oracle备份报错。

kindy

oracle数据库备份报错。 server: windows平台，  client:  IBM p650。 备份软件: veritas nbu 5.0   数据库： oracle 8.16
1。 nbu系统报错代码为25。
2。 当前的备份策略为增量备份，schdule的设置为按月设置，但是只有25号以后的几个增量出这种问题，全备和其他没出国这种问题，开始的时候以为是二十几号的计费周期的缘故，后移计费周期到每月一号，但是还是出这问题。
3。 备份oracle的增量，前一两个job可以备份， 后来出错。 rman 输入日志如下：
       RMAN-08008: channel ch00: starting incremental level 1 datafile backupset

4。 检查ORA-27028的报错，有如下解释：
ORA-27028 skgfqcre: sbtbackup returned error
Cause: SBTBACKUP returned an error. This happens when creating a backup file during a backup operation.
Action: This error is returned from the media management software which is linked with Oracle. There should be additional messages which explain the
cause of the error. This error usually requires contacting the media management vendor.
ORA-19624:operation failed, retry possibleCause:A backup, restore or image copy operation failed with an I/O error. If the source of the I/O error can be corrected, then the operation may be retried.Action:This message is used by Recovery Manager to decide whether or not to retry the operation.
5。 请现场工程师发bptm的日志。 并检查server和client的时间差。
