Videos: Working with the Trace File Analyzer Collector

The Trace File Analyzer (TFA) Collector Tool is a utility for collecting first failure diagnostics when creating Service Requests with Oracle Support. Using TFA Collector to make diagnostic collections removes questions about what files to collect and upload. TFA knows about all the well known Oracle and operating system diagnostic locations and collects only files that have been modified proximate to problem time specified from any of those
well known locations. Larger files are also pruned proximate to problem time specified to reduce the size of the upload. If the system is a clustered environment TFA collects relevant diagnostics from the remote nodes as well. All of this can be accomplished with one simple command.
Key features of TFA Collector include: RAC and single instance non-RAC support Time-based collection of relevant files OS Clusterware ASM DB OSW and CHMOS etc Large file pruning Cluster-wide time-relevant collections Analytics for key files DB alert logs Clusterware alert logs ASM alert logs system messages OSWatcher top and slabinfo data Flexible command-line interface
