namndchg (Change domain configuration (by using the system common definition))

The namndchg command changes the OpenTP1 domain configuration while OpenTP1 is active. Define the new domain configuration (a series of nodes) by the all_node operand in the system common definition. Then, execute this command. After the command terminates normally, the new domain configuration is applied.

Also, the namndchg command outputs the specification of the all_node operand to the standard output.

This command can be executed only when OpenTP1 is active.

(1) Output format when namndchg -l is specified

all_node information (aa...aa)
port number          node name
bbbbb                 cc....cc

aa...aa: all_node operand registration time (1 to 19 integers). Displayed in the format yyyy/mm/dd hh:mm:ss.

bbbbb: Port number (1 to 5 integers)

cc...cc: Node name (1 to 255 alphanumeric characters)

Message ID	Description	Output destination

KFCA00663-E	The command (namndchg) cannot continue because Y is specified for name_domain_file_use.	Standard error output

The namndchg command can increase the number of nodes and make the configuration larger.
After startup of OpenTP1, the number of nodes can be increased up to the value specified for the all_node_extend_number operand in the system common definition (or 64 if the operand is omitted).
To delete nodes from the all_node operand in the system common definition, stop all the SPPs running on those nodes and then execute the namndchg command. When nodes have been deleted while SPPs are active, an error may occur on transaction processing.
The specifications in the all_node_ex operand in the system common definition that take effect are those that you specify when OpenTP1 starts. Accordingly, you cannot use the namndchg command to change the all_node_ex operand while OpenTP1 is running.
However, if you use the all_node operand in the system common definition to perform the following changes, the applicable nodes are deleted from the all_node_ex operand after the namndchg command is executed:
If you move the nodes specified in the all_node_ex operand in the system common definition to the all_node operand in the system common definition

If you add the nodes specified in the all_node_ex operand in the system common definition to the all_node operand in the system common definition
The following table shows the changes you can make to the all_node operand and the status of the all_node and all_node_ex operands after the namndchg command is executed.

Table 13-5 Changes you can make to the all_node operand and the status of the all_node and all_node_ex operands after the namndchg command is executed

Type of operation for the all_node operand	Example of change you can make	Status after the command is executed
Type of operation for the all_node operand	Example of change you can make	all_node operand	all_node_ex operand
Addition	Adding a node that is not specified in the all_node_ex operand to the all_node operand	The applicable node is added.	No change
	Moving a node specified in the all_node_ex operand to the all_node operand	The applicable node is added.	The applicable node is deleted.
	Adding a node specified in the all_node_ex operand to the all_node operand	The applicable node is added.	The applicable node is deleted.
Deletion	Deleting a node specified in the all_node operand	The applicable node is deleted.	No change
Deletion	Moving a node specified in the all_node operand to the all_node_ex operand	The applicable node is deleted.	No change
