Here is a quick guide to enable Image logging on your MNT (C.00.01D) application. To learn more about Image logging, see
your HP manual, "TurboIMAGE/XL Database Management System Reference Manual" PN 30391-90001 E0897, chapter 7
Logging and Recovery. For the MNT application, see "Maintenance Management Guide to System Implementation and
Maintenance", chapter 2 Databases (page 2-12 to 2-17) and chapter 7 System-Values.

The MPE commands used for user logging are:

GETLOG    

get a logging identifier (LOGID)

  SHOWLOGSTATUS   

show active user logging by LOGID

ALTLOG    

change attributes of a LOGID

   CHANGELOG       

force a log file change in user logging

LISTLOG   

list attributes of LOGIDs

       LOG             

start/stop/restart user logging

RELLOG    

release a LOGID

You need to choose appropriate names and values for the bold, underlined examples in these commands.
1. Get a LOGID. If you select autochange your filename must end with "001".

  :GETLOG MNT;LOGMN001,DISC;AUTO;PASSWORD=LOGPASS

2. Create the initial log file

  :BUILD LOGMN001;code=log;disc=200000

3. Enable your databases for logging

  :RUN DBUTIL.PUB.SYS
  >>SET ECATDB LOGID=MNT
     password: LOGPASS
  >>ENA ECATDB FOR LOGGING                  (repeat for PCATDB,PICDB,WOCDB)
  >>EXIT

4. Start user logging.

  :LOG MNT, START

When doing backup or system shutdown, you must stop user logging with the STOP option. If you need to interrupt the
current logging cycle, after STOP, you can use the RESTART option to continue with the current log file.

Your MNT application should now be logging. With the SHOWLOGSTATUS command you can see the current status of the
log file. With the auto option, when the log file gets full, the next log file in numeric sequence will be built and logging will
switch to the new file. Without the auto option or at anytime you choose, you can use the CHANGELOG command to switch
to a new log file.

Now you must change the following system values to "Y", otherwise you the application will abort with Image error -110
LOGGING ENABLED AND NO LOG PROCESS RUNNING.

        System-Value:  LOG-ECATDB,  LOG-WOCDB,  LOG-PCATDB,  LOG-PICDB

Don't forget to PREP DICTIONARY !

To turn logging back off, change system values to "N", stop logging: LOG MNT,STOP, and disable the databases for logging
with DBUTIL: >>DIS ECATDB FOR LOGGING, etc.

Example logging scenarios, reporting/analyzing log files, and database recovery are topics for future lab notes.
