Hi,

Recently we upgraded our database from 10.2.0.4 to 11.1.07, after some time we encountered error ORA-07445 in our alert log. At the same time we were getting errors at OS level as :

In alert log:

Exception [type: SIGSEGV, Invalid permissions for mapped object] [ADDR:0xFFFFFFFF7FFED1E0] [PC:0xFFFFFFFF7FFED1E0, {empty}]

on analysis we found that whenever user running "Process transaction interface" request all child requests "inventory transaction worker" are getting error out.

Whenever we submit this is request it is shutting down the Inventory manager.


Solution:

In oracle database 11g parameter java_jit_enabled is by default true. We changed this parameter to false.

After setting this value we restarted our database and issue resolved.
