The
SAS/SHARE lock manager enables multiple clients
to share the same SAS file at the same time. The server's ability
to manage multi-client access of selected data objects is contingent
on a complex set of locking rules that are affected by many factors.
These locking rules must be considered in relation to each programming
product (SAS and other products) that you use to write applications
that enable accessing data through the
SAS/SHARE server.
