file2sm

FILE2SM(1)							  ICI executables							FILE2SM(1)

NAME

       file2sm - shared-memory linked list data ingestion test program

SYNOPSIS

       file2sm fileName

DESCRIPTION

       file2sm stress-tests shared-memory linked list data ingestion by repeatedly writing all text lines of the file named fileName to a shared-
       memory linked list that is the root object of a PSM partition named "file2sm".

       After writing each line to the linked list, file2sm gives a semaphore to indicate that the list is now non-empty.  This is mainly for the
       benefit of the complementary test program sm2file(1).

       The operation of file2sm is cyclical.  After copying all text lines of the source file to the linked list, file2sm appends an EOF line to
       the linked list, containing the text "*** End of the file ***", and prints a brief performance report:

	       Processing I<lineCount> lines per second.

       Then it reopens the source file and starts appending the file's text lines to the linked list again.

EXIT STATUS

       0   file2sm has terminated.

FILES

       No configuration files are needed.

ENVIRONMENT

       No environment variables apply.

DIAGNOSTICS

       Can't attach to shared memory
	   Operating system error.  Check errtext, correct problem, and rerun.

       Can't manage shared memory.
	   PSM error.  Check for earlier diagnostic messages describing the cause of the error; correct problem and rerun.

       Can't create shared memory list.
	   smlist error.  Check for earlier diagnostic messages describing the cause of the error; correct problem and rerun.

       Can't create semaphore.
	   ION system error.  Check for earlier diagnostic messages describing the cause of the error; correct problem and rerun.

       Can't open input file
	   Operating system error.  Check errtext, correct problem, and rerun.

       Can't reopen input file
	   Operating system error.  Check errtext, correct problem, and rerun.

       Can't read from input file
	   Operating system error.  Check errtext, correct problem, and rerun.

       Ran out of memory.
	   Nominal behavior.  sm2file is not extracting data from the linked list quickly enough to prevent it from growing to consume all memory
	   allocated to the test partition.
