请求帮助，oracle 数据库做rman 备份时，备份的数据不完整。

OS:   5300-09
oracle版本: Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit
架构： oracle RAC
问题：oracle 数据库做rman 在线备份时，备份前面几个数据文件后，自动断开，没完整备份完数据。
rman 脚本：
connect target /
run {
ALLOCATE CHANNEL t1 DEVICE TYPE DISK;
ALLOCATE CHANNEL t2 DEVICE TYPE DISK;
backup
incremental level 0
TAG 'HOT_DB_LEVEL0'
FILESPERSET 4
FORMAT '/data/olddump/DB_%d_s%s_p%p_t%t'
DATABASE;
RELEASE CHANNEL t1;
RELEASE CHANNEL t2;
ALLOCATE CHANNEL c1 DEVICE TYPE DISK CONNECT 'sys/oracletg@DB01';
ALLOCATE CHANNEL c2 DEVICE TYPE DISK CONNECT 'sys/oracletg@DB02';
sql 'alter system archive log current';
BACKUP
filesperset 20
FORMAT '/data/olddump/archal_%s_%p_%t'
ARCHIVELOG ALL;
RELEASE CHANNEL c1;
RELEASE CHANNEL c2;
ALLOCATE CHANNEL ch00 TYPE DISK;
BACKUP
FORMAT '/data/olddump/cn_%d_s%s_t%t_p%p'
CURRENT CONTROLFILE;
RELEASE CHANNEL ch00;
}
rman备份产生日志:
connected to target database: OA (DBID=3112272670)

using target database control file instead of recovery catalog
allocated channel: t1

数据库和数据文件共178个，只备了8个就停止了退出了。

一种可能是 报错的日志没有正常输出
一种是你的数据库的状态存疑

我查一下数据库状态都是正常的
SQL> select  OPEN_MODE from v$database;

OPEN_MODE
----------
READ WRITE

SQL> select status from v$instance;

STATUS
------------
OPEN

光看一个 read write + open可不代表什么 正常

请教一下刘老师，怎样去判断数据库的运行是否正常？

Maclean Liu(刘相兵

你重新备份 一下 脚本里加上debug on;
生成的log 上传

刘老师，我前几天出差了，今天才重新做调度，上传日志，请帮忙分析一下，谢谢。
