The only restriction when running an online backup in DB2 is that you cannot drop a table space while that table space is actively being backed up.

在 DB2 中运行在线备份的惟一约束是：当一个表空间正在被备份的时候，不能删除这个表空间。

youdao

Because this restriction is removed, even if the database is not created in UTF-8, a user can alter a table to add an XML column or create a new table with XML columns.

由于去掉了这个限制，即使数据库不是用utf - 8格式创建的，用户也可以更改一个表以添加xml列，或者创建一个包含xml列的新表。

youdao

In this table, "Y" shows that the restriction is indicated.

在这个表中，“Y”表示使用了限制。
