Unable to connect to remote Jrockit instance
Hi,
I Tried configuring Jrockit and integrating weblogic server with it.
I was successfull in monitoring the locally deployed app through integrated weblogic in JRMC 4.0.
Please suggest if the following steps mentioned are proper or not.
1) Installed JRMC 4.0 .
2. Configured in default domain/bin folder of Weblogic server setDomainEnv.cmd as follows:-(Configuring oracle Jrockit in Weblogic since i have to use Jrockit JVM instead of Sun JDK Hot Spot)
set BEA_JAVA_HOME=C:\Program Files\Java\jrmc-4.0.0-1.6.0
set SUN_JAVA_HOME=D:\Oracle\Middleware\jdk160_18
if "%JAVA_VENDOR%"=="Oracle" (
set JAVA_HOME=%BEA_JAVA_HOME%
) else (
if "%JAVA_VENDOR%"=="Sun" (
set JAVA_HOME=%SUN_JAVA_HOME%
) else (
set JAVA_VENDOR=Oracle
set JAVA_HOME=C:\Program Files\Java\jrmc-4.0.0-1.6.0
3.Inturn i modified Java_Options in my local weblogic server startWebLogic.cmd and Remote weblogic server startWebLogic.cmd as follows:-
Local weblogic server startWebLogic.cmd :-
set SAVE_JAVA_OPTIONS="-Djava.rmi.server.hostname=ZSLW521 -Xmanagement:ssl=false,authenticate=false,port=7091,autodiscovery=true"
export JAVA_OPTIONS
Remote weblogic server startWebLogic.cmd :-
set SAVE_JAVA_OPTIONS="-Djava.rmi.server.hostname=ZSLW577 -Xmanagement:ssl=false,authenticate=false,port=7091,autodiscovery=true"
export JAVA_OPTIONS
4. My Oracle Jrockit Start parameters are as follows:-
C:\Program Files\Java\jrmc-4.0.0-1.6.0\bin>java -Xmanagement:port=7091,ssl=false,authenticate=false,autodiscovery=true
and even i am getting the status as follows in command prompt:
[INFO ][mgmnt ] Remote JMX connector started at address zslw577:7091
[INFO ][mgmnt ] Local JMX connector started
[INFO ][mgmnt ] JDP autodiscovery started at address 232.192.1.212:7095
Iin jrmc4.0 UI i am getting JDP (JRockit Discovered protocal)as follows:-
1. Discovered --> JDP --> zslw577:zsl.local and
zslw51
2.But the Problem is that in the tabbed menu
Discovered-->LOACL-->Getting Local JRockit Weblogic server Instance and Not Remote Server Weblogic Server Instance
is when i am trying to establish a connection :-
HOST:zslw521
PORT:7091
1.And testing the connection giving me : Unable to Connect
Even If I want To test The JDP of Remote and Local JVM Instances by right clicking and selecting the option of START CONSOLE
Could not open Management Console for zslw577.zsl.local.

Probably, you'll have more luck on the JRockit forum, I would guess - or perhaps the WebLogic Server forum :)

SSRS 2008 - Unable to connect to remote server
Win2k3 R2 SP2/SQL Server 2008 instance with SSRS/Visual Studio 2008
I installed SQL 2008 and SSRS with native mode default configuration.
All SQL 2008 services are running under "NT Authority\Network Service" account.
When i try to deploy a new report, I get the "Unable to connect to remote server" error.
The deploy operation creates empty folders on the web server (hosted by the SQL Server 2008 service)
for e.g.
my instance name is <machinename>$sql2008. i configured the WebService URL and the Reports Manager URL to port 85
the deploy from VS creates ssrs2008Test folder and a Shared Data Sources folder in the following virtual directory
- Report Manager URL: http://<machinename>:85/Reports_SQL2008/
- Web Service URL: http://<machinename>:85/ReportServer_SQL2008
however these folders are empty w/ no .rdl or .rds file. and i get the "Unable to connect to remote server" error in Visual Studio 2008 when i deploy it.
is there something else i have to tweak in either the SQL Server/SSRS Configuration Manager or the Windows Server Settings(like port settings or group policy) to get the reports to work?
thanks

