The Monitor Client NATMOPI is a character-based command
interface for monitoring the various types of servers that are provided in a
mainframe Natural environment. Each of these servers has its own set of monitor
commands which is described in the corresponding server documentation. In
addition, a set of directory commands is available which can be used
independent of the server type. One NATMOPI can be used to monitor
different server types.
Basically the syntax of the command interface consists of a list of options where each option can/must have a value. For example:
-s <server-id> -c help
where -s and -c are options and
<server-id> and help are the option
values.
It is possible to specify multiple options, but each option can have only one value assigned.
The command options available are listed below.
Words enclosed in <> are user supplied values.
| Command Option | Action |
|---|---|
-s
<server-id> |
Specify a server ID for sending a
monitor command. If the server
ID is not unique in the server directory, NATMOPI prompts the user
to select a server.
|
-c <monitor
command> |
Specify a monitor
command to be sent to the server ID defined with the
-s option
|
-d <directory
command> |
Specify a directory command to be executed. |
-a |
Suppress prompting for ambiguous server ID. Process all servers which apply to the specified server ID. |
-h |
Print NATMOPI help.
|
These are commands that are sent to a server for execution. The monitor
commands available depend on the type of server, however, each server is able
to support at least the commands ping,
terminate, and help.
For further commands, refer to Operating the Natural SQL Gateway Server where the corresponding server commands are described.
Directory commands are not executed by a server, but directly by the
monitor client NATMOPI.
You can use the directory commands to browse through the existing server entries and to remove stuck entries.
The following directory commands are available. Words enclosed in
<> are user supplied values and words enclosed in straight
brackets [] are optional.
| Directory Command | Action |
|---|---|
ls
[<server-id>] |
List all servers from the server directory that apply to the specified server ID. The server list is in short form. |
ll
[<server-id>] |
Same as ls, but the server list
contains extended server information.
|
rs
[<server-id>] |
Remove server entries from server directory.
Note: |
cl
[<server-id>] |
Clean up server directory. This command pings the specified server. If the server does not respond, its entry will be removed from the directory. |
ds |
Dump the content of the server directory. |
lm |
List pending IPC messages. |
natmopi -dls |
List all servers registered in the directory in short format. |
natmopi -dcl TST -ls TST |
Clean up all servers with ID TST* (ping server and
remove it, if it does not respond), and list all servers with ID
TST* after cleanup.
|
natmopi -sSRV1 -cping -sSRV2 -sSRV3 -cterminate |
Send command ping to
SRV1. Send command terminate to
SRV2 and SRV3.
|
natmopi -cterminate -sSRV1 -cping -sSRV2 -sSRV3 |
Is equivalent to the previous example. That is,
NATMOPI sends the command following the
-s option to the server. If no
-c option follows the -s
option, the first -c option from the command line
will be used.
|
natmopi -sSRV1 -cterminate -a |
Send command terminate to
SRV1. If SRV1 is ambiguous in the server directory,
send the command to all SRV1 servers without prompting for
selection.
