Networking And Gateways :: Oracle Database Not Connect From Outside LAN Via Static IP
Nov 17, 2011
I have created two database one for production and another one for test.I created both database in shared_server mode(by using dbca),after than I did not change anything.My problem is when i connect to test database from outside lan through static ip its working well,but when i connect to production database which is not connected. I checked and compared two databases,then I find there are some changes in dispatcher and mts_ dispatcher parameters.And I used this query to check the shared_server status,
ie.select * from v$shared_server,
the output of this query is attached with this post.

I had a query related to call_form function in forms 6i.How can I call a particular form via static ip(outside LAN),but the actual forms are stored in a server called "MAIN_SERVER" which resides in internal LAN domain.That is I have stored location of all my forms path(fmx)in my database table called "FORMS_LOCATION" in the MAIN_SERVER system under the directory "FORMS".From here only users can call all the forms by call_form function.To understand see the example below,
In the table FORMS_LOCATION,there is a column call "forms_path" which holds the value like,
//MAIN_SERVER/FORMS/EMPLOYEE.FMX;
(server_name,foldername,form_name)
In application the call_form just uses the column "forms_path" to call the form.like CALL_FORM("forms_path",no_hide) this statement will call the form from the main_server.
Here 1.MAIN_SERVER is the name of the server system where forms fmx is actually stored under the folder name "FORMS".When the users access the particular form the call_form function call the form from the MAIN_SERVER.Now there are no problem inside the LAN.Incase if I access the database and call the form outside LAN via internet through STATIC IP what happened was database was connected but call_form function failed and not calling the form because which does not know the MAIN_SERVER/FORMS/ path.
Because my user want to access the form outside lan via internet,so I tried replacing the above statement like //192.54.67.98/FORMS/EMPLOYEE.FMX' with static ip in the prefix instead of local server called MAIN_SERVER.But its not working again.How can I do this?.

I installed Oracle Express on my Windows 2003 Enterprise server. And right off the bat I cannot connect to it via command line. I have googled and read many sites, but am still getting the same error, no matter what I do. I am newbie again (was a DBA in 1990...when I used to have the same error and fix it in seconds...not sure why this problem still lingers in Oracle) so most likely I am overlooking something. Below are my tnsnames.ora and liserner.ora files
tnsnames.ora
XE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = myservername.domainname.com)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = XE)
)
)
[code]....
# This file is actually generated by netca. But if customers choose to
# install "Software Only", this file wont exist and without the native
# authentication, they will not be able to connect to the database on NT.
SQLNET.AUTHENTICATION_SERVICES = (NTS)

I'm trying to connect from Oracle 11g (11.2.0.1.0) to Sybase Adaptive Server Anywhere (9.0.2.3527). My Oracle environment is running on Linux Centos 5.3, the sybase database runs on a Windows Server.
All my attempts have failed so far - both through Oracle Database Gateway for Sybase and via Oracle Database Gateway for ODBC in combination with freeTDS. Using either way I'm ending up with apparently the same error:
ASA Error -611: Transact-SQL feature not supported
When I use db link created via dg4sybs (Oracle Database Gateway for Sybase) I get this:
SQL> SELECT * FROM aaa@hvx;
SELECT * FROM aaa@hvx
*
ERROR at line 1:
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
[code]....
When I use db link created via dg4odbc (Oracle Database Gateway for ODBC) and freeTDS driver I get this:
SQL> SELECT * FROM aaa@hvx1;
SELECT * FROM aaa@hvx1
*
ERROR at line 1:
ORA-28511: lost RPC connection to heterogeneous remote agent using
SID=ORA-28511: lost RPC connection to heterogeneous remote agent using
[code]....
It seems both drivers use Transact-SQL instructions which are then denied by ASA. I'm not familiar with Sybase products at all, but as far as what my googling revealed the Transact-SQL is only supported in Adaptive Server Enterprise (enterprise-class version of Sybase's database). I couldn't figure out if there's a way how to disable Transact-SQL in the driver configuration. how to connect from Oracle (10g or 11g) to Sybase Adaptive Server Anywhere?

I was trying to connect to SQL server from Oracle using Oracle heterogeneous services (HS).But I found that I do not have HS installed on my system. It was mentioned in Oracle website that we need to run 'caths.sql' script under the path $ORACLE_HOME/rdbms/admin.
But I do not have any such folder(rdbms) in my $ORACLE_HOME.What does it mean? And how can I install HS alone on my system(Since I already have oracle)

I would like to implement connect time fail over from my JDBC thin client. The client will try to first connect with dedicated connection mode, if the connection time crosses more than two seconds, then connection will be opened with shared mode. To implement this, I have put the following connection string in my JDBC URL. I am able to connect to database with this URL, however it seems fail over does not work. Is it because, my database listener is not configured with dynamic service registration. If I implement the dynamic service registration, is fail over going to work? Note, I want to fail over in the same database instance but with different listener.
(DESCRIPTION_LIST =
(FAILOVER = TRUE)
(LOAD_BALANCE = FALSE)

I have a really strange problem connecting from a new client to an Oracle server, here are the points :
- There is no problem with DB server and its listener and all that as I am able to connect from other clients
- I have installed the oraclient on this machine ( it is a XP machine ) and copy/pasted the TNSNAMES.ORA from one of those correct PCs here and when I do a TNSPING is returns OK
- even when I open oracle net manager I see the TNS entries in there and when I test a connection thru it is says successfull
- BUT WHEN I USE SQL+ or TOAD or ODBC ( any of these) trying to make a connection using the exact same TNS entries it returns :
"ORA-12154: TNS:could not resolve the connect identifier specified"
- I have tried with both IP and Host name but no luck
- TNSNames.Ora and sqlnet.ora both are located here : oracleproduct10.2.0client_1NETWORKADMIN
- there is just one oracle home
- I have already uninstalled/installed oracle client
- These lines are included in Sqlnet.ora :
SQLNET.AUTHENTICATION_SERVICES= (NTS) NAMES.DIRECTORY_PATH= (TNSNAMES)
I marked those entries in Sqlnet.ora and that made no diff in result, another thing : if I use easy connect method : sqlplus scott/tiger@<Servername>:1521/ORCL it does connect but using TNSNames still I can not get connected. so strange!!, seems somehow the TNS file even is not being picked or looked at !

I have a database up and running (including listener) on machine A. From that machine, everything seems fine. However, when I try to connect to it from another machine (say, machine B) on the network, the connection cannot be established (exact message: connection to database failed: The Network adapter cannot establish the connection).
I can successfully ping machine A from machine B. The machine A db is a default install (ORCL).
Is it possible the DB listener is not configured properly to connect to remote clients? On machine B, I have oracle tools such as SQLPLUS, Oracle Net Manager, and Net Configuration Assistant.

We want to configure HSODBC on HP-UX 11.23 for Oracle Database 10g R2 in order to establish a DB link from Oracle to Netezza.We have installed the ODBC Drivers too..Currently we have not done any configurations and we go via an AIX box to establish a link.We want to get rid of the AIX box and instead establish directl link towards netezza from HP-UX Box.
Does Oracle support have some guidelines or steps to setup HSODBC on Oracle database 10g r2 residing on HP-UX 11.23 towards Netezza?
