ORA-00600 [17182] on Oracle 8.1.7.4.0 After a CTRL-C or Client Termination
Applies to:
Oracle Server – Enterprise Edition – Version: 8.1.7.4
This problem can occur on any platform.
Checked for relevance on 06-Mar-2007
Oracle RDBMS Server Versions prior to 9i
Symptoms
1. Intermittent heap corruptions errors like ORA-00600 [17182] are reported in the alert.log file.2. There is no impact to the database other than the process which encounters the errors getting killed.
3. From the trace file generated for this ORA-00600 error, check if the top few functions are :
kgherror kghfrf kkscls opicca
Cause
If the trace file shows that kkscls calls kghfrf, then it is related to:Bug 2281320 — ORA-600[17182] POSSIBLE AFTER CTRL-C OR CLIENT DEATH
Solution
The problem is when we call kghfrf to free a chunk of memory, we expect that this chunk to have been allocated from the Heap Memory and hence have a valid header, although internally we have used Frame Memory managed chunk. As a result, kghfrf errors out with the “Bagic Magic Number” in the Memory Chunk header error message.If you are running Oracle 8174, encounter this ORA-00600 [17182], and the call stack indicates the following functions { kgherror kghfrf kkscls }, then download and apply Patch 2281320 from MetaLink.
This issue has been fixed in Oracle Server 8.1.7.5 and later versions.
Note 2281320.8 is not limited to dblinks and can occur during normal database operation as well.
根據Oracle對ORA-00600 17182的官方解釋：
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)
4.solution
Ignore it.
