Object documentationSAPOSCOL Log Files

 

The following files for the function of SAPOSCOL are stored in the Working Directory of SAPOSCOL:

  • The file coll.put, in which SAPOSCOL writes the contents of its shared memory segment; this is performed only when SAPOSCOL is stopped and at user command

  • The configuration file for monitoring selected processes, dev_proc (see Monitoring Selected Processes with SAPOSCOL)

  • The file dev_filter that contains the file systems and hard disks that are not to be monitored by SAPOSCOL (see Deactivating Object Monitoring by SAPOSCOL)

  • The log file dev_coll that contains SAPOSCOL messages and the status of SAPOSCOL

    Note Note

    During error analysis of SAPOSCOL, you should also check the file dev_coll.

    End of the note.

  • The log files dev_col1 and dev_col2, which are written with a cyclical trace when SAPOSCOL is started (command saposcol –z, see Controlling SAPOSCOL from the Operating System)

    Note Note

    With the cyclical trace, the trace information alternately to the files dev_col1 and dev_col2:

    • The trace is first written in the file dev_col1

    • · When dev_col1 exceeds a set size, the trace is written to dev_col2. The size is 50,000 lines. This number is not configurable.

    • · When dev_col2 exceeds this size, dev_col1 is deleted and the trace is written to this file again.

    This process is continuous. This ensures that the current trace is always accessible, without a trace file being able to grow to any size.

    End of the note.
