Strange behaviour of polling adapter

Hi All,
I have a strange situation where the database polling is not happening.
Here is my use case
I have a polling db adapter which picks up a record from the table and invokes a procedure on the same database instance with the same connection factory configuration and then commits the data to the AQ . I am using OSB(11.1.7) to achieve this . This worked fine for a while then the issue started appearing . The poller is not being invoked suddenly and with no error log on the all of the servers. I have stopped and activated the db adapter,reset the datasources and restarted the sever but none of them were working . Strangely when i invoke the proxy service from the test console I can see the data in the queue. Assuming there is an issue with the dbadapter this shouldn't work since there is an invocation to the procedure in the same database instance using the same connection factory as that of polling . Can some one please help regarding this if you ever faced such an issue
Thanks..

Hii,
There are scenario where the OSB proxy stops polling the record. Please check the logs to try to figure the exception or you can enable tracing to get the detail.
For time being in order to start polling try to enable and disable the proxy service.
Regards,
Abdul

Windows 8.1 Enterprise Evaluation- Strange behaviour of network adapter

Hello there are discussions and questions around this community about network adapter dropping connection while system is running. But I have found unique problem with my network adapter driver.
I have tried to state my problem as clearly as possible. Please ask if any detail is required.
My network status shows no access on following occasions:
1. On alternate system wakeups.
eg:
a. System boots up
Internet accessible
no problem
b. I put system to sleep(first time) and wake it up
No access to internet !!!
When I check in network and sharing center not even adapter shows in disabled status.(See video from the link given below).
c. Without restarting system or without installing network adapter again, I put system to sleep again and wake it up (2nd time).
Internet accessible
d. I put system to sleep for (3rd time) and wakes it up.
No access to internet!!
If I put system to sleep again and wake it up definitly I get network access.
2. If I switch off the modem before windows shutdown completely or in the process of shutdown, next time when I boot system, even though the modem is switched on before booting the system, No internet access tooltip will be shown on network
sysbol.
Another strange behaviour is on no internet access status, I start installing adapter, and it loads required files and prompt me to click "next" and "click" install.
But the thing is before I go to "next" button, I will get network access as shown in this link
http://youtu.be/sPlXVEiYBeo. Ignore virtualbox adapter. Same behaviour was there when there is no vbox adapter. Same was happening in Windows 8 Pro, but not in windows 7, so that there is no H/W problem I think.
Any idea on how to fix this or any alternate solution ?

Hi,
Firstly, access your network adapter official website to get the proper driver applied to your system.
Then going to Control Panel > Device Manager, right click your adapter > Properties. Under the Power Management tab, make sure "Allow the computer to turn off this device to save power" checkbox unchecked.
If it still persists, try to disable "fast startup" as below steps:
1.In Control Panel, open the Power Options item.
2.Click the Choose what the power buttons do link.
3.Clear the Turn on fast startup (recommended) check box.
4.Click Save Settings.

