Explanation
Restart cannot proceed because of errors encountered.
In the message text:
- dddddddd
- The ddname of the data set being processed when the error was encountered. dddddddd can be blank.
- nnnnnnn
- The log sequence number last processed. nnnnnnn can be blank.
- xx
- A hexadecimal error code. Register 14 contains the address of
the routine that detected the error. Register 15 contains an error
code.
- Code (hex)
- Meaning
- 15
- Could not open the data set.
- 16
- Could not close the data set properly.
- 17
- Read error.
- 18
- Reread of last good block failed.
- 19
- OLDS block sequence error.
- 1A
- Next sequential log record was not found.
- 1B
- TRKCALC macro failed.
- 1C
- Latest OLDS could not be terminated.
- 1D
- Allocation of the log data set failed. Dynamic allocation failed, a DD statement is missing, or OPEN failed. The left half of Register 15 contains the DFSMDA return code.
- 1E
- Next log data set record was not found in the RECON data set, or the next OLDS is marked invalid.
- 1F
- Latest log data set record was not found in the RECON data set, or the next OLDS is marked invalid.
- 20
- Reusable OLDS is unavailable.
- 21
- Error return code from DBRC. Left half of register 15 contains the DBRC return code.
- 22
- A logic error was detected.
- 23
- Restart read transition table failure.
- 24
- A sequence error occurred on both OLDS (dual logging).
- 25
- A read error occurred on both OLDS (dual logging).
- 26
- In an XRF complex, the alternate system either allocated an SLDS or determined that the next log to be allocated is an SLDS. In a Fast Database Recovery environment, the Fast Database Recovery region either allocated an SLDS or determined that the next log to be allocated is an SLDS.
System action
IMS terminates with abend 0175. In an XRF complex, the IMS alternate system terminates with abend 0176.
In a Fast Database Recovery environment, the Fast Database Recovery region terminates with abend 0176.
Operator response
If this error occurred during Fast Database Recovery region initialization, take a simple checkpoint in the active system and make sure that the restartable checkpoint is found in the OLDS before restarting the Fast Database Recovery region.
