Examples of DBRC router processing and RECON I/O error processing output

Formatted and unformatted output for DBRC router processing and RECON I/O error processing are shown.

DBRC external trace output

The following two examples show the unformatted and formatted output for DBRC router processing and RECON I/O error processing.

In the following figure:

  • DBRCJOB1 is the job name.
  • TIME is the time stamp of the trace entry.
  • DSPCRTR0 passed control to the next routine to process the request identified by the DFSBRLSB.
  • RQB is the address of the request level control block.
  • LSB is the address of the DFSBRLSB.
  • FUNC indicates the function flags (from the BRLBFFLG field of the DFSBRLSB).
  • EXIT indicates the exit flags (from the BRLBEFLG field of the DFSBRLSB).

In the following figure, a SHOWCB macro instruction is executed after the I/O request is issued.

  • IMS1 is the SYSID.
  • TIME is the time stamp of the trace entry.
  • DSPURI00 has control.
  • RQB is the address of the request level control block.
  • A locate was done. For a locate, a flag and record key are also shown in the trace record.
  • RSCD is the VSAM reason code.
