When using IXLCONN to connect to a structure, you specify structure attributes that describe the structure that you need. Whether the attributes you specify are used by the system depends not only on your IXLCONN parameters, but also on resource availability in the coupling facility, what the installation has defined in its CFRM policy, and whether your IXLCONN request causes the allocation of the structure.

The structure to which you receive connectivity might or might not meet all your requirements. The system returns the actual attributes of the structure to you in the connect answer area, mapped by the macro IXLYCONA. It is your responsibility to verify that the attributes of the structure, as indicated in the answer area, are acceptable. If you decide not to accept one or more of the attributes, you can disconnect from the structure or attempt to rebuild it with different attributes.

The attributes discussed here are generic for each structure type. There are additional attributes that are specific to the type of structure. For a description of the information required on IXLCONN for each structure type, see Connecting to a Coupling Facility Structure.
