ORA - Maximum Connections Reached

Dear All
Even after implementing Connection pooling in our Application , we very often get this error "150 process exceede- Maximum Connection reached" ? How do we handle this? Our application is about to GoLive in another month .Please help us.
Thanks

It was simple to plan a download calendar in the case of exceeding maximum connections.
I think this rerolve.

How many connections do you need? Are you closing them properly?

... anybody have idea to solve this. In the client add code to keep track of how many connections are open
and display this and a stacktrace when you get Maximum Connections Reached Exception.
Even if you were using connection pooling
the database can still reject connections above a certain number of concurrent connections.

Application Maximum Connection Reached

Hi there,
I have installed a new Application Server and I have my forms and reports running on it. My users have receive an error as above. It seems the AS can only allow 20 max concurrent user?
How can i enlarge it? My server should be able to cater to more than that.
Thanks

If you do not need to use a proxy to connect to internet then select "Use the system proxy settings" setting or select "No Proxy".

ISA 2006 slow response, connections timeout, maximum limit reached?

Hey guys,
I've been having an issue with a client's ISA Server for the past couple of weeks and haven't been able to understand why this is happening.
They have a couple of ISA Servers Enterprise Edition in an array. This ISA Servers give Internet access to the entire company. They have significant amount of traffic through a Cisco Iron Port that all the users proxy settings are configured to this device
and the Iron Port forwards the requests to the ISA Servers.
This implementation have been working fine for months, until a few weeks back that started to have slow response problems from the ISA Servers. Analyzing the reports from the ISA Servers, I've noticed an increased amount of traffic a few times this
has happened and mostly from the Iron Port. The Cisco people says this increase amount is due to the fact that the ISA Server stops responding and new requests are made at the moment from the device. We have configured the Iron port IP in the exceptions of
the Flood Mitigation Settings of the ISA Server, and configure it to take more than 20,000 connections.
Still after this configuration, the same problem raised a couple of days back. The ISA Servers stops responding and they need to be forced shut down and restarted to get them back to work.
There are also some errors from some other internal IPs that it reaches maximum connection limits, but these are about 10 errors like this only. I was thinking maybe there are some infected computers or something but they said that they scanned the ones
that show the errors and nothing is detected.
From the ISA reports of the time of the incident, I saw that it reached more than 15,000 concurrent connections. More than double of what it usually handles throughout the day.
I don't know if there is like a connection limit that the ISA can handle before it hangs of something?
Is there any ideas on what can be happening with this?
Thanks for any replies!
Eduardo Rojas

Hi,
Have you check the Event logs on the ISA Server? Any error?
You could use ISABPA to do some basic troubleshootings.

ORA-02399: exceeded maximum connect time, you are being logged off

What could have been the cause of "ORA-02399: exceeded maximum connect time, you are being logged off"? I am always getting that issue even if I am continously doing some query.

There's a resource limit active (RESOURCE_LIMIT=TRUE in pfile/spfile) and a user_profile (which limits the connection time) dedicated to the user.

Who can help me to review the question? -"ORA-02019: connection description

Any help from you would be appreciated!!

Hello,
you have to fix the basic problem,ORA-02019 means your remote database cannot be reached because of an invalid connect string. So it's also impossible to do a COMMIT FORCE,same reason.
ORA-30019 is due to a bug, document 274321.1 in metalink describes what to do. Here's an extract:
If you get the following errors while purging transactions using "dbms_transaction.purge_lost_db_entry"
SQL> EXECUTE DBMS_TRANSACTION.PURGE_LOST_DB_ENTRY('5.23.2386');
BEGIN DBMS_TRANSACTION.PURGE_LOST_DB_ENTRY('5.23.2386'); END;
ERROR at line 1:
ORA-30019: Illegal rollback Segment operation in Automatic Undo mode
ORA-06512: at "SYS.DBMS_TRANSACTION", line 65
ORA-06512: at "SYS.DBMS_TRANSACTION", line 85
ORA-06512: at line 1
Fix:
===
This problem is logged as
Bug.2191458 (unpublished) UNABLE TO EXEC DBMS_TRANSACTION.PURGE_LOST_DB_ENTRY WITH AUTO UNDO MANAGEMENT and is worked by development.
Use the following workaround:
You have to use local_tran_id.....
Issue commit before alter system set "_smu_debug_mode" = 4;
Follow the steps,
SQL>commit;
SQL> alter session set "_smu_debug_mode" = 4;
SQL>execute DBMS_TRANSACTION.PURGE_LOST_DB_ENTRY('local_tran_id');