Strange behaviour from new 2012R2 in old domain

Hi all,
At work (education level), I'm starting to take charge of windows admin, so beiing a noob admin I'm finding strange behaviours that I hope you can help me solve them all :-)
We've one (big) domain with about 5000 computers (workers and students all together), and around 50000 users (again, workers and students all together) setup like this:
DC-DOMAIN-1:
Windows Server 2008R2
Shares NETLOGON and SYSVOL
DC-DOMAIN-2:
Windows Server 2003 R2 x64
Shares CertEnroll, NETLOGON, SMSLOGON, SYSVOL
Checking RootDSE, I see 'domainControllerFunctionaly is Windows 2003' (DC-DOMAIN-2)
So, with this setup, I've noticed these strange behaviours, hope list isn't too big (guess there will be more behaviours but these seemed too odd):
1) On DC-DOMAIN-2, WinServer 2003 eventlog, inside 'Directory Service', I found this warning event ID 1083 (Source NTDS Replication):
Active Directory could not update the following object with changes received from the domain controller at the following network address because Active Directory was busy processing information.
Object:CN=<an user name>, CN=Users, DC=DOMAIN
Usually followed by an information event (eventid 1955) which says:
ctive Directory encountered a write conflict when applying replicated changes to the following object.
Object:
<SAME USER OBJECT THAN PREVIOUS EVENT ID>
Time in seconds:
0
Event log entries preceding this entry will indicate whether or not the update was accepted.
A write conflict can be caused by simultaneous changes to the same object or simultaneous changes to other objects that have attributes referencing this object. This commonly occurs when the object represents a large group with many members, and the functional level of the forest is set to Windows 2000. This conflict triggered additional retries of the update. If the system appears slow, it could be because replication of these changes is occurring.
User Action
Use smaller groups for this operation or raise the functional level to Windows Server 2003.
And having as result that user being blocked in domain.
2) I've added a new print server based on Windows Server 2012R2 (running inside an updated ESX 5.5 with VMXNET3 ethernet adapter as recommended by vmware), and seen in the event viewer these warnings/errors:
At System log:
Error Event ID 5783, Source NETLOGON:
The session setup to the Windows NT or Windows 2000 Domain Controller \\DC-DOMAIN-2.fulldns.name for the domain DOMAIN is not responsive. The current RPC call from Netlogon on \\PRINTSERVER to \\DC-DOMAIN-2.fulldns.name has been cancelled.
I've seen Event ID 5783 with DC-DOMAIN-1 too....
Error Event ID 5719, Source NETLOGON:
This computer was not able to set up a secure session with a domain controller in domain DOMAIN due to the following:
The remote procedure call failed and did not execute.
This may lead to authentication problems. Make sure that
this computer is connected to the network. If the problem persists, please contact your domain administrator.
ADDITIONAL INFO:
If this computer is a domain controller for the specified domain, it sets up the secure session to the primary domain controller emulator in the specified domain. Otherwise, this computer sets up the secure session to any domain controller in the specified domain.
At Microsoft-Windows-TerminalServices-RemoteConnectinoManager/Admin found also this warning:
Warning Event ID 20499 Source TerminalServices-RemoteConnectionManager:
Remote Desktop Services has taken too long to load the user configuration from server \\DC-DOMAIN-2.fulldns.name for user administrator
3) If I try Group Policy Modeling on DC-DOMAIN-1 (server 2008R2), everything works fine, no matter if I try it against DC-DOMAIN-1 or DC-DOMAIN-2, but if I try this from the Server 2012R2 (the one from point 2), I get this:
Simulation against DC-DOMAIN-2: Gets executed, but all GPO show as inaccessible, empty or disabled.
Simulation against DC-DOMAIN-1: Sometimes it gets executed as DC-DOMAIN-2, sometimes I get an error saying query can't be executed.
4) From server 2012R2, I usually manage printing GPO. If I click on the domain root (GPMC, forest, Domains, DOMAIN-NAME-ROOT) right pane, I get a pop up saying:
'A processing error ocurred collecting data using this base domain controller. Please change the base domain controller and try again'
After closing popup, right pane says something like 'DC-DOMAIN-2.fulldns.name' is the baseline domain controller for this domain.
No infrastructure Status information exists for this domain.
Click the Detect Now button below to gather infrastructure status from all of the domain controllers in this domain.
Pressing 'Detect Now' does nothing, and trying to select New Baseline DC shows again same pop up than before.
5) Last, but not least, I've feeling that GPO takes too much to apply. I've found scenarios in which even after executing 'gpupdate /force' correctly on client computer either local or domain admin, I can't see the new changes (gpresult says it has been
updated though). But couldn't find anything on eventlog that informs about problems with GPOs...
For all these strange behaviours I've noticed in last month that I started checking things as sys admin, I believe domain is damaged, or something is wrong there (not just my new server 2012R2, even if it's running inside an ESX, blehh), so please, any hint
on what to check, what to change, what to fix, would be highly appreciated.
Thanks in advance.

