This release updates SYSTAT to increase its reporting facilities to
support the 5.07 Monitor. The external changes made are an extension
of the X option and a facility to get incremental runtime reporting.
The procedure to load SYSTAT has been changed as SYSTAT currently uses
HELPER to print error messages.
2. EXTERNAL CHANGES
2.1 New Commands
The X command has been extended.
A reenter option has been added listing incremental runtimes for jobs.
2.2 Examination of Crashes
The specification of X in the SYSTAT command string caused a SYSTAT
listing to be made of the file CRASH.XPN. Starting with this version
any file for which the user has access rights may be examined.
The format of the X option is:
X [DEV:] [FILE] [.EXT] [PPN]
1. [A] A can occur but does not need to be specified.
2. PPN is the standard DECsystem-10 PPN specification;
If any file is unspecified the following defaults apply:
DEV = DSK
FILE = CRASH
EXT = XPN
PPN = SELF
Note that this extension affects all SYSTAT requests which X was
followed by any other code as the other code might be interpreted as a
Example: .SY XJ
is equivalent to: .SY X DSK:].XPN[SELF]
In previous versions this line would be interpreted as two commands X
and J. (However, the command:
is equivalent to two commands:
1. X CRASH.XPN
2. J list JOB status:
2.3 Incremental Job Data Display
Incremental job runtimes can be displayed by running SYSTAT followed
by a reenter command.
1. The sum of the percentages of CPU time used since the last
pass for all jobs may differ from 100%. This difference can
be due to: e.g., logged out jobs and rounding of the
2. A reenter is equivalent to a SYS command without arguments
giving incremental times instead of total times.
3. KNOWN BUGS AND DEFICIENCIES
1. SY X/F will look for crash file
2. Setting ones path with NOSCAN to another directory and
generating an output disk file will write in the other
3. SY LJE generates an empty file.
4. INSTALLATION INSTRUCTION CHANGES
The installation of SYSTAT has been changed in the following respects:
1. LINK10 is used instead of the loader.
2. The help switch uses a new file SYSTAT.HLP.
3. The HELPER file must be linked with SYSTAT.REL in the low
