Question:
Trying to open a file and receive the following error condition:
 
CAVO0200E VFAM INTERNAL ERROR, RETURN CODE=0CFB, REQUEST=0C
 
What does this  mean and how is it resolved?
Answer:
Usually, the cause was a GETVIS request for an MCB or MCT for a particular member. 

The breakdown of the message is as follows: 

return code = V$RETCOD --> x'0C', a VOLLIE internal error generated by + VFAM 
V$RETINF --> x'FB', indicates that the error was caused by a getvis problem 

request code = V$REQCOD --> x'0C', indicates that the request was for a member open 

To correct the problem in accessing the member in the future you might try this: 

1. Use the SET CLOSE commsnd against the member or members. 
2. Look at increasing SVA storage. 
3. The RELOAD command will re-allocate the file table. This should be done 
as a last resort. 

If this does not work you can recycling CICS in case SVA is short. Also, you may 
want to reorg (backup/restore) the OLL which is having problems.
