Operator Logs
Operator Logs
Operator logs provide a history of problems encountered during each work shift, a
record of unresolved problems, and a record of tasks scheduled and performed or not
performed. The logs help the staff track tasks and determine why problems occur.
Operator logs are maintained by the operators. At each shift change, operators from both
shifts usually sign the operator logs, and the incoming shift usually takes responsibility
for correcting unresolved problems and completing tasks. Operator logs contain
information on:
•
Problems that have occurred, including what the problem is, the time the problem
occurred, error messages or codes, action taken, the results of the problem, a
description of the recovery action taken.
•
Problems that have not been closed and need operation action.
•
Tasks that were scheduled for one shift and completed.
•
Tasks that were scheduled for one shift and not completed.
•
Instructions or information on special conditions for oncoming shifts.
An operator log is usually either a notebook located next to the system console or an
online file. Whichever type of log you use, be sure that the log is always accessible.
Error Logs
An error log is a system-generated hard-copy or online log that contains a record of all
error, warning, and informational messages sent by the system, applications, and
subsystems. Error logs help you track and resolve problems. An example of an error log
is the TSM problem incident report or the NetBatch scheduler log file.
You can use the Event Management Service (EMS) to direct the flow of event messages
to log files or devices. You can use the Event Management Service (EMS) Analyzer to
examine and analyze log files.
CE Logs
When your system is installed, you might receive a site log book that is maintained by
Tandem customer engineers (CEs). The log book contains sections that allow for the
following:
•
System configuration diagrams
•
A preventive-maintenance schedule and contract information
•
Backplane and cable diagrams
•
Service report forms and service reports
•
Floor plans showing the location of system cabinets
•
Equipment inventories
•
Information about whom to contact when questions arise
•
Anything else the CE finds useful
The log book helps you and the CE plan for hardware changes and hardware
maintenance. It is also a good source for reviewing hardware information.
