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.
The environment variables set are the same:
oracle_test> env | grep ORACLE
ORACLE_BASE=/OraBin
ORACLE_SID=uat
ORACLE_TERM=3151
ORACLE_HOME=/OraBin/product/8.1.7
oracle_dev> env | grep ORACLE
ORACLE_BASE=/OraBin
ORACLE_SID=dev
ORACLE_TERM=3151
ORACLE_HOME=/OraBin/product/8.1.7
TWO_TASK variable is not set.

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

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
Bug 3248886 - Continous 'restarting dead background process qmn0' message in alert.log
As a workaround set AQ_TM_PROCESSES=0. Don't do this when Oracle Streams is used.

what is EMN0?

It is the event monitor process related to advanced queuing. See Metalink note 105067.1 about it.

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.

"Unable to connect to background process" HEEEEEEELLLLLLPP!

I just bought a G5 and I transferd all my files from my G4
I'm using Compressor 1 to compress my self contained FCP movies for DVD studio...I got the dreaded "Unable to connect to background process" so I researched and found that I needed to get rid of 3rd Party Utiitys or Disk Utility..I did both and I'm still getting the warning after I re install Compressor???***???
I have spent all day tring to get this to work...and i'm about to throw
my G5 against the wall!!! What the **** am I doing wrong???
One thing I put my Apple Disk Utility in the Trash with out empting
it..Because I Can't figure out how to disable it?? can that be the problem????
I need to figure this out ASAP I have a dead line looming over me ..
My poor G4 is compressing fine ..But it will take 27 Hours to finish..
Please Help..
A frustrated Apple user..

HI
The fix outlined here http://docs.info.apple.com/article.html?artnum=93234 didn't work for me, but here's what did...
I searched QMaster in Spotlight, then right clicked on all the folders and 'revealed in finder'. I then deleted the file/folder and emptied the trash until the only QMaster entry in Spotlight was the System Preference control panel.
I also deleted the compressor pkg in the library receipts folder as mentioned in the Apple link.
Then I repaired permissions and reinstalled Compressor and QMaster from the DVD.
Then I repaired permissions, restarted and did a software update. This updated QMaster for me.
Then I repaired permissions and restarted again.
Now Compressor allows a Batch to be submitted!
Hope this helps someone.

The request could not be submitted for background processing.

Post Author: Chriss
CA Forum: Administration
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 Processing? how schedule job for "System Error" Message .

Hello everyone,
in sap help i have read.
http://help.sap.com/saphelp_nw04/helpdata/en/5a/f72040599a8f5ce10000000a155106/frameset.htm
PCK> Monitoring>Message Monitoring-->Background Processing
you can schedule jobs for various background processing:
●     Archiving of messages processed successfully
●     Deletion of messages that are not to be archived
●     Restarting of messages with errors
●     Rescheduling of lost messages
can anyone understand this docu?
give me some introduction, how can i define and schedule these jobs ?
thx in advance!!
best regards
Yaning

Background Processing
Prerequisites
You have started the message monitor on the initial screen of the PCK and are in Background Processing.
Features
Archiving
You require two archiving sessions to archive messages:
●     One session to write the messages to the archive
●     One session to delete the persisted messages that have been archived
To do this, you schedule an archiving job, which implicitly schedules the sessions to write to the archive and delete the archived messages.
You can define one or more rules for each archiving job; these rules contain conditions that a message must meet in order to be archived by the job. At least one of the defined rules must be met for archiving to take place.
All information that is displayed for a message in message monitoring is archived, in addition to the audit log for each message.
Deleting
A standard delete job is created automatically. It runs once a day. You can schedule additional delete jobs; however, you cannot define rules for them.
Restarting
Instead of restarting messages with errors manually with message monitoring, you can schedule a job to automatically restart these messages. This is possible for all messages for which the number of defined restart attempts has been exceeded (messages with the system error status).
You can define one or more rules for each job to restart messages; these rules contain conditions that a message must meet in order to be restarted by the job. At least one of the defined rules must be met for archiving to take place.
Rescheduling
A standard job to reschedule messages is created automatically. The job runs once a day and ensures that messages lost as a result of database failure, for example, are rescheduled. You can schedule additional rescheduling jobs; however, you cannot define rules for them.
Thx Aamir.
But I mean the messages with errors in Adapter Engine , not in Intergrations Engine.
the situation is like Naveen Pandrangi's WebLog
II. Errors in Adapter Engine [XI : How to Re-Process failed XI Messages Automatically|XI : How to Re-Process failed XI Messages Automatically]
I
Till now we have seen how to resubmit/restart message that failed in Integration Engine. One a message makes it from Integration Engine to Adapter Engine, the message is flagged as checked in Integration Engine. The status of the message in Adapter engine does not effect the processed state in Integration Engine. Now if this message was asynchronous, XI will by default try to restart the message 3 times at intervals of 5 minutes before the status of the message is changed from Waiting to System Error .
*how can i schedule a job to automatically restart these messages with errors?
best regards

