IBM SC34-4499-03 manual Versioning drivers

Versioning drivers

TeamConnection creates new versions of drivers whenever you do the following:

vCreate a driver

When you create a new driver, TeamConnection makes two versions of it: myDriver:1, for example and myDriver:2.

vAdd a work area (driver member) to a driver

If you add myWorkArea:1 to myDriver:2, for example, TeamConnection creates a new version of myDriver called myDriver:3.

vFreeze a driver

Freezing a driver is like taking a snapshot of the driver. It preserves the parts as they are when the driver is frozen. If you freeze myDriver:3, for example, TeamConnection creates a new version called myDriver:4.

vRefresh a driver

Refreshing a driver updates the driver with all changes that have been made in all of its driver members. Refreshing a driver actually creates two new versions of the driver, as follows:

1.Freezes the driver (so that TeamConnection can have a point to roll back to if an error occurs during the refresh operation).

2.Updates the driver with any changes from the driver members

3.Freezes the driver again, thus preserving a copy of the updated driver.

If the current version of myDriver is myDriver:2, for example, and the parts in its driver members have been changed, then TeamConnection does the following when it refreshes the driver:

1.Freezes myDriver, creating myDriver:3.

2.Updates myDriver with changes from its driver members.

3.Freezes myDriver again, creating myDriver:4.

The result of refreshing myDriver (version myDriver:2) is two new versions: myDriver:3, containing a snapshot of the driver before the refresh, and myDriver:4, containing a snapshot of the driver after the refresh.

TeamConnection deletes versions of drivers whenever you remove driver members or commit a driver to a release.

vIf you have a driver version myDriver:4 with driver members myWorkArea, yourWorkArea, and ourWorkArea, and you remove myWorkArea, then TeamConnection deletes driver versions myDriver:2, myDriver:3, and myDriver:4 and creates a new driver version called myDriver:5 containing members yourWorkArea and ourWorkArea. As a result, the family contains two versions of the driver, myDriver:1 and myDriver:5.

vWhen you commit a driver to a release, all intermediate versions of the driver (resulting from driver member add, driver freeze, driver refresh, or driver member remove operations) are deleted.
