Registering a Daemon and Setting File Permissions

If you installed Entire System Server (NPR) on a UNIX system and did not use sudo, the installer was not able to register daemons and set file permissions for the affected products. Perform these tasks now by executing the script afterInstallAsRoot.sh as the root user. You can find this script in the bin directory of your main installation directory. It contains actions for all installed Software AG products.

If you do not want to register a daemon for Entire System Server (NPR) or set file permissions, proceed as follows:

• Remove the command to start the setup script in the afterInstallAsRoot.sh script before you execute it. The script to register the daemon is called install_daemon_npr. The script to set file permissions is called install_bin_npr. All these scripts are located in the <install-dir>/EntireSystemServer/INSTALL directory.

For the daemon, an uninstall script is available. Therefore, if you do not want to register the daemon, you can also proceed as follows:

• Install all daemons (either automatically with the installation when sudo is used, or manually by executing the afterInstallAsRoot.sh script when sudo is not used) and then uninstall the Entire System Server daemon using the uninstall_daemon_npr script in the <install-dir>/EntireSystemServer/INSTALL directory.

Setting the Environment Variables with sagenv.new

Before you start your product, it is recommended that you run (source) the sagenv.new script in the <install-dir>/bin directory. This sets the environment variables needed to run your product and other Software AG products.

Setting up Entire System Server Components

Entire System Server on UNIX is set up with the following steps

• Step 1: Customize EntireX Broker

• Step 2: Establish Environment Variables

• Step 3: Set Environment Variable ETB_TIMEOUT

• Step 4: Customize the NPR Server

• Step 5: Start Work with Entire System Server

Step 1: Customize EntireX Broker

The following definitions must be included in the EntireX Broker attribute file:

DEFAULTS=SERVICE
TRANSLATION=SAGTCHA
SERVER=<nodename>
CLASS=NPR
SERVICE=<npr_identifier>

where

<nodename>	is the identification of the node where the server is active.
<npr identifier>	is the identification of the service name provided for the NPR server.

Repeat these definitions for every NPR server specified in the npr.ini file. For instance, if an NPR server is available in the HP001 node with the service name nprdemo, the following definitions must be created:

DEFAULTS=SERVICE
TRANSLATION=SAGTCHA
SERVER=HP001
CLASS=NPR
SERVICE=nprdemo

For installing EntireX Broker, see the latest documentation.

Step 2: Establish Environment Variables

Some environment variables are set by the sagenv.new (nprenv) script if it is invoked during session startup:

• NPR_HOME points to the Entire System Server directory;

• points to the Entire Operations work directory. If this variable is already set, it will not be modified by this script.

• If Open Print Option (OPO) is installed, Entire System Server makes use of the environment variable OPO_HOME.

Depending on the platform, the following environment variables are modified by the sagenv.new (nprenv) script:

• All UNIX platforms

  PATH=$PATH:$NPR_HOME/bin

• HP-UX, AIX:

  SHLIB_PATH=$SHLIB_PATH:$NPR_HOME/lib

• Sinix

  LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$NPR_HOME/lib

Step 3: Set Environment Variable ETB_TIMEOUT

To enable an Entire System Server (NPR) service to stop while the TCP/IP connection to the Broker is down, the environment variable ETB_TIMEOUT is automatically set to 60 seconds by NPRETB and NPRMGR.This avoids a hang of the broker stub during a disconnected TCP/IP connection, and allows the stopping of npretb in such a situation. Note that ETB_TIMEOUT remains unchanged if it was set before the execution of npretb resp. nprmgr.

Step 4: Customize the NPR Server

The npr.ini file is used to define the behavior of the server processes. It is structured in one [DEFAULTS] section and one or more [<npr identifier>] sections.

You can define settings either in the [DEFAULTS] section or in an [<npr identifier>] section:

• Define Settings in a Section
• Settings in a [<npr identifier>] Section

Define Settings in a Section

The [DEFAULTS] section contains default values that apply to all servers. For a particular server such a default can be overwritten by providing an [<npr identifier>] section with an alternative setting.

Settings in a [<npr identifier>] Section

The [<npr identifier>] sections are optional, and can be created or modified later. They are used to define items specific to a certain server when these are different from default.

Any item defined in the [DEFAULTS] section can also be defined for each [<npr identifier>] section.

Any item defined in the [DEFAULTS] section can also be defined for each [<npr identifier>] section. If an item is not defined in this section, it is taken from the [DEFAULTS] section.

Step 5: Start Work with Entire System Server

This section covers the following topics:

• Starting a Server
• Stopping a Server

You can omit this step, if Entire System Server is to be used in "local mode" by Entire Operations or Entire Output Management. In this case, no separate NPR server is necessary.

You can omit this step if the application using Entire System Server is running on the same machine as the NPR server. In this case, you must setup the application using Entire System Server (for example: Entire Operations) in a way that it will access the NPR server in the so called "local mode".

For details, see the System Administrator's Documentation of the application that uses Entire System Server.

The npretb module is the Operating System Server for Entire Operations. It can receive remote requests from clients using the EntireX Broker mechanism. The server executes the system functions by calling the adequate function in the dynamic library nprlib.sl. The characteristics of the client/server communication established through the EntireX Broker mechanism are as follows:

• Connection-less oriented mode;

• Broker class always equal to NPR; User identifier always equal to NPR_ETBS;

• Service name always equal to <npr identifier>;

• Default internal timeout value equal to 30 seconds;

• Default internal replica value equal to "YES". This characteristic relative to replica servers is not implemented in the current version.

The npr.ini file defines the attributes related to an NPR server.

Starting a Server

To start a server

1. Use the NPRMGR utility:

   $ nprmgr
   NPRMGR> start service <service name>
   

2. You can check that the server has been successfully initiated with the NPRMGR utility:

   $ nprmgr
   NPRMGR> display service <service name>

Stopping a Server

To stop a server

1. Use the NPRMGR utility in this way:

   $ nprmgr
   NPRMGR> stop service <service name>

   Note:
   See the subsection The NPRMGR Utility for more information about these commands.

2. Invoke the startnpr script directly, followed by the service name:

   startnpr <service-name>
