TFA Collector工具是一个诊断收集工具，用来简化Clusterware/Grid Infrastructure/RAC/Single Instance数据库系统诊断数据收集，关于MOS对TFA说明：
Trace File Analyzer Collector (TFA) is a diagnostic collection utility to simplify diagnostic data collection on Oracle Clusterware/Grid Infrastructure, RAC and Single Instance Database systems. TFA is similar to the diagcollection utility packaged with Oracle Clusterware in the fact that it collects and packages diagnostic data however TFA is MUCH more powerful than diagcollection with its ability to centralize and automate the collection of diagnostic information. TFA provides the following key benefits:

1)Increase Productivity with Reduction in time and effort in diagnostic collection
    Diagnostic collection is performed with a single command executed from a single node
    Diagnostics collected include log and trace files for Grid Infrastructure/Oracle Clusterware, ASM, RAC and the OS
    Output is consolidated to a single node for ease of upload
2)Reduce diagnostic data uploads to support by a factor of 10x or morein most cases
    Diagnostic files are isolated and trimmed to only include data for incident time
3)Reduce SR Resolution times
    Proper diagnostics collection for incidents ensure complete diagnostic data collections thus minimizing the need for support to request additional data
4)Ensure that proper Diagnostic Tools are in place to better deal with Reactive types of issues
