I was under the impression that I could document and maintain Adabas databases and files residing on both zOS and Windows from within a single instance of Predict 4.5.2 on the mainframe, and I see nothing in the documentation to contradict this. Am I mistaken? Specifically, I want to perform COMPARE AF and GENERATE AF to a Windows-based Adabas database.

Here’s the configuration:  
zOS 1.10  
Win2003 Server  
ADA617 & 621  
NAT423 & 425  
PRD452  
WCP621 (mf)  
WCP733 (win)

I’ve defined the Windows-based database, but when I try to incorporate files, I receive  
DIC2682 ADABAS RESPONSE CODE ’ 50 ’ RECEIVED.  
This is a record buffer error.

Of course, for COMPARE AF, I get  
DIC2085 NO FILES SATISFYING THE SEARCH CRITERION ARE CONNECTED

When I attempt a GEN AF, I get  
NAT3146 Invalid buffer length. DB/FNR/Subcode / /:3:.

These response codes look very much like Predict is issuing ACB calls but Adabas is expecting ACBX (or vice versa). The documentation states that a 6.2 database cannot be reached without WCP733, but while on the mainframe I am able to ping databases and retrieve FDTs from both 6.1 and 6.2.

Any ideas?
