# 巡检开始时间
start_time=$(date +"%Y-%m-%d %H:%M:%S")
echo "Start Time:" $start_time > $OUTPUT_FILE
echo "" >> $OUTPUT_FILE

# 检查数据库连接
echo "Database Connection:" >> $OUTPUT_FILE
sqlplus -S $DB_USER/$DB_PASSWORD@$DB_HOST:$DB_PORT/$DB_SID << EOF
SET PAGESIZE 0
SET FEEDBACK OFF
SELECT 'Connected to Oracle ' || version FROM dual;
EOF
