(LOAD_BALANCE = NO) ) (CONNECT_DATA = (SERVICE_NAME = TESTRAC) ) ) 根据文章开头给出的连接文章可以确定,当REMOTE_LISTENER设置为空时,服务名指定一个地址,连接这个服务名是不会连接到两个实例上的,这里测试一下当存在两个地址的情况,先将LOAD_BALANCE设置为NO: SQL> HOST SQLPLUS YANGTK/YANGTK@TEST...
1. 负载均衡的情景包括 tick balance、nohz idle balance 和 new idle balance，最终都会汇聚到 load_balance 函数来完成具体的负载均衡⼯作。⼆、load_balance 相关数据结构 1. struct lb_env 在负载均衡的时候，通过 lb_env 结构来表⽰本次负载均衡的上下⽂：//fair.c struct lb_env { //要进⾏...

idle balance:指cpu已经进入idle状态,在tick时做的load balance。如果是NO HZ的话,会尝试做nohz idle balance。 newly idle balance:CPU上没有可运行的task,准备进入idle 的状态。在这种情况下,scheduler会尝试从别的CPU上pull一些进程过来运行。 active load balance:在尝试load balance几次失败后,根据条件判断进行...

在more_balance中,会判断busiest rq是否在做active balance,如果是的话,就不进行迁移,并goto到no_move 在no_move中,如果几轮尝试后,仍然没有迁移task,就可能需要判断是否需要active balance need_active_balance会判断是否需要进行active balance和是否满足条件 在经过一些过滤条件后,开启stop class工作队列,进行active...

oracle@SZDB:~> grep ora10g2 no_load_bal_new.log |wc -l 100 由于实例ora10g1已经关闭,因此所有的连接请求都被分配到ora10g2。 四、总结 1、客户端的负载均衡配置较为简单,仅仅是在客户端的tnsnames.ora添加 LOAD_BALANCE = yes |on 2、其连接分配原则是根据tnsnames.ora中连接标识符下的ADDRESS列表随机...
