ORA-30678: too many open connections with UTL_MAIL.send
I'm have just recently started getting the ORA-30678: too many open connections error while calling the UTL_MAIL.send procedure to send emails via a pl/sql package. The call is made within a loop and there can be a significant number of calls made to this procedure. In fact, I received this error over 1400 times within the last three days. This was previously working until I made a change to the processing which now results in a larger number of emails/calls to this procedure. I don't see any documentation on how (or if) I can close the connection with UTL_MAIL.
I'm using Oracle 11g. Any insight would be much appreciated.
Thanks,
Teri
Looks like a bug possibly, check out this MOS Note:
Ora-30678: Too Many Open Connections From UTL_MAIL [ID 788442.1]
The bug note says it was fixed in 11.2. Not sure which version of 11 you are running.

UTL_MAIL --- ORA-30678: too many open connections
Hello,
I have a pl/sql package that sends out emails using UTL_MAIL pkg pointing to an Exchange server, an APEX app calls this pkg.. This package used to work fine for months but I recently noticed that some emails are not being sent as expected. The package loops through a set of action items satisfying some conditions and send emails based on that ( this number is expected to grow every day ). I checked the errors log and I found this error:
ORA-30678: too many open connections
I think this means that I have to close the connection everytime I send en email, but UTL_MAIL does NOT have a function or a proc to close connections, right ?
I don't know what causes this error to happen, but I suspect that this started happening right after we re-pointed the UTL_MAIL pkg from a Lotus Notes server to an Exchange server.
I am also seeing this error:
ORA-29279: SMTP permanent error: 501 5.1.3 Invalid address
I know where this error comes from (usually a null email id in the FROM or TO field ), but can this be causing the first error to happen ?
Please advise if you got this error before, is it a bug in oracle 10g as I read in some blog ? or is the second error happening make the Exchange server refuse SMTP connections ???
Thanks,
SamHi Sam,
seems to be a bug in UTL_MAIL if you ask me, as you are right - there is only /send/, no option to close, so I'd expect this to be done automatically.
Anyway, though UTL_MAIL is usable for basic mailing, I prefer using a custom mail implementation based on UTL_SMTP. The most important reason is that most mail servers don't work without authentication. And if you have done this once, you can reuse the function/procedure/package as simple as UTL_MAIL. The good news is, that there are several examples published that provide you with the functionality you have in UTL_MAIL at once - with the difference, that you definetly get your connection closed when you expect it to be closed.
You'll also be able to handle empty addresses. Perhaps this error actually causes UTL_MAIL to "forget" to close the connection, if this exception isn't caught before in order to close an open connection before raising it to the outside.
One example implementation for using UTL_SMTP can be found [url http://www.morganslibrary.com/reference/pkgs/utl_smtp.html]here

Below is the username I keyed in the email_setting table, with reference to the select username statement from the procedure as above.
username in email_setting => [email protected]
I also tried key in as '[email protected]' but still not working.
Could someone suggest any solution? Thanks..Mr. Saubhik,
Yes, no data passed for the From: as shown from the dbms output error message shown below:

ORA-29270: too many open HTTP requests
Hi,
We have a requirement like, we will get bulk data (2 GB) data file with different languages(Russian, chinese, Japanese, German) etc. and we need to load these data into our databse also we have to translate the same.
We are using Oracle 11g.
We had used Oracle httpuritype - And the below mentioned procedure PROCEDURE TEST.PRC_TRANS_GERMAN will call the function - trans_jef
Input parameter for PRC_TRANS_GERMAN - > To_language and from Language. and this procedure will store the translated word in the seperate table.
Input parameter for the function trans_jef - > Word to be translated , from languae, to_language. And this function will return the translated word.
The issue I am facing is when I am passing the table of around 10000 records, around 4000 rows are not getting translated. So when i try to capture the error in exception- the error is
ORA-29273: HTTP request failed
ORA-06512: at "SYS.UTL_HTTP", line 1819
ORA-29270: too many open HTTP requests
When I try to re execute the missed words, they were translated. But they are not getting translated in one go because of the too many http open request.
So could you please let me know how to resolve this ORA-29270 errror. I know we have to end the request and start again. But not sure how to do. Can some one help with this~!!!!

Use camelcase and pascalcase for variable names and procedures/functions/methods. Restrict the use of uppercase to defining identifiers such as compiler macros or constants.
Do yourself a favour and read, understand and apply the basic naming standards as detailed in .Net Guidelines for Names and Code Conventions for the Java Programming Language. -

