C Oracle Database Gateway Troubleshooting

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

C.1 Verify Requirements

C.2 What to do if an Installation Error Occurs

If you encounter an error during installation:

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:

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:

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:

    1. Select the ORACLE_HOME where the gateway was installed.

    2. Click Remove

    To remove only one instance of the gateway:

    1. Expand the rows in the ORACLE_HOME recursively until you arrive at the folder with the instance to remove.

    2. 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.
