Number of connections made to database at a given time

Hello,
I would like to know the number the history and current number of connections made to the database via oracle application server at a given time. I see Active Connection when I click on HTTP Server, but I am not sure what that means. Does that mean the number of users on the site or does it mean the number of connections made to the database?
Also is there a way to find out the history of connections? Also is there a log file that all this information is recorded into?
Thanks for your help in advance.

Hi
Active Connections in HTTP Server -> Number of users connected to your site (active + inactive)
You can get information about database connections in v$session, or , in Enterprise manager -> OC4J container -> Home
If you are using datasources at application level you can get information about pooling in
Entreprise Manager -> 0C4J Container -> Application (select application ) -> DataSources
If you have datasources at OC4J container level you can get info in Entreprise Manager -> OC4J container -> Administration -> datasources

Could not get connections for 2 databases at the same time

Hi, I have a session bean which calls 2 entity beans in one method. The 2 entity
beans are located in different databases (different datasources and different
pools). When running, I got the following error:
Couldn't get connection:
java.sql.SQLException: Connection has already been created in this tx context
for pool named iitga_jdbc. Illegal attempt to create connection from another pool:
iitdbmap_jdbc
It seems WebLogic only allows one database connection within one method.
Thanks,

Hi Henry,
If you want two beans bound to different database, you need
to use XA pools with TXDataSources because in this case you
have a distributed transaction.
Set up you pools using XA drivers and make sure you use
TXDatasources.
If you tell us which database you use we may come up with
sample pool configurations.

Monitor database connections in a database pool

Hi,
Do you know how I can monitor database connections in a database pool.. ? I am using Jboss container.
The purpose is to monitor connections that are closed and refresh them.
Thanks,

There a firewall.. across which my application makes connections to the database.. the firewall times out due to the inactivity. and my application dies.
I was thinking may be I could check for the database connections in a pool and then one that is not being used for a long time .. close it and again refresh the connection.
Please Advise...

How to find the number of ODBC connections to Oracle Database

Hi All,
How to find the number of ODBC connections and all connections to the Database in last week. Are there any views to get this information?
Thanks in advance,
Mahi

What Ed said is true that Oracle doesn't note which type of protocol is connecting to the database, however, you can see which program is accessing the database.
For example: if you already know of a user using ODBC, you can verify as:
select username, osuser, terminal, program from v$session where username = 'SCOTT'
USERNAME                 OSUSER          TERMINAL   PROGRAM
SCOTT                    IUSR_SRV231     SRV231     w3wp.exe
SCOTT                    IUSR_SRV231     SRV231     w3wp.exe
2 rows selected.Assuming that you can confirm the progam noted in the above (example) is the one using ODBC, then you can change the query such as:
SQL> select username, osuser, terminal, program from v$session where program = 'w3wp.exe';
USERNAME                 OSUSER          TERMINAL   PROGRAM
SCOTT                    IUSR_SRV231     SRV231     w3wp.exe
SCOTT                    IUSR_SRV231     SRV231     w3wp.exe
2 rows selected.Just for kicks, I checked our listener.log file, but there was no reference of odbc in it either.
Hope this helps...

How to find out number of connections to database?

Hi,
How can I find number of connections connected to the database 4 hours ago. For examply, if current time is 5PM and I want to see total number of connections connected to database (and from what user?) in between 1 and 2 PM, is there a way to find that out?
I see v$session has a column MACHINE from which I can use count function to check the # of concurrent connections but I am not sure how to check the # of connections that happend few hours ago. Any suggestions?
--MM

you should have audit on .. and create logon trigger and make entry in the tabe ..that would give you .

Problem with reached maximum number of connections to database

Dear Experts,
Our Production system was not responding properly last week.
The below was the reply from the Basis team.
"It seems that we have again problem with reached maximum number of connections to database. We have extended this number to 100 this year and now it seems that it’s not enough again. It seems that something is running on Production, which takes over too many connections."
They have increased the number to 200 as a work around.
Do we have any means to find out, which component or application is causing the issue.
Please advise me if any better way is available to correct the issue.
Please see the below trace.

