ORACLE BASICFILE LOB字段空间回收SHRINK SPACE的疑惑
2022-07-28 01:50:00 【张sir】
再针对lob字段空间回收的时候发现
针对:BASICFILE lob
如果是单独对lob字段进行SHRINK SPACE,不用需要开启表的行移动(enable row movement),也可以回收空间。是不是针对LOB字段进行SHRINK SPACE不是必须开启表的行移动?,请大佬解惑下,是因为LOB字段的空间是单独管理的原因吗?
其他答案1:
可以参考这篇文章:
https://oracle-base.com/articles/misc/alter-table-shrink-space-online
1、根据里面的实验的情况,对于lob字段在shrink的时候,确实没有开启row movement
2、在一个表里,如果有普通字段和lob字段,lob字段需要单独进行shrink
3、securefile LOB没拌饭shrink。
