Goal

This note collects all known Database Gateway for DRDA (DG4DRDA / DG4DB2) release 11.2 core dumps and (if possible) a way how to resolve them.

Before analysing core dumps you need to make sure the gateway Oracle_Home contains a log directory in $ORACLE_HOME/rdbms. If this directory does not exist, please manually create it. This allows you to collect all generated core dumps including the gateway trace files corresponding to the core dump in the $ORACLE_HOME/rdbms/log directory. Else the core dumps are created in the directory where you've started the gateway listener.

 

Core dumps can be analysed platform specific utilities like gdb, dbx etc. Details about which platform supports which dump utility can be found in note <Note 1812.1>.

On Linux for example the utility is gdb and to analyse a Linux core you need to execute:

gdb $ORACLE_HOME/bin/dg4db2 <core file name>

use the gdb command "where" to collect relevant core dump info.