Error: The request could not be submitted for background processing

I'm getting an intermittent error in our custom reporting application using Crystal Reports Server XI R2 w/ SP1:
Error in File C:\WINDOWS\TEMP\{F6D30537-956A-458C-96D0-84ECB520D688}.rpt: The request could not be submitted for background processing.
I'm using the Report Application Server XI Release 2 .NET SDK. This is the code that produces the exception (The export type is pdf):
ByteArray ba = this.reportClientDocument.PrintOutputController.Export(ConvertExportReportTypeToCrystalReportExportType(),0);
The error is also logged by Business Objects in the crystalras log file:
ErrorLog 2007 12 3 12:24:56.531 6624 4872 (\servers\ras\dtsagent\reporthandler.cpp:11592): CReportHandler::buildReportViewerError: CSResultException thrown.

The request could not be submitted for background processing." DetailedErrorMsg:""
This has been happening regularly about once a week, at which point the RAS fails and no more reports can be run until the CMS and RAS servers have been restarted.
Has anyone else had this problem, or have any ideas?
Thanks

It was not a bug (not in all cases anyhow), but it is one of those error message that might as well say; something went wrong. I wrote an article on the most likely cases for the error and the article can be downloaded from here;

Postprocessing - background processing - Still running!!!

Hi All
I think I am having a small problem with this task 'Postprocessing - background processing' during the Postprocessing Phase. Basically on previous runs, this task has finished quite quickly however during this next run it is taking hours. I have restarted this phase and it does not seem to finish.
I have checked SM66 to see if anything is running and there is nothing there. All of the other processes have finished successfully, just not sure about this one.
Has anyone had this issue before or can you give me an insight to what it is doing?
Thanks in advance
Phil

"Postprocessing - background processing" is not actually a task, it is there only to group the sub-tasks (from "Transfer of Number Range Intervals" to "Change Logical System Names"). When you execute it, it will run all the sub-tasks (in the Standard View this complexity is hidden, so you don't even see there are sub-tasks).
If the sub-tasks are all Complete then there is nothing left to do. It is normal that there is no State icon for that grouping task, or that Progress is 0. If you execute it again you are running all the sub-tasks once again (you probably received a pop-up to confirm that's what you wanted). In that case, the column "Exec No" in the sub-tasks probably shows that some were executed more than once (some are repeatable and some are not).
Hope this helps,

Could not support request for background processing

Hello,
We have a .NET 1.x application with CrystalReportViewer control.
The application is running on a windows terminal server with approximatively 5 users using the applications and 10-20 logged on doing other stuff.
When the user tries to preview the report using the CrystalReportViewer object , the following exception is "sometimes" thrown
[translated from dutch]
CrystalDecisions.CrystalReports.Engine.InternalException:
error in file C:\Users\*username*\AppData\Local\Temp\35\{B8D10435-A104-4422-A220-6DB483DFC285}.rpt:
The request could not be submitted for background processing. ---> System.Runtime.InteropServices.COMException (0x800002AD)
The application then terminates and if the user restarts the application attempts to reload the report, it usually loads with no problem .
It can not be intentionality reproduced but it does happen frequently.
I have been Googling for this problem , but havn't found any solution.
On this website however a link is provided to a BO KB article with a possible solution:
http://aspadvice.com/blogs/rjdudley/archive/2005/10/26/13443.aspx
However, the article appears to require a login, my SAP CR account i used to register on these forums does not to work.
What can we do to determine the exact cause of this problem, or are there any known solution for this problem ??
If you need any more information please do ask.
also,
We have a licence for CR 11 and so does our client, what steps would we need to undertake to get professional /payed support from SAP crystal reports for techinal issues like this, is there a way to open a support ticket ?
Thank you very much for your time, any help is appreciated !
Willem

