How can Code Tester's Oracle home be set without opening the Code Tester application?

The default OracleHome, when set to something other than the default, is stored in the QuestCodeTesterOracle.ini file. Therefore, this file can be manually edited to add the OracleHome entry set to their desired oracle home. If the ini file does not exist, create it using notepad or another editor.'
