EQA9915E EQADPFMB invalid recordsize. File must be rebuilt. See SEQASAMP(EQAWCRVS).

Explanation
The DTCN VSAM Repository data set EQADPFMB has an incorrect record size for this version of
z/OS® Debugger. This could be because it was created
for an older version of z/OS Debugger than the one
that is in use.

Response
Allocate and use a new EQADPFMB data set using the JCL in member EQAWCRVS of the SEQASAMP data
set for the version of z/OS Debugger that is in use.
Also consider using the JCL in member EQADPCNV of the SEQASAMP data set to convert EQADPFMB profiles
from previous versions of z/OS Debugger to the new
format.
