Do you have any tools like EASYEXIT?  Or ACC?  Or BMC Tools (use to be Stop-X37 
or PROSMS)?

In ISMF You can set up a class to include dynamic volume count. 

In SMS environment we see Seq and VSAM regularly take up to 100's of extents 
when a dataset is poorly allocated.

Do you use SMS for these datasets?

Do you work with your users on how to properly allocate a dataset?

My rule of thumb is small Primary and large Secondary with RLSE where possible.

Does anybody have a system exit that has the ability to increase the secondary 
allocation for a data set, after "x" number of extents?
