracle from the Registry Editor keys. Then, reinstall the software:

1. Insert the gateway product installation media.

2. Start the Oracle Universal Installer by running isetup.exe from the installation disk the Oracle Universal Installer directory.

3. Go through the steps in the Oracle Universal Installer. Use the table, Steps to Remove the Gateway Using Oracle Universal Installer, below as a guide for selecting the correct options to remove the gateway.

   Table C-1 Steps to Remove the Gateway Using Oracle Universal Installer

   Prompt	Response
   Oracle Universal Installer: Welcome	Click Deinstall Products
   Inventory	You may either choose to remove all products that you may have installed at the time of your original gateway installation, or you may choose to remove only an instance of the gateway. To remove all products: Select the ORACLE_HOME where the gateway was installed. Click Remove To remove only one instance of the gateway: Expand the rows in the ORACLE_HOME recursively until you arrive at the folder with the instance to remove. Click Remove
   Confirmation	Click Yes.
   Inventory	Click Close.
   Oracle Universal Installer: Welcome	Click Cancel.
   Exit	Click Yes.

   
   

4. The gateway is now removed.

   When the Oracle Universal Installer confirms that the deinstallation has ended, verify that the removal procedure was successful. To do this, read the contents of the deinstallation log file, which is located in the C:\Program Files\Oracle\Inventory\logs directory.

   The default file name is InstallActionsYYYY-MM-DD_HH-mm-SS-AM/PM.log, where:

   • YYYY is year

   • MM is month

   • DD is day

   • HH is hour

   • mm is minute

   • SS is seconds

   • AM/PM is daytime or evening

   These variables in the log file name represent the date and time the product was deinstalled.

5. The only files that are removed are those that were copied to the ORACLE_HOME directory during the gateway installation. You must remove any other related files manually, including deleting listener.ora and tnsnames.ora entries relating to the gateway, dropping database links.
