how to rebuild the wf_java_deferred queue

Followings steps are to be followed to rebuild the queue
1. Check to see what records will be backed up on the wf_queue_temp_jms_table backup table.
select wfjd.corr_id corrid, msg_state state, count(*) COUNT
from applsys.aq$wf_java_deferred wfjd
where msg_state IN(‘READY’, ‘WAIT’)
group by corr_id, wfjd.msg_state;

2). Shutdown the Workflow Agent Listener Service and backup the records on the WF_JAVA_DEFERRED queue to the apps.wf_queue_temp_jms_table backup table.

System Administrator > Oracle Applications Manager > Workflow > Service Components > Workflow Agent Listener Service

sqlplus apps/ @wfaqback.sql

For Example:

sqlplus apps/apps @$FND_TOP/sql/wfaqback.sql WF_JAVA_DEFERRED

3). Make sure all the records are in the wf_queue_temp_jms_table table.

select CORR_ID corrid, QUEUE queue, count (*)
from apps.wf_queue_temp_jms_table
group by CORR_ID, QUEUE;

4). Set aq_tm_processes =0.

alter system set aq_tm_processes=0;

5). Note the name of the tablspace containing index on CORRID that will need to be recreated later.

SELECT index_name, tablespace_name
FROM all_indexes
WHERE index_name = ‘WF_JAVA_DEFERRED_N1’;

6). Drop the WF_JAVA_DEFERRED queue and queue_table.

declare

begin
dbms_aqadm.stop_queue(queue_name => ‘APPLSYS.WF_JAVA_DEFERRED’, wait =>
FALSE);
end;
/

declare

begin
dbms_aqadm.drop_queue_table(queue_table => ‘APPLSYS.WF_JAVA_DEFERRED’, force
=> TRUE);
end;
/

7). Recreate the WF_JAVA_DEFERRED queue.

sqlplus / @wfbesqc.sql

For Example:

sqlplus apps/apps @$FND_TOP/patch/115/sql/wfbesqc.sql APPLSYS APPS

8). Add the subscribers.

sqlplus APPSusr/ @wfbesqsubc.sql

Example Syntax:

sqlplus apps/apps @$FND_TOP/patch/115/sql/wfbesqsubc.sql APPLSYS APPS

9). Recreate the index (Please ignore any ORA-00955 errors about object already exist as this adds index for other objects.):

sqlplus APPSusr/ @FND_TOP/patch/115/sql/wfbesqidxc.sql APPLSYS APPS tablespace_name

Example Syntax:

sqlplus apps/apps @$FND_TOP/patch/115/sql/wfbesqidxc.sql APPLSYS APPS APPS_TS_QUEUES

10). Put the data for the WF_JAVA_DEFERRED back into the queue.

sqlplus apps/ @wfaqrenq.sql

For Example:

sqlplus apps/apps @$FND_TOP/sql/wfaqrenq.sql WF_JAVA_DEFERRED

11). Confirm that all records are back on the queue.

select wfjd.corr_id corrid, msg_state state, count(*) COUNT
from applsys.aq$wf_java_deferred wfjd
where msg_state IN(‘READY’, ‘WAIT’)
group by corr_id, wfjd.msg_state;

12). Start the Workflow Agent Listener Service and confirm it is now processing the events on the queue.

System Administrator > Oracle Applications Manager > Workflow > Service Components > Workflow Agent Listener Service

select wfjd.corr_id corrid, msg_state state, count(*) COUNT
from applsys.aq$wf_java_deferred wfjd
where msg_state IN(‘READY’, ‘WAIT’)
group by corr_id, wfjd.msg_state;
