DBRC - Database Recovery Control service aids

Diagnostic service aids, including RECON record types, DBRC internal trace, DBRC external trace are described.

Diagnosing from a RECON list
You can use the LIST command to list the contents of all or part of the RECON data set.
RECON record types
The records in the RECON data set store information about logging activity and events that can affect the recovery of the database.
DBRC internal trace
DBRC internal trace is a useful tool for diagnosing problems that are possibly related to DBRC. The trace is always enabled.
Unformatted DBRC internal trace example
The module-call entries, module return entries, DSPURI00 trace entries, and other entries (such as GETFEED, DSPCRTR0, and CRTR0XIT) are shown in this trace example.
DBRC external trace
If you start the Generalized Trace Facility (GTF) and issue the CHANGE.RECON TRACEON command, the DBRC trace (DSPTRACE) creates an external trace record and issues the GTRACE macro to invoke GTF.
