Job_queue_processes set to 0

Hi guys,
one question.
Next Weekend i have to migrate the database cluster from the old server onto new server but there is one Problem. How can i prevent that all database jobs are running after starting the database?
I read about the parameter job_queue_processes, you can set them to 0 and it prevents the run of each database job.
Is this right, and if yes is this true for dba_jobs and dba_scheduler_jobs?
best regards

Hi Mark,
Hi Pierre,
in this case i have to set job_queue_processes to 0 (disable all dba_jobs)
and to set MAX_JOB_SLAVE_PROCESSES to 0 with DBMS_SCHEDULER.SET_SCHEDULER_ATTRIBUTE.
+(In special scenarios a dba can still limit the maximum number of slaves to be started by the coordinator by setting the MAX_JOB_SLAVE_PROCESSES with the DBMS_SCHEDULER.SET_SCHEDULER_ATTRIBUTE procedure.)+
Is this right?
best regard and thanks for your fast response

How to set 'job_queue_processes' ?

Hello,
I have installed Oracle 10 on Linux RedHat Advanced Server 3, and during the database creation part of the install I got the message 'ORA-12547: TNS: lost contact' several times. At the end, I was told that the configuration failed because job_queue_processes must be greater than or equal to 1. I set job_queue_prcesses to 1 in init.ora When I ran emca to configure the database, I got the same error message at the end: "SEVERE: 'job_queue_processes' must be greater than or equal to 1'.
Am I setting job_queue_processes correctly ?
job_queue_processes = 1
Is it neccessary to shutdown and restart an oracle process before the new job_queue_processes setting can take effect ? If so, can someone please show me what to stop and restart ? If not, can someone please show me how to correctly set job_queue_processes ?
Thanks,
Colm.

Thanks for the response, I am new to Oracle, and I do not know in what context you are supposed to invoke the ALTER SYSTEM command. Is it after connecting to Oracle with sqlplus ? If that's the case, that won't work because I cannot connect; I am getting the following:
$ sqlplus /nolog
SQL> connect / as sysdba
ERROR:
ORA-12547: TNS:lost contact
SQL> alter system set job_queue_processes=10 scope=both
2 ;
SP2-0640: Not connected
The 'lost contact' message is what I was seeing during the Database Configuration part of the install.
Thanks,
Colm.

Problem in materialized view

Hello everybody!!!
I used the following script in order to see the automatic refresh of data contained in a materialized view.
I used the following script in SCOTT schema:
create materialized view log on emp
with rowid (job,sal)
including new values
create materialized view emp_mv
build immediate
refresh fast on commit
as
select job , sum(sal) sum_sal
from emp
group by job
The problem is that after i update the sal column (and commit it) of an employee and selecting from the emp_nv , I DO NOT see any difference , although the materialized view log has been updated successfully!!!
Under which circumstances the materialized view would be updated as well?
Simon.

What is job_queue_processes set to on your system? Materialized view refreshes are generally done as background jobs, so that initializiation parameter needs to be set to a non-zero value.

Materialized view with build deferred

Hello,
Do you have some idea why CREATE MATERIALIZED VIEW with BUILD DEFERRED option takes a lot of time? It's running 1 hour and not finish (Oracle 9.2).
CREATE MATERIALIZED VIEW mv_users
BUILD DEFERRED
REFRESH COMPLETE
NEXT SYSDATE+1
WITH ROWID
AS
SELECT usr_id, usr_type, usr_active, usr_brn_id, usr_first_name,
usr_last_name, usr_psl_rgn, usr_bp_id
FROM users@db_link;
Users table has 10 millions records.
Edited by: user12111171 on 2011-09-16 13:28

If the Job Queue is not enabled, the CREATE cannot auto-schedule the refresh. You need to have JOB_QUEUE_PROCESSES set to 1 or greater.
It would seem that when you say "I have created job to refresh the materialized view everyday using dbms_refresh.refresh" you haven't created a job using DBMS_JOB.SUBMIT (which is what the CREATE MATERIALIZED VIEW would do "behind the scenes" --- you can then query DBA_JOBS or USER_JOBS to see the auto-submitted job).

Job starts in un-scheduled time

Hi All,
I have created a job which runs fine for some days. But some times in runs in different time than what I scheduled. Here is the job script. It always suppose to run every day 5.00 PM.
Please advice on the same.
DECLARE
X NUMBER;
BEGIN
SYS.DBMS_JOB.SUBMIT
( job => X
,what => 'mypackage.myproc(''/u000/app/oracle/myfol'', ''NL''||TO_CHAR(SYSDATE-1, ''YYMMDD'')||''.TXT'', TO_CHAR(SYSDATE, ''YYYYMMDD''));'
,next_date => to_date('10/04/2009 17:00:00','dd/mm/yyyy hh24:mi:ss')
,interval => 'TRUNC(SYSDATE + 1) +17/24'
,no_parse => TRUE
SYS.DBMS_OUTPUT.PUT_LINE('Job Number is: ' || to_char(x));
END;
commit;

But some times in runs in different time than what I scheduled.What time are you seeing it run? Are we talking about major changes (i.e. it's running at 3 AM)? Or problems where it is running a few minutes after 5 PM?
Do you have other jobs? What is JOB_QUEUE_PROCESSES set to? Any chance there are more jobs that want to run at 5 than JOB_QUEUE_PROCESSES allows to run simultaneously at 5 so your job is getting queued?
Is the clock on the server correct? Is the clock drifting over time?

