Web Application not able to connect to BO when firewall is ON on BO server

My Business Objects Enterprise (R3) is installed on Windows Server 2008 R2. On the server firewall is ON. I have opened port 6400 on the BO server. But, whenever web application from other machine tries to get data from BO, it displays error message. Are there any other ports which need to be opened to have successful connection. Please help.

Hi,
you have to open your Web Port. If you installed with Tomcat you have to open TCP Port 8080
If you installed with WACS you have to open port TCP 80 and TCP 6405.
But i would recommend disabling the Windows FW.

database_version:11.2.0.3
please let me konw how to connect to the sql developer.
Did you perhaps do a custom install? The DB software includes a version of sql developer and, by default, installs it in the sqldeveloper folder of the DB_HOME. Does that folder have sql developer in it?
I suggest that you NOT use the version of sql developer that ships with the database. That version will NOT be the current version.
Download the current version of SQL Developer, unzip it into a new folder and create a desktop icon for it.
http://www.oracle.com/technetwork/developer-tools/sql-developer/downloads/index.html
The current version includes many, many bug fixes from that earlier DB version and you will have far fewer probems with it.

Not able to connect to Oracle EBS from host Windows 7

Hi, I have installed oracle EBS version 12.1.1 (32 bit) on OEL ver 6.3 (32 bit). I have installed Linux on Oracle VM virtualbox ver 4.1.16.
I am having host OS as Windows 7 home on my laptop.
While setting up the Network in Oracle VM virtualbox, I have set "attached to" as 'Host Only Adapter'.
I am able to connect to oracle EBS from the client server(linux) using Firefox browser. Both the services(database, Application) are starting & stopping without any problem.
I have entered following setting in C:\Windows\System32\drivers\etc\hosts file.
192.168.56.101 linux.server
IP address of Linux OS is 192.168.56.101
Please help in resolving the issue.
Thanks!

I am getting error as "Internet Explorer cannot display the webpage" on IE ver 9, when accessing from host machine. On Firefox (ver 12), the error is coming as "The connection has timed out. The server at linux.server is taking too long to respond."
The firewall on the server has been disabled already.
I am not able to ping the server IP address or hostname.domainname from client. Following error comes while pinging -

Not able to connect with Oracle server through VBScript without DSN

Hi
I have both Oracle9i and Oracle10g clients installed with local system.
I am able to connect to Oracle Database 11g Enterprise edition server though sqlplus through command prompt and also through AQT without any error.
As the server has lots of database ,whenever I connect to a particular database through sqlplus from command prompt,I connect as below
C:>sqlplus username/password@service_name
and it gets connected without any error.
When I am trying to connect the same database through VB Script,I am getting ORA-12560 TNS:Protocol Adaptor Error.
Below is the connection string I am using:
Database_String = "SERVER=xxxx.vvvn.Com;Driver={Oracle in OraHome92};DATABASE=service_name;user id=userid; password=passowrd"
I have installed a Oracle10g server in my local system and tried to connect the same way and I was successfully ,but its not working when the server is running remotely.
Does it make any difference with the version of driver being used ?Should I need to modify my connection string anyway.
Please help me as to identify the issue.Thank you very much in advance.
Regards
Sahina

But,When I am testing <b>mdmsearch</b> webservice with correct repository,port,mdm server details with other required parametes as mentioned in the blog. I am getting the follwing error.
Problem while connecting to MDM repository "MyRep" on server "myserver" at port "2311". Maybe the Repository-Information has not been set correctly at the requested query!
To confirm the connection parameters,I wrote sample java program using mdm java api and run from the was server and i am able to connect to the same.
Is there other sca files need to be deployed on WAS to work with sp4 standard web services.

Not able to connect to oracle 11g using toad9.6

Hey...
I installed 11g on Win7- 64 bit. I'm able to connect to DB using Sql*plus and cmd prompt but when i try to connect through toad, it says no client installed.
I installed 11g with "Desktop class" option.
any suggestions ???

Hi,
1. If you have installed db and toad on the same machine, then the ORACLE_HOME of the database can be used as client.
2. But if you have installed Database on machine1 and you try to connect from laptop1 then on laptop1 client must be installed (to allow TNS communication).
In case 1 above, check installed clients in the window (Session -> New Connection) on TOAD and make sure it is not red. And define TNSNAMES.ORA in the same oracle home listed in installed clients.
In case 2 above, you must have to install a client to allow the communucation between toad and server.
Thanks

Not able to connect remote oracle database over VPN

I can not connect remote oracle database over VPN. tnsping is ok and it shows the server information of remote database. i can also telnet the 1521 port of remote database server. I can connect the same server when it is located in the same LAN. Please help me out this is very urgent.

First, this is a forum of volunteers. There is no "urgent" here.
"Urgent" means one of two things -
1) people are dying, or
2) you have a customer-facing, revenue-producing production system that is down.
(And to get some perspective on the second case, keep the first in mind.)
For the first, you call whatever civil emergency service seems appropriate.
For the second, you open an SR with Oracle - which requires a paid-up support contract. For *them* to consider your problem "urgent", you will need to demonstrate that your problem falls under item #2. I seriously doubt your problem fits that criteria.
You don't have a support contract? Now you know the exact dollar figure that your company places on the data.
That said, you need to understand a few things about your specific problem,
First, port 1521 is only used by the listener to accept a connection request. Once it gets that request (and finds that it is for a service (sid) that it knows about, it will fork a server process and tell the requesting client that it can communicate with that server process over some other port .. a randomly chosen port number in the "high" range. It could be your vpn is blocking that other port, whereas your internal firewall is not.
But this is just an educated guess since I cannot find "can not connect remote oracle database over VPN" in any error message manual. If you had mentioned the VPN along with an actual oracle error message we could be much more precise in our diagnoses and recommendations.
---- edit 22 Sep
It occurred to me that I just assumed you were using the same client machine in both cases ... a laptop that you use both at work (local network) and home (vpn). If that assumption is false, there are probably problems with your tns setup on the home (vpn) machine.
But again, it would be much easier to help if you gave us an actual error message.

Not able to connect to oracle 11g database source through OBI Server

Hi,
I am having an issue regarding the database connectivity.
Iam unable to connect to the oracle 11g database through OBI server. However its connecting through SQL Plus with same username/password@hoststring. Its giving the error as :
[nQSError: 17001]Oracle Error code:1017,message:ORA-01017: invalid username/password; logon denied at OCI call OCILogon
[nQSError: 17014]Could not connect to Oracle database.
Please help me out in resolving the issue.

If it's working in one place and not the other then it's obviously not an OBIEE problem.
Are you typing it in right??
Do you have multiple tnsnames.ora files pointing to different databases, maybe sqlplus is picking up one and toad & OBIEE the other and so the username/pw is wrong for that database?
There's a limited amount that can be said to help, as the error is 100% clear what the problem is :) it's just working out whether you're connecting to the database that you think you are connecting to, and then whether the username & PW you're entering is correct for that DB.
BTW OBIEE 10.1.3.4 is supported with 11g, and we're using it without problem here.
