Function

Use

Load balance table

Displays the load balancing table when Load Balancing for Registered Programs is in use.

Read side info file

Displays the side info file used by the gateway. This file is set with the profile parameter gw/sideinfo (see Parameterization of the SAP Gateway) (default /usr/sap/<SID>/<INSTANCE>/data/sideinfo). The contents of the file are simply displayed as a list.

For details see Side Information Tables.

Memory allocation

This function is only relevant for monitoring an SNA gateway (Goto ® Gateway ® SNA Gateway).

The current memory allocation (that is, all locked request blocks) is displayed. The number of each request block and the process which is currently using it are also displayed.

Network addresses

Displays all network addresses of the current host. Also tells you where the names were taken from.

Host name buffer

The host name buffer buffers the assignments of IP addresses to host names. This enhances performance during connection establishment.

This function can display the host name buffer, write it to a file, or reset it.

Statistics

Allows you to check the performance of the SAP Gateway. You can activate and deactivate these statistics dynamically. Resetting the statistics causes all the data currently gathered to be deleted and the statistics to be deactivated.

To call up the statistics functions, choose Goto ® Expert functions ®  Statistics. You can display, activate, deactivate, or reset the statistics.

The statistics display includes the following values:

·         Timeout count

·         Request block overflow count

·         Request count (read and work processes)

·         Total request time (read and work processes)

·         Time per request (minimum, mean, maximum for read and work processes)

·         Longest request (read process)

·         TCP statistics

·         CPI-C statistics

External security

Here, you can:

·         Display the security files secinfo and reginfo

·         Read the security files again

This allows the security information to be modified during the runtime of the gateway.

For more information see Security Measures for the SAP Gateway.

Started programs

Displays the list of started programs (see the parameter description for gw/startup in Parameterization of the SAP Gateway).

GW WP status

Here details of the gateway connection for each work process are displayed (see Displaying and Managing Work Processes).

List of the Conversation IDs

Includes all conversation IDs managed by the gateway - conversation IDs generated by other gateways that communicate with the local gateway, as well as conversation IDs generated by the local gateway.

·        local, conn=nn means this conversation ID was created by the local gateway and is assigned to the connection with the number nn. You can see this conversation ID in the list of active connections (initial screen of SMGW).

·        remote, host / serv (gw_id=xx) means this conversation ID was created by the remote gateway on the host <host>, service <serv>. This remote gateway is listed in the 'remote gateways' list under number xx (Displaying Remote Gateways).

Soft Shutdown

Soft shutdown terminates the gateway – the gateway accepts no new connections and closes as soon as there are no more active connections.

Hard Shutdown

The hard shutdown terminates the gateway immediately (no  checks made).