Hello:
First I have to apologize for the troubles with CR 11.5 - not sure why that would be, but your frustration is understood. Perhaps sometime in the future we can look at this in another thread (e.g.; it should just work...).
Anyhow, there is really no compeling reason for you to go to CR 11.5 (there are reasons (see below), but 11.0 is fine with framework 1.1).
So to start off. Version 11.0.0.895 will need to be updated to SP4. See this|http://wiki.sdn.sap.com/wiki/display/BOBJ/CrystalReports2008%28and9.1%2CXIR1%2CXIR2%29-VersionandDownloadinformationforServicePacks] wiki. As you can see in the wiki, the latest version of CR 11.0 is updated to SP 4 with a version of 11.0.9500.x. Before we even start to look at this, you will have to get to SP4.
Re. preference for CR 11.5. If the issue is not resolved with CR 11 Service Packed to SP 4, all we have left is; going to CR 11.5 - with the latest SP (SP6) as that is the version I would be testing with. Note that CR 11 is completely out of support now, CR 11.5 is out of patch support (e.g.; no fixes) and any support terminates in June of this year.
And we have not even started to work the issue. Re-reading your initial post, I am starting to suspect that loading may be the root of the issue here. I'd recommend having a peek at the following:
http://www.sdn.sap.com/irj/boc/go/portal/prtroot/docs/library/uuid/d08468e2-a81d-2b10-faa9-9837f58ee1c2
http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/7025839b-00d4-2b10-33b4-cf0aa9e08412
The following article specifies CR 2008, but most if not all the points will apply to CR 11.0 also:
http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/7025839b-00d4-2b10-33b4-cf0aa9e08412
The below will also be good to be aware of:
http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/40bccdfd-88a6-2b10-1da1-c47a54b625a7

The following articles were written by me and may also apply:
[Crystal Reports Maximum Report Processing Jobs Limit|http://www.sdn.sap.com/irj/boc/index?rid=/library/uuid/f053713e-3e3d-2c10-2a81-f79259e54023]

I realize I've thrown a lot of info in here, but all of it may apply. In a way I feel like we've ended up across the river without crossing the bridge first, but let's see what comes out of all of this (teleporting worked for Captain Kirk ).

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.
Thu Oct 21 06:42:41 2010
Non critical error ORA-48913 caught while writing to trace file "/db1/ora1211/db/tech_st/11.1.0/admin/RGDB_orargpdb/diag/rdbms/rgdb/RGDB/trace/RGDB_ora_23488

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
PRCR-1065 : Failed to stop resource (((((NAME STARTS_WITH ora.instance.) && (NAME ENDS_WITH .svc)) && (TYPE == ora.service.type)) && ((STATE != OFFLINE) || (TARGET != OFFLINE))) || (((NAME == ora.instance.db) && (TYPE == ora.database.type)) && (STATE != OFFLINE)))

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

CRS-2675: Stop of 'ora.instance.db' on 'server5' failed
CRS-2675: Stop of 'ora.instance.db' on 'server4' failed

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?

Disk utility started, but a background process needed in disk utility didn'

I am stumped. I have talked to tech support, read many threads on this error message, tried all the suggested solutions, and still I get this message "Disk utility started, but a background process needed in disk utility didn't start properly. Please quit and restart disk utility."
The problem has been around for a while apparently. One technique called for removing iTunes to the desktop, trashing certain files in the library, then running disk utility. This did not work. Another suggestion was to trash, of all thing, the Chess program. This also did not work. Booting from the installation disk and running disk utility there to repair permissions also apparently does not work. Nor do third party software, such as YASU seem to get through to repair permissions.
Given the number of discussion boards addressing this problem, i was stunned that applecare/tech support person I talked to had never heard of it. Please please please help!

If you moved Disk Utility from the /Applications/Utilities directory, i.e. the Macintosh HD > Applications > Utilities folder, move it back to that folder.
If memory serves, the "workaround" you cited involving iTunes only applies if you are using Mac OS X 10.3.9.
Good luck!
