Example: specifying concurrent copy job AUX deltas

Use the following command to modify the concurrent copy AUX delta to determine the point at which SDM will reject requests to start new concurrent copy tasks:
```
F ANTMAIN,P .CMTUN+3A X'FFFF' X'nnnn'
```
where nnnn is the new AUX delta value, in hexadecimal notation.

SDM subtracts this value from the lower MVS AUX storage limit percentage. The result is then compared to the percentage of AUX storage currently in use by the system. The default value is X'FFFF', indicating that SDM will not perform this check.
Use the following command to modify the concurrent copy AUX delta to determine the point at which SDM will terminate existing concurrent copy tasks:
```
F ANTMAIN,P .CMTUN+3C X'0000' X'nnnn'
```
where nnnn is the new AUX delta value, in hexadecimal notation.

SDM subtracts this value from the upper MVS AUX storage limit percentage. The result is then compared to the percentage of AUX storage currently in use by the system. The default value is 0, indicating that SDM will terminate concurrent copy sessions when the upper limit is reached. A value of X'FFFF' indicates that SDM will not perform this check.
