Unable to close backend connection

Hello Experts,
We are currently running certain Visual Composer applications in our portal 7.0. It has been observed that even after navigating away from the VC application or logging of the portal, the connection to the ABAP system does not end rather it stays in the idle mode. We are using certain RFC's for data processing in our VC model.
We have changed the connection lifetime property to 60 seconds in Visual Administrator --> Server --> Services --> Connection Container but the connection continues to remain idle, we checked for the same in SM04.
Please let us know if we are missing on some required parameter changes apart from Connection Lifetime property.
Best Regards
Gaurang Dayal

You need to change the connection timeout property.
Log in to Visual Admin --> Server --> Services --> Connection Container --> Runtime --> sap.com/com.sapportals.connectors.sap -->SAPFactory
Open tab Managed Connection Factory --> Connection Definition --> Connection Lifetime
Change the default value of 3600 seconds here and save the changes.
Best Regards
Gaurang Dayal

Unable to close JDBC connection in crystal reports

Hi,
I have configured crystal reports to use a connection acquired from a datasource created in weblogic server to generate a report. I was hoping that by calling ReportClientDocument.close() i would be closing the connected used to generate the report but that doesnot seem to be the case. I run into a situation where all my connections from the connection pool are being held by the reports and therefore get an exception in the application.
Can anyome please let me know if calling ReportClientDocument.close() will ensure that the database connection used for generating the report is closed? If no, please let me know what needs to be done in the code to ensure that a connection acquired for generating a report is closed.
Thanks in advance

Hi Sanjay,
Once connected right click on the connection an try adding filtering. Check off all except Tables and if you still don't see anything try adding table filtering to see if they show up now.
Thank you

SbRIO-9612 unable to close a TCP connection without causing TCP failure

Hello,
I'm working on a multi-server (sbRIO-9612's), multi-client (Windows PCs) application which uses the STM 2.0 libraries and LV2009 SP1. The server listens on a UDP port for the client to send a message - once sent, the server opens the TCP connection to the client and all is well . . .
. . . until I added a "hearbeat" message to monitor for down connections. Once the TCP connection has been extablished, the client PC sends a TCP message (a request for the number of clients connected) to the server sbRIO-9612 every 5 seconds - both the client and server are coded to close the connection if a message is not received within 10 seconds. The client-side app works fine - if the TCP message is not returned in 10 seconds, the connection is closed and a new UDP message is sent to re-establish it.
The server-side is the problem - if no message is received in 10 seconds, the TCP connection is closed o.k. (no errors), but the server will no longer allow new TCP connections to be established unless it's rebooted. It seems to work fine if I leave the non-communicating TCP connections open on the server-side, but I can see this leading to problems after several clients have disconnected without notifying the server properly.
Interestingly, if the client closes the TCP connection properly (via TCP Close in LV), the server detects it fine and there is no problem.
I'm allowing the operating system on both sides to select the TCP port to use.
Any help is greatly appriciated - thank you!
Al

Hi Al,
Thanks for the update -- I'm glad that you were able to find that the issue wasn't actually with the TCP VIs, and moreover that LabVIEW 2010 SP1 seems to have resolved the issue. I would still recommend combing through the code on the RT end to ensure that the LabVIEW 2010 SP1 upgrade really did 'fix' the underlying issue. It's somewhat strange that a version upgrade resolved TCP communication issues that you were having. I just want to be sure that the solution is a truly stable one.

DPS 6.2 on Windows 2003 puts backend connections to close_wait

Hi,
i was installing a couple of DPS 6.2 on Windows 2003 servers.
I defined data sources that point to PGP Universal Servers ldap key store, activated proactive monitoring to keep alive connections and poll them every 30 seconds. I open 5 initial connection, increment by 1 with a max of 100 connections.
DPS now opens these connections on startup and everything looks fine for a while, but if i wait a couple of minutes without activity from a client querying the key server through the proxy server, the DPS puts most of the connections to a close_wait state and does not really recognize that these connections are not available any more.
If another client queries the dps after a couple of minutes of inactivity, the DPS returns with error "Unable to retrieve a backend SEARCH connection to process the search request". I have to do about 5 or 6 queries until the DPS recognizes that the connections are not available any more and opens new ones. After these queries i get fine replies but if i have another inactivity for a while the error happens again.
Any ideas how i can get DPS to gracefully close these TIME_WAIT connections or at least to meka sure these connectons stay alive? Polling and pro active monitoring did not solve the problem
thanks
.andi
some more information:
it seems as if the DPS is only polling one of the connections to the LDAP backend server to keep the connection alive, it does not poll al connections. here is the logfile from openldap running on 1389 on the backend:

