Restarting oracle background process

Hi all,
How can I restart an oracle background process "database writer" (ora_dbw0) without
restarting the oracle database?
Can I use "kill -HUP PID"?
Thanks alot.
George

if database statrts up without any intervention, no recovery is needed.
but to be on the safe side, check SM21, ST22 and SM37 for cancelled jobs.

RMAN DUPLICATE and Restarting dead background process

Hi,
Has anyone come across the problem in 10.2.0.3 where there are continuous errors in the alert log :
Restarting dead background process QMN0
QMN0 started with pid=9?
I see this is a bug in Oracle 9 but was supposed to be fixed by 10. I have tried the solution for the Oracle 9 bug : ALTER SYSTEM SET aq_tm_processes=1; but no joy
This error started in the target database after I used RMAN -DUPLICATE to create another test database on the same server. The source is a 10.2.0.3 database with parameter compatibility set to 9.2.0.
Thanks

I have tried changing the compatibility parameter (on advice from Oracle Support) i.e. compatibility=10.2.0 on the target database but this has made no difference

Oracle background process dying

Hi
I was wondering if anyone else had seem this problem and had any
solutions on it?
We have Oracle 8.0.5 install on Redhat, the install process went
through smoothly and everything runs okay to the best of our
knowledge and we have three instances running on the machine more
for testing than any production work, yet! Also one of the
instances has webdb installed on it.
Okay the problem we are seeing is as follows, we startup the
databases and leave them up but when we come back to the system
and check the system with the 'ps ax' command a number of the
background processes have disappeared, initially smon & dbwr but
this is not always the case and I have come back to the system to
see only two of the original six processes running sometimes we
are still able to connect to the database and do selects and
updates, etc but normally we have to shutdown and restart the
instances. There are no error logs generated and I've checked all
the relevant directories i.e. bdump, udump, etc and right now we
are at a loss to discover the problem.
My concern at the moment is not wanting to put a production
system on this without being able to firstly identifiy the
problem or to solve it.
Any feedback would be appreciated.

Thanks I'll give that a try

Many thanks

First the suggestion always include OS and database version, that's a great help. Since I don't have this information, only a vague guess: it could be bug

As a workaround set AQ_TM_PROCESSES=0. Don't do this when Oracle Streams is used.

Restarting dead background process EMN0

I'm running oracle 9.0.1.4 database on SunOS 5.8 and have serious problem: sometimes database restarts with following message in alert.log file:
"Restarting dead background process EMN0"
Then, database shutdown (immediate, close normal) and startup normal.
No additional information is available in any of trc files.
Can anybody help?
Thanks.

Please help, i'm still in trouble.
No one has encountered this error before?
The strange this is i'm not able to connect with sqlplus directly from the server.
On that server i have other 3 oracle instances which are running without problems and on which i can connect successfully.

Oracle 9i background process

Hi,
Currently I am doing ORACLE 9i Data Guard on HP-UX, I find there are some strange background process, such as "nsv1", "lns0" and "rsm0". I am familiar with smon, pmon, etc, but those new processes are new to me. I researched Oracle doc and Metalink, there is no place talking about those processes.
Do you know any place I can get explanation of all the Oracle background process?
Thanks

Here is a quick description directly from the database:
TEST> select name, description from v$bgprocess where name in ('NSV1','LNS0','RSM0');
NAME DESCRIPTION
LNS0 Network Server 0
RSM0 Data Guard Broker Resource Guard Process 0
NSV1 Data Guard Broker NetSlave Process 1Yoann.

Regarding Background processes

Hi,
I need information regarding the Oracle background processes how it works internally step by step process for all the Background Processes and kindly tell me is their any duration for all the processes and kindly tell me is their online site so that i can learn and tell me how do we manage the tablespaces and i do not know sql kindly tell me how to learn sql and pl/sql?if you provide me the link for all these i would be garteful.

