Explanation
The error occurred during processing of backspace.
In
the message text:
- rc
- Associates this message with system completion code 145 and with
the return code.
- x
- GTRACE indicator.
- 0
- A trace record has been written to the SYS1.TRACE data set.
- 1
- An unsuccessful attempt was made to trace data; GTRACE was not
active.
- 2
- An unsuccessful attempt was made to trace data; the GTRACE buffers
were full.
- 3
- No information has been traced.
- jjj
- Job name.
- sss
- Step name.
- ddname
- DDname, or ******** if unable to locate the DDname.
The explanation for the hex return code is as
follows:
- Return Code
- Explanation
- 01
- The DCB whose address was supplied in register 1 is not in the
caller's region.
- 02
- The DCB does not point to a valid DEB or the DEB does not point
back to the DCB.
- 03
- The device type field in the DCB is incorrect.
- 04
- The DCB contains an incorrect entry pointer to the device characteristics
table.
- 05
- Normal scheduling; the DCB does not point to a valid IOB or the
IOB pointed to by the DCB does not point to a valid IOB within the
caller's region.
- 06
- Chained scheduling; the DCB does not point to a valid main IOB
within the caller's region.
- 07
- Chained scheduling; the DCB, or the ICB pointed to by the DCB,
does not point to a valid ICB within the caller's region.
- 08
- Chained scheduling; the ICBs are not correctly chained together
or the value of DCBNCP is less than the number of ICBs. Normal scheduling;
same error in IOBs for chained scheduling.
System action
The backspace task recovery routine has been invoked.
If the caller's DCB, main IOB, and first ICB for chained scheduling,
or first IOB for normal scheduling are in his region, an attempt was
made to trace them to the SYS1.TRACE data set.
System programmer response
If the error recurs and the program
is not in error, look at the messages in the job log for more information.
Search problem reporting data bases for a fix for the problem. If
no fix exists, contact the IBM® Support
Center. Provide the JCL and the program listing for the job.
Programmer response
Probable user error. Verify that register
1 contained the correct DCB address prior to issuing BSP and that
the DCB has not been overlaid since being opened. If the DCB is valid,
verify that it contains the correct IOB and/or ICB addresses and that
neither the IOBs and/or the ICBs have been overlaid.
