JIT compiler parameter in Oracle

There is one parameter in 11g which caused our system to crash with:

ORA-00449: background process 'LGWR' unexpectedly terminated with error 313
ORA-07445: exception encountered: core dump [ioc_pin_shared_executable_object()+1519]

The culprit is one DB parameter that Oracle support recommended to alter:

- java_jit_enabled

JAVA_JIT_ENABLED enables or disables the Just-in-Time (JIT) compiler for the Oracle Java Virtual Machine (OracleJVM) environment

The JIT is a compiler that has been introduced in 11g for faster compilation of java code

Current value:

- true

Recommended value:

- false

The parameter can be modified with no downtime.

# sqlplus / as sysdba
alter system set java_jit_enabled = false scope=both;
