Adding Clusterware entries to inittab
ohasd failed to start

報錯原因：
因為RHEL 7使用systemd而不是initd執行程式和重啟程式，而root.sh透過傳統的initd執行ohasd程式。

解決：
在RHEL 7中ohasd需要被設定為一個服務，在執行指令碼root.sh之前。

步驟：
1. 使用root使用者

[root@Oraclelinux ~]# cd /etc/systemd/system/
[root@Oraclelinux system]# touch ohasd.service
--此處oracle MOS 文件描述錯誤，應修改為 touch ohas.service

2. ohas.service 檔案中新增如下引數

[Unit]
Description=Oracle High Availability Services
After=syslog.target

[Service]
ExecStart=/etc/init.d/init.ohasd run >/dev/null 2>&1 Type=simple
Restart=always

[Install]
WantedBy=multi-user.target

3. 用root使用者執行以下命令:

[root@Oraclelinux ~]# systemctl daemon-reload
[root@Oraclelinux ~]# systemctl enable ohas.service
[root@Oraclelinux ~]# systemctl start ohas.service

4. 檢視執行狀態
[root@b2i-order-db1 init.d]# systemctl status ohas.service
ohas.service - Oracle High Availability Services
Loaded: loaded (/usr/lib/systemd/system/ohas.service; enabled)
Active: failed (Result: start-limit) sincesince Tue 2017-01-03 18:00:27 CST;2s ago

Process: 5734 ExecStart=/etc/init.d/init.ohasd run >/dev/null 2>&1 Type=simple (code=exited, status=203/EXEC)
Main PID: 5734 (code=exited, status=203/EXEC)
狀態為failed ，此時狀態為失敗，原因是現在還沒有/etc/init.d/init.ohasd檔案。

5、執行root.sh 指令碼後狀態
● ohas.service - Oracle High Availability Services
