看了下相关文档了:
Before moving a schema repository, complete these preliminary tasks:
1. Create an empty database in the new location using your vendor tool. You can create Microsoft Access databases with the Maintenance Tool. To create other supported databases, you must use the database vendor tools. For more information about configuring vendor databases, see the IBM Rational ClearQuest and ClearQuest MultiSite Installation and Upgrade Guide.
2. Instruct all users to log off from the databases. New users cannot access the databases while you are moving the schema repository, but users who are currently logged in when the process begins cannot be detected or logged off. Some supported databases provide a tool for logging users off the database. Determine whether your database vendor has such a tool.
3. Back up all Rational ClearQuest databases, even if you are moving only one schema repository or one user database. Backups prevent data loss due to unforeseen circumstances, such as network failure, that might occur during the move.
1. 对于schema迁移,一种是schema的迁移在maintenance tool里move即可,另一种是通过vendor database tools来迁移然后在update下maintenance tool的连接;
2. 对于user databases的迁移也是这两种方式;
3. 有几个问题:
3.1 schema数据库只是存储schema,而在CQ所有记录(包括CQ的查询等)的数据库都存储在user databases,这样认为是不是正确的?
3.2 vendor database tools这里的vendor啥意思呢?
3.3 是否真的有必要Backup all Rational ClearQuest databases,比如我只是想迁移一个userdatabase而已,这里的备份好像不能从disigner进行备份,只能从数据库进行备份?
