Explanation
The installation is not taking advantage of allowing SDUMP to automatically allocate its dump data sets.
System action
SDUMP will either use an available pre-allocated SYS1.DUMPxx dump data set or leave the dump captured in virtual storage. This use of virtual storage can negatively impact the paging subsystem.
Operator response
Report this information to the system programmer.
System programmer response
IBM® Suggestion: See the "Using Automatically Allocated Dump Data Sets" section of z/OS MVS Diagnosis: Tools and Service Aids for setup information. One advantage is the efficiency of using a system determined blocksize to write the dump to DASD. Another benefit is the dump will always fit into the space allocated for the data set.
