DYNALLOC specifies that DFSMSdss is to use dynamic allocation, instead of enqueue, to serialize the use of data sets. This allows cross-system serialization in a JES3/MVS environment. The following conditions apply to DYNALLOC: refids="b370_13">

• The serialization is of value only when the dynamic allocation/JES3 interface is not disabled.
• Run time increases when you use DYNALLOC to serialize data sets (as opposed to enqueue). This is because overhead is involved in a dynamic allocation and serialization across multiple processors.
