Too many trace files apparently created on behalf of Health Monitor

Every ~10 minutes I see two pairs of trc+trm files that appear to be nothing more than a nuisance. A nuisance because if you don't get rid of them, then commands such as "ls -lt | head" take too long to complete. Even after setting disablehealth_check=true, the files still keep coming. The only thing I can find is a correspondence between the rows in v$hm_run and these trace files.
The RDBMS appears to be working fine and there's nothing in the alert log that would explain their existence. Having said that, I'll go ahead and admit that I don't these are false negatives but it sure looks like they are.
Below is a sample of the two trace files in the 4 files that get created every 10 minutes. Thanks.

The corresponding data from v$hm_run (and the view definition itself) show that status = 5 means 'COMPLETED'. The interesting thing is that RUN_MODE.RUN_MODE is 'REACTIVE'. This seems to say that it's not a proactive thing. But if something is reacting, then why is it showing no error (i.e., ERR_NUMBER = 0)?

Too many trace files generated by program ORACLE.EXE (J001) in "bdump"

No version number and not enough information in what you posted to help you.
Did this just start?
If so what actions preceded it?
Or is this a new install?
Have you tried bouncing the instance?
If it were my system I would have already searched the knowledgebase at metalink and opened an SR if I couldn't find a solution. Did you?

Too many trace files 11g

Thanks for taking my question!
I just installed 11g and I have a ton of .trc and .trm files. A trc file and trm file is created for just about everything - even Rman backups. I prefer these jobs to show in the alert log not independent trc files.
Has anyone experienced this issue with 11g? Is there a way to stop the trace files from taking over:)
Thanks, Kahtie

There's no way to stop,but to maintain ADR (Automatic Diagnostic Repository) :

"java.io.IOException: Too many open files" in LinuX

Hi Developers,
* I am continiously running and processing more than 2000 XML files by using SAX and DOM.....
* My process is as follows,
- Converting the XML file as Document object by DOM....
- And that DOM will be used while creating log file report, that log file will be created after executing all XML files..
* After processing approx 1000 files, it throws *"java.io.IOException: Too many open files" in LinuX system* ....
* I have googled more and more in all sites including sun forum also, but they are telling only to increase the system config by ULIMIT in linux....If i increase that its executing well without exception........
* My question is, Is it possible to do it by JAVA code itself or any other VM arguments like -Xms512m and -Xmx512m.....
* Please let me know , if you have any idea.....
Thanks And Regards,

Intermittent too many open files error and Invalid TLV error

Post Author: jam2008
CA Forum: General
I'm writing this up in the hopes of saving someone else a couple of days of hair-pulling...
Environment: Crystal Reports XI Enterprise / also runtime via Accpac ERP 5.4
Invalid TLV error in Accpac
"too many open files" error in event.log file
Situation:
Invalid TLV error occurs seemingly randomly on report created in CR Professional 11. Several days of troubleshooting finally lead to the following diagnosis:
This error occurs in a report that contains MORE THAN 1 bitmap image.
The error only shows up after 20 or more reports have been generated sequentially, WITHOUT CLOSING the application that is calling the report. In our case the Invoice Report dialog within Accpac. This same error occurred in a custom 3rd party VB.NET app that also called the report through an Accpac API.

after getting this message you need to do 2 things:
1. delete the current workspace because it contains some bad data in one the config files - failure to delete the workspace will result the error message to appear even if trying to upload a single file.
2. add to DTR files in groups - no more than 500 in a single add.

Actually, the stuff works in interpreted mode.
It's only when having the server partition compiled that this happen.

Hi Jean-Paul,
As described in the Technote 10981 some Forte programs (Nodemanager and

that Forte interpreter do it correct too.

sudo sysctl -w kern.maxfiles=32768
sudo sysctl -w kern.maxprocperuid=16384
seemed to work.
Created file /etc/sysctl.conf containing:
kern.maxfiles=32768
kern.maxprocperuid=16384
so that the setting would survive a reboot.
Hopefully that permanently fixes it.

What have "Too many open Files" to do with FIFOs?

Hi folks.
I've just finished a middleware service for my company, that receives files via a TCP/IP connection and stores them into some cache-directory. An external program gets called, consumes the files from the cache directory and puts a result-file there, which itself gets sent back to the client over TCP/IP.
After that's done, the cache file (and everything leftover) gets deleted.
The middleware-server is multithreaded and creates a new thread for each request connection.
These threads are supposed to die when the request is done.
All works fine, cache files get deleted, threads die when they should, the files get consumed by the external program as expected and so on.
BUT (there's always a butt;) to migrate from an older solution, the old data gets fed into the new system, creating about 5 to 8 requests a second.
After a time of about 20-30 minutes, the service drops out with "IOException: Too many open files" on the very line where the external program gets called.
I sweeped through my code, seeking to close even the most unlikely stream, that gets opened (even the outputstreams of the external process ;) but the problem stays.
Things I thought about:
- It's the external program: unlikely since the lsof-command (shows the "list of open files" on Linux) says that the open files belong to java processes. Having a closer look at the list, I see a large amount of "FIFO" entries that gets bigger, plus an (almost) constant amount of "normal" open file handles.
So perhaps the handles get opened (and not closed) somehwere else and the external program is just the drop that makes the cask flood over.
- Must be a file handle that's not closed: I find only the "FIFO" entries to grow. Yet I don't really know what that means. I just think it's something different than a "normal" file handle, but maybe I'm wrong.
- Must be a socket connection that's not closed: at least the client that sends requests to the middleware service closes the connection properly, and I am, well, quite sure that my code does it as well, but who knows? How can I be sure?
That was a long description, most of which will be skipped by you. To boil it down to some questions:
1.) What do the "FIFO" entries of the lsof-command under Linux really mean ?
2.) How can I make damn sure that every socket, stream, filehandle etc. pp. is closed when the worker thread dies?
Answers will be thanked a lot.
Tom

