PURPOSE:
This article discusses the internal error "ORA-600 [17112]", what
it means and possible actions. The information here is only applicable
to the versions listed and is provided only for guidance.

ERROR:
ORA-600 [17112][a][b][c][d][e]

VERSIONS:
versions 7.3.X to 8.1.X

DESCRIPTION:

Oracle has detected that the magic number in a memory chunk header has
been overwritten.

This is a heap (in memory) corruption and there is no underlying data
corruption.

The error may occur in the one of the process specific heaps
(the Call heap, PGA heap, or session heap) or in the shared heap (SGA).

ARGUMENTS:
Arg [a] Pointer to chunk header

FUNCTIONALITY:
HEAP MANAGEMENT

IMPACT:
PROCESS FAILURE
MEMORY CORRUPTION, POSSIBLE INSTANCE FAILURE.
NON DATA CORRUPTIVE - No underlying data corruption.

SUGGESTIONS:
This is likely to be an effect rather than the cause
of the problem. May be due to an Operating System (OS)
memory overwrite. Run diagnostics to check the physical
memory on the machine and check the OS system logs.
For repeatable occurrances, please submit the trace
files and alert.log to Oracle Support Services for further analysis.
