MFA creates dependent ASIDs using the reusable ASID attribute because they use cross-memory services. If this is not done, ASIDs may become depleted leading to the following system message:
IEA061E REPLACEMENT ASID SHORTAGE HAS BEEN DETECTED
Due to DB2, if it is invoked from a reusable ASID it will abend 0D3. Setting REUSE_ASID to 0 will avoid this.
If message IEA061E is received, all MFA ASIDs should be shutdown to mitigate the shortage.
| Value | Description |
|---|---|
| 0 | Dependent ASIDs are not reusable. |
| 1 | Dependent ASIDs are reusable. |