DBMS_RANDOM and ORA-01436: CONNECT BY loop in user data

Hi,
The following query gets the error "ORA_01436: CONNECT BY loop in user data":

currentdate is unique.
If I hard-code any one set of values, like this:

                                               );I can get the correct results from dual. I was looking for a way to extend this to get multiple rows from table_z in the same query.
The problem came up in [this thread|http://forums.oracle.com/forums/thread.jspa?threadID=894946&tstart=0], where the problem is:
Given this table:
CREATE TABLE     table_z

,      days          NUMBER
INSERT INTO table_z (currentdate, months, days) VALUES (TO_DATE ('03/02/2006', 'MM/DD/YYYY'),     0,     300);
INSERT INTO table_z (currentdate, months, days) VALUES (TO_DATE ('04/05/2006', 'MM/DD/YYYY'),     10,     0);
INSERT INTO table_z (currentdate, months, days) VALUES (TO_DATE ('05/04/2006', 'MM/DD/YYYY'),     3,     0);I'm trying to add the given number of months and/or days to currentdate until I reach a given hard-coded cutoff date (05/01/2008 in this case).
That is, the desired results from the data above are:
CURRENTDAT     MONTHS       DAYS FINALDATE

Error Ora-3134, connection to Oracle 9.2.0.6

Hi,
I want to create connection from Windows 2008 server 64 bit to Oracle database version 9.2.0.6.
I have installed "Oracle 11g Release 2 ODAC 11.2.0.1.2 with Oracle Developer Tools for Visual Studio" where in installation instruction I have found following requirement:
"Access to an Oracle Database Server (Oracle 9i Release 2 or later)".
After that I create simple .net application using Oracle.DataAccess.dll version 2.112.1.2. But while connecting I have error Ora-3134 Connections to this server version are no longer supported.. Do you know why I have this error?
Thanks for any help
Mark

Hi,
You should not get that error with 11.2 client and ODP and a 9.2.0.6.0 database as they are supported. The 9.2 end must be 9.2.0.4.0 or higher which you seem to have.
Do you get the same error running SQL PLUS from the same 11.2.0.1.2 home and connecting to the same database?
Are you verified by some other means like client side SQL NET tracing that you are indeed connection to the a 9.2.0.6.0 DB and not some lesser version?

Hi Guys,
Thank you both for your responses, my findings are as follows:
1. HOST=X.X.COM, ensure host is reachable : PING works and host(s) are reachable.
2. In RAC Env, ensure TNS Name is correctly spelled, spelling fine, i can connect with the tns name (is TNS name same as SERVICE_NAME?) by: sqlplus 'user/user@racenv'; but my efforts still will not allow me to use:
sqlplus 'user/user' it tells me that the host or object is does not exist, does this refer to the actual physical machine or the service name, or the instance name?
All host entries in my tnsnames.ora file refer to the vip addresses of both servers holding the rac installation, and both are resolved just fine, testing with ping; any other way to test this?
tnsnames file contains CONNECTION strings in the following order (does the listener entry need to be in the file? on the machine that i am trying to connect from?):
LISTENER_ORCLTELE =
(ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.3.9)(PORT = 1521))

ORA-28500: connection from ORACLE to a non-Oracle system returned this message: ORA-02063: preceding line from OWB_75

ORA-28500: connection from ORACLE to a non-Oracle system returned this message: ORA-02063: preceding line from OWB_75
Scenario:
I am having difficulty getting ODBC connection between Oracle OWB app with an 11gR2 DB (running on a VirtualBox Linux) and SQL Server 2008 running directly on the host. (Windows 8)
I am trying to take a SQL Server 2008 feed into Oracle Ware house Builder, and think(!) I have read everything and configured it in accordance (but I presume not given 3 days of failed attempts to fix it). I have also read several blogs, hence there might be a few more settings in the configuration files than the formal documentation says, but these have come from blogs that have “Solved” problems for other similar situations.
The environments:
HOST:
Name: RESOLVEIT-PC
IP: 192.168.1.80
Windows 8 (64bit) , with system DSN ODBC connection ACME_POS created with 32 bit ODBC set up (This setting still shows up fine in the 64 bit ODBC).

