Reference: note 1513912.1  TFA Collector - Tool for Enhanced Diagnostic Gathering

TFA Collector is installed in the GI HOME and comes with GI and higher.  For GI or lower, install the TFA Collector by referring to <note 1513912.1> for instruction on downloading and installing TFA collector.



This note lists what to collect for different type of Oracle Clusterware and Real Application Cluster issues, it's not mandatory to upload all the files to open a SR, however, it will speed up the resolution if all relevant info are uploaded.

File Formats for Data Uploaded to Oracle Support

Oracle Support requests that you upload compressed files grouped together by node and labeled as such in a standard format, such as .tar, .gz, .Z or .zip.

Older runs of diagcollection or any other files  (i.e. if diagcollection was run a few days or weeks back) may not provide current log information which can delay the resolution.