Problem with upgrade due to no connection to audit database

Hello everyone!
Today after work I wanted to finally upgrade ZCM but run into some problems.
We have three servers: Two primary servers and one database-server (OEM Sybase SQL Anywhere). All three are running on SLES 11.
I want to upgrade our ZCM11.2.4MU1 to ZCM11.3a and then to 11.3.1.
I started by upgrading the Sybase database and running dbunload according to the documentation.
Then I continued with "sh install.sh -c" and chose "Audit Database". I selected the OEM Sybase SQL Anywhere with port 2639.
Admin, password and database-name were unique. But I made the mistake to set the servername to the same as the zenworks-database. *sigh*
The installation completed.
The sybase-asa and sybase-audit-asa services couldn't run at the same time, therefore I rebooted the database-server and installed the audit database again with a unique database-name.
Before the upgrade I could start dbisql and connect without problems to backup the database. Now I cannot connect anymore without using the additional parameter: links=tcpip{host=IPorDNSName,port=2638}
Connecting to the Audit Database via dbisql is not possible, with the following message:
Code:
Could not connect to the database.
Database server not found
Ensure that the name in the "Server name" field is spelled correctly, that the network options on the network tab are correct and that the database server has been started.
[Sybase][ODBC Driver][SQL Anywhere]Database server not found
SQLCODE=-100
SQLSTATE=08001
Connection parameters:
User=zenauditadmin
Password=***
Server=zenworks_audit_database_server
DBN=zenworks_audit_database2
LINKS=ShMem
ENC=NONE
links=tcpip{host=<ip>,port=2639}
With that said, it is not possible to upgrade the first primary server because the setup routine is also not possible to connect to the Audit Server:
Code:
We were unable to create a connection to the database. Please check your
connection information.
Specify the existing ZENworks database and database authentication information
for an existing user with sufficient permissions.
The services sybase-asa and sybase-audit-asa are both running. I also restarted them a couple of times.
zenworks_database.conf and zenworks_database_audit.conf look fine.
Do you have any idea what I missed?
Is the duplicate servername still somewhere existend and prevents the proper running?
Thank you very much in advance for pointing me in any direction!

Oh boy... and no backup?
Not sure how to get the sybase back working again... my first choice in
such a case would be to make a contact to Novell, are you able to
create an SR on this?

Problem with EM (Enterprise Manager is not able to connect to the database)

Hi all,
I've Oracle DB 11g Rel.1 installed on Windows XP SP3. The database is up and running i.e. everyone can connect to the DB by using any App tool e.g. SQL*Plus, Forms, or Reports. It means that the listener and the service is running. But the problem is that when I try to start the EM I see some error messages on the webpage.
It says:
Enterprise Manager is not able to connect to the database instance. The state of the components are listed below.Database Instance (Green arrow)
Status     Open                         Details     The instance is open.

please see the attached file:
http://rapidshare.com/files/404840300/em.JPGI've already checked all the services, they are running. And when I execute emctl command I got the following message.
emctl status dbconsole
Oracle Enterprise Manager 11g Database Control Release 11.1.0.6.0
Copyright (c) 1996, 2007 Oracle Corporation. All rights reserved.
http://shiman:1158/em/console/aboutApplication
Oracle Enterprise Manager 11g is running.I have checked some documents around config files in sysman and test_orcl\sysman directories. Moreover, I have checked dbsnmp and sysman account for unlockness and password accuracy. But they did not help me to solve the problem.
My question is if every thing is working fine then what is the problem with the EM? Why it is not connecting to the DB?
Thanks.
Iman

Not able to connect remote oracle database over VPN

I can not connect remote oracle database over VPN. tnsping is ok and it shows the server information of remote database. i can also telnet the 1521 port of remote database server. I can connect the same server when it is located in the same LAN. Please help me out this is very urgent.