Hi andi,
As you've noticed, DPS uses a dedicated connection for server health-check.
The problem you mention may appear when LDAP directory servers are configured to drop inactive connections after x seconds, x > health-check polling period and no traffic received by the proxy.
Indeed, health-check does not detect anything wrong as periodic traffic prevent the dedicated heath-check connection from being dropped. However, pooled connections remain inactive, so they become stale.
The number of (potentially) stale connection increase with the size of the pool, that's the reason why you need to do multiple (failing) queries to clean up the connection pool.
Error detection is improved in 6.3 (out beginning of CY08) when a stale connection is retrieved from the connection pool.
Meanwhile, it is possible to configure the proxy to periodically generate (dummy) traffic to those pooled connections that remained inactive for some time. This usually solves this kind of problem at the expense of extra outgoing network traffic when the proxy is not used.

Unable to get a connection for pool - ResourceUnavailableException

Hi
I have a BPEL process which starts a child instance of another asynchronous BPEL process for each message in an XML file. The child BPEL process makes a call to the Oracle Apps JCA Adapter to push the data into E-Business Suite.
All works perfectly except when the number of messages exceeds a certain limit (15 or so). The error received is as follows:
"Exception occured when binding was invoked.
Exception occured during invocation of JCA binding: "JCA Binding execute of Reference operation 'SyncPersonRecord' failed due to:
JCA Binding Component connection issue. JCA Binding Component is unable to create an outbound JCA (CCI) connection.
ebsPeoplesoftEmployees:SyncPersonRecord [ SyncPersonRecord_ptt::SyncPersonRecord(InputParameters,OutputParameters) ] :
The JCA Binding Component was unable to establish an outbound JCA CCI connection due to the following issue:
javax.resource.spi.ApplicationServerInternalException:
Unable to get a connection for pool = 'eis/Apps/Apps',
weblogic.common.resourcepool.ResourceUnavailableException:
No resources currently available in pool eis/Apps/Apps to allocate to applications.
Either specify a time period to wait for resources to become available, or increase the size of the pool and retry.. Please make sure that the JCA connection factory and any dependent connection factories have been configured with a sufficient limit for max connections.
Please also make sure that the physical connection to the backend EIS is available and the backend itself is accepting connections. ".
The invoked JCA adapter raised a resource exception.
Please examine the above error message carefully to determine a resolution."
Obviously what is happening is the connection pool maximum is reached (currently 15) and this is throwing the error.
What I need to do is to implement the suggestion of "specifying a time period to wait" and I was hoping someone could tell me how I do this?
I have tried setting the 'Connection Creation Retry Frequency' parameter to 30 seconds which made no difference and also have checked the documentation on "Configuring and Managing JDBC Data Sources for Oracle WebLogic Server".
Does anyone know if this is something that is implemented directly in the BPEL process/composite or in the connection source itself.
Many thanks

Open the jndi : eis/Apps/Apps in /console - config tab - increase the initial and max conn capacity and save it. Retry the scenario

Unable to create new connection using SAP Business One

Hi all,
I am unable to make a connection using the new SAP Business One connetion provided with the 8.8 release of SAP Business One Crystal Report Integration Package.
There are no Companies available to select from. When I try to manually type in the company name, the logon fails. If I then press "Cancel", I get a message that Crystal reports encountered a problem and needs to close. The details of the error refers to the following DLL: crdb_b1.dll.
The connection is successful from another PC that only has the Client installed (and uses the License server on our server, which also contains the databases.)
I have a local installation with my own license server. I am not even able to connect to the database on my local PC.
Please can anyone explain why this isn't working?
Regards,
Rikard

Hi Rikard,
You may get better help if you post your question to the Business One forum. I can' t move your post.
Thank you
Don

Opening multiple reports in Crystal Reports for VS causes database connect limit to be reached. Seems to be no way to force Crystal Reports to close database connection (other than exiting application)