Replication - Single Master DB

Hi
I have a DB running on Server 1 and I want to create replication of all the Objects(existing Tables and any new table created) from Server-1 to Server-2.
I want One-Way replication only and it should be SYNC with SERVER 1, So Whats the best Replication approach ? Whats the performance impact. Please let me know if there is any tutorial available.
INFO
1. DB on Server 1 has 125 Tables.
2. The idea behind this that there are bunch of users who wants to query the DB , so we want to bring the same datbase running on SERVER 1 to another SERVER II , so that there want be any IO sharing between the PRODUCTION USER and QUERY USER.
Thanks
JR.

1. FAST REFRESH ON COMMIT cannot be done across a DBLink. I've explained this a few times in this forum. An ON COMMIT operation is a push operation : thus when the source table is updated by DML it has to push the updates to the MV. Since an MV across databases is via a DBLink that allows the TARGET to connect to the SOURCE and query the SOURCE, the SOURCE has no way to push the updates.
See http://hemantoracledba.blogspot.com/2008/06/mvs-with-refresh-on-commit-cannot-be.html
2. When you create an MV with a Refresh Interval, Oracle automatically submits a Job in the DBA_JOBS queue. This job does the actual refresh. Query USER_JOBS in the target (SERVER-2) database to check the job. Most likely, your SERVER-2 database has "job_queue_processes" set to 0 which disables running of jobs. You need to issue an
ALTER SYSTEM SET JOB_QUEUE_PROCESSES=1;in the target (SERVER-2) database so that it can run the Refresh job that will pull the updates.
(You could set job_queue_processes higher if you are going to run multiple refresh's in parallel).
On problem I foresee with your step to use MVs is that seperate MVs on individual tables will not synchronise data across the MVs.
If a transaction in the source database updates two tables "A" and "B" and the target database server uses two seperate refresh's for the two MVs "MV_A" and "MV_B" then "MV_A" and "MV_B" will not be synchronised to the same point in time (ie transaction).
You have to use Refresh Groups. MVs for all the the tables that could potentially participate in a transaction must be in the same Refresh Group and the Refresh job would be defined at the Refresh Group level . A problematic side effect of using Refresh Groups is that , in order to make the MVs transactionally consistent, Oracle must use DELETE and INSERT operations on all the MVs in the group. This will take time and generate significantly more UNDO and REDO in the Targer (SERVER-2) database.

APEX_PLSQL_JOB problem - jobs ignored

After successful creation of before header process it looks like the job gets ignored.
This is the process code:
declare
l_job integer;
begin
l_job:=APEX_PLSQL_JOB.SUBMIT_PROCESS
('insert into t values (5);',sysdate,'nocomment');
end;
APEX_PLSQL_JOBS view has no entry of this job while "wwv_flow_jobs" table shows submitted job with system status "COMPLETE".
Table T stays empty, and after the page load I get "success" message that I set up before on the process definition page.
I am working on APEX 2.2 with job_queue_processes set to 10.
No error messages in database alert log.
What could go wrong ?
Is there a way to purge wwv_flow_jobs table ( or APEX_PLSQL_JOBS view if entries exist) ?

Oc4j scheduled jobs management

We have an application deployed under oc4j server and that launches scheduled jobs.
When we restart the oc4j server, old jobs are relaunched automatically which generate exception. Is this behavior logical? How we can remove these jobs.
Thanks for collaboration

Hi,
Some diagnostic things to check
- are there any crashes reported in the alert.log ?
- are any jobs running
select * from dba_scheduler_running_jobs;
- is the job coordinator running
on UNIX
ps aux |grep cjq
select program from v$session; -- look for CJQ
- are job slaves running
on UNIX
ps aux |grep j0
select program from v$session; -- look for J0*
- on UNIX what process is consuming the CPU (check output of top and then grep the output of "ps aux" for the process ID)
- what is MAX_JOB_SLAVE_PROCESSES set to ?
select * from all_scheduler_global_attribute where ATTRIBUTE_NAME='MAX_JOB_SLAVE_PROCESSES';
- what is job_queue_processes set to ?
select value from v$parameter where lower(name)='job_queue_processes';
- what is the status of all enabled jobs
select job_name, state, next_run_date, last_start_date from dba_scheduler_jobs
where state!='DISABLED';
If scheduled jobs are not running and there are no jobs running, there is really nothing to "reset", it's just a matter of figuring out why jobs are not running. If you provide answers to the questions above, it should become clearer what is happening.
One thing you can try is disabling all jobs and reenabling them one by one to see if they run.
The purge_log job running more than a day is extremely unusual, but it shouldn't step on itself as it will just skip the next run if it is already running.
Hope this helps,
Ravi.

