Compile the Invalid JAVA component in Oracle Database

During patching activity, i got my java component invalid.
So i tried to utlrp.sql alone but it doesn’t help.

col comp_id for a10
col version for a11
col status for a10
col comp_name for a37
select comp_id,comp_name,version,status from dba_registry;

Following are the steps for compiling java components:

1. Check the current value of hidden parameter “_system_trig_enabled”.

col name for a20
col value for a5
col description for a27
select x.ksppinm name,
y.ksppstvl value,
ksppdesc description
from x$ksppi x,
x$ksppcv y
where x.inst_id = userenv('Instance')
and y.inst_id = userenv('Instance')
and x.indx = y.indx
and x.ksppinm = '_system_trig_enabled';

NAME                 VALUE DESCRIPTION
-------------------- ----- ---------------------------
_system_trig_enabled TRUE  are system triggers enabled

2. Note down the current value of java_jit_enabled parameter.

show parameter java_jit_enabled

NAME               TYPE     VALUE
------------------ -------- ------
java_jit_enabled   boolean  TRUE

3. Check the value of JOB_QUEUE_PROCESSES.

select * from v$parameter where name='JOB_QUEUE_PROCESSES';
no rows selected
-- And
Show parameter job_queue_processes

NAME                  TYPE      VALUE
--------------------- --------- -------
job_queue_processes   integer   4000

4. Change the value of these parameter as sysdba user.

alter system set "_system_trig_enabled" = false scope=memory;
alter system set java_jit_enabled=false;
alter system set JOB_QUEUE_PROCESSES=0;

5. Execute the java system command which compile java components.

create or replace java system
/


6. Rollback the changed parameter in steps 4 to upper value.

--Revert the value of _system_trig_enabled, JOB_QUEUE_PROCESSES and java_jit_enabled.
alter system set "_system_trig_enabled" = TRUE scope=memory;
alter system set java_jit_enabled=TRUE;
alter system set JOB_QUEUE_PROCESSES=4000;


7. Run utlrp.sql to validate any invalid Java objects.

@?/rdbms/admin/utlrp.sql


8. Check the Java version that everything seems good if it executed successfully.

SELECT dbms_java.get_ojvm_property(PROPSTRING=>'java.version') FROM dual;


9. Check the Java components in registry that all become valid.

col comp_id for a10
col version for a11
col status for a10
col comp_name for a37
select comp_id,comp_name,version,status from dba_registry;