Hi Paul,
Honestly, I'm still trying to figure out all broken things reported by tests :( Guess Jesper's suggestion about adding a new 2008 DC to get rid of 2003 and start checking again after that may be best option.
I'll try to summarize list of things I believe are wrong:
running
DCDIAG /V /C /D /E /s:yourdcname > c:\dcdiag.log for every DC, shows different errors. They show things such as:
another domain running here (not administered by us, only relationship is that our users are shared with that domain, nothing else) appear when Printing out pDsInfo (as if they were DC of our domain too, but they do not even share RootDomain). Guess it
may be for a bug old sys admin had when clonning from his 2008R2 template, that forgot to change SID... I already noticed 1 year ago our print server shared SID with those DC, guess there may be more servers sharing SID too :-(
Within Starting test: Replications, I see few messages at Replication Latency Check, such as the one for CN=Schema, CN=Configuration, DC=<ourdomain>:
Latency information for 35 entries in the vector were ignored.
35 were retired Invocations. 0 were either: read-only replicas and are not verifiably latent, or dc's no longer replicating this nc. 0 had no latency information (Win2K DC)
On Services test, I see an
Invalid service type: RpcSs on DC-DOMAIN-3, current value
WIN32_OWN_PROCESS, expected value WIN32_SHARE_PROCESS
On SystemLog, I see LOTS of warnings/errors such as:
A warning event occurred. EventID: 0x80000002
Time Generated: 07/28/2014 08:21:54
(Event String (event log = System) could not be retrieved, error
0x503)
An error event occurred. EventID: 0xC0000003
Time Generated: 07/28/2014 08:22:18
(Event String (event log = System) could not be retrieved, error
0x3afc)
Missing entries on DNS (we've a static DNS)
netdiag.exe /v > c:\netdiag.log Showed again DNS problems such as our primary DNS pointing to all DC, secondary
DNS pointing just to DC with FSMO roles,...
repadmin.exe /showrepl * /verbose /all /intersite > c:\repl.txt Gave no errors, now I must check in detail
if every replica is correct
And finally,
dnslint /ad /s "ip address of your dc" gave more DNS problems:
One or more DNS servers may not be authoritative for the domain
One or more DNS servers did not respond to UDP queries
One or more zone files may have expired
SOA record data was unavailable and/or missing on one or more DNS servers
Sumarizing, guess it will be better to fix DNS problems, promote new 2008R2 DC to get rid of 2003 one, promote domain to 2008 too, check again for messages and relationship with other domain, and then come back here for support if needed
EDIT: Almost forgot to talk about SYSVOL folder. As said before, there are 426 GPO folders inside Policies. Of them, 375 have an inetres.adm files in it (smallest one 1398 KB, almost all of them 2307 or 2707 kb)....

Strange behavior of JDBC Adapter

Hello everybody!
I found a pretty strange behaviour of JDBC Receiver Adapter during problems with network (big thanks to our Basis). According to the status in Adapter Engine, the message wasn't processed. In the database I can see these inserts. However, there are more lines in the XML than lines in the database. So, how it is possible that adapter commits only part of inserts. Logs and settings see below.
My XML includes a SQL_DML statement and a few INSERT statements, each contains many inserts.
It looks like that:
<?xml version="1.0" ?>
<MyMessage>
    <statement>
        <table1 action="SQL_DML">
            <access>here I delete old values</access>
        </table1>
    </statement>
    <statement>
        <table2 action="INSERT">
            <access>some data</access>
        </table2>
    </statement>
    <statement>
        <table3 action="INSERT">
            <access>some data</access>
        </table3>
    </statement>
</MyMessage>

Dear All,
Follow the steps below to resolve the "Connection JDBC_http://sap.com/xi/XI/System is currently not started." issue:
1. Log in to NWA
2. Navigate to Operations -> Systems -> Start & Stop
3. Click on Java Services tab
4. Search the service Service "XPI Adapter: JDBC"
5. Select the service XPI Adapter: JDBC and click on Restart button
With the restart of JDBC Service in NWA, the channels should start working properly