Is there a way in here to auto close inactive connections after say 10 seconds? Is that the removeAbandonedTimeout or the Eviction section? Would this be better off posted on the tomcat user listing?
Edited by: TheWhiteKnight on Oct 29, 2009 8:00 PMActually BalusC, I like this. This seems to define the entire cycle quite nicely and CLEAN. This will be very helpful when phase II rolls out. Right now I need to just patch the thing and get it running "well".
I've also had to implement some new methods to clean up some of the junk that is left open. I have found RS's that are closed, but no corresponding connection / statement's are being closed. So when I have a return statement like:
return ConnectionPool.getConnection().createStatement().executeQuery(sqlStatement);
{code]
that is called from the presentation layer, logically (to me) the only place to close the connection / statement associated with that RS is in the presentation layer. As of right now. This will change on phase II. If I am wrong please correct me in this.
Something that is happening now though since I have started explicitly closing the connections and statements. It seems that my ConnectionPool is running out of connections. I can increase the size of the pool, but it worked just fine before with the amount of connections I have set. When I call .close() on the connection, does that "recycle" the connection back to the pool? I know there has to be resources bleeding someplace, however, this has only started happening (more often) since I have been closing things where I find them.
Any ideas on this?
Also will converting the basic generic queries to stored procedures help in the performance? I know that I'll still have to have a connection, but if I can have less java coded sql statements and more SP's would that help in efficiency between MySQL and Tomcat? -

The error code the caller executing this code receive is -01403. A unique error number that has a known and specific meaning.
In addition, the error stack tells the caller that this unique error occurred on line 2 in the source code.
The caller knows EXACTLY what the error is and where it occurred.

9 /
begin
ERROR at line 1:
ORA-20000: oh damn some error happened. the error is ORA-01403: no data found
ORA-06512: at line 4
In this case the caller gets the error code -20000. It is meaningless as the same error code will be use for ALL errors (when OTHERS). So the caller will never know what the actual real error is.
For the caller to try and figure that out, it will need to parse and process the error message text to look for the real error code. A very silly thing to do.
In addition, the error stack says that the error was caused by line 4 in the code called.. except that this is the line that raised the meaningless generic error and not the actual line causing the error.
There are 3 basic reasons for writing an exception handler:
- the exception is not an error
- the exception is a system exception (e.g. no data found) and needs to be turned into meaningful application exceptions (e.g. invoice not found, customer not found, zip code not found, etc)
- the exception handler is used as a try..finally resource protection block (which means it re-raises the exception)
If your exception handler cannot tick one of these three reasons for existing, you need to ask yourself why you are writing that handler. -
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.
TomThanks 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

Hello all,
I have a view called V_MEDGEN_LISTRADIO but I can't run

Operation Could Not Be Completed: Too Many Open...
I've had this error showing up a lot in the Safari 3.2 and 4.0 beta activity window when loading multiple tabs of pages with many images (usually gallery type pages or blogs with lots of thumbnails). The result is that some images or other elements like style sheets don't load, leading to the blue question mark, or messed up formatting. Unfortunately, the activity window can't be stretched wide enough to see the whole error, but in fact it's "Operation Could Not Be Completed: Too Many Open Files". The error "socket(PF_ROUTE) failed: Too many open files" shows up in the Console as well, at least with Safari 4. I had also experienced similar problems with "Operation Timed Out" errors as well.
I've been pulling my hair out on this one, because it's rather inconsistent, not to mention annoying. You can usually get an individual page to load completely by refreshing it, but that kind of defeats the purpose of loading multiple tabs all at once. It's also less of a problem if more of those pages are already cached, but you never know for sure. Running your connection through a proxy also helps a bit, but not always.
I found a fix, but it's actually not Safari's "fault" per se. The issue lies in the allowable number of open files per user process, which is set by the system's launchd process at boot time. Note that Safari is not entirely innocent, as FireFox doesn't have this problem. It Seems that Safari just tries to load everything all at once, whereas FireFox does a better job of managing its load requests. Anyway if you run the following command in Terminal:
sudo launchctl limit
the following list should show up (with perhaps slightly different values)
cpu unlimited unlimited
filesize unlimited unlimited
data 6291456 unlimited
stack 8388608 67104768
core 0 unlimited
rss unlimited unlimited
memlock unlimited unlimited
maxproc 200 532
maxfiles 256 unlimited
The second column is a "soft limit" and the third column is a "hard limit", though to be honest I'm not exactly sure what the difference entails. The image loading problem is caused by hitting the maxfiles limit of just 256 files. The solution is to change maxfiles to 4096/unlimited, and also change maxproc to 1000/2000 since it's pretty low as well. That sounds like a pretty big change, but OS X server is supposed to change them to numbers like this when services like Apache are enabled, and Apple even mentions how to change maxproc at http://support.apple.com/kb/TS1659
To make these changes, run the following two commands in Terminal and restart the computer:
echo "limit maxproc 1000 2000" | sudo tee -a /etc/launchd.conf
echo "limit maxfiles 4096 unlimited" | sudo tee -a /etc/launchd.conf
The commands add the two lines in quotes to the launchd.conf file in /etc/ (if no file exists yet, it creates it). That should clear up the loading issues. I haven't noticed any other problems with these increased numbers, but I'll report back if anything seems to go amiss. Hopefully this will be helpful to someone.I faced the same problem with an image gallery using css for image resizing. Thanks for the explanation.

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

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

Java.util.zip.ZipException: Too many open files on Linux
Hi,
We have web application running on Caucho's resin server on jdk 1.5.0_11 and Red hat Linux. We are noticing that java process is running out of file handles within 24-30 hours. We have file limit of 5000 which it consumes in 24 hours throwing 'java.util.zip.ZipException: Too many open files'.
I have made sure all sorts of file handles are closed from application point of view. Here is the snapshot of lsof (list of file handles) from java process. The following list keeps growing until it runs out of limit. Do you have tips/suggestions on how to mitigate this problem (considering we dont want to increase ulimit for this process)? Also, can you make out any thing more from the description of file handles like, are they unclosed POP3 connections or URL connection to external sites?

