Troubleshooting the SLSA Subsystem

an integer in the range 4 through 1024 or is equal to 0. If PAGES is omitted or if <pages> is

equal to 0, the default value of 64 pages is used.

<size> is the length of the data in the trace-data records. You can specify <size> as 0 or as

an integer in the range 16 through 4050. The length of the trace header, which is 8 bytes, is

not included in <size>. If RECSIZE is omitted or if <size> is equal to 0, a default value of

120 bytes is used.

<select-spec> is one of the following specifications:

{ <keyword> }

{ ( <keyword> [ , <keyword> ] ... ) }

{ <number> }

{ ( <number> [ , <number> ] ... ) }

<keyword> is a subsystem-specific keyword. ALL is the only keyword that can

be used for the PROCESS object. See <select-spec> for MON Object,

<select-spec> for PIF Object, and <select-spec> for SAC Object for keywords

for the MON, PIF, and SAC objects.

<number> is the numeric value that a keyword represents. -1 is the only

number that can be used for the PROCESS object. See <select-spec> for MON

Object, <select-spec> for PIF Object, and <select-spec> for SAC Object for

keywords for the MON, PIF, and SAC objects.

<file-spec> is the file to which trace information will be written. The file might have been

previously created as an unstructured file with file code 830. An old file is purged of data

before the trace is initiated. If the file does not exist, a file is created with an extent size

based on the number of pages in the PAGES option.

WRAP specifies that when the trace disk file end-of-file (EOF) is reached, trace data wraps

around to the beginning of the file and overwrites any data there.