SharePoint Online - "Unable to connect to remote server"
Hi,
I have a Provider Hosted App which gets the data from a different site collection. Now, when i try to connect to a different site collection, the TokenHelper
class gives me an error - "Unable to connect to remote server".
The error is thrown in the below line:
acsMetadata = webClient.DownloadData(acsMetadataEndpointUrlWithRealm);
The above error is not thrown always. It throws occasionally. I am not getting the reason for this. Could anybody explain what is the problem, please?Hi,
According to your description, my understanding is that the error "Unable to connect to remote server" occurs in the WebClient.DownloadData Function.
As this error throws occasionally, it should be related to the network issue, for a better troubleshooting, I suggest you can check the detailed error message using Fiddler.
Fiddler
Thanks

HTTP Response :500 unable to connect to remote system.
Hi,
I am doing proxy-xi-file scenario, where i am getting this error in sxmb_moni in R/3.
The error reads with red flag:
HTTP Response :500 unable to connect to remote system.
Please tell me what can be the reason.Snehal,
Error: The error message 503 Service unavailable Application stopped! is displayed.
Description: The server is currently unable to handle the request due to a temporary overloading or maintenance of the server. The implication is that this is a temporary condition which will be alleviated after some delay. If known, the length of the delay MAY be indicated in a Retry-After header. If no Retry-After is given, the client SHOULD handle the response as it would for a 500 response.
Note: The existence of the 503 status code does not imply that a server must use it when becoming overloaded. Some servers may wish to simply refuse the connection.
Possible Tips: Because of J2EE application com.sap.aii.af.ms.app not active
Try to (re)start the application using the Visual Administrator Choose Server --> Services --> Deploy --> View on Application or restart the J2EE engine
The problem is that not all J2EE services can be started by the J2EE. i.e Start the Visual Administrator and select Server->Services->Deploy in the tree on the left. On the right-hand side, choose the Runtime tab page. You see a tree in the right window with all applications if you select the APPLICATION radio button. Check if they are running, otherwise choose Start. Usually the J2EE engine starts all services automatically.
Refer SAP Note 803145,807000,791655

Debugger unable to connect to remote process
Hi There,
I am running Jdev on pc and OAS 10g on an unix environment. I followed the step in the doc to set up the remote debugging. However, when I start the remote debugger from jdev, i got the following error message.
Debugger attempting to connect to remote process at ax-portal-www6.dev.ipass.com 4000..
Debugger unable to connect to remote process.
Your help wuld be greatly appreciated.A couple things to try:
1) Verify your jdk version and build bug 4411232
2) Increase your Debugger preferences Connection retries to double the default (especially if multiple apps running, low memory or a slow machine)
Without more specifics on versions, type of debugging or details not much more I can suggest. -
Xcode - Unable to Connect to Remote Repository
I have a mac mini running OS X Server 4 on Yosemite 10.10.1 and I am trying to set up the Xcode server to host my repositories.
On my development machine, when I try to create a project on the remote server, or when I try to push to the server I get the error..
"Unable to Connect to Remote Repository
Could not connect to the remote repository because the server was unreachable. Verify the server is running and try again."
My machine knows that the remote server is there and alive. I am able to add the server in Xcode preferences without any problem.
I can even pull projects that were already on the server. But anything new I cannot push or create.
All the other services I use on the server are working. Hosting a website, Screen sharing and I can SSH into it without any problem.
The strangest part is that when I get the error about being unable to connect, the project I am trying to push actually does show up on the server.
The project shows up on the server in the Repositories. Just my development machine doesn't know it.
Its driving me nuts, can anyone offer any ideas?You said you had SSH access working so this may be a different issue. I was able to ssh into my server only with my admin account which made me think that ssh was working, but it turns out it wasn't for all user accounts. I had the same error message and it turned out I could not ssh into the server with my developer accounts. If I tried to clone a local repository to the server I got the same error, however the repository was actually create, but it was empty. For reasons that don't matter to this discussion I originally setup all my users as "local network users" with no "Home Folder". And that was the problem. Basically ssh won't allow you to login without a home directory.
I had to go back and add a "Home Folder" of "Local Only" for those users who were going to have xCode access. Once the "home" directory was created I could login via ssh on those accounts AND creating and cloning repositories through xCode worked fine. The admin account that I was able to login with already had a home directory and wasn't a network user.
Your issue slightly different even though I got the same error message, so not sure if this will solve your issue or not. But on the off chance that it is the same issue, I figured I would post my solution to my problem. ymmv
P.S. I did turn off websites on my server and haven't turned it back on yet, so not sure if that will be a problem if I turn it back on. -
Cannot open Report Manager URL -- "Unable to Connect to Remote Server"
Hi,
I have recently installed SSRS 2012 on my remote server (Native Mode). I had the default configurations set except for the port has been changed to "8081". I created an Inbound Rule in Firewall to make sure it's enabled.
I'm unable to connect to the report manager locally at all, I got a Domain\username authentication and the credentials are never accepted locally. I tried accessing my report server using the remote server host name and I was successfully logged in,
however, I got a message "Unable to Connect to the remote server".
I checked the log folder and there was no files created for my unsuccessful login.
I've been stumbling with this issue for almost a week, Any ideas or suggestions ?Hi SB User,
Per my understanding that after you change the IP to "8081" then you can't connect to the report server both locally and remotely, right?
Is that mean before you have changed the IP, everything works fine and did you got some pop up window ask for credential when you connect to the report server?
You issue can be caused by many factors, please try to check details information below and do some configurations:
Go to Reporting Services Configuration Manager and change the account to "Network Service" to see if it will works fine.
Change the account to domain account and re-enter the username and password to see if it works fine.
Remove the SSL if configured.
Go to C:\Program Files\Microsoft SQL Server\MSRS11.MSSQLSERVER\Reporting Services\ReportServer\rsreportserver.config
In rsreportserver.config Change the SecureConnectionLevel value to "0":
<Add Key="SecureConnectionLevel" Value="0"/>
Stop and restart the report services instance to see if you can connect to report server.
please also Using IP instead of computer name as the <servername> in the URL to have a test.
If your issue still exists, please try to change the IP to have a test.
If you still have any problem,please fee free to ask.