Help needed for hash_area_size setting for Datawarehouse environment

We have an Oracle 10g Datawarehousing environment , running on 3 - node RAC
with 16 GB RAM & 4 CPUs each and roughly we have 200 users and night jobs running on this D/W .
We find that query performance of all ETL Processes & joins are quite slow .
How much should we increase the value of hash_area_size parameter for this Datawarehouse environment ? This is a Production database, with Oracle Database 10g Enterprise Edition Release 10.1.0.5.0.
We use OWB 10g Tool for this D/W and we need to change the hash_area_size to increase the performance of the ETL Processes.
This is the Oracle init parameter settings used, as shown below : -
Kindly suggest ,

Precautions i need to take when changing the Character set

Hi,
ORACLE VERSION: 10G Release 1 (10.1.0.3.0)
I am going to change my database's characterset from AL32UTF8 to WE8MSWIN1252 character set and AL16UTF16 NCHAR character set. So i have few questions for you.
1. What is the difference between Character Set and National Character set? Do i have to set both?
2. What are precautions that i need to take while changing the characterset?
3. What are JOB_QUEUE_PROCESSES and AQ_TM_PROCESSES parameters in Plain English? Why do i have to set these parameters to 0 as mentioned in this post below.
Storing Chinese in Oracle Database

1) The database character set controls (and specifies) the character set of CHAR & VARCHAR2 columns. The national character set controls the character set of NCHAR & NVARCHAR2 columns.
2) Please make sure that you read the section of the Globalization manual that discusses character set migration. In particular, going from UTF-8 to Windows-1252 is going to require a bit more work since the latter is a subset (and not a strict binary subset) of the former.

Oracle 11g Installation How to select Database Character Set

Hi,
I am Installing oracle 11g R2. After installation I had verified the character set it was AL16UTF16 but I wants to set AL32UTF8 charater set at the time of oracle installation only. I can't see the character set setting opetion at the time of installation because I am selecting the installation option " Install database softerware only" and after installation of oracle software manually I am creating the database. Please help me how can I set the character set at the time of oracle installation or at the time of database creation.
My question is-
How can I set the AL32UTF8 character set in above scenario?
Why It is showing AL16UTF16 character set even I did not define any thing?

But is there any choice to set the NLS_CHARACTERSET at the time of manually database creation. Actually For creating the database i am using one shell script for seting the parameter values in init.ora file so can I set the parameter at that level(at the time of creating init.ora using manually database creation). like

How to set maximum number of jobs in oracle

Could pls tell explain me about how to set maximum number of jobs in oracle....
Regd,
Mahi

I don't think there is any limit on number of jobs that can be submitted to Oracle. However, there is a limit on the number of processes that would execute those jobs (governed by JOB_QUEUE_PROCESSES).

Typo corrected.

Job_queue_processes

Hi friends
I have a BD that it has created several jobs, 5 of which they execute themselves to 1:00am and the parameter job_queue_processes is 1. I see in DBA_JOBS view and apparently executes all jobs without problems and in simultaneous form.
i dont understand that because i read in another web page that for my case, for example, the parameter must have a value greater to 5, than are jobs that is executed in simultaneous.
Anyone can explain me?
...and i read the oracle documentation about that, that is the reason for my question.
thanks in advance.
Cesar

Hi Cesar,
Can Anyone can explain me? Probably not, but I'll try!
Me, I just set it to a large-enough value and leave it be . . .
Dr. Hall has these notes on setting job_queue_processes from his book "Oracle Job Scheduling":
http://www.remote-dba.cc/t_jobscheduling_18_Oracle9i_scheduler_.htm
the job_queue_processes parameter sets an upper limit for the number of job slaves that can be spawned to execute jobs. The value assigned must be between 0-1000; with zero being the default.
The job coordinator spawns as many job slaves (j000 to j999) as are needed to execute the outstanding jobs, making the job_queue_processes parameter redundant in Oracle 10g. A job slave gathers metadata from the scheduler tables to enable it to execute a job. Upon completion of a job, the slave process updates any relevant information in the job table, inserts data into the job run history and requests another job from the job coordinator. If a job is not available, the job slave sleeps until there is work to do. The job coordinator periodically terminates idle job slaves to reduce the slave pool.
Hope this helps. . .
