Handling errors in VSAM files in RLS mode
If your application accesses a VSAM
data set in RLS mode, be sure to check the file status
and VSAM
feedback codes after each request.
About this task
If your application encounters "SMSVSAM server not available"
while processing input or output, explicitly close the VSAM file
before you try to open it again. VSAM generates return code 16 for
such failures, and there is no feedback code. You can have COBOL
programs check the first 2 bytes of the second file status area for
VSAM return code 16. The COBOL run time generates message IGZ0205W
and automatically closes the file if the error occurs during OPEN processing.
All other RLS mode errors return a VSAM return
code of 4, 8, or
12.
