ddname DD name of the file
The message buffering facility was unable to open the dataset ddname for buffering messages while the TCP/IP connection to the OVOW server is down.
No message buffering will occur while the TCP/IP connection is down.
Verify that the DD name on the TCP SYSIN card for message buffering has a matching DD card in the VP390 startup JCL. Verify that the dataset named for that DD name is defined with the DCB values stated in the Ironstream for Micro Focus Universal Discovery for IBM Z Installation Guide. Recycle the VP390 job if any changes are made to the SYSIN cards or the startup JCL.
