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 summary
**************************************************************** USERS AFFECTED: users on platforms. **************************************************************** PROBLEM DESCRIPTION: Oracle Enterprise job gives ** malloc(): memory corruption: 0x0a004590 *** **************************************************************** RECOMMENDATION: use patch provided. This change is included in 8.1 Fix Pack 1. ****************************************************************
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