First, this is a forum of volunteers. There is no "urgent" here.
"Urgent" means one of two things -
1) people are dying, or
2) you have a customer-facing, revenue-producing production system that is down.
(And to get some perspective on the second case, keep the first in mind.)
For the first, you call whatever civil emergency service seems appropriate.
For the second, you open an SR with Oracle - which requires a paid-up support contract. For *them* to consider your problem "urgent", you will need to demonstrate that your problem falls under item #2. I seriously doubt your problem fits that criteria.
You don't have a support contract? Now you know the exact dollar figure that your company places on the data.
That said, you need to understand a few things about your specific problem,
First, port 1521 is only used by the listener to accept a connection request. Once it gets that request (and finds that it is for a service (sid) that it knows about, it will fork a server process and tell the requesting client that it can communicate with that server process over some other port .. a randomly chosen port number in the "high" range. It could be your vpn is blocking that other port, whereas your internal firewall is not.
But this is just an educated guess since I cannot find "can not connect remote oracle database over VPN" in any error message manual. If you had mentioned the VPN along with an actual oracle error message we could be much more precise in our diagnoses and recommendations.
---- edit 22 Sep
It occurred to me that I just assumed you were using the same client machine in both cases ... a laptop that you use both at work (local network) and home (vpn). If that assumption is false, there are probably problems with your tns setup on the home (vpn) machine.
But again, it would be much easier to help if you gave us an actual error message.

Enterprice manager is not able to connect to the database instance

hello,
I have problem with EM. I have some databases, and I worked with Enterprice Manager on this databases. First DB when I have repository is ok and EM always connect with this, but I worked on another DB some time and was ok, but three days ago when I start EM I get message 'Enterprice Manager is not able to connect to the database instance'. When I couldn't resolve this problem, I make new DB and this worked two days ok, and today I get this same message. I don't make any changes in listener and tns files.
any idea?

Failed to open the connection. Details: [Database Vendor Code: 53 ]

I'm upgrading one of our applications from Visual Studio 2005 to 2010. In the process I'm also switching our reports to run using Stored Procedures instead of Tables/Views. Everything runs fine on development machines after all the migration work. On the server however, it does not work. And I am getting the error message ""
Server is Windows 2003 Server 32 bit. And yes, I have installed the latest runtimes version 13.0.2000.0 on the server. There have been no other changes on the server other than to switch the target framework on the website in question from .net 2 to .net 4, and then to modify the web.config file to remove references to the older Crystal Reports and replace with references to the newer version.
I've seen many other threads on this "failed to open the connection" errors but none of them are my problem except there is one post that remains unanswered where someone had the same Database Vendor Code 53. I don't know what that error means, spent a considerable amount of time researching that before asking this question.
Lastly, it appears that this error only happens when the report is pulling data from a Stored Procedure rather than Tables/Views. If I re-copy the previous reports, they still work.
The ODBC drivers haven't changed, nor should they. They are fully up to date on that server machine.
I can't think of anything else that would be indicative of anything other than this is a bug. Here is the error text as it shows up in the event log:

Lots of great info here, except for the database; MS SQL? Oracle? Etc?
Database Vendor Code 53 is an error code that the CR engine simply passes straight from the database it's self. E.g.; look at your database error code and you should be able to find a verbose description of the error.
As a test, what happens if you add the report to your project and run it in the CR design part of the .NET IDE?
- A quick google search of Error 53 (for MS SQL - an assumption) comes up with a number of good hits. E.g.;

How to count number of colums ina sql database

is there a command to find out the length of a column,using rs.next possible???

is there a way of finding out the number of rows in a
database??See my first post for the number of rows in a table.
If you want to get the total rows in an entire database (cant think why) it should be possible with DatabaseMetaData.getTables() and do a SELECT COUNT(*) for each table then add the results.

Application module with no connection to the database in jdeveloper 10.1.3

I have a number of programmatic bc view objects and entity objects which i have implemented through the time from different projects and now that i have collected them i want to add all of them in a reusable application module. However i don't need a connection to the database for this application module. Is it possible to enforce the application module to circumvent the db connection?

Hi user,
Just out of curiosity, why would you use ADF BC for that - if I had a bunch of non-db data sources, I'd probably use POJOs and create POJO data controls.
I didn't look in 10g, but in 11g, the ApplicationModule has a method called getDBConnectionRequired() that you could override to see if that solves your issue.
