00C90102   

Explanation

An inconsistent page was detected. This has been caused by a DB2® internal error.

System action

A record is written to SYS1.LOGREC, and an SVC dump is requested.

System programmer response

If you suspect an error in DB2, you might need to report the problem. For information about identifying and reporting the problem, see Collecting diagnostic data.

Problem determination

SYS1.LOGREC contains information in the variable recording area (VRA) of the system diagnostic work area (SDWA). Significant fields for this code are: VRARRK5, VRARRK6, VRARRK7, VRARRK8, and VRARRK9.

In addition, the following general purpose registers (GPRs) contain the indicated diagnostic information:
GPR
Content
2
Address of the page set block (PB)
3
Address of the log record, if any
8
Address of the buffer block (BB)
9
Address of the page buffer
Collect the following diagnostic items:
  • Console output from the system on which the job was run, and a listing of the SYSLOG data set for the period of time that spans the failure.
  • Dynamic dump, taken to SYS1.DUMPxx data set, by DB2 (04E and 04F abends).
  • Listing of SYS1.LOGREC data set, obtained by executing IFCEREP1.
  • Listing of DB2 log output.
  • Dump of the index or table space that failed.
  • SYSPRINT output, including JCL, for the application program or batch job, and system messages that were issued. Make sure that MSGLEVEL=(1,1) on the JOB statement so that all diagnostic information is sent to SYSPRINT.
