After you enter the activate command for a database set, users at the original database cannot access it without a MultiSite license (in addition to a Rational® ClearQuest® license).
The mkreplica –export command locks the database after you start to export the replica. All users must log off before the procedure begins and log on after it finishes. Data is lost if sessions are left open during the replication process.
Replica-creation packets can be four times as large as the respective databases. Verify that the working directory you use has enough free space. You must have write permission for the working directory, and the directory name must not exist.
