Dear Wiki user, You have subscribed to a wiki page or wiki category on "Ws Wiki" for change notification.
The following page has been changed by KevinWilliams: http://wiki.apache.org/ws/WorkingWithOptimisticConcurrencyControl ------------------------------------------------------------------------------ </Config> }}} + This line in the config file ''<Column columnName="OCC" collision="true" managed="true"/>'' designates the column named "OCC" as the version column and also sets "managed" to true. The "managed" attribuete has to do with how the version column is changed. In order for OCC to work, somebody has to change the value of the version column each time the row is modified. A new value in the version column is what tells the DAS that some agent has modified the row. If a version column is "managed" then the DAS is responsible for incrementing the value of the column each time some column in the row is changed. The other option is "managed= false" and in this case, the DAS will assume some other agent is responsible for updating the version column. This other agent is likely to be the client application itself or the database via a trigger or some other mechanism. + --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
