psmwatch - PSM memory partition activity monitor SYNOPSIS
psmwatch shared_memory_key memory_size partition_name interval count [ verbose ] DESCRIPTION
For count interations, psmwatch sleeps interval seconds and then invokes the psm_print_trace() function (see psm(3)) to report on PSM dynamic memory management activity in the PSM-managed shared memory partition identified by shared_memory_key during that interval. If the optional verbose parameter is specified, the printed PSM activity trace will be verbose as described in psm(3). To prevent confusion, the specified memory_size and partition_name are compared to those declared when this shared memory partition was initially managed; if they don't match, psmwatch immediately terminates. If interval is zero, psmwatch merely prints a current usage summary for the indicated shared-memory partition and terminates. psmwatch is helpful for detecting and diagnosing memory leaks. EXIT STATUS
0 psmwatch has terminated. FILES
No configuration files are needed. ENVIRONMENT
No environment variables apply. DIAGNOSTICS
The following diagnostics may be issued to the ion.log log file: Can't attach to psm. ION system error. One possible cause is that ION has not yet been initialized on the local computer; run ionadmin(1) to correct this. Can't start trace. Insufficient ION working memory to contain trace information. Reinitialize ION with more memory. BUGS

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. BUGS
