The EBS Technology Codelevel Checker (ETCC) utility provides two scripts you can run to help ensure you have the necessary database and middle tier bugfixes installed on your Oracle E-Business Suite Release 12.2 system. Oracle strongly recommends the use of this utility to ensure that all required database and middle tier bugfixes have been installed.
ETCC can be downloaded via Patch 17537119 from My Oracle Support. As well as installation instructions and basic commands, the README for this patch includes a number of usage scenarios and examples, so should be carefully reviewed before running ETCC.