Communication Channel Strange Behaviour

Hi,
We are facing a strange behaviour with communication channel monitoring in RWB for JMS Adapter.
I am sending data from IDoc to JMS. Message is processed successfully inside Integration Engine of PI.Message monitoring in RWB shows status successful.But ,if I monitor communication channel in RWB, under cluster node --> cluster node for Channel 'X' shows status green & in short log - I got an message "JMS message processed successfully at 2009-04-17|05:25:06+0100;JMS & XI identifiers are ID :414d515 & 457e345 respectively".
This information is always updated, when i run my interface & shows the latest three enteries there with information provided above in bold.
But if i see the processing details for Cluster node (Where we usually see the processing of message with its Message ID), there is no entry with Time Stamp & message ID & explanation.
Any idea why such a behaviour?
Thanks,
Venky

Hi,
hmmmm..........strange............
just check if you have multiple server nodes and you are selecting the server node with msg processing and then whether in processing details you are seeing your msgs or not............
also check if the msgs are processed just now or are processed some hours ago - if they are processed some hours ago then may be you do not have their processing details available currently but if they are processed just now, then you should be able to see their processing details..........
if the problem remains, then ask your basis guys to restart your XI J2EE engine and see if you then able to get processing details for your new msgs.........

A strange behaviour throwing Threads via anonymous class technique

Hi friends!
I've noted a strange behaviour executing the next code:
public class ResolAnonimes
     private int value;
     public ResolAnonimes(int value)
          this.value = value;
     public ResolAnonimes myMethod(int nThreads)
          final ResolAnonimes a = this;
          int nThreadsFor = nThreads - 1;
          for( int i=0; i < nThreadsFor; i++)
               new Thread(){
                    public void run()
                            System.out.println(Thread.currentThread().getName() + " has begun processing");
                                 doSomethingWith(a);
                            System.out.println(Thread.currentThread().getName() + " has finished processing");
               }.start();
               this.value++;
          }//for loop
          return a;
     public static void doSomethingWith(ResolAnonimes a)
          System.out.println(a.value);
     public static void main(String Args[])
          ResolAnonimes first = new ResolAnonimes(1);
          ResolAnonimes result = first.myMethod(5);
}When I execute it, that's the output I get:
Thread-0 has begun processing
2
Thread-0 has finished processing
Thread-0 has begun processing
3
Thread-0 has finished processing
Thread-0 has begun processing
4
Thread-0 has finished processing
Thread-0 has begun processing
5
Thread-0 has finished processingWhere's the "1" printed? It doesn't appear! It seems it has thrown only 4 threads, not 5.
Am I doing anything wrong? Is it a bug?
Can you help me, please?
Thank you in advance.

Oh I'm sorry. I was changing the code because of privacy rerasons and I finally didn't type what I want.

Thank you in advance.

APEX Listener and EPG - strange behaviour

Hi
For some years, I've used EPG for APEX but have struggled with performance particularly as I can have up to 150 student developers using at any one time.
I do a fair amount of work using ORDImage and have successfully developed APEX applications to upload image files and display full-size and thumbnail images.
After upgrading to APEX 4.1 (from 4.0), I decided to install APEX Listener standalone.
Before I did so I checked that my applications still worked in 4.1 and they did.
However, just installing APEX Listener but not configuring it (yet) has meant that my image display in a report using a procedure based on wpg_docload.download_file( l_ordimage_image.source.localData ) no longer works in EPG - the images are not displayed.
Configuring APEX Listener and running the same application through that DOES display the images.
So this part of the application works under APEX Listener but not under EPG.
My application also allows users to upload images from APEX_APPLICATION_FILES using standard code. Under APEX Listener after uploading, I'm left with a blank page with a wwv_flow.accept URL although the image does indeed upload. Under EPG it works as expected and I get a success confirmation.
So this part of the application works under EPG but not under APEX Listener.
Has anyone else come across different behaviour depending on the mode of connection?
Thanks