I am working on upgrading an application that has been in use for many years. The application is written in VB6 and I have been tasked with upgrading the current application to Crystal Reports for Visual Studio. I am using Crystal Reports for VS Version 13.0.12.1494. The system's database is a Sybase SQL Anywhere 16 database with an ODBC connection using integrated login. Each of the reports has the database connection set up from within the report. There is only once database server, so each of the reports are pointing to the same DB. The database server is currently installed as a "Personal Server" with a limit of 10 connections.
I have implemented the CR viewer as part of a COM-callable wrapper that exposes a COM interface for VB6 to interact with. Inside of my viewer component is a Winform that embeds the Crystal's Report viewer. The COM interface basically maps the basic Crystal apis to methods that the VB6 can call (i.e., Load Report, Set Field Text, Update SQL Query, etc). This architecture is working as designed and the reports are displaying correctly and responding correctly to changes in queries, etc.
The issue is that after I open 9 reports, the tenth one will respond with an error indicating that the database connection limit has been reached. The database connections used by the reports aren't released until after the application is closed. The application is designed for a secure environment that prohibits the non-administrative user from accessing the systems desktop, so asking the user tor restart the application after 10 reports isn't a viable option.
I have checked and database connection pooling is turned off for the SQL Anywhere 16 driver.
I have been digging on this for a few days and have tried adding code in the FormClosed event to close and dispose of the Report Document as follows:
ReportDocument reportDoc= (ReportDocument) crystalReportViewer1.ReportSource;
reportDoc.Close();
reportDoc.Dispose();
GC.Collect();       // Force garbage collection on disposed items
I have also tried the following (as well as maybe 20 or so other permutations) trying to fix the issue with no success.
ReportDocument reportDoc= (ReportDocument) crystalReportViewer1.ReportSource;
foreach (Table table in reportDoc.Database.Tables)
     table.Dispose();
crystalReportViewer1.ReportSource = null;
reportDoc.Database.Dispose();
reportDoc.Close();
reportDoc.Dispose();
reportDoc = (ReportDocument)crystalReportViewer1.ReportSource;
GC.Collect();       // Force garabe collection on disposed items
Any ideas or suggestions would be greatly appreciated. I have been pulling my hair out on this one!

Hi Ludek,
Thanks so much for the quick reply. Unfortunately I did not have time to work on the reporting project Friday afternoon, but did a quick test this morning with some interesting results. I'm hoping if I describe what I'm doing, you can show me the error of my ways. This is really my first major undertaking with Crystal Reports.
If I simply load the report, then close and dispose, I don't hit the limit of 10 files. Note that I do not logon manually in my code as the logon parameters are all defined within the reports themselves. The logon happens when you actually view the report. Loading the report doesn't seem to actually log in to the DB.
What I did was create a very simple form with a single button that creates the WinForm class which contains the Crystal Viewer. It then loads the report, sets the ReportSource property on the CrystalReportsViewer object contained in the WInForm and shows the report. The report does show correctly, until the 10 reports limit is reached.
The relevant code is shown below. More than I wanted to post, but i want to be as complete and unambiguous as possible.
This code displays the same behavior as my earlier post (after 10 reports we are unable to create another connection to the DB).
// Initial Form that simply has a button
public partial class SlectReport : form
        public SelectReport()
            InitializeComponent();
        private void button1_Click(object sender, EventArgs e)
            ReportDocument rd = new ReportDocument();
            ReportForm report = new ReportForm();
            try
                rd.Load(@"Test.rpt");
                report.ReportSource = rd;
                report.Show();
         catch (Exception ex)
              MessageBox.Show(ex.Message);
// The WinForm containing the Crystal Reports Viewer
    public partial class ReportForm : Form
        public ReportForm()
            InitializeComponent();
        private void Form1_Load(object sender, EventArgs e)
            this.crystalReportViewer1.RefreshReport();
            this.FormClosed += new FormClosedEventHandler(ReportForm_FormClosed);
        void ReportForm_FormClosed(object sender, FormClosedEventArgs e)
            ReportDocument rd;
            rd = (ReportDocument)crystalReportViewer1.ReportSource;
            rd.Close();
            rd.Dispose();
        public object ReportSource
            set { crystalReportViewer1.ReportSource = value; }
Again, any guidance would be greatly appreciated.

