SCAN_IP是否负载均衡问题的解答

下文给大家带来SCAN_IP是否负载均衡问题的解答，希望能够给大家在实际运用中带来一定的帮助，负载均衡涉及的东西比较多，理论也不多，网上有很多书籍，今天我们就用创新互联在行业内累计的经验来做一个解答。

最近遇到一个测试项目，对SCAN_IP是否负载均衡有一个疑问？理论上说是可以负载均衡，自己做了一个测试验证一下。

事实证明，并不是轮训机制的负载均衡。

一个小小的脚本如下：

$less load_balance_scan.sh   

#!/bin/bash  

for i in {1..100}  

do  

echo $i

sqlplus -S system/oracle@orcl <

select instance_name from v\$instance;

select count(*) from t1;

EOF

sleep 1  

done  

exit 0 

$sh load_balance_scan.sh
