Too many database connections and configurator logins ?

Hi,
We're having some performance and/or stability problem with Oracle Waveset 8.1.1. patch 2.
I'm not sure what the problems is yet, but two facts got my attention:
I noticed for too many database connections waiting to be closed on the OS, varying between 600 and 1200 :
TCP: IPv4
Local Address Remote Address Swind Send-Q Rwind Recv-Q State
doesburg.ic.uva.nl.33555 hopewell.ic.uva.nl.1539 49640 0 49640 0 TIME_WAIT
doesburg.ic.uva.nl.33556 hopewell.ic.uva.nl.1539 49640 0 49640 0 TIME_WAIT
doesburg.ic.uva.nl.33557 hopewell.ic.uva.nl.1539 49640 0 49640 0 TIME_WAIT
doesburg.ic.uva.nl.33558 hopewell.ic.uva.nl.1539 49640 0 49640 0 TIME_WAIT
etc.
(doesburg is our Solaris 10 server where the tomcat application server is installed, hopewell is our Oracle 10g database server )
I also noticed numerous Configurator logins in the audit log, about 10 per second:
Audit Event Details

Configurator logins on the BPE interface which we don't use?
Has anyone seen something like this before? What could cause it?

I'm still struggling with this problem. Our database administrator did add some tracing, and we see these type of queries:
SELECT tstamp, id, version, changeType FROM objchange WHERE tstamp > :1 AND type=:2 ORDER BY tstamp
SELECT tstamp, id, version, changeType FROM objchange WHERE tstamp > :1 AND type=:2 ORDER BY tstamp
SELECT task.id, task.type, name, :"SYS_B_0", :"SYS_B_1", summary, :"SYS_B_2", :"SYS_B_3", xmlSize, :"SYS_B_4"
SELECT tstamp, id, version, changeType FROM objchange WHERE tstamp > :1 AND type=:2 ORDER BY tstamp
SELECT object.id, object.type, name FROM object WHERE object.type=:"SYS_B_0"
SELECT tstamp, id, version, changeType FROM orgchange WHERE tstamp > :1 AND type=:2 ORDER BY tstamp
SELECT tstamp, id, version, changeType FROM objchange WHERE tstamp > :1 AND type=:2 ORDER BY tstamp
SELECT tstamp, id, version, changeType FROM objchange WHERE tstamp > :1 AND type=:2 ORDER BY tstamp
SELECT tstamp, id, version, changeType FROM objchange WHERE tstamp > :1 AND type=:2 ORDER BY tstamp
SELECT tstamp, id, version, changeType FROM objchange WHERE tstamp > :1 AND type=:2 ORDER BY tstamp
SELECT tstamp, id, version, changeType FROM objchange WHERE tstamp > :1 AND type=:2 ORDER BY tstamp
SELECT tstamp, id, version, changeType FROM rolechange WHERE tstamp > :1 AND type=:2 ORDER BY tstamp
SELECT tstamp, id, version, changeType FROM objchange WHERE tstamp > :1 AND type=:2 ORDER BY tstamp
541 seperate logon sessions by waveset in about 2 minutes.
Has anyone seen this? What could cause it?

Too many database connections?

I have a function that gets called repeatedly from inside a loop. The function opens a connection to the database(DriverManager.getConnection) when it is first called, and closes the connection to the database upon completetion. In addition to this, I have several "permanent" connections while the program is running. My question is, how expensive is making these connections? How many connections are too many?
Thanks,
cmp2

(1) Define a class (Say) MyConnection (like):
package general ;
import java.lang.* ;
import java.util.* ;
import java.sql.* ;
public class MyConnection
public boolean connected = false ;
public String user = "" ;
public String password = "" ;
public String URL = "" ;
public Connection theConnection;
public MyConnection() {
public void getConnection(
String parmUser,
String parmPass,
String parmConnection ) {
boolean connDriver = false ;
String connectionDriver = "oracle.jdbc.driver.OracleDriver" ;
String URLfrount = "jdbc:oracle:thin:@" ;
try {
// Make the Connection
Class.forName(connectionDriver);
connDriver = true ;
} catch ( ClassNotFoundException e ) {
messages.add( "Signon Driver ClassNotFoundException: " + e );
if ( connDriver ) {
try {
URL = URLfrount + parmConnection ;
theConnection = DriverManager.getConnection(URL, parmUser, parmPass);
theConnection.setAutoCommit( false ) ;
connected = true ;
user = parmUser.toUpperCase() ;
password = parmPass ;
} catch (SQLException e) {
messages.add( "Signon Error: " + e );
(2) pass this connection from class to class

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.

