FSUM2071I
An error occurred while the OMVS
command was writing to the debug
data set. No more debug
information will be recorded.+
Function = fwrite(),
return value = return-value,
errno = errno-decimal (X'errno-hex'),
reason code = reason-code,
description = 'system-message'

Explanation

The OMVS command was entered with the DEBUG option. The OMVS command was unable to write debugging information to the debug data set. This error may occur when the first data is written, or after some data has been written successfully.

In the message text:
return-value
The return value from the fwrite() function.
errno-decimal
The errno value, in decimal, returned from fwrite(). If errno is 0, no errno information is available for this error.
errno-hex
The errno value, in hexadecimal, returned from fwrite().
reason-code
The reason code returned from fwrite(); if errno is 0, this reason code value may be incorrect.
system-message
The system message corresponding to the returned errno value; if errno is 0, the displayed system message is not meaningful.

System action

The OMVS command does not record any more debugging data in the debug data set. The OMVS command tries to close the debug data set, but continues all other processing normally.

System programmer response

Make sure that the debug data set is set up properly. Follow any suggested actions for the errno or reason code displayed in the TSO/E second-level message.

For more information about the displayed errno value from the fwrite() function, see z/OS XL C/C++ Runtime Library Reference. For information about the return code from the fwrite callable service, see z/OS UNIX System Services Programming: Assembler Callable Services Reference.

User response

If the debug data is important, end the shell session and return to TSO/E. Make sure that the debug data set is defined as a sequential data set with fixed-length 80-byte records. If WRAPDEBUG(n) is not used, make sure that the data set has enough room for at least 10,000 80-byte records. If WRAPDEBUG(n) is used, make sure that the data set has enough room for at least n 80-byte records. If nothing appears to be wrong with the debug data set definition, contact the system programmer.
