If it finds one,it attempts to rollback the transaction for that session (that was in progresswhen it was killed). The reason this cantake a long time is because PMON may have more than one transaction to rollbackat a time (if other sessions have been killed, or if processes have died...

ORACLE快速彻底Kill掉的会话 在ORACLE数据库当中,有时候会使用ALTER SYSTEM KILL SESSION 'sid,serial#'杀掉一个会话进程,但是使用这个SQL语句杀掉会话后,数据库并不会立即释放掉相关的资源,有时候你会发现锁定的资源很长时间也不会释放,即使会话状态为“KILLED”,依然会阻塞其它会话。 下面根据Eygel的"Oracle中Kill...

在Oracle中,我们通过profile,可以实现对session的部分资源的使用限制。例如: sessions peruser cpu per session maximum connect time maximum idle time maximum block reads per session maximum amountofprivate SGA. ... 比如我们要实现: 对一个学习用户study,当他的空闲时间超过2分钟后,系统自动断开连接. 那么我们...
SQL>create profile sessnum limit sessions_per_user 20; --最大连接数限制为20 3. 将PROFILE指定给用户: SQL>alter user test profile sessnum; 另外,SESSIONS_PER_USER不会像10g和11g那样限制12C中的并行从进程。 drop profile sessnum cascade; ...
后面应用方根据建议设置了中间件 Weblogic 连接池超时为 180s 最小连接数为 1 后,节点一 KILLED 也得到了释放,数据库的连接也下降到 400 左右了,算是一个正常范围值。 内存调整 前面说过内存管理为自动管理,这里需要将其调整为手动管理,由于是生产环境不能够随时重启则需要停机窗口,这里先将需要调整的内存参数以及...