Unable to connect to the database instance using Enterprise Manager.
I just install Oracle 10gr2 in my computer and after successful installation created a database instance which also install successfully. I then configure the listener using Net Manager and then start the database instance, the listener and dbconsole, everything seems to work fine and checking the status of this services from the command prompt indicates everything started successfully. But when I try to use Enterprise Manager I was directed to the Database Down Page with a message unable to connect to database instance. I try to use startup and perform recovery but every time I log-in to the database an error message comes out:
SQLEXCEPTION
ORA-00604: error occurred at recursive SQL level 1
ORA-12705: Cannot access NLS data files or invalid environment specified.
It seems for Enterprise Manager to connect to the database it needs to access this NLS(National Language Support) data files or specify an environment variable to point to this data files. I am just new to Oracle and I am having difficulty solving this particular problem. Where is this data files located and how do I configure Enterprise Manager to access this NLS data Files?
Any help however small will be highly appreciated.Are you able to connect to the database via SQLPlus?
What Operating System are you using?
Assuming Windows, can you RUN regedit to open Windows Registry and check the value or NLS_LANG when you select
HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\KEY_<your_oracle_home>
Examples of vaules you may find:
1. ENGLISH_UNITED KINGDOM.WE8MSWIN1252
2. AMERICAN_AMERICA.US7ASCII
3. AMERICAN_AMERICA.WE8MSWIN1252
4. FRENCH_FRANCE.WE8MSWIN1252
5. GERMAN_GERMANY.WE8MSWIN1252
If you are not able to connect to SQLPlus, from the command prompt try setting one of the above:
e.g.
D:\>set NLS_LANG=AMERICAN_AMERICA.WE8MSWIN1252
D:\>sqlplus /nolog
SQL>connect sysman/password -

Don't Retire TechnetHi Clayman
Well it makes sense to me that the registry could help, checking the lines in the error code, it appears that the for some reason the server could not stablish a connection, the error states: because the system lacked sufficient buffer space or because a queue
was full.
It seems don't make sence untill you have a look at Socket Class (MSDN article), which say: The Socket class provides a rich set of methods and properties for network communications. The Socket class allows you to perform both synchronous and asynchronous data
transfer using any of the communication protocols listed in the ProtocolType
Checking also the HttpWebRequest Class, we can see the it also relays on Socket Class, as it says by the end of your exception:
[at System.Net.ServicePoint.ConnectSocketInternal(Boolean connectFailure, Socket s4, Socket s6, Socket& socket, IPAddress& address, ConnectSocketState state, IAsyncResult asyncResult, Int32 timeout, Exception& exception)]
I also don't know if you could reboot your machine, but it would be good.
Also I really think its worthy a try, as not much information can befound on this EWS issue.