Hi Brian,
it sounds like you have both EPG and APEX Listener running on the same machine, so your problem might result from a port conflict. Note that both services use TCP port 8080 as default.
At least a port conflict would explain the strange behaviour in your case, some things working on one web server and some on the other.
Some parts of your initial post hint to that direction, e.g.
However, just installing APEX Listener but not configuring it (yet) has meant that my image display in a report using a procedure based on >wpg_docload.download_file( l_ordimage_image.source.localData ) no longer works in EPG - the images are not displayed.... because the APEX Listener only interfere with the EPG if it is at least running on the same machine as your database and furthermore, if it is unconfigured in terms of ist database connection, a port conflict might be the only way it could cause anything like that.
However, if you are sure that's not the issue, please check if you see any error in the APEX Listener's log for the following action you performed:
My application also allows users to upload images from APEX_APPLICATION_FILES using standard code. Under APEX Listener after uploading, I'm left with a blank >page with a wwv_flow.accept URL although the image does indeed uploadIf you actually see just a blank screen, something very bad must have happened and you should see some kind of stack trace there.
For further investigations, if necessary, it would be helpful to know how you deployed or started your APEX Listener and which JDK version you use.
For the moment, I still think the port conflict is my best guess.
You could avoid it by either changing the port for EPG (I'd not recommend that if you have other users still using it) or by changing the port for your APEX Listener.

Strange behaviour of Runtime.getRuntime().exec(command)

hello guys,
i wrote a program which executes some commands in commandline (actually tried multiple stuff.)
what did i try?
open "cmd.exe" manually (administrator)
type "echo %PROCESSOR_ARCHITECTURE%" and hit enter, which returns me
"AMD64"
type "java -version" and hit enter, which returns me:
"java version "1.6.0_10-beta"
Java(TM) SE Runtime Environment (build 1.6.0_10-beta-b25)
Java HotSpot(TM) 64-Bit Server VM (build 11.0-b12, mixed mode)"
type "reg query "HKLM\SOFTWARE\7-zip"" returns me:
HKEY_LOCAL_MACHINE\SOFTWARE\7-zip
Path REG_SZ C:\Program Files\7-Zip\
i wrote two functions to execute an command
1) simply calls exec and reads errin and stdout from the process started:
public static String execute(String command) {
          String result = "";
          try {
               // Execute a command
               Process child = Runtime.getRuntime().exec(command);
               // Read from an input stream
               InputStream in = child.getInputStream();
               int c;
               while ((c = in.read()) != -1) {
                    result += ((char) c);
               in.close();
               in = child.getErrorStream();
               while ((c = in.read()) != -1) {
                    result += ((char) c);
               in.close();
          } catch (IOException e) {
          return result;
     }the second function allows me to send multiple commands to the cmd
public static String exec(String[] commands) {
          String line;
          String result = "";
          OutputStream stdin = null;
          InputStream stderr = null;
          InputStream stdout = null;
          // launch EXE and grab stdin/stdout and stderr
          try {
               Process process;
               process = Runtime.getRuntime().exec("cmd.exe");
               stdin = process.getOutputStream();
               stderr = process.getErrorStream();
               stdout = process.getInputStream();
               // "write" the parms into stdin
               for (int i = 0; i < commands.length; i++) {
                    line = commands[i] + "\n";
                    stdin.write(line.getBytes());
                    stdin.flush();
               stdin.close();
               // clean up if any output in stdout
               BufferedReader brCleanUp = new BufferedReader(
                         new InputStreamReader(stdout));
               while ((line = brCleanUp.readLine()) != null) {
                    result += line + "\n";
               brCleanUp.close();
               // clean up if any output in stderr
               brCleanUp = new BufferedReader(new InputStreamReader(stderr));
               while ((line = brCleanUp.readLine()) != null) {
                    result += "ERR: " + line + "\n";
               brCleanUp.close();
          } catch (IOException e) {
               // TODO Auto-generated catch block
               e.printStackTrace();
          return result;
     }so i try to execute the commands from above (yes, i am using \\ and \" in java)
(1) "echo %PROCESSOR_ARCHITECTURE%"
(2) "java -version"
(3) "reg query "HKLM\SOFTWARE\7-zip""
the first function returns me (note that ALL results are different from the stuff above!):
(1) "" <-- empty ?!
(2) java version "1.6.0_11"
Java(TM) SE Runtime Environment (build 1.6.0_11-b03)
Java HotSpot(TM) Client VM (build 11.0-b16, mixed mode, sharing)
(3) ERROR: The system was unable to find the specified registry key or value.
the second function returns me:
(1) x86 <-- huh? i have AMD64
(2) java version "1.6.0_11"
Java(TM) SE Runtime Environment (build 1.6.0_11-b03)
Java HotSpot(TM) Client VM (build 11.0-b16, mixed mode, sharing)
(3) ERROR: The system was unable to find the specified registry key or value.
horray! in this version the java version is correct! processor architecture is not empty but totally incorrect and the reg query is still err.
any help is wellcome
note: i only put stuff here, which returns me strange behaviour, most things are working correct with my functions (using the Runtime.getRuntime().exec(command); code)
note2: "reg query "HKLM\HARDWARE\DESCRIPTION\System\CentralProcessor\0" /t REG_SZ" IS working, so why are "some" queries result in ERR, while they are working if typed by hand in cmd.exe?

