DFS253I hh.mm.ss TCU INOPERABLE LINE x PTERM y-z aa,bbbb,cc,dd, ee,ff,gg,hh,iiii,jjjj
Explanation
The 270X for LINE x PTERM y is inoperable. All PTERMs on the line have been marked inoperable, and the line has been placed in an idle state. See the information about the z/OS® system error message IEA000I for line and TCU errors or to IMS error message DFS973I for 3270 device errors.
Attention: The DFS253I form of the message is issued only for
remote 3270 lines.
Attention: IMS no longer supports BTAM
terminals.
The following description applies to remote
3270 lines:
- Code
- Meaning
- y-z
- This field gives the range of PTERMs that are connected to the line.
- aa
- This field contains the ECB completion code.
- bbbb
- The DECTYPE field indicates the type of failing operation.
- cc
- The DECTPCOD field indicates the data communication operation code from the last CCW run in the channel program.
- dd
- The DECFLAGS field contains the flag byte passed to IMS from BTAM. The field might contain information as to the cause of the failure.
- ee
- The DECSENS0 field contains the sense information from the DECB if the status in the CSW indicates a unit check.
- ff
- The DECERRST is the error status field from the DECB.
- gg
- The DECCSWST is the CSW status field from the DECB.
- hh
- This field contains the device-dependent module code. When the 3270 device-dependent module shuts down a component of the data communication network, a device-dependent module reason code is put in the CLBTEMP1 field to indicate why the device-dependent module shut down the component.
- iiii
- This field contains the BSCK return code. The code is passed from the BSC check routine (DFSBSCK0) to the device-dependent module. The BSC check routine analyzes the I/O completion and passes a unique return code to the device-dependent module, depending on the contents of the DECB fields.
- jjjj
- This field contains the SENSE/STATUS information from the 3270 device (if applicable).