Abnormal increment in background processes on AIX unix (oracle8i)

Hi
We have a problem running oracle8i on AIX unix. Our system is having two
parallel IBM RS6000 servers. Both running in HACMP env. We are using oracle8i with almost 350 clients.
For the last few days we observed that total no of oracle background processes abnormally increasing and touches 400 on each server. We got this information from following command
ps -ef |grep ora |wc -l
The moment it reaches 400 no more sessions are able to connect to the database.
One more thing we have observed that about 150 processes are defunct, which we get from using following commands
ps -ef |grep defunct | wc -l
On killing these processes using
kill -9 <pid>
system is unable to kill it.
When we query from v$session connecting to each servers we hardly found total number of sessions more than 225 on each server.
If anybody has any idea why so many processes are spawned and how to control them please mail me the solution. Or if u require some more information about the system and oracle parameters please let me know. My email_id is
[email protected]
Thanks
SHAKEEL AHMAD

You compare v$process with v$session.
If you have any defunc process, they wont appear in the v$session. But, they resides in the v$process. You need to kill them from the os prompt.
SELECT spid
FROM v$process
WHERE NOT EXISTS ( SELECT 1
FROM v$session
WHERE paddr = addr)
This query gives the osid of all the defunc process and kill them using kill -9 on os.
Are your connection coming from jdbc? Also, you can make use of DCD Dead Connection Detector.

Oracle Application Services Background Processes

Hi all,
Can any one list the Oracle Application services background processes.
adopmnctl.sh
adalnctl.sh
adapcctl.sh
adoacorectl.sh
adformsctl.sh
adoafmctl.sh
adcmctl.sh
jtffmctl.sh
Ex: adcmcttl.sh ---> FNDLIBR
Thanks,
Ramaraju

Hi Ramaraju,
You can identify the background process as below:
For - adopmnctl.sh | adapcctl.sh | adoacorectl.sh | adformsctl.sh | adoafmctl.sh
./adopmnctl.sh status -l
For Example :
Above command will give you the process id (Refer pid column) as shown below:
---------------------------------+--------------------+---------+----------+-
ias-component                    | process-type       |     pid | status   |
---------------------------------+--------------------+---------+----------+-
OC4JGroup:default_group          | OC4J:oafm          |   13457 | Alive    |
OC4JGroup:default_group          | OC4J:forms         |   13386 | Alive    |
OC4JGroup:default_group          | OC4J:oacore        |   13234 | Alive    |
HTTP_Server                      | HTTP_Server        |   13177 | Alive    |
ps -ef|grep <pid>
For - adalnctl.sh -
ps -ef|grep lsnr

What is restarting my ora processes after a crash ?

Hey,
my standby database crashed from time to time.
It looks like an fragmentation error in the SHARED_POOL_SIZE parameter. ORA-04031 comes up.
But my questions is:
At 03:15 a backup job via RMAN is starting.
Looks like that RMAN is responsible for this crash.
But at soon as RMAN recon that oracle is not available, all oracle processes are restarted.
BUT HOW DOES THE RESTART ?
Then the next question.
After the crash, mrp is not restarted by this 'automatic' process.
Could it be, that RMAN sets the database in backup mode - disables mrp - crashes - and the last status was, that mrp was not active ? So the redoApply is starting again ?

Let me guess: You have a RAC standby database but you maintain it without Data Guard Broker. The clusterware on the node (precisely: crsd background process, belonging to the clusterware) where the instance crashed restarts the instance. Because there is no DMON (no Data Guard Broker configured), the MRP is not started automatically. Suggestion: Use also Data Guard Broker.
Kind regards

Some background processes getting killed abruptly

Hi,
We have an E-Biz database and sometimes users complaint that some of the forms/JSP pages are not working fine. When i check the alert log, i find the following error messages which are marked as non critical.

When i checked the background processes, mmon and mmnl processes were not running. When we restarted the database, everything started working fine.
this problems keep coming occasionally. Any help will be appreciated.

Dear muneer.uae,
SHUTDOWN: waiting for logins to complete.&
PMON failed to delete process, see PMON trace fileWell i think those are enough for you to understand the problem but the important thing here to diagnose is the "deadlock". First of all forget about everything and answer the question "do you know what is a deadlock?". If your answer is no, please go to the http://tahiti.oracle.com and search for deadlock.
The problem is not the Oracle database, is the application that you are currently using. You have nothing to do about the suicide of the PMON and if you can not solve it by your own than you need to create an SR call.
Background processes "normally" do not kill theirselves.
Regards.