ok, i exported a jar file and execute it from cmd:
java -jar myjar.jar
now the output is:
(1) "" if called by version 1, possible to retrieve by version 2 (no clue why!)
(2) "java version "1.6.0_10-beta"
Java(TM) SE Runtime Environment (build 1.6.0_10-beta-b25)
Java HotSpot(TM) 64-Bit Server VM (build 11.0-b12, mixed mode)"
(3) C:\Program Files\7-Zip\
so all three problems are gone! (but its a hard way, as i need both functions and parse a lot of text... :/ )
thanks for the tip, that eclipse changes variables (i really did not knew this one...)

Report S_ALR_87013542 strange behaviour

Hi All,
Report S_ALR_87013542 - Actual/Comm/Total/Plan in COAr crcy - is showing up cross signs in some of the columns.When the cross sign (like any other column value) is clicked the line item detail are sown correctly.
Has anybody encountered this kind of issue before ?
I googled and searched various forums but all in vain.
Please provide inputs to correct this strange behaviour of Report S_ALR_87013542. Thanks!

Dev

Hello Dev,
Did you execute report RKACOR04 for the affected object number and checked if this still happens ?

View Master mode strange behaviour with jpg files

Hy all,
I'm using Aperture, and I'm tweakin a lot the SW to discover all secrets ....
I'm really concerned about a strange behaviour of the SW in view mode.
If I open a jpg file, do not apply ANY modification, and apply the "show master" command (pressing M), there's a subtle behaviour :
*the images get sharper !!!!*
It behaves as if an "edge sharpening" was applied !!!!!!
With _RAW files this thing doesn't happen at all._
Even stranger, if I zoom to full definition (by pressing Z), and toggle between normal view and "show master" view, the immage remains the same !
The effect is not so evident with all images, but sometimes it is !!
Anyway, I expect not to have such kind of things with a professional SW.
With professional cameras and good quality files it's really annoying not to beeing sure what's the REAL content of the jpg image.
Has anyone noted this thing ? Is there a reasonable explanation ?
The only one I tried to figure out is the following : may be Aperture applies some kind of resampling algorithm with jpg files (bicubic, bilinear, etc).
May be this resampling is not applied with 100% magnification, as weel as with raw files.
But it's only my guessing. Now, I'm tweaking other viewers and other SW to understand what's the real jpg image stored in the file : the blurer one form normal view or the sharper one with "show master" mode.
I stress once again : of course, the jpg file I'm talking about have no settings at all, just imported and toggled with M button.
Thanks in advance.
Regards,
Enzo

