CQS structure allocation
A structure is allocated the first time a CQS connects to it and remains allocated until you explicitly delete it using the z/OS® SETXCF command.
When a CQS connects to a structure, the structure might be empty; that is, it might contain no data, might contain only CQS control information, or it might contain client data. The structure can be empty if:
- This is the first time a CQS is accessing the structure.
- You scratched the structure to perform a structure cold start.
- A structure failure occurred and the structure must be recovered.
