Exceptions occur when you monitor the message queue data set usage

Three exceptions warn you when the message queue data set utilization exceeds a threshold: ALMD, ASMD, and AQB, which represent the long, short, and QBLK data sets.

1. Review how these exceptions are set up in the product.
2. Use the XACB LIST= command in the Classic interface for your profile and adjust the thresholds as necessary.