Cisco Security Agent unable to close tcp/135 port on Windows hosts

Hello
I've encountered with problem that Cisco Security Agent unable to close port TCP/135 on windows PC (XP or Win7).
I've configured rule module Network Access Control to prevent all client/server connections to port tcp/135.
I've checked my policy using nmap, so this port (TCP/135) during 20 minutes shows as filtered and i can see log in monitor event on CSA MC, during next 20 minutes it show as opened and no log shows. (time not exact, so it maybe 30 minutes or 5,it varies)
Can anyone explain how TCP/135 works and is it possible to close it using CSA?
Thanks in advance

There is another question for the same issue on the forums (see: CSA 6.0.2.145 problem with windows 7 firewall). I wrote:-
"I went ahead and tested this in the lab with winXP and CSA 602-149 (latest). I defined a rule with DENY tcp/135 and ran the nmap and it reports opened (wireshark shows syn-ack to the syn). I changed it to a PRIORITY DENY and now the nmap reports closed (wireshark shows reset to the syn). Via the cli, netstat -an shows the pc listening on tcp/135 & disabling CSA the syn gets the syn-ack response. To me this implies a couple of defect. 1: The DENY should block syn to tcp135 & 2: CSA should not send reset (it should be reset). Is it possible to open a TAC case and put my name (mwinnett) in it and I will open a defect."

I am fed up with Spring and Apple passing me off to one another and neither will fix the problem. I am unable to receive a connection on my phone.

I am fed up with Spring and Apple passing me off to one another and neither will fix the problem. I am unable to receive a connection on my phone.
The internet goes out and I have to reset network setting each and every time. This is only a temporary solution which by the time I release the line with Spring or leave the apple store the issue is back. Sprint indicates that it is a know issue with the Iphone 5 and apple says it is a network issue as Sprint's network is not up to par with the Iphone and can not meet the expectations on the Iphone 5.
I have attached a few picture, as you can see it clearly says I have 5 bars and 3g available but I have no connections what so ever.
This issue affects all data and so I can not send or receive picture messages, use apps, or access the internet. The data goes in and out intermittently and it seems the phone chooses what I can and can't do.
For example I can watch Youtube or Vevo videos but I can not access Facebook or Instagram.
Is anyone else having this issue?
I will soon loose my patience....
I have reset my phone three time and have reset network and other setting mutltiple times.

Tecra A10 - Refurbished - unable to get it connected to my home network

I just got this Tecra A10-104 refurbished Laptop...before I take it back I am asking here just in case theres something I have missed as I am unable to get it connected to my home network.
I am running a Belkin Wireless Router that has 2 main PC's directly connected (LAN), and another PC wirelessly connected.
This is my router: http://www.belkin.com/uk/support/article/?lid=enu&pid=F5D8233uk4&aid=9238&scid=0
All PC's working fine and connected.
Now I'm trying to setup this laptop to connect.
I uninstalled the Vista Business and ussed the XP Pro Product Recovery disc that came with the Tecra.
My WiFi card is: Intel(R) Wireless WiFi Link 5100 (Driver Date: 27/04/2008 - Driver Version: 12.0.0.73)
It sees the network but no matter what i try just won't connect.
What I have done so far (read before suggesting stuff I have already tried):
Reconfigured routers WPS to Shared Key system.
Made sure the wireless adapter has settings set to 20/40hz (auto)
Restarted router, cable modem & laptop several times
Wireless button on side of Laptop is ON.
FN + F8 to enable WIFI (ON) BLUETOOTH (OFF)
Added wireless network to Auto Connect settings along with SSID and passcode end encryption method.
Clicked connect when network appears in network viewer dialogue and retyped passcode.
Not working.
I should add the Laptop has no problems connecting via its Gigabit LAN port.
Anything else I'm missing?
Thanks in advance.
EDIT: Dual post removed.

UPDATE:
The next thing I tried was to reinstall Vista Business from recovery disc to see if this suffered from the same problem.
The wireless connection worked fine on Vista and, despite the updates that I was being offered, worked without needing to update any drivers.
This made me think...so the issue is probably XP DRIVER related.
What I have done now is backup all the driver updates I was told to download by TEMPRO (BIOS & wireless manager updates included).
I think part of the problem is that TEMPRO only works in Vista (not XP) so you are not informed of any updates that may be required if you downgrade to XP straight after purchase (which is what I did).

