Fix 1# View The Interactive Installations
At the time of Oracle 12c database installation, all the actions that are performed in a log file are recorded in Oracle Universal Installer.
In case you face any problem then you can view the log file in order to detect the reason for the error. You can view the log file in the following way:

And to view the log files for interactive Installation
installActionsdate_time.log

Say for example: if an interactive installation was done 8:00:55 a.m. on October 25, 2015, then the log the file will be named as:
installActions2015-10-25_08-00-54AM.log

Sometime you get Oracle 12c database installation error also when the configuration assistant catches any error. You can troubleshoot it in the following ways:
- In order to analysis the installation log files from the list you have to Review the Log of an Installation Session.
- The log file is located in ORACLE_BASEcfgtoollogs Try fixing the issue that causes the error.
- If you get error as “Fatal Error. Reinstall message”, by reviewing the log files look for the reason of the issue. For more information you can see “Irrecoverable Errors’.
Fix 3#Configuration Assistant Failures
At the bottom of the installation window it will display if the Oracle configuration assistant fails. The additional information would be displayed in configuration assistant. You can view the status of configuration assistant execution from the installActionsdate_time.log file. You can view it in the form of table mentioned below:
| Status | Result Code |
| Configuration assistant succeeded | 0 |

| Configuration assistant canceled | -1 |
Fix 4# Irrecoverable Errors
While running configuration assistant if you get an irrecoverable error:
- First you have to remove the failed installation from the system.
- The causes of irrecoverable error should be corrected.
- Now Oracle software has to be reinstalled again.
After restarting your computer, then logon to the Oracle Installation User for Oracle home and then from the path Grid_homecrsconfig run the gridconfig.bat script.
After that to complete the installation or upgrade you have to run configToolAllCommands script which is located in the path ORACLE_HOMEcfgtoollogsconfigToolAllCommands.
Now again restart your computer.
Fix 5# Troubleshooting Host Name Changes and CSS
If you are making changes in the host name of ASM, in that case Oracle CSS daemon won‘t start. To fix this problem, try the following steps:
- For the deconfiguration of CSS, just run the localconfig delete. Doing this will delete any configuration related file present on the system which is referenced with the old host name.
- You have to run the localconfig add in order to reconfigure the CSS with new host name.
For example:
C:> ORACLE_BASEORACLE_HOMEbinlocalconfig [add] [delete]
[reset destination_Oracle_home] [-silent]
[-paramfile Complete_path_of_file_specifying_parameter_values]
Fix 6# Images Displaying Incorrectly in Oracle Application Express
In the “Configuring Oracle HTTP Server in a New Installation”, you must have added the alias entry which is pointing the file system path where you have already copied the images directory.
If the Oracle Application Express image doesn’t appear properly then chances are high that there are more than one definition of the /i/ alias present. To fix this issue, perform the following steps:
- If it is possible, rename the first instance of /i/with some different alias name.
- Or else you can also copy the images from this directory location ORACLE_BASEORACLE_HOMEapeximages into the directory location defined by first /i/
Fix 7# Silent or Response File Installation Error Handling
Another reason because of which you are getting this Oracle 12c database installation error is due to response file installation failure error.
For identification of the response file installation failure or success, please check for the following
silentInstallActionsdate_time.log file, which is located in the directory DRIVE_LETTER:Program FilesOracleInventorylogs .
Mainly this silent installation fails to work in the following circumstances:
- When you haven’t specified the response file.
- Or when the incomplete or wrong response file is specified.
- Chances are also that Oracle Universal Installer catches any error, like insufficient disk space.
Well this Oracle Universal Installer or the configuration assistant validates response file during the runtime. If the validation process fails to work then it will automatically end up the configuration or installation process also.
