临时对策:重新执行Rman L0 备份
2014-06-12 重新执行L0备份后，在执行L1 增量备份成功。
2014-06-13 Oracle 官方给予的解释：
Based on our findings, we are suspecting Bug 17025461 : EXADATA: ORA-600 [KRBBSTHROTTLE_ ZERO_TOTAL_SIZE] ON RMAN INCREMENTAL
LEVEL 1 for this issue.
Possible Workaround:
1) Don't set auto-extend on for datafiles. Create larger datafiles to account for space expansion.
If that is not possible, reduce the possiblity of auto-extending datafiles (by specifying extend size larger value).
翻译：不要设置自动扩展上的数据文件。创建更大的数据文件要占空间扩展。如果这是不可能的减少的可能性的自动扩展数据文件 （通过指定扩展规模较大的值）
2) Use higher value of MAXPIECESIZE to prevent possibility of hitting
this bug.
翻译：配置Rman使用更高价值的 MAXPIECESIZE，防止击中这个 bug 的可能性
3)
Also setting _disable_cell_optimized_backups=TRUE, may help in avoiding the bug.
翻译：也可设置
_disable_cell_optimized_backups = TRUE，可能有助于避免 bug
The patch is available for 11.2.0.3BP17 and the issue is fixed in version 12.2.
