MPE SYSTEM LOGFILE RECORD FORMATS

This document describes the record formats for HP 3000 system log files for both MPE IV and V. The details of system logging are discussed in Chapter 5 of the System Operation and Resource Management Reference Manual (P/N 32033-90005) - for MPE V/E systems or Chapter 6 of the MPE IV System Manager/System Supervisor Reference Manual (P/N 30000-90014) - for MPE IV and V/P.

The formats of most type of records are the same under MPE IV and MPE V. However, beginning with MPE V/E, a few changes were made primarily to accomodate the new larger PIN and LDEV number fields. In addition, the TYPE 4 record was enhanced to include PIN and CPU TIME fields.

INTRODUCTION

Log records are written to log files by MPE. This is done by calls to an internal procedure by the process that requires the recording of a particular event. The log records can by subsequently accessed, manipulated, and displayed through user-supplied analysis routines.

There are 21 types of log records that can be generated:

TYPE DESCRIPTION
0 Log Failure Record
1 System Up Record
2 Job Initiation Record
3 Job Termination Record
4 Process Termination Record
5 File Close Record
6 System Shutdown Record
7 Power Failure Record
8 Spoolfile Done Record
9 Line Disconnection Record
10Line Close Record
11I/O Error Record
12Physical Mount/Dismount Record
13Logical Mount/Dismount Record
14Tape Labels Record
15Console Log Record
16Program File Event Record
17Call Progress Signals Record
18DCE Provided Info Record
46MPE Maintenance Request Log Record
47Diagnostic Control Unit Log Record

Log records, although different in format, length, and content, always have the same heading:

Field Length (words)Contents
1Record Type
1Record Length
3Time Stamp
(As defined in the CLOCK and CALENDAR intrinsic
1
0Job Type1 2Job Number15


RECORD TYPE Defines the record as one of the 21 types listed before

RECORD LENGTH Defines the number of words that the record contains

TIME STAMP Date and time, in the same format used by the CLOCK and CALENDAR intrinsics, as shown below

JOB TYPE Type of main process being run, where bits 0 and 1 have the following meaning:
  00 = System
  01 = Session
  10 = Job
JOB NUMBER Number defining the job/session under which the log record has been output. If the last word is 0, this means that the record is related to the system and was not output for a user.

The TIME STAMP field as described above looks like this:

0Year (last 2 digits)6 7Day of Year15
0Hours7 8Minutes15
0Seconds7 8Tenth-of-Second15


DETAILED RECORD FORMATS

The remainder of this document describes each of the different record formats. When the MPE V and MPE IV formats differ, each is shown.

01 = SESSION - Spoolfile created for a session on this system
10 = JOB - Spoolfile created for a job on this system
11 = JOB - Spoolfile originally created on another system by a job

Note: For job types 00 and 11, SPOOK was used to create the spoolfile on this system.

For Output spoolfiles - the logical device number of the printer used

NUMCOPIES (1 byte) Number of copies that are yet to be printed for this spoolfile. For multiple copy spoolfiles, this number is decremented after each copy has been printed and a different spooling logging record exists for each copy printed. If there is only one copy to be printed, the field is 0.

# PHYSICAL PAGES
(2 words)

 Total number of physical pages printed

# LP/PP (6 bits) If the spoolfile is using a LPX type environment file, this field is defined as the number of logical pages per physical page when the spoolfile ended. NOTE: THIS VALUE CAN CHANGE WHILE THE SPOOLFILE IS PRINTING.

JOB TYPE/JOB NUMBER
(1 word)

 Type and number of job/session

ERROR INDEX WORD
(1 word)		 First byte is number of error status words logged.
Second byte is Device Information Table relative index to words logged.

Description of bit flags in Word 8 All are single bit fields (except T, which is 2 bits long).
A "1" in any single bit field indicates:

A   (ABORT) Request has been aborted externally

S   (SPECIAL) Special handling is to be applied to this request; for disc this indicates a Memory Management request

D   (DIAG) Diagnostic request (not used)

Y   (SYSBUFR) Indicates the target data segment is irrelevant; the target data address is the absolute main memory address of the buffer

W   (IOWAKE) Wake caller on completion of request

B   (BLOCKED) Blocked I/O; caller is waited until request is completed

C   (COMPLETED) Request has been completed and caller is awake if he had so specified

F   (DATAFRZN) Data segment has been made present and is frozen

M   (MEMERRORD) MAM error on data segment make-present

P   (PREQ) This request has been started but was preempted by a MAM request

L   (SFAIL) Start SIO failure in General Interrupt Processor

R   (PFAIL) The I/O has been aborted because of a power failure

T   (PREEMPT) Preemptive type code: l=soft, 2=hard

G   (MSGDONE) A message request reply has been completed

DRIVER FUNCTION CODE Generally a number indicating a particular driver action, such as: 0 = read; 1= write

TRANSMISSION COUNT
(1 word)		 Final transfer count (if any) for this I/O request. If positive, it indicates words; if negative, it indicates a byte count

DRIVER PARAMETER 1
(1 word)

 Defined within the I/O system for various drivers

DRIVER PARAMETER 2
(1 word)

 Defined within the I/O system for various drivers

PROCESS PCB NUMBER
 Is zero if not associated with a user process

STAT (3 bits) Indicates current and resultant state of the request:
0 = Not started, or awaiting completion
1 = Successful completion
2 = End of file detected
3 = Unusual condition (normally recoverable)
4 = Irrecoverable error
Note: The PROCESS PCB NUMBER, HARDWARE UNIT NUMBER, and DRT NUMBER fields are 1 word long on MPE V systems, but only 1 byte on MPE IV systems. Likewise, the DRIVER FUNCTION CODE is only 1 byte long on MPE V systems, but 1 word long on MPE IV systems.

Therefore, the record length is (21 + the number of status words logged) - on MPE V systems or (19 + the number of status words logged) - on MPE IV systems.

Note: If EVENT TYPE = 0 (Stack Underflow Recovery), DELTA P and STATUS are not applicable.

Currently, the only defined Program File Event is 0, Stack Underflow Recovery. In general, this occurs because a program uses outmoded constructs, emitted by earlier versions of compilers, which are trapped and "manually" executed by system software. Recompiling such a program with a current compiler will correct the problem.
