A persistent structure can be deleted only if there are no active or failed-persistent connections to the structure, no failed-persistent connections pending reconciliation into the CFRM active policy, and no structure dump associated with the structure. Deallocation of the structure occurs as follows:

• On systems with OW33615 installed or which are at OS/390® Release 9 or higher, when an attempt is made to connect to an inaccessible structure, and there are no active connectors to the structure, and there is no connectivity to the coupling facility containing the inaccessible structure by any system in the sysplex, the system will force the structure and its failed-persistent connectors. This allows the system to allocate a new instance of the structure so that the connector can successfully connect to it.
• On systems that do not have OW33615 installed or which are below OS/390 Release 9, any attempt to connect to an inaccessible structure will fail until connectivity has been reestablished, or the structure and its failed-persistent connectors have been forced.

  In either case (with or without OW33615 or whether at OS/390 Release 9 or not), deallocation of the structure remains pending until connectivity to the coupling facility is reestablished.

• If there is a structure dump associated with the structure, deallocation of the structure remains pending until the structure dump is deleted. This normally occurs upon completion of the SVC dump that created the structure dump, although you can also delete the structure dump using the IXLFORCE service.
