增量备份无法使用section size参数

11g的rman备份有使用section size的参数，利用这个参数，你可以针对单个大文件的数据文件（如big file tablespace）采用并发的方式进行备份。可惜很遗憾，这个新特性的参数不能和增量备份一起使用。演示如下：

非增量备份的情况下：

RMAN>  run
2>  {
3>  allocate channel c1 type disk;
4>  allocate channel c2 type disk;
5>  allocate channel c3 type disk;
6>  allocate channel c4 type disk;
7>  allocate channel c5 type disk;
8>  allocate channel c6 type disk;
9>  allocate channel c7 type disk;
10>  allocate channel c8 type disk;
11>  backup section size 200M datafile 5 format 'c:\file5_%U_.bk';
12>  release channel c1;
13>  release channel c2;
14>  release channel c3;
15>  release channel c4;
16>  release channel c5;
17>  release channel c6;

19>  release channel c8;
20>  }

RMAN>

不管从log中分配的channel还是看备份出来的备份集，我们都看到没有使用多channel的并发。

该问题在RMAN-06183 When executing Level 1 Incremental backup and using Section Size [ID 1299598.1] 也说起了。只不过，我们演示的情况中甚至没有报错，还是一样不能在增量备份的时候，使用section size并发。

Cause

The functionality for performing an rman incremental leve1 1 or higher backup and using section size is not currently supported.

Solution

You cannot currently use these two rman features together.

This documentation bug has been filed because this limitation is not documented: 11813067.

This code bug has been filed because the error needs to be better indicate that this is not supported:  11813097.

This enhancement request has been filed because this functionality is requested in a future version of Oracle: 
11818263.

2013-06-23 update：

该问题已经在12c中修复，rman中的增量备份特性已经能和section size一起配合使用，详见惜纷飞的文章《ORACLE 12C RMAN 功能增强》
