Connecting to a Lock Structure

This topic describes the IXLCONN parameters that you code to connect to a lock structure. To help you code the IXLCONN macro, use the general IXLCONN guidance information in “Connecting to a Coupling Facility Structure” together with the information provided here.

The first application that connects to a lock structure allocates the structure and defines its characteristics. Subsequent connectors to the structure use the structure as it has been allocated by the first connector. The following IXLCONN parameters define the attributes of the lock structure:

RECORD: Specifies whether the lock structure is to include record data.
RNAMELEN: Specifies whether resource names are a fixed or a variable length for the lock structure.
LOCKENTRIES: Specifies the number of lock entries in the lock structure.
NUMUSERS|MAXCONN: Specifies the maximum number of users allowed to connect to the lock structure.
MONITORSTORAGE: Specifies whether internal storage for lock structures is to be monitored.
CONTEXIT: Specifies the address of your contention exit.
NOTIFYEXIT: Specifies the address of your notify exit.
