Use

You use this procedure to set global service parameters in ITS Administration. Any parameters set in the global service file apply to all services unless overridden by values in service-specific service files.

To optimize ITS performance, you can set values for the parameters listed in the table below:

Parameter

Description

~runtimeMode

Runtime mode for system template handling.

The ITS supports two runtime modes:

  • Production mode (pm)

System templates in production mode contain more generic messages intended for users of production systems.
  • Development mode (dm)

System templates in development mode contain more detailed messages to support developers working in development and test systems who need to identify problems and find solutions.

You should set ~runtimeMode to pm in production systems.

~http_use_compression

Enables / disables HTTP compression.

To reduce the size of data sent from the Web server to the Web browser and increase transmission speeds, you can use HTTP compression.

To enable HTTP compression, you must set this parameter to 1. You can then set the compression level by specifying a value for ~http_compress_level (see below).

~http_compress_level

Level of HTTP compression.

If you enable HTTP compression by setting ~http_use_compression to 1, you can use this parameter to specify a compression level from 1 to 9, where 1 is the lowest compression level and 9 is the highest level.

The higher the value you set for ~http_compress_level, the better the compression you achieve, but this is at the expense of processing speed:

  • Level 1 achieves lowest compression level / fastest processing speed
  • Level 9 achieves highest compression level / slowest processing speed

The operation of ~http_compress_level depends on the value of ~http_use_compression :

  • If ~http_use_compression is set to 1 , you can set ~http_compress_level to any value between 1 and 9
  • If ~http_use_compression is set to 1 , but you do not set a value for ~http_compress_level , the ITS sets a default value of 7
  • If ~http_use_compression is set to 0 or is not present, the ITS ignores any value you set for ~http_compress_level

With the SAP GUI for HTML, for example, a compression level of 7 typically achieves compression rates of approximately 70%, with no appreciable improvement for higher compression levels.

~timeout

User session timeout.

This is the time in minutes from the last request during a user session until that session is automatically terminated.

When the period specified in ~timeout has expired, the user context (client, user, and password) can be retained for a period specified by the parameter ~userTimeout (see below).

In the interests of security, you should keep both the value of ~timeout and ~userTimeout low. How low depends on the security arrangements at your installation.

~userTimeout

User context timeout.

This is the time in hours that a user context (client, user name, and password) is retained after the session timeout period specified by the parameter ~timeout (see above) has expired:

  • If the user logs on again before the time defined by ~userTimeout has expired, the ITS uses the previously established user context, so the user does not have to re-enter logon information
  • If the time defined by ~userTimeout has expired, the previously established user context no longer exists, so the ITS requests the user to enter logon information again

Prior to Release 4.6B, ~userTimeout was measured in minutes.

In the interests of security, you should keep both the value of ~userTimeout and ~timeout low. How low depends on the security arrangements at your installation.

Prerequisites

You have started ITS Administration.

Procedure

  1. Select an ITS instance and choose an AGate server hosted at the local machine.
  1. Choose Configuration.
  2. Choose Global Services.
  3. Choose All Settings.

You see a screen that lists the current settings for all global service parameters.

This graphic is explained in the accompanying text
  1. Set values for all the parameters listed in the table above:
  1. Save your changes.

Result

ITS Administration automatically updates the values in the global service file. You do not have to restart the ITS instance to activate your changes.

Note

Defining data compression for all services by setting the ~http_use_compression and ~http_compression_level parameters in the global service file may impair performance. Sometimes, it is better to compress data only for selected services by setting these parameters in the relevant service file(s).
