9i Connection Manager Resource Leak?

I am experiencing serious performance problems with the Connection Manager gateway (CMGW.exe) that ships with Oracle9i for Windows NT/2K.
There appears to be a memory leak after the first connection to the Connection Manager is made. I've come across mention of a similar problem with CMGW on Solaris. Is there a fix for this problem?
Background: my students are building Java applets to connect to Oracle9i via Oracle9i application server. The applets are hosted on the application server, so I was planning on using Connection Manager to hit the database from the application server. It works fine the first time, but due to the memory leak the application server slows to a crawl whenever another connection is attempted.
Thanks,

Use the same as you were using in 8i. Just upgrade your client (if required).

Database Table Resource via Oracle RAC connection Manager

Hello,
Our current IDM 8.1 syncs off a HR Database Table using the Database Table connector.
Our DBA's are moving the view into an Oracle RAC environment.
Question: Is there a way for us to connect and sync off our DB table through an Oracle RAC connection manager.
I understand that for the IDM repository, this is possible.
jdbc:oracle:thin@(DESCRIPTION =
(ADDRESS_LIST =
(LOAD_BALANCE = ON)
(FAILOVER = ON)
(ADDRESS = (PROTOCOL = TCP)(HOST = server1.ser.com)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = server2.ser.com)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = db.com)
servers server1 and server2 are oracle connection managers
Thank you for your input,
-RC

We moved the repository to Oracle RAC recently. The syntax to switch to the new databasecluster was something like this:
lh setRepo -tOracle -ujdbc:oracle:thin:@//dbcluster1.domain:1521/service_idm.oradb.domain -Uwaveset -Pwachtwoord
For the 'lh setRepo' command the old database had to be up, and we had to use the old ojdb5.jar. After that we switched to ojdb6.jar.
One of our resources is a database table with HR data in the same database. The following Database Access Parameters work for us:
Database Type:      Oracle
JDBC Driver:      oracle.jdbc.driver.OracleDriver
JDBC URL Template:      jdbc:oracle:thin:@//%h:%p/%d
Host :     dbcluster1.domain
Database: service_idm.oradb.domain
Port: 1521

Oracle Connection Manager

Hi,
i'm having a problem configuring Oracle Connection Manager. It does start the instance of connection manager
Summary of my environment is
10g Application server and infrastructure machine OS: Windows 2003
9i Database Server: Windows 2003
Client : Java Applet
JDBC driver type : THIN
Installed: 10g Infra first and then 10g midiier(portal and wireless) in seperate oracle homes on the same machine. Eveything is up and running as i was able to login seperately in infra and midtier enterprise managers.
Final Goal : Trying to connect to an Oracle 9i database on a differnt machine than the appserver using an applet, thin drivers and Oracle Connection Manager
Problem : Connection manager instance not started however cmanADMIn service started.
CMCTL:CMAN_oracle9-app> administer cmanOracleAS
Current instance cmanOracleAS is not yet started
Connections refer to (address=(protocol=tcp)(host=10.10.1.101)(port=1610)).

Certificates in lieu of Oracle connection Manager for our Applets -- Help!!