Thanks for the quick replies.
@BIJ001:
ls -l /proc/<PID>/fdGives the same information as lsof does, namely a slowly but steadily growing amount of pipes
fuserDoesn't output anything at all
Do you make exec calls? Are you really sure stdout and stderr are consumed/closed?Well, the external program is called by
Process p = Runtime.getRuntime().exec(commandLine);and the stdout and stderr are consumed by two classes that subclass Thread (named showOutput) that do nothing but prepending the corresponding outputs with "OUT:" and "ERR" and putting them into a log.
Are they closed? I hope so: I call the showOutput's halt method, that should eventually close the handles.
@sjasja:
Sounds like a pipe.Thought so, too ;)
Do you have the waitFor() in there?Mentioning the waitFor():
my code looks more like:
try {
     p = Runtime.getRuntime.exec(...);
     outshow = new showOutput(p.getInputStream(), "OUT").start;
     errshow = new showOutput(p.getErrorStream(), "ERR").start;
     p.waitFor();
} catch (InterruptedException e) {
     //can't wait for process?
     //better go to sleep some.
     log.info("Can't wait for process! Going to sleep 10sec.");
     try{ Thread.sleep(10000); } catch (InterruptedException ignoreMe) {}
} finally {
     if (outShow!=null) outShow.halt();
     if (errShow!=null) errShow.halt();
/**within the class showOutput:*/
/**This method gets called by showOutput's halt:*/
public void notifyOfHalt() {
     log.debug("Registered a notification to halt");
     try {
          myReader.close(); //is initialized to read from the given InputStream
     } catch (IOException ignoreMe) {}
}Seems as if the both of you are quite sure that the pipes are actually created by the exec command and not closed afterwards.
Would you deem it unlikely that most of the handles are opened somewhere else and the exec command is just the final one that crashes the prog?
That's what I thought.
Thanks for your time

hi all,
I am getting a strange error while deploying any composite .. it's a hello world kinda composite but while i am trying to deploy it i am getting "java.io.IOException: Too many open files" while deployment.. i have tried to deploy it in 2-3 ways but all of them resulted in the same error..bouncing the soa server might be an option but can someone give an insight as why it is happening and can it be resolved without restarting the server..
Thanks

But this problem is understandable, as the database is not running. The main problem why database is not running, I have found the reason but do not understand how to solve the problem.
Since, the database was not running, I tried to startup the database, I then came across the following which is my problem (Why so many files are open? Linux OS error says too many files open. See below,
SQL> conn /as sysdba
Connected to an idle instance.
SQL> startup
ORACLE instance started.

Can anybody has run into such problem and guide me to a solution, please?
Thanks

Hi,
yes, this DB was functioning o.k. this configuration script was part of RMAN daily backup.
Last night the backup failed. So, when I opened "Failed job" in the EM, I saw this type of messages.
That was the starting point. Gradually, I tried to narrow down on to the actual problem and found the findings as I have posted.
One way of sovling problem, I thought that, all these processes I would kill and then try to open the database, it might startup. However, that wouldnot lead me in ensuring this won't occur again.
That's why I am trying to understand why it should open, so many processes (why spawn so many .flb files?) Any thoughts you have around this?
I will try to restart the OS as the last resort.
Thanks for your help and suggestions.
Regards,

WLS 10.3.5 on RHEL 5.4, SocketException: Too many open files

Hi
I'm running Weblogic server 10.3.5 on Red Hat Enterprise Linux Server release 5.4 (Tikanga), with Java jdk1.6.0_27.
My order handling application, when receiving client orders, needs to make outbound SOAP calls to fulfill the order. During a performance test, we got following errors:
####<Feb 10, 2012 2:28:41 PM ICT> <Critical> <Server> <KKMOMAPP2> <KKMOMPE2> <DynamicListenThread[Default]> <<WLS Kernel>> <> <> <1328858921806> <BEA-002616> <Failed to listen on channel "Default" on 172.24.106.81:4095, failure count: 1, failing for 0 seconds, java.net.SocketException: Too many open files>
I monitored the java process of this application, when the "Too many open files" error happened, it had 1388 open file descriptors, among which 655 were sockets.
I also monitored the total open file descriptors of the weblogic user account, the count was around 6300 during this error.
These numbers are far smaller than the file limits configured on OS:
- Under weblogic account, ulimit -n shows 65536
- /proc/sys/fs/file-max shows 772591
- Following lines are already in /etc/security/limits.conf
weblogic soft nofile 65536
weblogic hard nofile 65536
weblogic soft nproc 16384
weblogic hard nproc 16384
I did another test using a simple java program to open large number of sockets under weblogic account. It has no problem to open 15,000 sockets. It seems the file descriptor limit is indeed quite high, but for some reasons, the Weblogic process fails even when it has merely 1388 open files. Are there other Linux or Weblogic parameters I should tune? Or anything else I missed?
Thank you very much
Ning