RAC instance won't start: ORA-00443: background process "VKRM" did not star

I've logged a SR with Oracle, but while waiting for response from them...I'm stumped I can't find more out here about this article.
On Oracle knowledgebase...any search for VKRM, gives about the same 3 articles relating to RDA (Remote Diagnostic Assistant).
Not sure what went on here.
I have a 5 node RAC cluster. All other instances seem to be running just fine.
On one instance...some applications were getting an error like:
ORA-01033: ORACLE initialization or shutdown in progress
I looked in GRID...and it indicated that only two of the 5 nodes had this instance running...which was strange in that with srvctl, it showed ll 5 up and running:
[oracle@server2 bin]$ ./srvctl status database -d INSTANCE
Instance INSTANCE1 is running on node server1
Instance INSTANCE2 is running on node server2
Instance INSTANCE3 is running on node server3
Instance INSTNANCE4 is running on node server4
Instance INSTANCE5 is running on node server5
Anyway, thought I'd poke around. I started with trying to get srvctl to stop instance #2...in GRID it seemed that instance 2,4 and 5 weren't working.
srvctl stop instance -D INSTANCE -i INSTANCE2
This just hung...
I thought I'd cycle all the nodes...so, did a ctl-c out of that one, and did:
[oracle@server2 bin]$ ./srvctl stop database -d INSTANCE -o abort
PRCD-1124 : Failed to stop database INSTANCE and its services

The ORA-01034 messages repeats a number of times...and the one with server4 and server5 repeated again too.
I also got this:

I get similar messages when I try to restart.
clusters seem to be up, and other instances seem to be ok
Looking at alert log...I found some strangeness in the traces

Anyone? Anyone? Bueller?
Ok..have been on phone with Oracle support, and have them stumped so far.
I've checked..other instances are running (except one other that failed to cleanly shut down with srvctl and same error messages).
I've check...ASM is running on all 5 nodes. I've used crsctl to check CRS on all nodes..clustering seems ok.
Memory while somewhat high...should have enough room...the system has never complained before, and this has been up on this config for over a year.
I was able on node one...to fire up the first nodes instance using the pfile there...it came up. I started it restrict..and promptly ran a datapump export, and then shut back down.
While Oracle support is going through logs and trace files I sent...I've got another 11Gr2 environment (3 node RAC) I've been using as a test environment...and am recreated the instance there temporarily to allow my developers to test and get past the upcoming deadline.
But, I'm still puzzled as to the solution on the main cluster. This seem to be normal, except these two instances....
any ideas on where and what to look for?

The request could not be submitted for background processing.

It's an BOE XI SR2, on Win2k3 server, with a print cluster with two print spools, handling 3000+ printers. I discovered this error to be intermittent and only on one of the spools. It turned out that the only common factor was an HP4250 print driver. I backed all the 4250s down to 4200 drivers and the intermitent error ("Error in File. The request could not be submitted for background processing.") went from about 100 a day to zero. The other spool had a different version of the HP4250 driver and would on rare occassion cause this error, "Error in File ... Page header or footer longer than a page." but never the background processing error.
For reference, when I got this error in XI R1, this was the solution for 'the error with one name and many causes':The error "The request could not be submitted for background processing" can be related to a corrupt or wrong versioned crpe32.dll in the Crystal bin folder. Renaming to crpe32.dll_bak and using the repair command in the the "Add/Remove Programs" tool in the "Control Panel" will reinstall the correct dll. Then restart the Crystal services.

For Crystal reports :
Error : "The request could not be submitted for background processing"
I think,this was not related to a corrupt or wrong versioned crpe32.dll.
but the below mentioned is one of the reason for getting this error.
I got the error when the main report(crystalreports10) having more than 2 subreports not assigned proper tables for the subreports.
Example: (this code raise the abone mentioned error.)
rpt.SetDataSource(Exdataset);
rpt.Subreports["subreportname1"].SetDataSource(Exdataset); // Exdatatset.Tables[1]
rpt.Subreports["subreportname2"].SetDataSource(Exdataset);// Exdatatset.Tables[2]

Background process taking very long time to complete.

Dear All,
Platform: HP UX
Version: 12.0.6

Thanks in Advance,
Sandeep.

Sandeep,
Please see (Note: 567551.1 - Configuring various JVM tuning parameters for Oracle E-Business suite 11i and R12).
You can safely kill those processes from the OS.
Thanks,
Hussein