I support an application named IDEA out of New York. The IDEA application is an INTRANET application for use within our company Firewall.
Currently, the IDEA application's front end resides on a Windows 2000 Server running IIS 5 and JRun 3.0. The back-end runs on Oracle 8.1.7 database on a UNIX Database Hosting Utility (DHU). Our applets communicate with the back-end database using Oracle Connection Manager that is installed on the Web Host.
We are trying to migrate to the DWeb environment (Linux cluster). The linux cluster is running Apache Tomcat. We have been told that installing Oracle connection manager is not a viable solution (our company does not support it). Because of this our applets cannot communicate with our database. Below is a brief description of this limitation and also the work-around.
====================================================================================================================================================
Connecting to the Database through the Applet
The most common task of an applet using the JDBC driver is to connect to and query a database. Because of applet security restrictions, unless particular steps are taken an applet can open TCP/IP sockets only to the host from which it was downloaded (this is the host on which the Web server is running). This means that without these steps, your applet can connect only to a database that is running on the same host as the Web server.
If your database and Web server are running on the same host, then there is no issue and no special steps are required. You can connect to the database as you would from an application.
As with connecting from an application, there are two ways in which you can specify the connection information to the driver. You can provide it in the form of host:port:sid or in the form of a TNS keyword-value syntax.
For example, if the database to which you want to connect resides on host prodHost, at port 1521, and SID ORCL, and you want to connect with user name scott with password tiger, then use either of the two following connect strings:
using host:port:sid syntax:
String connString="jdbc:oracle:thin:@prodHost:1521:ORCL";
conn = DriverManager.getConnection(connString, "scott", "tiger");
using TNS keyword-value syntax:
String connString = "jdbc:oracle:thin:@(description=(address_list=
(address=(protocol=tcp)(port=1521)(host=prodHost)))
(connect_data=(sid=ORCL)))";
conn = DriverManager.getConnection(connString, "scott", "tiger");
If you use the TNS keyword-value pair to specify the connection information to the JDBC Thin driver, then you must declare the protocol as TCP.
However, a Web server and an Oracle database server both require many resources; you seldom find both servers running on the same machine. Usually, your applet connects to a database on a host other than the one on which the Web server runs. There are two possible ways in which you can work around the security restriction:
You can connect to the database by using the Oracle8 Connection Manager.
or:
You can use a signed applet to connect to the database directly.
These options are discussed in the next section, "Connecting to a Database on a Different Host Than the Web Server".
Connecting to a Database on a Different Host Than the Web Server
If you are connecting to a database on a host other than the one on which the Web server is running, then you must overcome applet security restrictions. You can do this by using either the Oracle8 Connection Manager or signed applets. ====================================================================================================================================================
It was suggested that we implement signed applets (it is our only alternative at this time). This is where, hopefully, you can help me. We are unfamiliar with using certificates and signing applets. We need to obtain certificates that will allow our applets to connect to our oracle database on the DHU. What kind of certificates do we use? Are their coding examples of how to use these certificates? We have a CA within our company but they cannot tell us what kind of certificates we need. How many certificates do we need? Do we install any certificates on the backend database server? Any information would be greatly appreciated. We are basically trying to get our applet to work outside the sandbox by establishing a connection to the database server.Thanks in advance for your time.

If you want to connect to the database from the applet there is a third option.
Since this is an intranet application you have control over the desktops using this
application. In our company the jre ignores signed applets (as it should) because
it gives control to the user to run potentially harmfull applets from the Internet.
The way to dish out special privileges to applets is the policy, put a policy file on
you intranet and have the jre use it by specifying its URL in the java.security.
Here is some more info about security configuration of the jre:

We use Oracle jinitiator to run Oracle forms but I am not involved in that project
and do not know a lot about it. It does perform quite good though.

What is meant by a resource leak ?

What is meant by a resource leak ?

Garbage collection manages only memory, not other system resources. If your Java program has plenty of free memory, garbage collection will not be triggered automatically. Usually, however, there are other resources that are more limited than memory. For example, all OSes have limits on the number of sockets, file handles, etc. that can be open. Sometimes this limit is quite low. This is true even on a desktop, e.g. if your system has 128KB of memory, your Java program can easily allocate all the available file handles without coming near to filling up the heap. If this happens, your Java program will fail. This is what we call a resource leak; the unintentional maintenence of references to non-memory resources.
This is why it is important in Java to explicitly manage non-memory resources. Classes which utilize non-memory resources should provide ways to explicitly allocate/deallocate those resources, independent of garbage collection. For example Socket, InputStream and OutputStream each provide explicit close() methods for deallocation of file descriptors, Window provides a dispose() method to free the window handle, etc. The way to properly use these classes is to allocate using the constructor, then deallocate using the appropriate method (deallocation is preferably done in a finally{} block, so it will execute whether or not an exception is thrown during use). These classes do release these non-memory resources in their finalize() method, but remember that the finalizer only gets called by the garbage collector, and if the object is never collected, it will never be finalized, hence will never release the resources.

