Technical data

If you are unable to analyze a process dump with the debugger, use the System
Dump Analyzer (SDA) utility. Refer to the ANALYZE/CRASH command in online
help for more information. For example:
$ ANALYZE/CRASH billsystem.dmp
OpenVMS (TM) Alpha system dump analyzer
...analyzing a compressed process dump...
Dump taken on 24-JUL-2002 12:03:40.95

For details, refer to the OpenVMS VAX System Dump Analyzer Utility Manual and
the OpenVMS Alpha System Dump Analyzer Utility Manual.
4.4 System Messages
You can keep log files of events, changes, and other configuration data in two ways.
•UsingOPCOM (operator communication manager) — available only if you
have system privileges.
• Using log files that most components establish when they are configured.
System messages are saved to either one of these utilities. Both are described in
this section.
4.4.1 OPCOM
Any terminal that is connected to the operating system can be established as an
operator’s terminal if OPCOM (operator communication manager) is running.
When an operator who is logged in to an account with OPER privilege enters the
REPLY/ENABLE command at the designated terminal, that terminal can be used
to respond to user requests and to monitor device status. Operator messages are
displayed on the system console terminal unless the terminal is explicitly disabled
as an operator’s terminal.
To set up a terminal to receive OPCOM messages, enter the following command:
$ REPLY/ENABLE
4.4.2 Log Files
Event logging can help you manage the TCP/IP Services software. By default,
user-defined services do not log events, but event logging is enabled by default for
all supplied services. You can configure the product to log events to the operator’s
console or to a log file, or to both. Every component has a default log file. For more
information about log files, refer to the Compaq TCP/IP Services for OpenVMS
Management guide.
To set up event logging, enter the following command:
TCPIP> SET SERVICE
service-name /LOG_OPTIONS=ALL
For a list of all the logging options, refer to the SET SERVICE command description
in the Compaq TCP/IP Services for OpenVMS Management Command Reference
manual.
Some product components provide additional event logging capabilities. For more
information, see the relevant chapters in this manual.
