HIS018I   ERROR WRITING FILE filename. SOME INSTRUMENTATION DATA CANNOT BE WRITTEN.

Explanation

Hardware instrumentation services (HIS) encountered an error writing to the identified instrumentation file while processing a MODIFY hisproc command. Fewer data bytes than requested are written. It might be caused by one of the following reasons:
  • The amount of data to be written is greater than the remaining space on the output device.
  • The amount of data to be written is greater than the file size limit for the process.

In the message text:

filename
The name of the output data file in UNIX System Services file format.

System action

The system failed the MODIFY hisproc command. The identified file is only partially created. The file might not contain useful information.

Operator response

Verify that sufficient disk space is allocated to the identified UNIX Systems Services file, and that the file size limit for the process is not exceeded. Issue the DISPLAY OMVS,OPTIONS command to list the current limit value of MAXFILESIZE. If necessary, increase the MAXFILESIZE value using the SETOMVS MAXFILESIZE=nnnn system command.

System programmer response

If the identified file has insufficient disk space, prepare additional disk space available to the file directory. If the error is caused by the file size limit, increase the limit by issuing a SETOMVS MAXFILESIZE=nnnn system command. See z/OS MVS System Commands for details.

Problem determination

None.
