Oracle HSM (SAM-QFS): How to Turn File System Tracing (samtrace) On or Off
Last updated on DECEMBER 02, 2016
Applies to:Oracle Hierarchical Storage Manager (HSM) and StorageTek QFS Software - Version 3.5 and later
All SAM-FS and QFS mounted file systems log their trace output in a trace buffer when file system tracing is turned on. These traces are useful to troubleshoot and resolve file system related problems.
Turning off SAM-FS file system tracing can improve performance of the mounted file systems.
Don't get confused between file system tracing and daemon tracing. SAM-FS daemon tracing can be turned on or off via changes applied to the defaults.conf file and is not discussed in this document.
For more details on how to enable SAM-QFS daemon tracing consult Document ID 1010462.1
The remainder of this document discusses methods of turning file system tracing on or off.
