by Oracle Trace File Analyzer helps you perform real-time health monitoring, fault detection & diagnosis via a single interface. It will securely consolidate all distributed diagnostic data. TFA can be installed on the database nodes either stand alone or cluster nodes. It’s continuously available and watching your logs for significant problems that may affect your service. If desired it can also automatically collect the relevant diagnostics, when it sees these problems.
From 12.2, TFA is included with RDBMS software and again this is optional when we run the root.sh script. You can skip this if you don’t want.
