Firebird 2.5报告“不是有效的数据库".虽然是 [英] Firebird 2.5 reports "is not a valid database" although it is

问题描述

我有两台同时运行Firebird的计算机(分别称为A和B)和两个数据库文件(分别称为a.fdb和b.fdb)，它们都已复制到两台计算机上.在B上我收到消息

I've got two computers both running Firebird (let's called them A and B) and two database files (let's call them a.fdb and b.fdb), both copied to both computers. On B I get the message

b.fdb不是有效的数据库 其他文件都起作用，两个文件都起作用.

b.fdb is not a valid database The other files work, on A both files work.

如果B是较旧的版本，但是它是较新的版本(它是FB 2.1，并且由于这个问题，我安装了FB 2.5)，这很容易解释.文件a.fdb和b.fdb分别具有ODS 11.1和10.1.看来FB的新版本不再支持ODS 10.1，我不敢相信.但我没有其他解释，可以吗?

This would be easy to explain, if B was an older version, but it's a newer one (it was FB 2.1, and because of this problem I installed FB 2.5). The files a.fdb and b.fdb have ODS 11.1 and 10.1, respectively. It looks like new versions of FB wouldn't support ODS 10.1 anymore, which I can't believe. But I see no other explanation, can you?