Cannot connect to remote SSRS instance with SSMS
I recent installed a named instance of SSRS 2005 on a remote server. The server has a side by side install of SSRS 2000 and SSRS 2005, with the SSRS 2005 being a named instance. The server also has SSL and MS Sharepoint Portal Server installed.
When I try and connect to the SSRS 2005 instance with my client install of Mangement Studio, I get the error message:
"The underlying connection was closed: Could not establish a trust relationship for the SSL/TLS secure channel. (System.Web.Services)
Additional Information: The remote certificate is invalid according to the validation procedure. (System)."
Obviously, this is a SLL issue, but, not being a security guru, I have no clue on how to fix this. I do know the certificate is valid, not expired and properly working. Both installs of SSRS are set up using the SSL certificate. Also, I am not connecting to SSIS with Management Studio, as I heard there is a bug connecting to both SSRS and SSIS at the same time.
Anyone have any ideas?
Thanks!!
JeffI know this is an old topic, but I just had a similar issue on SSRS 2008R2 and trying to connect to it with SSMS 2008R2.
The SSRS is using a self-signed certificate. The problem then is how to allow SSMS to accept this untrusted certificate.
I found success with the following steps in the SSMS connection dialogue:
Server Type: Reporting Services
Server name: the exact server name on the certificate does not appear to be required (e.g., "localhost" is fine for a local connection)
On the Options>Connection tab, check
Always Use SSL
On the Options>Additional Connections Parameters
tab, enter the following text:
encrypt=true;trustServerCertificate=true
Click Connect and you should connect without any further certificate trust issues
for that session. Note that these steps must be repeated each time a new connection is made between SSMS and SSRS. -
Dupremove.ncf unable to connect to SQL DB instance
I have ZDM7SP1_IR3a, my inventory database is running as a named instance on SQL2005. I am unable to get the dupremove module to connect to the data base. I keep getting a message:
Trying to (re)connect to the database -> mw_dba

It appears that this module is ignoring the port number provided. Is there a way to get it to accept the port given so that the connection to the database can be made?

Cannot Connect to Remote Named Instance of SQL Server
We have 3x instances of SQL Server 2012 installed on a single remote server - there's the default MSSQLSERVER instance, then \INSTANCE01 and \INSTANCE02. I can remotely connect to the default MSSQLSERVER instance through SSMS, but I cannot connect to
either of the additional named instances (\INSTANCE01 or \INSTANCE02).
For example, if I try to connect to "sql.domain.com", I can successfully access the default instance on the remote server. If I try to connect to "sql.domain.com\INSTANCE01", I get an error stating
"A network-related or instance-specific error occurred while establishing a connection to SQL Server".
HOWEVER - if I try to connect to "sql.domain.com\INSTANCE01, 49301" (where 49301 is the TCP Port for the TCP/IP Protocol for this SQL Server instance), I am able to successfully connect.
This leads me to think that there's a communication issue with the SQL Server Browser service running on the remote SQL Server and my workstation.
The following items have been verified:
SQL Server Browser is running on the remote SQL Server
Windows Firewall has been disabled on the SQL Server
TCP Ports 1433, 1434, 1954, and 49301 have been opened up on the remote destination's firewall
UDP Port 1434 has been opened up on the remote destination's firewall
Thoughts? Did I miss something?Hi brgnewman,
Use computername\instancename to connect to the database engine. Please try again. I think the configuration is OK.
Refer to Connecting from Another Computer:

Thanks.

Oracle 8.0.5 on RH6.0, unable to connect to remote database
Hi Everybody,

is my Oracle running and try to connect to another database on
my site (which is running on HPUX) I got resul ORA-01017 invalid
username/password. Tnsping to this machine is ok, so i have this
in my tnsname.ora When i create dabase link (with user which I
try to use to connect remote database) on my local datbase to
this database then link works sucessfully too. select * from
dual@remote_database Ok. What's wrong ??? Remote database is
Oracle 7.3.4.3 on HPUX. Any difference between SQL*Net of
Oracle7 and 8 ???

Unable to connect to remote JMX
Hi guys,
In our development environment in linux, we are using resin + jdk1.5.
i started my resin server with these options:
-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=8004
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false
It returns "Connection failed" when i tried to connect to it from local.
If i use those options and start it locally, i am able to connect.
Anyone has any ideas what am i missing?
Thanks.

The connection to 192.168.10.143:9958 did not succeed. Would you like to try again?It seems like the JConsole is able to partial connect to the remote JMX service but then fails somewhere in the process.
If I try to connect to a non-JMX listening port on 192.168.10.143 I receive a message in the connection selection dialogue:
Connection failed: non-JRMP server at remote endpointIf I connect to a port that the remote server isn't listening to I do not get the Connection Failed error, it ends up timing out then I sending me back to the New Connection window. -
Unable to connect to remote EJB