Unable to get Data Connection on Treo Pro after Flying (Sprint)

I got my Treo Pro a few weeks ago and have really had no issues. It has been a great phone, but I just ran into an issue I cannot explain.
I had to fly from Mpls to Miami and put my phone in "airplane mode" when the flight started. When I landed I took the phone out of "airplane mode" and was able to get voicemail and make calls. However, when I tried to get email or open a browser session the phone kept giving me an error. It was trying to dial #777 to begin a data session (I think) and said it was unable to make a connection. I removed the battery and forced the phone to reboot and everything work just fine.
Someone I traveled with suggested I give it some time to "sync" up with the network, so on the return trip I just let phone continue to try and establish a session for about an hour. After an hour with no email I got frustrated and rebooted the phone... again everything worked just fine. Am I going to need to reboot this phone every time I travel? Is there something I am missing here?
Is anyone else seeing this? Is it a Sprint Issue? Please help. Thanks in advance.

Hello and thank you for using the Palm Help Forums!
That's strange and I've never heard of this issue. I usually don't jump to this method of troubleshooting right away but I do not have any other idea to resolve this issue. Try to do a hard reset on the device. A hard reset will erase all data on the device and restore settings back to default. Be sure to back up all data on a computer to Outlook via Activesync or Windows Mobile Device Center (WMDC). For further information and instructions on hard resets please visit kb.palm.com and look up article number 43146 in the solution id search field.

How to close RFC connection in one script coding

In one script, I am using the REF command to call another 2 scripts and these called scripts shd be run on same C36 ( test system). I shd close RFC connection between these 2 scripts.
That is , once the 1s script over the RFC shd be closed and the user has to give usename and pwd then 2nd script shd run.
I have tried with the following code. But it says RFC is not open
REF ( Y04S_FC_RM_CJ88_112 , Y04S_FC_RM_CJ88_1 , C36_999 ). (when execute this script RFC to C36 will be created and after execution that RFC shd be closed so I included following ABAP code)
ABAP.
data : dest type RFCDEST.
move 'S4_SAPC36999' to dest.
move dest to v_dest.
*--Close the connection before opening it incase it is opened
 call function 'RFC_CONNECTION_CLOSE'
 exporting
 destination = dest
 exceptions
 destination_not_open = 1
 others = 2.
 if sy-subrc <> 0.
 endif.

REF ( Y04S_FC_RM_CJ44_112 , Y04S_FC_RM_CJ44_1 , C36_999 ). (here agagin the RFC will be created and this script will be exectued.)

In one script, I am using the REF command to call another 2 scripts and these called scripts shd be run on same C36 ( test system). I shd close RFC connection between these 2 scripts.
That is , once the 1s script over the RFC shd be closed and the user has to give usename and pwd then 2nd script shd run.
I have tried with the following code. But it says RFC is not open
REF ( Y04S_FC_RM_CJ88_112 , Y04S_FC_RM_CJ88_1 , C36_999 ). (when execute this script RFC to C36 will be created and after execution that RFC shd be closed so I included following ABAP code)
ABAP.
data : dest type RFCDEST.
move 'S4_SAPC36999' to dest.
move dest to v_dest.
*--Close the connection before opening it incase it is opened
 call function 'RFC_CONNECTION_CLOSE'
 exporting
 destination = dest
 exceptions
 destination_not_open = 1
 others = 2.
 if sy-subrc <> 0.
 endif.
 move sy-subrc to v_subrc.
ENDABAP.

Open and close RFC connection with portals...

Hi Experts,
I created a RFC having a query which is taking a long time to execute. So i want to close RFC connection with portals which is via java connector(JCO) before that query and open the connction again after that query.
Please advice is it possible to achieve this. If yes, then how.

Guddan

Hi Guddan,

I guess i will need to understand your requirement a little more in detail, as i understand you have an RFC which has a query within to fetch some data and is taking a long time to do so. In the meantime you don't want to keep the connection open?
My question would be, Is the role of this RFC to only execute the query and fetch the data or does it do something else?
If it does other things and these are independent of the query execution, then you can span a parallel call within the RFC to execute the query and in the meantime the RFC does the other things (or vice versa) hence reducing the overall time taken.
If the sole purpose of this RFC is to execute the query, then you will not be able(i mean to say there is no simple and direct way of doing this) to close the connection after the Query is started and re-establish the connection after its execution, for a simple reason that - how will you know if the query has completed it's execution, so that you can establish the connection back.
Alternate solutions, make this a two way asynchronous call, 1) You invoke the RFC asynchronously and close the connection, the RFC in turn will execute the query and transfer the data to JCO via another RFC call.
If this needs to be a synchronous call, then you will need to optimize the query to its best.
