Using the SAP Gateway Outside the SAP System

Use

The gateway monitor is used to analyze and administer the SAP Gateway from outside the SAP System.

The profile you assign to it must be the same as for the gateway.

This process has different names:

UNIX: gwmon

Windows: gwmon.exe

Integration

The trace file of the gateway monitor is called: dev_gwmon.

The functionality is the same as that of the SAP Gateway Monitor in the SAP System, the only difference being the menu and submenus.

The detailed information displayed by double-clicking a connection in the SAP system is available here under the Expert Functions.

Features

When you launch the Gateway Monitor without arguments, all of the permitted arguments and options are displayed:

Output Area		Meaning
pf=:	Specify Name of parameter file or System number	Specify the profile file or Specify the number of the system
nr=:
[-V]:	Print release	Output release
[-refresh n]:	Refresh after n seconds	Refresh after n seconds
[-gwhost host]:	Hostname of remote gateway	Host name of the remote gateway
[-gwserv service]:	Service of remote gateway	Service name of the remote gateway
[-expert]	enable expert functions	Enable expert functions
[-sna]	enable sna functions	Enable the SNA functions
[-noheader]	Suppress headers	Suppress headers
[-cmdfile file]	Execute commands from cmdfile if filename '-' read from stdinv	Execute commands from the file. You can display the possible commands, when you enter “-”as the file name and then choose help.

If you start the gateway monitor using the option –sna, you will also see the following output:

[-e all]:	Reset error counts of all connections	Reset error counts for all connections
[-e :	Reset error count of specified connection	Reset error count for the connection with the number

The individual functions are grouped into separate submenus.

Main Menu

When you enter gwmon -gwhost -gwserv , the list of activate connections on the gateway is first displayed. Under this:

q - quit

m - menu

You generally quit the Gateway Monitor with q and use m to go to the (next higher) menu.

If you then enter m and select Return, you will get to the main menu:

Screen output	Meaning
1 : display connection table	Display Active CPI-C Connections
2 : display work process table	Display Gateway Work Processes
3 : display client table	Display the Logged On Systems
4 : display remote gw table	Display Remote Table
5 : connection attributes	Connection Attributes
6 : statistics	Gateway Statistics
7 : gateway parameters and attributes	Displaying Parameters and Attributes of the SAP Gateway
8 : gateway release info	Displaying Gateway Release Information
9 : security information	Display Security Information
10 : expert functions	Expert Functions
+ : increase gateway trace	Increase gateway trace level
- : decrease gateway trace	Decrease gateway trace level
q - quit	Exit Gateway Monitor

Inputs 4,5,7 and 8 lead to submenus that provide functions for the relevant areas.

Activities

To start the gateway monitor, call the corresponding executable file, specifying a profile file:

Under UNIX: gwmon pf=

Under Windows: gwmon.exe pf=

All of the lists are updated after 5 seconds. You can refresh them sooner by pressing Enter.

It is standard to use 50 lines per screen. The number of lines can be changed (for example, under UNIX you can set the shell variable LINES).

Switch command mode

If you use the option -cmdfile , all the functions to be executed are read from the file (see below). If the file name is '-', all the commands from the standard input are read. As a result the monitor can be operated from a program or script to start specific actions or to supply information.

echo GET_CONNTBL | gwmon -cmdfile - -gwhost -gwserv gets the list of active CPIC connections.

The command field interface provides the same functions as the functions from the menu. You can also execute the same function repeatedly.

You can display all the available functions using HELP. If you do not enter anything and choose , the last command is repeated. HELP [command]displays the online help for the command.
