After completing the installation of Oracle HTTP Server 11g Webgate for Oracle Access Manager, including the post-installation steps, you can examine the installDATE-TIME_STAMP.out log file to verify the installation.
On UNIX systems, if you do not know the location of your Oracle Inventory directory, you can find it in the <Webgate_Home>/oraInst.loc file.
On Microsoft Windows systems, the default location for the inventory directory is C:\Program Files\Oracle\Inventory\logs.