Source Routing - Connection Manager

Hi,
I need some help understanding the following source routing function of Connection Manager. The book says:
"Source routing is used with Connection Manager. CM servers as a proxy server for Oracle Net traffic, enabling Oracle Net traffic to be routed securely though a firewall. Oracle Net treats the addresses as a list of relays, connecting to the first address that then requesting to be passed from the first to the second until the destination is reached. It differs from failover and load balancing in that all addresses are used each time a connection is made".
I do understand it is possible to configure CM in such a way that it can act as a firewall, accepting and rejecting connections based on certain criteria. What I do not understand is the second part where the addresses are treated as a list of relays. Why would something like this be necessary and how could that be configured in CM.
Any help would be greatly appreciated....
Thanks in advance.

Parallel Script Tasks Using Same Connection Manager are Corrupted

We're seeing a bizarre issues in our SSIS package. We are using an HTTP connection manager in multiple script tasks running in parallel and the connections seem to be getting mismatched. Here's the basic flow.
We have 6 containers that run in parallel. Each container does the exact same work (they are copy/pasted) except we change the value of a variable representing the report to generate that is scoped to each container. The container runs a query
(using a SQL connection manager defined in the package designer) and then uses a foreach container to enumerate the rows. The variables inside the foreach container are scoped to it so we don't have a scoping issue. Within the loop we write
the variable values to a log table, use a script task to generate an SSRS report and then write all the data and the report to an external system. Everything is working fine except for the generation of the report.
Within the report script block we acquire a connection to a HTTP connection manager that is defined in the package (just like the SQL connection manager). We then create a new HttpClientConnection with it and update the URL to include the necessary
parameters that SSRS needs to generate the report. We then download the results and return it back to the container. Here's the basic code we use
var httpConn = Dts.Connections["ReportServerUrl"];
var clientConn = new HttpClientConnection(httpConn.AcquireConnection(null));
var uri = new UriBuilder(clientConn.ServerURL) { Query = reportQueryInfo };
clientConn.ServerURL = uri.Uri.ToString();
clientConn.DownloadData();
The issue we are seeing is that when 2 of the scripts run at the same time the ServerURLs are getting cross wired such that we see 2 of the same report being requested rather than 1 of each type that we had requested (based upon the SSRS execution logs).
It's almost like we are getting a shared HTTP client connection. Provided the scripts don't run at the same time everything works correctly. We are confident our variables are set correctly because we are storing them both before and after in external
tables and they are always correct. The URL calculation logic is also correct because this problem only occurs when 2 requests are sent in parallel.
What am I missing here?

Thank you for the feedback. Before I go to Connect I'd like to provide some more info that may provide a better idea of what the problem is.
We broke things down trying to replicate the issue and it isn't a conn mgr problem after all I believe. To clarify our package, we have 4 containers that execute the same logic (they were copy/pasted) except for the variable values that we set. The
containers are not linked together so they run in parallel. Each container executes a query using the ADO.NET conn mgr. A foreach loop captures the value for the current row and then calls SSRS using a script block, forwards the report onto an external
resource and then updates a table indicating the row has been processed. The only difference between them is the parameter we pass to the query and the value of the variables (that are scoped to the container or foreach loop).
The problem we have found is that the very first time through the foreach loop ALL containers are using the same row (from the first container's query). Second and subsequent rows are fine. We initially thought the queries were fine because of
our update at the end of the foreach loop but it is now clear that isn't the case.
We saw this problem when we moved our package to production. We went back to Dev and was able to replicate it as well. It happens every time and it is always the same row when given the same input set. We started eliminating containers
and we found it only happens when you get to 3 containers or more. 2 containers had no problems.
I'll try to replicate it on a simpler solution but any thoughts on whether there is a race condition or something in SSIS would be helpful.

