Restrictions

The requestor can delete a persistent structure only if there are no active connections to the structure, there are no failed-persistent connections pending reconciliation into the CFRM active policy, and there is no structure dump associated with the structure.
A structure cannot be deleted while structure rebuild is in progress for the structure, because a structure for which rebuild is in progress must have at least one active connector.

A structure in the duplexing rebuild process can be deleted only if there are no active or failed-persistent connections, the structure is in the Duplex Established phase, and a switch to the new structure is not in progress.
The requestor can delete a failed-persistent connection. The failed-persistent connection will be deleted from the old structure, the new structure, or both instances of the structure. However, an active connection cannot be deleted, nor can a failed-persistent connection be deleted while structure rebuild is in progress for the structure.
A connection to a structure in the duplexing rebuild process can be deleted only when the connection is failed-persistent and the structure is in the Duplex Established phase with a switch to the new structure not in progress.
The requestor can delete only a single structure, structure dump, or structure dump serialization with one invocation of the IXLFORCE macro. However, the requestor can delete multiple failed-persistent connections to a structure with one invocation of the IXLFORCE macro.
A program can use the IXCQUERY macro to determine the set of objects that are candidates for deletion. In the case of forcing all failed-persistent connections to a structure, IXCQUERY can be used to determine the set of connections that either will be or were forced.
