# Definition of Nodes

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 GmbH products Entire Net-work and EntireX Broker, which allow a transparent connection of nodes, irrespective of how they are physically linked.

For an example scenario, see the section Entire Operations in Client/Server Environments in the Installation and Setup documentation.

- Fields: Node Definition

### Fields: Node Definition

The fields in the Node Definition or Node Modification window are explained in the following table:

Field | Description
--- | ---
Node Number | Node number. Valid range: 1 to 99900.
Short Name | Mnemonic short name for the node. The mnemonic short name can be used instead of the node number in various locations. This can be set in the Representation options of the user profile.
Node Name | Unique, user-defined node name. For nodes with access mode `N`: Enter a short description to help the user select an appropriate node for a network or job run. For nodes with access mode `B`: Enter the name of a UNIX or Windows node (server) as it appears in System Automation Tools and EntireX Broker definitions in the SATSRV text object contained in the Natural SYSSATU library (see also the example of a node definition in the Installation and Setup documentation). This field is case-sensitive.
Access Mode | Possible values:
`N` | Use Entire Net-Work for mainframe nodes.
`B` | Use EntireX Broker.
`L` | Use the local node (invoked directly on the machine where Entire Operations is running; for Entire Operations on UNIX and Windows only).
Time Difference | Difference between local time and GMT in hours if the node is in a different time zone. Input format: `xn`, where: `x` is a plus or minus sign (`+` or `-`), and `n` is any number from 0 to 12.
Password Mode | This setting is evaluated for nodes on z/OS only. Conversion mode to be used for password entries. Possible values:
`U` | Passwords are converted to upper case (default for mainframe nodes).
`M` | Passwords in lower or mixed case are not converted to upper case (default for UNIX and Windows nodes).
The password mode currently set is indicated in the Node Logon window (see the section Logon Function in the User's Guide).
Wait after Error | Time in minutes to wait until the next node access after a temporary error. Default: 5 minutes.
Node Security User Type | Node security user type can be set individually for each node. If this field is blank, the global default applies to this node: see the Node Security User Type field described in Monitor Defaults for possible values of this field.
Valid | Allow or disallow use of the node. Possible values:
`Y` | Allow use.
`N` | Disallow use.

## 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.

## Viewing Node Information

The Node Information window displays general information on the node. In addition to the Node Modification window, it also provides product-specific information.

  The fields (read-only) contain the current attributes of the EntireX Broker service definition specified for the node.

  The EntireX Broker service definition for the node can only be modified in the SATSRV text object in the Natural SYSSATU system library on the server. If you change the service definition, use PF6 (see below) for an update.

  The window provides the following special PF keys:

  PF Key | Name | Function
  --- | --- | ---
  PF6 | Refresh | With this function you can force a re-read of the service definition from SATSRV/SYSSATU into Entire Operations.
  PF9 | Delete | With this function you can delete all fields of an EntireX Broker service definition in Entire Operations at once. Note This does not delete any entries in SATSRV/SYSSATU.

## 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. On the Operating System Server (Node) Table screen, enter the line command `D` next to the required node and press ENTER.

   A confirmation window opens.

2. Enter the node number and press ENTER to confirm the deletion and close the window.