Hy,
I'm afraid I'm not been clear.
The problem is this :
1) jpg image opened in normal view mode, no zoom, (no quick preview, of course) : image with a certain amount of blour
2) jpg image opened in show master mode, no zoom, (no quick previre, of course) : image SHARPER with respect with the previous.
No edit applied from import, so "show master" command shouln't apply any change in rendering, should it ?
The only thing I said on 100% view is that such difference (between normal mode e show mastermode) is not present with 100% magnification.
That was the issue.

Strange behaviour: two servers on the same port

Hi!
I hope this is the right section for this post. I need help about a strange behaviour involving a ServerSocket.
For my thesis I need to write a program that receives data from a pre-existing DSMS client, filters them and then sends them to a pre-existing DSMS server. And here is my problem: if I try to create a ServerSocket on the same port of the DSMS server, my program throws no exception, and the servers seem running on the same port. This is a behaviour that I'd like to avoid, but I cannot understand what the problem is. Can you help me?
The source code of the DSMS server can be found here (it's written in C++): http://infolab.stanford.edu/stream/code/stream-0.6.0.tar.gz
The source code of my server class, instead, is this one:
import java.io.*;
import java.net.*;
public class ThreadGenerator {
     private ServerSocket server;
     public void connect(String servPort, String cHost, String cPort) {
          try {
               server = new ServerSocket(servPort);
               System.out.println("SERVER running on port "+servPort);
          } catch (BindException e) {
               System.out.println("Address already in use!");
          } catch (Exception e) {
               System.err.println(e);
          try {
               while(true){
                    Socket client = server.accept();
                    StreamThread T = new StreamThread(client, cHost, cPort);
                    T.start();
          } catch (EOFException e) {
               System.out.println("Server closed connection!");
          } catch (Exception e) {
               System.err.println(e);
}I'm programming on Mac OSX Tiger, with Java 1.5.0.
Thanks in advance for your help.

The problem is still happening to me, I tried in this very moment. The code I'm using is the one I posted, and the second server is the one that I linked. I don't think there's anything else to add.
If you're sure that the problem is not in my code, then it means that it is in the linked server, which partially solves the problem. But I'd like to know, if it's possibile, if there is any other way to check if the port is already in use.

Cursor shows strange behaviour in 10.9.5

HI,
I'm using a 15" MBPr late 2013, i7, 16 GB RAM, 1 TB SSD, running on 10.9.5. Lately I registered a very strange behaviour of the cursor when using the built in trackpad. If hovering over one of the symbols in the bar at the upper right corner of the screen and then moving the cursor downward, the menu of the symbol on the right of the cursor pops up (not the one the cursor ist pointing on).
For example: the symbol for WiFi is located left from the one regulating the volume. When hovering over WiFi and moving downwards to activate/deactivate it, the volume-controle pops up ! If I want to use the WiFi, I have to hover over the symbol for bluetooth-connectivity instead....
Any idea whats happening here ?
Help is very much appreciated !
MIchael

OK, found the solution by myself. The reason seemed to be related to the resolution of the display. Changed it to another one (no matter which one), waited for the display to change and the changed the res back to optimal for display.
The cursor now works fine and exactly....
Really weird.

