In the following configuration description, ETB255 is the name of a Broker and NATWEB1 the name of an RPC Server used for the examples.
For the installation and configuration, refer to the Natural RPC, Entire Net-Work, and EntireX Communicator documentation.
The following topics are documented below:
ACIVERS Settings
You are recommended to set the profile parameter ACIVERS to a value of 6 or above. Refer to Set the ACI Version in the Natural RPC documentation for further details.
MAXBUFF and MAX-MESSAGE-LENGTH Settings
You are recommended to set the profile parameter MAXBUFF on the Natural RPC server to a value of 1024 or above. This also requires setting the value of MAX-MESSAGE-LENGTH to 1048576 or above on the EntireX Broker that is included in EntireX Communicator.
To change your NATPARM file so that two additional steplibs can be accessed in the RPC environment:
In the Natural Execution Configuration parameter group, add the two steplibs SYSWEB and SYSEXT to the steplib parameter subsection.
To change your NATPARM file so that two additional steplibs can be accessed in the RPC environment:
In the Natural Execution Configuration parameter group, add the two steplibs SYSWEB3 and SYSEXT to the steplib parameter subsection.
If Natural Security is installed:
Define the steplibs SYSWEB and SYSEXT for your library.
If Natural Security is not installed:
Modify the Natural program WEB-STLB in library SYSWEB by entering the DBID and file number of the associated FNAT system file of the libraries SYSWEB and SYSEXT. If required, you can add additional steplibs.
STOW the program.
The STACK parameter for your RPC server should have the following
value: STACK=(LOGON SYSWEB;WEB-STLB)
Setting the environment variables is not required.
All EntireX-relevant environment variables must be passed by the HTTP server.
To install and configure the DCOM server, proceed as described in the NaturalX documentation.
In the following configuration description, NATWEBEXT is the name of an external DCOM Server and NATWEB is the name of a local DCOM Server.
This section covers the following topics:
For all servers supporting the Natural Web Interface, add the libraries SYSWEB3 (or SYSWEB) and SYSEXT as steplibs, as described above in the section Current Version of Natural for Mainframes, UNIX or Windows.
The following topics are covered below:
For mainframe, Windows and UNIX environments no configuration is required.
Adjust the configuration file using an external editor:
RPC_ETB_ID_NAME=ETB255 RPC_SERVER_NAME=NATWEB1
The parameter NWW_OUT_CSS_TRANSLATE must be set in the
Configuration File. Its value depends on the code page used.
No adjustments are required for local communication.
External DCOM (All Platforms)
For external communication, see the NaturalX documentation for registry changes, or adjust the configuration file using an external editor:
DCOM_SERVER_NAME=NATWEBEXT
On Windows (Internet Information Server)
If you use the Internet Information Server, the username for anonymous logon, e.g. NATWEB, is used. NATWEB must belong to the group USER, or the GUEST account must be enabled.
If you use the Apache Server, the default settings for User/Group specified at httpd.conf can be used:
# User/Group: The name (or # number) of the user/group to run httpd as User nobody Group #-1
Note:
This section applies to SYSWEB3 only.
Install the Natural Web Server Extensions
Open the ..\conf\httpd.conf file of the HTTP Server
and add the the following new lines for the RPC Interface:
... LoadModule nww3_module modules/nww3mod2.dll <Location /nww3/mod> AllowOverride None NWWiniFile "<yourRoot>/nww3/nww3mod.ini" SetHandler nww3 </Location> ...
... LoadModule nww3_module modules/nww3mod22.dll <Location /nww3/mod> AllowOverride None NWWiniFile "<yourRoot>/nww3/nww3mod.ini" SetHandler nww3 </Location> ...
Specify additional files at the /nww3 directory, if
not only one service or broker are to be used.
If a static read of the .ini file is wanted (this influences the
performance), add the line shown in italics to your
obj.conf.
Install the Natural Web Server Extensions.
Open the ..\conf\httpd.conf file of the HTTP Server
and add the the following new lines for the DCOM Interface:
... LoadModule nww3d_module modules/nww3dmod2.dll <Location /nww3d/mod> AllowOverride None NWWiniFile "<yourRoot>/nww3d/nww3dmod.ini" SetHandler nww3d </Location> ...
... LoadModule nww3d_module modules/nww3dmod22.dll <Location /nww3d/mod> AllowOverride None NWWiniFile "<yourRoot>/nww3d/nww3dmod.ini" SetHandler nww3d </Location> ...
Specify additional files at the /nww3d directory, if
not only one service or broker are to be used.
If a static read of the .ini file is wanted (this influences the
performance), add the line shown in italics to your
obj.conf.
Install the Natural Web Server Extensions.
Open the ..\conf\httpd.conf file of the HTTP Server
and add the the following new lines for the SPoD (PAL) Interface:
... LoadModule nww3p_module modules/nww3pmod2.dll <Location /nww3p/mod> AllowOverride None NWWiniFile "<yourRoot>/nww3p/nww3pmod.ini" SetHandler nww3p </Location> ...
... LoadModule nww3p_module modules/nww3pmod22.dll <Location /nww3p/mod> AllowOverride None NWWiniFile "<yourRoot>/nww3p/nww3pmod.ini" SetHandler nww3p </Location> ...
Specify additional files at the /nww3p directory, if
not only one service or broker are to be used.
If a static read of the .ini file is wanted (this influences the
performance), add the line shown in italics to your
obj.conf.
If you use the Internet Information Server, the username for anonymous logon, e.g. |USR_NATWEB, is used. |USR_NATWEB must belong to the group USER, or the GUEST account must be enabled.
The new version of the EntireX Developer´s Kit supports the usage of two passwords and user IDs.
The first user ID is used to get access through EntireX Security and the second for Natural Security.
The HTTP Server Security is involved as a third security system.
Restrict the access of the NWW interface at your HTTP Server. For details, refer to your HTTP server documentation.
In the configuration file the NWW_USER_ID and
NWW_PASSWORD have to be specified.
A second User ID/Password (RPC_USER_ID,
RPC_PASSWORD) has to be set.
If the parameter USE_REMOTE_USER is activated, the
RPC_USER_ID will be set/overwritten. The RPC_PASSWORD
remains unchanged.
It is necessary to set up Natural Security with "AUTO=ON"
to pass security without password. If no
RPC_USER_ID/RPC_PASSWORD pair is set, the
NWW_USER_ID/NWW_PASSWORD will be used to ensure
compatibility with the existing implementation.
