以前备份一直很正常昨天调度失败，
客户端查看rman生成的日志发现下列错误
RMAN-03009: failure of backup command on t1 channel at 09/17/2009 06:52:17
ORA-19502: write error on file "s1kpep14_1_1", blockno 1 (blocksize=512)

上服务器ISC上查看发现如下日志：
2009-9-16 10:51:53 ANE4994S TDP Oracle AIX ANU0599 TDP for Oracle: (712952): =>(dmsdb_oracle_client) ANU2602E The object /dmsdb_ora//rmkpcin1_1_1 was not found on the TSM Server (会话: 51267)
查看TSM消息文档，三个错误代码都没有什么可用信息
ANE4994S ANU2602E ANS1235E
只能 判断问题基本上是在服务器端。
GoogleANE4994S ANU2602E看完所有帖子，
发现大多是由于stg空间不足，
有些是TSM BUG或带库微码问题
晕，可我的问题全部都不是，
最后想想TSM在windows平台，重启带库和服务器，一切OK！
问题虽然解决了，郁闷中,,,,,,,,,,,
