If the JCL specifies AMP=(‘BUFND=??, BUFNI=??’) how will CA Hyper-Buf perform the buffering in case the constraints table has AMPOVR=FORCE?
Any application that uses AMP= in their JCL should be reviewed closely and tested to be sure Hyper-Buf will not alter the buffers to a size that the application cannot utilize. This could cause abends.
With AMPOVR=FORCE then Hyper-Buf will decide what happens regardless of the JCL values.
With AMPOVR=GREATER then CA Hyper-Buf will review the AMP= statement and then based on that information, the Constraint Table information, and buffering recommendations internal to CA Hyper-Buf, the "greater" buffer the value will be used.
With AMPOVR=NO CA Hyper-Buf will do nothing and follow the AMP= values with no changes.
AMPOVR=NO if you have a lot of JCL with AMP= statements
AMPOVR=GREATER if you do not have much in the way of AMP= specified in JCL. These applications may require special attention or exclusion from Hyper-Buf.
