/DISplay LOGON Keywords and Parameters

After you issue the ETA enhanced /SECURE command, use the /DISplay LOGON command to display information about logon capabilities for IMS systems.

See SECURE-Command for information about ETA enhancements to the /SECURE command.

You can use the following keywords and parameters with the /DISplay LOGON command:

ALLOWED

When used without the nodename parameter, the /DISplay LOGON ALLOWED command displays a list of all nodes that are allowed to log on to an IMS system.

The following figure shows sample output for the /DISplay LOGON ALLOWED command. Output similar to this sample is produced if each of the following conditions exist:

  • The ETA /SECURE DISABLE LOGON command prevents logons
  • The /SECURE ALLOW LOGON nodename command allows two nodes (in this case, L315A4 and L315A5) to log on

Figure 1. /DISplay LOGON ALLOWED Sample Output

L315A5    L315A4
*94084/133652*

The following parameter limits the display to specific node names:

nodename

The nodename parameter verifies that the /SECURE ALLOW LOGON command has been issued to allow one or more specific terminals to log on to the IMS system, even though the logon is globally disabled. When specifying multiple terminals, separate the node names with spaces. Generic parameters are supported, but /DISplay LOGON ALLOWED * is invalid.

The following figure shows sample output for the /DISplay LOGON ALLOWED nodename command. In this sample, the node name is L315A4.

NODE      LOGON  STATUS
L315A4    LOGON  IS ALLOWED BY L315A4
*94084/134023*

DISABLED

When used without the nodename parameter, the /DISplay LOGON DISABLED command displays a list of all nodes that are prevented from logging on to an IMS system.

The following figure shows sample output for the /DISplay LOGON DISABLED command. Output similar to this sample is produced if each of the following conditions exist:

  • the ETA /SECURE DISABLE LOGON command prevents logons
  • the /SECURE DISABLE LOGON nodename command prevents two nodes (in this case, L315A4 and L315A5) from logging on

Figure 3. /DISplay LOGON DISABLED Sample Output

L315A5    L315A4
*94084/133652*

The following parameter limits the display of nodes that are prevented from logging on to an IMS system:

nodename

The nodename parameter verifies that the /SECURE DISABLE LOGON command has been issued to prevent one or more specific terminals from logging on to the IMS system, even though logon is not globally disabled. When specifying multiple terminals, separate the node names with spaces. Generic parameters are supported, but /DISplay LOGON DISABLED * is invalid.

The following figure shows sample output for the /DISplay LOGON DISABLED nodename command. In this sample, the node name is L315A4.

Figure 4. /DISplay LOGON DISABLED nodename Sample Output

NODE      LOGON  STATUS
L315A4    LOGON  IS DISABLED BY L315A4
*94084/134023*

STATUS

The STATUS keyword determines whether logons have been prevented through the ETA /SECURE DISABLE LOGON command.

The following figure shows sample output for the /DISplay LOGON STATUS command if the ETA /SECURE DISABLE LOGON nodename command prevents specific terminals from logging on.

Figure 5. /DISplay LOGON STATUS Sample Output, Logons Disabled

LOGONS ARE SELECTIVELY DISABLED
*97091/182819*

The following figure6 shows sample output for the /DISplay LOGON STATUS command if the ETA /SECURE DISABLE LOGON command does not prevent logons.

Figure 6. /DISplay LOGON STATUS Sample Output, Logons Enabled

LOGONS ARE  ENABLED
*94084/113552*