Remote Desktop Connection Manager can only open 6 sessions at a time on Server 2012

I am only able to open, and view thumbnails, for a maximum of 6 RDP sessions on my Server 2012 box at a time in Remote Desktop Connection Manager (RDCM). If I add more sessions I just get a variety of connection errors for the additional sessions. If I activate
a 7th session one of the existing 6 sessions goes off-line with a connection error message. Sometimes the error says 3334, sometimes the error says 0x8345000E, and sometimes it just says there is a connection error.
I have checked Group Policy on the server to ensure I don't have any settings restricting the number of RDP sessions.
In fact, I will often have 30 or 40 RDP simultaneous sessions opened, I am just not able to view them all in RDCM. I have seen reviews of RDCM with screenshots showing dozens of thumbnails so it seems to be something that's possible to do.
Are there any settings I should make on the server to allow RDCM to connect to more than 6 simultaneous RDP sessions?
Just to be clear, all these RDP sessions are running on the same server. Also, I am just using the trial license for Server 2012 and Remote Desktop Services right now. I don't think that should have an impact, but I wanted to be thorough.

Thanks Jakub for "corflags" info.
Unfortunatelly it doesn't work because running mRemoteNG.exe process in 64bit can't load MSTSC ActiveX component (referenced assemblies) because original files were assembled from 32bit dll [mstscax.dll]?
Error message when making RDP connection:
Could not load file or assembly 'Interop.MSTSCLib, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. An attempt was made to load a program with an incorrect format.
I was able to create new AxInterop.MSTSCLib.dll and Interop.MSTSCLib.dll assemblies from 64bit dll version and now it works with "AnyCPU":-)
http://www.filedropper.com/axinteropmstsclib-mremoteng
Using AxImp.exe and TlbImp.exe didn't worked for me because it creates assemblies in wrong namespace "MSTSCLib" instead of "Interop.MSTSCLib" (AxImp.exe) and TlbImp.exe for changing namespace generated many "marshaled errors"
so final .dll wasn't working.
Adding MSTSCAX.dll reference in Visual Studio directly created correct and functional assemblies. Who don't know how to create 64bit compatible assemblies or don't have Visual Studio, feel free to check linked file.
Hope it helps
P.S. Sorry for possible technical misinterpretation, I am not programmer so creating new assemblies was trial-error process...

Excel Connection Manager suddenly can no longer connect to Excel from SSIS package

to reproduce that error code since. Now I am only getting the above error message.From the time I created the original package (when it worked fine) until now, I have been using the same computer, writing to a (32 bit) 2010 Excel file in
a local folder. The filename and location have not changed. The ConnectionString has not changed. The Connnection String I am using is Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Conversion\Conversion Results_dt01.xlsx;Extended Properties="EXCEL
12.0 XML;HDR=YES;". Now an attempt to create and test a NEW Connection Manager yields me this error. "Test connection failed because of an error in initializing provider. Unspecified error.",  whereas before I had
no problems creating a new connection manager.I checked a second SSIS package, which I also built during the past 3 months, which loads multiple sheets from multiple Excel files to a SQL Server 2008 database holding table. It uses the same
ACE OLE DB 12.0 connection to load the Excel speadsheets and this package continues to work fine on the same workstation.In desparation, wondering if the Microsoft ACE OLE DB 12.0 driver had become corrupt (even though the second package
was raising no errors), I did download and install the Microsoft ACE OLE DB 12.0 driver.  That did not solve my problems with the first package.I need to get this package running again ASAP as it is targeted for UAT testing in a
matter of days. Any help with this issue would be greatly appreciated!