Stopping DB-Polling-Adapter when failure in mediator

Hi
I have a DB-Polling-Adapter that posts data directly to a mediator. When data is readed mediator does a logical delete, e.g 2 for field readstatus. So during reading readstatus is 9 and before 1.
When a failure happens in mediator (during xsl-transformation) mediator throws failure back to DB-Polling-Adapter. The problem is now that state of readingstatus is still 9 and after each polling sequence adaptor reads and posts same data again and the failure happens also.
Is there any posibility to send failure into error hospital and to set readstatus to 2, so that adapter doesn't poll the same data on and on? Catching mediator fault in fault-policies doesn't work.
I found two solutions: 1. Send data from Polling-Adapter to BPEL, 2. Sematron validation but it doesn't cover all posible failures.
Example failure during transformaiton:
ORAMED-03303:[Unexpected exception in case execution]Unexpected exception in request response operation "execute" on reference "Convert_JDE-to-Common". Possible Fix:Check whether the reference service is properly configured and running or look at exception for analysing the reason or contact oracle support. Cause:oracle.tip.mediator.infra.exception.MediatorException: ORAMED-01201:[Error in transform operation]Error occurred while transforming payload using "xsl/F0006Collection_To_ProjectsCollection.xsl" for target part "reply".Possible Fix:Review the XSL or source payload. Either the XSL defined does not match with the payload or payload is invalid
Thx a lot for help.
Pascal

Issue solved.
Setting jca.retry.count=unlimited causes the adapter to behave as we want.
We had set jca.retry.count = 1 on the mistaken understanding that this related only to a failure to query/poll the database, and that sequence number was updated in a separate context that needed a global transaction to coordinate/rollback.
We don’t even need to propagate our global transaction from polling adapter to bpel component since all our writes happen in an OSB transaction; Our bpel just (re)throws a fault back to the polling adapter which is enough to trigger retry.

Strange behaviour in Mail

I have ongoing strange behaviour with Mail in Mountain Lion on a MacBook Pro.
As well as randomly and intermitttently dropping connections to my various mail servers, I also, randomly and intermittently, fail to get to Print, or to create a new Mailbox, or to Quit. I just get a beep.
Have to quit Mail - sometimes forcibly, and restart it.
Mail will not automatically reconnect to servers after a Sleep , or moving to a differnt location.
None of this was happenning on an older MacBook, but I was running 10.7 on that machine.
Had to upgrade machine to allow upgrade to Mountain Lion. Not sure which is responsible - new MB PRo , or 10.8?!
Do I really have to re-install OSX just to reinstall Mail?
Any other pointers/hints very welcome.
Thanks

Please follow these directions to delete the Mail "sandbox" folder.
Back up all data.
Triple-click the line below on this page to select it:
~/Library/Containers/com.apple.mail
Right-click or control-click the highlighted line and select
Services ▹ Reveal
from the contextual menu.* A Finder window should open with a folder named "com.apple.mail" selected. If it does, move the selected folder — not just its contents — to the Desktop. Leave the Finder window open for now.
Log out and log back in. Launch Mail and test. If the problem is resolved, you may have to recreate some of your Mail settings. You can then delete the folder you moved and close the Finder window. If you still have the problem, quit Mail again and put the folder back where it was, overwriting the one that may have been created in its place. Post your results.
Caution: If you change any of the contents of the sandbox, but leave the folder itself in place, Mail may crash or not launch at all. Deleting the whole sandbox will cause it to be rebuilt automatically.
*If you don't see the contextual menu item, copy the selected text to the Clipboard (command-C). In the Finder, select
Go ▹ Go to Folder...
from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.

Strange Behaviour into Runtime Workbench

Hi all,
I have a question for us.
Into our system PI 7.1 we have a strange behaviour in Runtime Workbench - Message Monitoring.
When I choose for the fiel "FROM" the value "Database" I obtain the list of software component that I find the value "Integration Server".
But when I choose the value "Database (Overview)" the value "Integration Server" into list of software component doesn't exist.
Why Do the system have this behaviour?
best regards,
Davide Bruno

Hey,
The old way of seeing msg use - the db option... In Pi 71 the db overiew options gives you an aggregated view of ur messages. this is very helpful in tracking repeated failures, anylysing the types of failures etc...The "strange" view is actually a pretty neat tool... We used to do this in excel sheets after dowloading the report from sxmb_moni..
regards,
Arvind R
