Overview

This guide explains the automatic TAC execution feature upon Linux OS reboot. 

Method

1. Create tibero_auto_boot Script

vi /usr/bin/tibero_auto_boot
#!/bin/bash
export TB_HOME=/tac/tibero7
export CM_HOME=/tac/tibero7
export CM_SID=cm1
export LD_LIBRARY_PATH=$TB_HOME/lib:$TB_HOME/client/lib:$TB_HOME/../lib_dummy:/usr/openv/lib/
export PATH=$PATH:$TB_HOME/bin:$TB_HOME/client/bin
sh /tac/boot_script/boot_all.sh


vi /tac/boot_script/boot_all.sh
sleep 30
tbcm -b
sleep 10
cmrctl start as --name tas1
sleep 10
cmrctl start db --name tac1


** /tac/boot_script/boot_all.sh contains the boot commands as shown above
(or you can write them directly in tibero_auto_boot)

** If sleep is omitted or set too short, CM or services may not boot properly,
so 30 seconds sleep before tbcm -b and 10 seconds sleep before each instance boot were added.

** Grant execution permission
chmod 744 /usr/bin/tibero_auto_boot
chmod 744 /tac/boot_script/boot_all.sh

2. Create tibero_auto_boot Service

Create a tibero_auto_boot service in the OS systemd. 

vi /etc/systemd/system/tibero_auto_boot.service
[Unit]
Description=Tibero Auto boot systemd service.
[Service]
Type=simple
User=root
ExecStart=/bin/bash /usr/bin/tibero_auto_boot
RemainAfterExit=true
[Install]
WantedBy=multi-user.target

3. Enable tibero_auto_boot.service

systemctl daemon-reload
systemctl enable tibero_auto_boot.service

** How to start and check status of tibero_auto_boot.service
systemctl start tibero_auto_boot.service
systemctl status tibero_auto_boot.service