It was oracle driver which had some compatibility issue, we upgraded our Oracle client driver to newer version, and this fixed the problem. Base line, there was nothing wrong with application code, code was doing good resource clean up, but oracle driver was leaking handles per every connection.

Too many authenticated connections
I've got a customer with a BT line, sending via mail.btinternet.com. For the last month or two they've complained that they keep getting asked for their password.
I've checked out the customer's system and I can see that it's not a password problem, but the SMTP server is instead coming back with "too many authenticated connections".
I can see that a host of BT customers on here are reporting password problems, I would guess that they are experiencing the same issue, that these are not password problems, but SMTP server issues on BT's new mail systems. The message would suggest that the server is unable to take any more connections so some sort of resource issue at their end.
Of-course unless you're looking under the bonnet of the SMTP connection, you won't be seeing this message, just the popup asking for your password again. It's not a password issue. If you try the connection multiple times, it will go in the end (when you get a connection that is willing to be accepted by the SMTP server.
I've configured the mail client to the letter, as per BT's stated configuration, and like I say, it will work on a percentage of connections. On a good run, you might get 10 out of 10 successes, other times 1 in 3.
Please let me know if anyone is experiencing the same message. The message could perhaps be a red-herring of some kind, perhaps not able to successfully negotiate the authentication / encryption using this particular mail client. The customer is using Mac Mail and there do appear to be quite a few customers referencing Mac's / IOS on this forum, not many Outlook customers complaining.Hi Bookanengineer,
Many thanks for your post, we have been away and asked some questions around this and the view is that this is unlikely to be an SMTP load issue. There is a limit to the number of authenticated connections we allow per user and the password pop ups being seen are more likely to be due to the customer having too many authenticated connections which could also be due to sessions not being closed correctly
We believe that this is more likely to happen to client users as each time your client connects it opens an authenticated session. If, when you disconnect, the session does not close for whatever reason, the mail server still shows you with a session open. If that happens often you will quickly hit the limit for the number of sessions allowed per customer
We do however need to eliminate other issues so need examples to further investigate, I appreciate that you are speaking on behalf of one of your customers, but if you are able to send in any details to us so we can take a look that would be great. You can send in the details using the "Contact The Mods" link found in my profile.

ORA-02020 too many database links
Hello,
I'm getting the ORA-02020 too many database links error in my Apex application. This error occurs when I run an interactive report in a page. There are 21 pages and 7 database links in the application. Each page has one interactive report that references one database link in the region source.
The database links are referenced in each page as follows: database link1 (page 1); database link2 (pages 2 and 3); database link3 (pages 4-7), database link4 (pages 8-15); database link5 (pages 16-18); database link6 (pages 19); and database link7 (pages 20-21). Each database link is referenced to separate schemas in one remote Oracle database.
I tried to eliminate the error by setting the open_links and open_links_per_instance parameters in the init.ora file of the remote and XE databases to 100 then restarted the both databases. This solution did not work. I created separate Application Processes from the Shared Components to close each database link by implementing the following:
Click on Shared Components> Logic > Application Processes > Create >
Name: CLOSE_LINK1
Sequence: 1
Point: On Load: Before Header (page template header)
Type: PL/SQL Anonymous Block
Process Text: execute immediate 'ALTER SESSION CLOSE DATABASE LINK LINK1';
Error Message: Database Link Error
When I run the application now, the ORA-02081: database link is not open error appears.
Please help anyone! I know someone has experienced these same errors.
Thanks,
Ms. HJoel,
Thank you for your quick response. For clarification purposes, could you provide samples for 1) issuing the CLOSE DATABASE LINK and catching the exception; and 2) querying from V$DBLINK prior to issuing the CLOSE DATABASE LINK from the Shared Components > Logic > Application Processes?
Lets assume the following query with a database link in the region source is referenced for Page 1.
Page 1 - Employee Listing
Region Source:
select ename, job, hiredate
from scott.emp@link1
Lets assume the following Application Processes from the Shared Components is referenced to close the database link:
Click on Shared Components> Logic > Application Processes > Create >
Name: CLOSE_LINK1
Sequence: 1
Point: On Load: Before Header (page template header)
Type: PL/SQL Anonymous Block
Process Text: execute immediate 'ALTER SESSION CLOSE DATABASE LINK LINK1';
Error Message: Database Link Error
My thoughts are to do the following:
1. Log in SQL*Plus as SYS
SQL> grant select to v_$dblink to scott;
2. In Apex, goto Shared Components> Logic > Application Processes and add the following queries in the Process Text:
Name: CLOSE_LINK1
Sequence: 1
Process Text:
select db_link from v$dblink;
execute immediate 'ALTER SESSION CLOSE DATABASE LINK LINK1';
3. Catch the exception???
Your assistance is greatly appreciated. :8}