I submitted this issue above and now I am having the same problem again. I am using the same local computer, the same operating system (WinXp v 5.1.2600 SP3 Build 2600) as originally described. I am working with the same SSIS package that
writes multiple query results (reports) to an excel spreadsheet. This package has been successfully executed multiple times, but now I am suddenly getting the same error as follows:
Error at 1ConversionContacts [Connection manager "Excel Connection Manager"]: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80004005.
An OLE DB record is available. Source: "Microsoft Access Database Engine" Hresult: 0x80004005 Description: "Unspecified error".
Error at DFlow Write soft deleted duplicate claims to Excel sheet [Excel Destination - write duplicate claim nbrs that have been removed to Excel [61]]: SSIS Error Code DTS_E_CANNOTACQUIRECONNECTIONFROMCONNECTIONMANAGER. The AcquireConnection method
call to the connection manager "Excel Connection Manager" failed with error code 0xC0202009. There may be error messages posted before this with more information on why the AcquireConnection method call failed.
The package will not run because of these multiple errors (multiple because it occurs on every single excel destination in the package).
I have Run64BitRuntime set to false on the project. I have triple checked that the excel file name (which I created and can access) exists with the correct name in the correct path, which is local on my machine. The file is the same file in the same
location as when the package worked. I am running the SSIS service under my own network login, as I was when the package worked. I have been consistently getting this same error whenever I change my network password without updating the password
in the SSIS service, but I have triple verified that the service is using my latest password. If I try to open and edit the Excel Destination in any DataFlow task I get the same error. I can successfully create a new Excel Connection Manager pointing
to the same excel file. However if I try to assign the newly created Excel Connection Manager in the data flow, I cannot activate the drop down to choose the Excel sheet without getting an 'Unspecified error' message. I then swapped out
the file with its template version, and ensured the name was updated as correct. I still get the same errors.
Oh, and the SSIS package is extracting data from a SQL Server 2008 database with an ADO.net Connection Manager using Windows authentication. I have no problems with the SQL Server connection, it has always worked and still does. It is only
the connection to excel output file which is locally stored on my machine.
Has anyone got any suggestions for me?

USB no longer available in Connection Manager afte...

Hi! I had the Init MediaControl2 problem, which I managed to fix after running through numerous reinstallations and cleaning (with the Nokia registry cleaner 3.3)
However I found that even though the PC suite is now installed, the USB is no longer shown as one of the options under Connection Manager. Also I found that there is no 'Nokia Connectivity Cable Driver' installed (checking the Add/Remove Program). I have only
Nokia PC Suite
Nokia Connectivity Solution
Tried to reinstall many times but never get Nokia Connectivity Cable Driver back. Here's what I've done so far
- Repair
- Used all options under Nokia Cleaner 3.3 - Deleted all registry entries that contain the word "PCSuite" or "Nokia" by using some registry management tools
- Reinstalled PCS 6.7, and updated to 6.8
- Used the regsrv32 on the dll that manages the USB connection - C:\Program Files\Common Files\PCSuite\Transports\NCLUSBMM.dll, but returned error 0x8040020
- Tried to install older version of USB cable driver 1.59 but the installer said there's new version
- Tried to reinstall the current "Nokia Connectivity Cable Driver" by taking the installer from other good PC, but it said PC configuration corrupted, contact nokia support
I'm very frustrated with this problem.. it took me 5 hours yesterday to work till 3am and it has still no cure! What I need is simple, a way to remove EVERYTHING by PC Suite, and have a clean installation which I can use the USB connection. I know I could use Bluetooth, but I just don't want to give in to this problem.
My PC Specs
Operating system:
Microsoft Windows XP Build 2600 Service Pack 2
Language: English (United States)
Nokia PC Suite: Version 6.80.20
Language: English
Connectivity Cable Drivers: Unable to install!

Apple has never fully committed support of the Time Machine/Airport Extreme combination. I have a Airport Extreme 6th gen that supposedly supports the Time Machine, (page 13 of the installation manual). After a year of experience I have concluded that it does not work - period. If you have any critical data on your system(s) I would recommend that you use a dedicated backup/recovery product like Carbon Copy Cloner.

Connecting managed server to cluster's administration server

Hello,
I have a problem when trying to connect managed server to cluster's
administration server.
When starting the managed server I get a security exception:
[javax.naming.AuthenticationException [Root exception is
java.lang.SecurityException: Administrators must log in over admin port with
admin protocol.]]
weblogic.management.configuration.ConfigurationException: admin URL:
t3://192.168.14.15:7001 - with nested exception:

at weblogic.t3.srvr.T3Srvr.run(T3Srvr.java:169)
at weblogic.Server.main(Server.java:35)
I get the same result when testing the connection setup with
java weblogic.Admin -url 192.168.14.15:7001 -username system -password xyz
CONNECT 1
Background for this problem:
I'm trying to evaluate WLS6.0 clustering for my RMI services. I have two
machines setup with my test domain (DEdomain) and one cluster (DECluster)
within it.
In administration server (machine A) I defined two servers to be run in
machine A and machine B:
DEserver2 in machine B (to be started as managed server) and DEserver3
in machine A
I'm going to bind a same service into these above servers of my DECluster.
In machine B's startManagedWeblogic.sh I have:
java -ms64m -mx64m -classpath
$CLASSPATH -Dweblogic.Domain=DEdomain -Dweblogic.Name=$SERVER_NAME -Dweblogi
c.management.server=$ADMIN_URL -Djava.security.policy==$WL_HOME/lib/weblogic
.policy -Dweblogic.management.username=system -Dweblogic.management.password
=$WLS_PW weblogic.Server
In machine A I have administration server DEserver1 listening port 7001.
And for the domain and cluster building I followed all relevant e-docs
manual pages. It's still somewhat blurry what kind of preparations I have to
make in managed server side to join the domain; for example do I have to
have identical domain directory structure within machine B and do I have to
configure something with admin console or is everything handled by
connecting to the administation server and reading the domain's config.xml
from machine A.
I'm sure I have missed some fundamental idea for building clustered services
and would greatly appreciate if someone had any good tips or ideas.

Harri

Hi Kumar,
and thank you. That fixed my problem

It appears you had set the administration port & listen port on the admin
server.
Logging onto admin server via admin port is broken currently. I wouldsuggest
you to set only listen port
and see how that goes.

How to connect to lined server in SSMS in SSIS connection manager

Hi,
In SSMS (Server name is sqlssisdw1), I have one (SQL Server)linked server name sql4. in that linked server there is DB called rptdb
Now using SSIS I want to use tables in that DB rptdb.
So for this I want to create Connection manager, but for this when I select 'New OLEDB connection' and in that in 'Server Name' when I wrote 'sql4' it is not giving me list of DB. I also tried giving sqlssisdw1 in server name and see if I can see this
rptdb but I can't.
Can you please tell me how can I connect to lined server in SSMS in SSIS connection manager? Thank you.
Vicky

Hi ,
if you are already having access and login credentials to the remote server which is configured in sql4 , you pretty much directly connect to that server from the connection manager instead of going through a linked server. If you still want to connect
through the linked server , you need to establish the connection for SQL Server sqlssisdw1 and then
use a 4 part name query to access the rptdb tables as like below
SELECT * FROM SQL4.rptdb.<schemaname>.Tablename

My Firefox icon will not connect to the internet without manually opening my connection manager first. Why? How do I fix this issue?

I installed Firefox on our home computer this weekend (Dell). This is the browser that I use at work and I'm very happy with it.
Since installing I always have to manually open our connection manager to go online. I can't just click on the Firefox icon and have the connection manager automatically come up.
I have already checked the "no proxy" box as suggested. Firefox is set as our default browser.
Internet Explorer was our previous browser and it was so slow, but at least it automatically brought up my connection manager.

Used iTunes to download 6.1.2 to the iPad Mini. It then worked for (app store and all) for 3 hours. Then wifi stopped working at all. Hurray!

How can I find out the server port for a secured FTP site and creating a FTP Connection Manager

I have to create a FTP Task to go out and get the files that our 3rd party vendor will be dropping on a secured FTP site. I have all the credentials to access that Secured FTP Site and have successfully done so through FileZilla.
Now I need to set-up a FTP Task to go out and get their files and in so doing create a FTP Connection Manager. Is there any way I can determine the
Server Port number from the Secured FTP site? I let it default to 21 and tried the Test Connect and it failed.
Thanks for your review and am hopeful for a reply.

Hi ITBobbyP,
SSIS has a built in FTP task, while this only works for the FTP protocol, it doesn’t support SFTP. But there are some free clients like WinSCP and
SSIS SFTP Task Control Flow Component
available in the CodePlex which can invoked from SSIS.
References:
SSIS SFTP Task Control Flow Component approach
WinSCP approach
Thanks,
