[可能发生的现象]
由于网络断线造成网络故障，恢复前，信息交换受到阻碍，直到重新开始传输信息为止，需要一定时间。
以下是发生这种情况时，警报日志的输出例。
– 源数据库 : CAPTURE01（获得进程）
-目标数据库 : APPLY011（应用进程）

执行重启应用进程（终止、开始）后，到检测到应用进程无效化，需要一定时间。
通过获得进程检测到错误后，马上重启获得进程 (*3)。
[对象版本]
发生问题的版本 ：Oracle Database 11g Release 2(11.2.0)
Oracle Database 11g Release 2(11.1.0)
修复了问题的版本 ：无
预定修复问题的版本：未定
已修复问题的PSR ：无
预计修复问题的PSR ：未定
[目标平台]
所有平台
[可能发生的条件]
满足以下条件的话就可能发生。
– 获得与应用的复合 (CCA)有效
– 发生网络故障后，已修复的状态
[原因]
开发部还在研究。
根据研究情况，依次会反映在 KROWN 中
[发生故障时的对策]
1.直到信息交换自动重启为止一直待机。
- 请手动重启获得进程与应用进程
终止获得进程 ->终止应用进程 ->开始应用进程-> 开始获得进程