Let us rewrite your ODBC DSN a little bit... Your current odbc.ini looks like:
[ACME_POS]
Driver     = FreeTDS
Description = ODBC Connection via FreeTDS
Trace       = 1
Servername = 192.168.1.80
Database    = dbo
Let us change it a little bit so that we only need one config file - no odbcinst.ini nor freetds.conf file anymore:
[ACME_POS]
Driver =/usr/local/lib/libtdsodbc.so
Server = 192.168.1.80
Database
= dbo     #### I have some doubts that you have a SQL Server database called dbo - one database that always exists is master - so as a test use master here or get the real database name of the SQL Server database you want to connect
Port = 60801 ## make sure it really is the correct port - best would be to check on the SQL server and then try telnet <ip> <port> if you can connect to the SQL server
TDS_Version = 8.0
QuotedId=YES
Especially the last 2 parameters are mandatory. TDS_Version specifies the TDS Version you have to use to connect to the SQL Server and QuotedID is required for DG4ODBC as it surrounds objevt names by double quotes.
What happens now when you try to connect with for example isql - the ODBC test utility shipped with the ODBC Driver manager?
In addition, could you please do me another favour and check the word size of DG4ODBC and the ODBC Driver Manager as well as the ODBC Driver - just execute:
file /u01/app/oracle/product/11.2.0/dbhome_1/bin/dg4odbc
file /usr/local/lib/libtdsodbc.so
file < the patch to your libodbc.so library>/libodbc.so
and post the output.

How to bypass "ORA-01436: CONNECT BY loop in user data" ?

Hello everybody
I have a problem with a ORA-01436 firing too early on a query I'm trying to execute.
There is a table of strings. Each string on that table should be composed of a single character or it must be obtained by the concatenation of a single character on another string in the table.
Sometime this requirement is missing. I can't do anything to drive the table to be in that way. So I would like to execute a query witch corrects that table by adding the missing strings in it. When there are some strings that can't be obtained by appending a single char from another string the the query should list also the missing chain of strings to make that string valid in the table.
An example.
create table strings (
     val varchar2(10) not null
insert into strings (val) values ('A')
insert into strings (val) values ('ABCDE')
insert into strings (val) values ('AD')
insert into strings (val) values ('ADF')
select *
from strings
order by val
Query finished, retrieving results...
    VAL
A
ABCDE
AD
ADF
4 row(s) retrievedAs you can see the bold string ABCDE is not valid because it can't be obtained by
appending a single char to any other string in the table.
In this case a valid result should also list the chain of strings 'AB', 'ABC' and 'ABCD'.
To find the strings where a chain of missing strings begins and finishes I use this query.
Processing ...
select val,p_val
from (
     select val,lag(val) over (order by val) as p_val
     from strings
) a
WHERE val not like p_val||'_' and val like p_val||'%' AND p_val IS NOT NULL
Query finished, retrieving results...
    VAL       P_VAL
ABCDE      A
1 row(s) retrievedIn this simple case a can list the missing strings with this query.
Processing ...
select val,p_val,p_val||SUBSTR(val,LENGTH(p_val)+1,LEVEL) as chain_string,LEVEL
FROM (
select val,p_val
from (
     select val,lag(val) over (order by val) as p_val
     from strings
) a
WHERE val not like p_val||'_' and val like p_val||'%' AND p_val IS NOT NULL
CONNECT BY LENGTH(val)>LENGTH(p_val)+LEVEL
Query finished, retrieving results...
    VAL       P_VAL       CHAIN_STRING                      LEVEL
ABCDE      A          AB                                                        1
ABCDE      A          ABC                                                       2
ABCDE      A          ABCD                                                      3
3 row(s) retrievedBut when I have more than one string to be validated things change and the hierarchical query is not good any more in this way.
insert into strings (val) values ('ADFGH')
Processing ...
select *
from strings
order by val
Query finished, retrieving results...
    VAL
A
ABCDE
AD
ADF
ADFGH
5 row(s) retrievedBecause I retrieve solutions regarding the one string mixed with all the others
Processing ...

ABCDE A ABCD 3
6 row(s) retrievedTo avoid this I should add a condition to link val to prior val in the connect by clause but here it throws ORA-01436.
Processing ...
select val,p_val,p_val||SUBSTR(val,LENGTH(p_val)+1,LEVEL) as chain_string,LEVEL

select val,p_val,p_val||SUBSTR(val,LENGTH(p_val)+1,LEVEL) as chain_string,LEVEL
ORA-01436: CONNECT BY loop in user dataWhat could I do to bypass that check?
I know I could query for distinct values on the first query (the one without the condition val = PRIOR val ) but I'd like to know if you had similar problems and how did you solved them in this case.
Thanks

Starting Oracle 11gr2 Im getting Error: ORA-03135: connection lost contact

Hi Guys!
Thanks for your advises. I still working toward a resolution.
But I encountered another issue from Enterp Manager :
ERROR : Please correct the following error: Connection string must be specified.
My connection has this format:

Please tell me what is wrong here. Thanks. Dan.
