可以使用以下命令查看Oracle是否启动:
1. 检查Oracle进程是否存在:
```
ps -ef | grep ora_
```
如果看到类似以下输出,则表示Oracle已经启动:
```
oracle 1751 1 0 2018 ? 00:00:00 ora_pmon_orcl
oracle 1753 1 0 2018 ? 00:00:02 ora_dbw0_orcl
oracle 1755 1 0 2018 ? 00:00:00 ora_lgwr_orcl
oracle 1757 1 0 2018 ? 00:00:00 ora_ckpt_orcl
oracle 1759 1 0 2018 ? 00:00:00 ora_smon_orcl
oracle 1761 1 0 2018 ? 00:00:03 ora_reco_orcl
oracle 1763 1 0 2018 ? 00:00:00 ora_mmon_orcl
```
2. 检查Oracle监听器是否启动:
```
lsnrctl status
```
如果看到类似以下输出,则表示Oracle监听器已经启动:
```
