New ctFeatKEEP_XFREED Lock Mode to Mark Entires in User Lock Table for Unlock Requests During a Transaction

This highly specialized lock mode is a great example of the precision engineering FairCom provides for ultimate data management and flexibility.

ctFeatKEEP_XFREED enables support for ctMARK_XFREED on transaction Begins and ctKEEP_XFREED on transaction Ends. ctMARK_XFREED causes unlock requests during a transaction to add a special attribute bit to the user lock table entry which indicates an explicit unlock request has been made. During a transaction End, ctKEEP_XFREED queries use this attribute bit to determine whether or not the lock should be released.

Note: ctFeatKEEP_XFREED is only available when TRANPROC is defined.

Default

ctFeatKEEP_XFREED is enabled by default in v10.5.0 and later.