Help needed : javamail Too many simultaneous connections

Hello
i'm using javamail to develop a webmail
i've created a service Class , and all things works well , but i have a serious problem when i browse my webmail ( viewing folders: inbox / spam / etc or messages) i get an error saying :
Too many simultaneous connections. (Failure)
i know that the imap server dosen't support more than 10 simultaneous connections.
But i can't say to users using my webmail to do not a lot of actions !!! , and also when i use thunderbird for example it works fine without errors even if i do a lot of actions/connections
How can i solve that problem ?
Thanks

Thunderbird supports disconnected or offline operation. It can disconnect from the server and then reconnect later
and synchronize its state, so that you never know it was disconnected.
You can do that too, but it's a lot of work.
For webmail, the simplest approach is usually to have only one folder open at a time for each user.
If your IMAP server is limiting you to 10 connections total, across all users, get a new IMAP server.

Just upgraded and iPhoto said it has to upgrade library but keeps freezing. Have tried it too many times now and I need those photos ASAP HELP!!

Just upgraded and iPhoto said it has to upgrade library but keeps freezing. Have tried it too many times now and I need those photos ASAP HELP!!

Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Rebuild iPhoto Library Database from automatic backup.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one. .

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,
Sam

Hi 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

ORA-02020: too many database links in use ; but OK with where clause...

Hello all,
I have a view called V_MEDGEN_LISTRADIO but I can't run
SELECT * FROM V_MEDGEN_LISTRADIO
ORA-02020: too many database links in useThe cause is that we call in the view 5 tables over dblink and the open_links parameter is set to 4.
What is strange is that when I run this select by adding a where clause then it works!
SELECT * FROM V_MEDGEN_LISTRADIO WHERE SPRR = 3645;Can someone explain me ? (use of index so all tables are not called ???)
Thanks

Explain plan for SELECT * FROM V_MEDGEN_LISTRADIO WHERE SPRR = 3645;

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. H

Joel,
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}

SMTP Send Mail - too many authenticated connection...

Using Outlook on a MAC, and within this last week I have started to get this error when sending mail. I have read all the forum posts and help documents on this issue and ensured that my settings are as described and yet I am still having this problem.
Should I be switching to IMAP to avoid this problem, and if so how do I do that without losing all my SMTP downloaded email?
Thanks for any insight - it is causing me real issues now as I'm job hunting and can't reply to job emails!!!!

Yes same problem for me. In the last three days, or so, I will get the random "too many authenticated connections" message. I have just phoned BT twice this afternoon and had great trouble understanding both Indian guys. One suggested he's fixed it by adjusting things at BT to accept "S Client Mail", whatever that means! That however didn't fix it. The second suggested I needed to reset password (easy option that one), until I pointed out that I am having no trouble with password use on the BT webmail page or through my phone. He then said I'd have to reload Outlook to solve the problem. Yeah right, like I'm gonna loose all my emails, settings and calendar to satisfy his theory of "if it doesn't work then reload it". There is clearly a server problem somewhere and OH, how I would love to speak to someone, (anyone), at BT who actually knows what they are talking about from a network/server angle. Anyone worth their salary in networks could trace my activity online and find out what was going on and why it was failing.
Setting POP3 and all others checked by BT as being correct.

OK now that there is no option to reveal "database" panel in DW CC, how do I create a database connection and build my phpmysql pages?

Is there an alternative way other than manually entering PHP code?

Thanks, It works. Author of the article politely says what many of us have to say to Adobe when they make "improvements" - WTF, Adobe???

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.

Hi monic,
I'm sorry to hear you are having mail issues on your Mac. I'm a bit unclear exactly which version of OS X you are currently using, but if you continue to have issues sending or receiving emails, you may find the troubleshooting steps outlined in the following article helpful:
