Definition of Nodes (2024)

Nodes are Entire System Server nuclei or Entire System Server/UNIX servers and refer to machines or CPUs on which requests to the operating system are executed. They are distinguished by numerical identifiers in the same way as database IDs distinguish between different Adabas databases.

If you are using Entire Operations in a multi-CPU environment, you must define node numbers for machines. Networks and jobs can thus be defined to run under Entire Operations control on different nodes.

Within Entire Operations, each UNIX and Windows server is assigned a node number. More than one operating system server node can reside in one physical machine. The machines identified by node IDs can run different target operating systems.

Entire Operations recognizes the operating system, thus allowing cross-operating-system job control. Communication paths between otherwise isolated nodes are provided by the Software AG products Entire Net-work and EntireX Broker, which allow a transparent connection of nodes, irrespective of how they are physically linked.

Trace Levels for UNIX and Windows Nodes

The Trace Level function only applies to UNIX and Windows nodes.

It is used to specify whether a trace is written to the log file and to determine the trace level (complexity) of the trace if written to the file. Valid input values:

Listing all Nodes

To list all nodes defined to Entire Operations

1. In the object workspace, select the Node metanode and choose List from the context menu, or press F8.

   A Node List window similar to the example below opens:

   

   The list is sorted by the Number column (default) in ascending order.

   You can click on the column by which you want to sort the list. A triangle in the column indicates the column by which a list is sorted (in the example above, the Number column).

   All columns are shown by default.

   The columns are explained in Columns: Operating System Server Table.

2. If you want to reorder columns or reduce the number of columns shown in the Node List window, choose Columns from the context menu:

   

3. Uncheck the column(s) you want to hide from the list and choose Hide.

   Or:
   Select the column you want to shift and choose Move Up or Move Down to move the selected column left or right in the list.

   You cannot move or hide the Number column.

4. When you are finished, choose OK to save and apply your changes.

   Or:
   Choose Cancel to undo all changes.

   Any column changes are persistent and retained for future sessions.

   If required, choose Reset to restore the default settings for the columns.

This section covers the following topics:

• Columns: Node List

Columns: Node List

The columns contained in the Node List window are explained in the following table.

Displaying, Modifying and Adding a Node Definition

This section covers the following topics:

• Displaying or Modifying a Node Definition

• Adding a Node Definition

• Fields: Node Definition - General

Displaying or Modifying a Node Definition

To display or modify a node definition

1. In the object workspace, select a Node instance.

2. If you want to display a node definition, choose Display from the context menu or press CTRL+D.

   Or:
   If you want to modify a node definition, choose Open from the context menu or press CTRL+O.

   A Display Node or Maintenance Node window (respectively) with an open General page similar to the example below opens:

   

3. Now you can change the definitions for the selected node.

   The fields in the upper section of the window and on the tabbed page General are used to specify general definitions for the node. They are explained in Fields: Node Definition - General.

   The fields on the other tabbed pages available are explained in the following section.

   Node - Specials

   The tabbed page Specials specifies user- and group-specific information for the node as shown in the example below:

   

   The fields available on the Specials page are described in

   • Special Definitions for a Node (Mainframe) and

   • Special Definitions for a Node (UNIX and Windows).

   Node - Broker

   If use Broker is specified as the access mode, the additional tab Broker is displayed which contains EntireX Broker details for UNIX and Windows nodes.

   

   The fields contain the current attributes of the EntireX Broker service definition for the node.

   The EntireX Broker service definition can only be modified in the SATSRV text object in the Natural SYSSATU system library on the server. If you change the service definition, choose Refresh to force a re-read of the service definition from SATSRV/SYSSATU into Entire Operations.

   Choose Delete if you want to delete all fields of an EntireX Broker service definition in Entire Operations at once.

   Note:
   This does not delete any entries in SATSRV/SYSSATU.

   Node - SAP Definitions

   If local node is specified as the access mode, the additional tab SAP Definitions is displayed which contains SAP settings for UNIX and Windows nodes.

   

   The fields on the tabbed page are explained in Fields: Node - SAP Definitions.

4. Choose OK.

   Your changes are saved.

Adding a Node Definition

To add a node definition

1. In the object workspace, select the Node metanode and choose New from the context menu, or press CTRL+N.

   A Create new Node window opens.

   The input fields and tabbed pages available in the window correspond to the fields and tabbed pages in the Maintenance Node window:

   • The fields in the upper section of the window and on the tabbed page General are explained in Fields: Node Definition - General.

   • The fields on the tabbed page Specials are explained in Fields: Node Definition - Specials (Mainframe) and Fields: Node Definition - Specials (UNIX and Windows).

   • The fields on the tabbed pages Broker and SAP Definitions (if available) are explained in Node - Broker and Node - SAP Definitions.

2. Enter the required values and choose OK to save the new node definition.

Fields: Node Definition - General

The fields in the upper section of a Create new Node or Maintenance Node window and on the tabbed page General are explained in the following table:

UNIX and Windows Node Definitions

UNIX and Windows nodes (i.e. on Entire System Server) must be defined in the following locations as well:

• SATSRV/SYSSATU (see the section Definitions for Entire System Server in the Installation documentation of System Automation Tools.)

• EntireX Broker parameters. You can omit these definitions for the Monitor node if this node is accessed in local mode.

• Entire System Server/UNIX or Windows initialization file npr.ini (see Customize the NPR Server in the section Completing the Installation in the Entire System Server documentation).

  Note:
  For each combination of UNIX or Windows node and user ID, at least one successful login (by LOGON NODE) must have been made, before this combination can be used within the Entire Operations Monitor. These LOGON NODE commands must be repeated after a password modification on a UNIX or Windows system.

Special Definitions for a Node (Mainframe)

The fields available on the tabbed page Specials of the Maintenance Node window depend on the access mode selected on the General page and the operating system of the server node.

Possible fields for a mainframe node are described in the following section.

Fields: Node Definition - Specials (Mainframe)

Special Definitions for a Node (UNIX and Windows)

The fields available on the tabbed page Specials of the Maintenance Node window depend on the access mode selected on the General page and the operating system of the server node.

Possible fields for a UNIX or Windows node are described in the following section.

Fields: Node Definition - Specials (UNIX and Windows)

SAP Definitions (UNIX and Windows)

Jobs of the type SAP require SAP-specific default values to set environment variables using jexa4S. All definitions are mandatory to run jobs of the type SAP.

Fields: Node - SAP Definitions

The fields on the tabbed page SAP Definitions of a Node definition window are explained in the following section:

Deleting a Node Definition

Before you delete a node, consider the impact on master or active objects using this node:

• When a node definition is deleted, this node is no longer available for new objects like network or job definitions.

• A deleted node is not invalidated in existing objects.

• A node status list can still show a deleted node as active.

• Various node access errors can occur if a deleted node is still referenced, for example, during network activation or job submission.

To delete a node definition

1. From the Node metanode in the object workspace, select the node you want to delete and choose Delete from the context menu, or press DELETE.

   A dialog opens where you have to confirm the deletion.
