JR32014: ORACLE ENTERPRISE STAGE ABORTS JOB WITH STACK TRACE BEGINNING WITH: *** GLIBC DETECTED *** OSH: MALLOC(): MEMORY CORRUPTION

APAR status

• Closed as program error.

Error description

• Simple two stage job with oracle enterprise source stage and
  peek target stage will abort immediately with a stack trace that
  begins with *** glibc detected *** osh: malloc(): memory
  corruption: 0x084ecd78 ***
  
  The remainder of the stack trace will show that the error occurs
  in a call to malloc that originates from the function within the
  oracle enterprise stage that is being called to make the
  connection.
  
  The issue occurs when the remote server property contains a long
  connection string value.
  

Local fix

• Use a connection string that is shorter than 128 bytes
  
  This fix is included in 8.0.1 fix pack 3

Problem conclusion

• The server argument from osh command line is held in a char
  [128] buffer, which is generally ample.
  But it fell short in a case where a customer gave some thing
  (legal of course ) like:
  
  -server
  '(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=checker
  s.crackerbarrel.com)(PORT=1530)))(CONNECT_DATA=(SERVER=DEDICATED
  )(SERVICE_NAME=DW01D)))'
  
  The buffer over run caused user to receive a message on memory
  corruption.
  We have made the buffer dynamically sized to avoid such buffer
  over runs.
  

Temporary fix
