Method of automatic startup and exit upon power on

(1) Auto startup and auto stop of each daemon on HULFT

You can use a script file to automatically start each HULFT daemon when the operating system is rebooted.

Similarly, you can use a script file to automatically stop each HULFT daemon while the operating system is stopped.

The settings for auto startup and auto stop differ depending on the operating system in use. Refer to the relevant guide book for details.

The following describes how to set up auto startup and auto stop for RedHat Enterprise Linux 7 as an example.

The following tasks must be carried out by a user with superuser (root) permissions.

1. Create a script file.

Create a script file as below, and save it as "/usr/local/bin/hulft".

Change the permissions of the script file to 755.

#!/bin/bash 

HULEXEP=/HULFT execution module storage directory 
HULPATH=/HULFT environment settings file storage directory 
PATH=/HULFT execution module storage directory:$PATH 
export HULEXEP 
export HULPATH 
export PATH 

if [ "$1" = "start" ]; then 
    if [ ! -f /var/lock/subsys/hulft ]; then 
        hulsndd 
        hulrcvd 
        hulobsd 
        touch /var/lock/subsys/hulft 
    fi 
elif [ "$1" = "stop" ]; then 
    if [ -f /var/lock/subsys/hulft ]; then 
        utlkillsnd 
        utlkillrcv 
        utlkillobs 
        rm -f /var/lock/subsys/hulft 
    fi 
fi 
 
exit 0

2. Check the run level.

# systemctl get-default 
graphical.target

3. Create the service file for the system management daemon.

Create the service file as shown below. In this case, in the final line of the file, specify the run level that you checked in 2. .

Save the created service file as "/etc/systemd/system/hulft.service" and change the permissions to 755.

[Unit] 
Description=hulft auto restart 
After=network.target network-online.target 

[Service] 
ExecStart=/usr/local/bin/hulft start 
ExecStop=/usr/local/bin/hulft stop 
Type=forking 

[Install] 
WantedBy=Run level

4. Enable the auto startup of each daemon on HULFT.

Run the following commands to enable the auto startup of each daemon on HULFT.

# systemctl daemon-reload 
# systemctl enable hulft

(2) Auto startup of the Receive Ready Notification command (issuance of the Resend Request command)

Add the following line to the script file that you created in 1. of (1) Auto startup and auto stop of each daemon on HULFT when the Receive Ready Notification command of HULFT is automatically started at the startup of the operating system.

utlrecv -a

[Example]

#!/bin/bash 

HULEXEP=/HULFT execution module storage directory 
: 
Omitted 
: 
        hulobsd 
        utlrecv -a                   <- Add this line 
        touch /var/lock/subsys/hulft 
: 
Omitted 
:

Refer to Operation Manual for details about the Receive Ready Notification command.

Note

When there are a number of host names being registered, it takes time to end the command.
