In this post I will explain how We can install and use TFA. Oracle Trace File Analyzer (TFA) provides a number of diagnostic tools in a single bundle, making it easy to gather diagnostic information about the Oracle database and clusterware, which in turn helps with problem resolution when dealing with Oracle Support.
In many case Oracle will some output using this tool for your Service Requests.
First We need to download latest TFA version from Metalink. Please follow TFA Collector – TFA with Database Support Tools Bundle (Doc ID 1513912.1)
