Performing an upgrade from CA DB2 Tools r17 to r20 the Post-Install process for IDB2 encounters the failure:
WRNG.LEN.RECORD IDC3003I FUNCTION TERMINATED. CONDITION CODE IS 12
When copying the r17 Profile dataset to the new r20 version.
The r17 REQUESTS PDS library was incorrectly specified as the input file, and it should have been the r17 VSAM PROFILE dataset.
Trying to REPRO a PDS to a VSAM file is not supported. The r17 input file for this process must also be a VSAM file.
