Database link TCP ports

We installed database link between two Oracle databases. Does anybody know on whitch TCP port it communicate ? I know only about port 1521. Problem is that we have firewall between computers and we need to enable Oracle communication between them.

Thanks,Hans and Devotee have given you the best info so far. I'd like to expand and clarify slightly on their comments.
There is really nothing special about a db-link. It is just another client process, being used by the 'client' database. It uses exactly the same networking pieces as does sqlplus on the same machine. All of the same considerations are there ... tnsnames.ora on the client machine matching up with the listener configuration on the target machine, listener ports, port redirection for establishing the actual server process, etc. I would start by getting a sqlplus connection working. When you have that, you know you have all of your network configuration issues resolved. At that point any issues you have with the dblink will be in the link definition itself.
And as Hans pointed out, databases don't run on port 1521. It is a conceptual mistake to think of the database as "running" on any port. By default the listener uses port 1521 to listen for connection requests. The database knows nothing about that. It is also very easy, and not that uncommon, to configure the listener to use another port instead of or in addition to 1521, so it is also a mistake to treat port 1521 as if it were some immutable value.

Database Link - What ports are used?

I am attempting to create a database link from a very locked down server (Database A) to Database B which is on my internal network.

P6 Web Access connection to MS SQL Server database using TCP Dynamic Ports

Hi,
I am attempting to install P6 Web Access. When I run the installation and do the database configuration I am required to input a port number into the Database Host Port field. I do this and no error is displayed graphically, but I get a connection refused error when I look in the web access log.
"com.microsoft.sqlserver.jdbc.SQLServerException: The TCP/IP connection to the host has failed. java.net.ConnectException: Connection refused: connect "
The dba is running the database on an sql server farm and does not want to apply a static tcp port to the Primavera database as this will interfere with his other databases.
The fact that it appears to be mandatory to input a host database port during database configuration, has me thinking that P6 Web Access requires that the database be set up with a static TCP port? Is this correct?
I searched the documentation about this but came away with nothing...
any help would be truly appreciated.
Andy

At my previous company we experienced a similar issue with P6 Web. Our P6 database was hosted on an Oracle RAC and when configuring the Web connection I was forced to point it to a single RAC server rather then allow it to utilize the cluster. If you have found a resolution to this I would be interested in hearing about it.

Using database-link in view to get around ORA-01031 error

I have been granted select rights on a users table. I am therefore able to select from his table. If however I try create a view against his table I run into the ORA-01031 problem. I have worked around this problem by creating a database-link to myself and then adding that to the view creation and it works. What are the downsides of using the database-link in this way?

The only down side I have been able to identify is that a extra session is created and that the CPU has a little extra work due to the LOOP BACK that takes place. I need to ensure the network is not unnessesarly used and therefore will need to ensure that 127.0.0.1 (local host) is used in the database connection discription. e.g.
create database link my_db_link connect to scott identified by tiger using '(description=(address=(protocol=tcp)(host=127.0.0.1) (Port = 1521) ) (connect_data= (sid=ora10g)))';

Not able to create a database link using the database gateway of oracle 11g

HI,
While trying to create a database link to SQL server from Oracle ,using the database gateway provided with 11g, i am getting the following error while making use of it in selecting columns from tables :
Error starting at line 1 in command:
select * from test1@dblink
Error at Command Line:1 Column:20
Error report:
SQL Error: ORA-28513: internal error in heterogeneous remote agent
ORA-02063: preceding line from DBLINK
These are the steps i have followed for setting up:
1.Ran the set up for the Database gateway.and mentioned the SQL server name and database .ALos set up a listener.
2. Added the following in the Listener.ora of Oraclehome 11/NETWORK/ADMIN:
LISTENER_SQL_FCD =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST =localhost) (PORT = 1541)
SID_LIST_LISTENER_SQL_FCD =
(SID_LIST =
(SID_DESC =
(SID_NAME=dg4msql)
(ORACLE_HOME= D:\app\20537\product\11.1.0\db_3)
(PROGRAM=dg4msql)
3.Added the following in tnsnames.ora inOracle home/NETWORK/ADMIN:
dg4msql=
(DESCRIPTION=
(ADDRESS=(PROTOCOL=tcp)(HOST=localhost)(PORT=1541))
(CONNECT_DATA=(SID=dg4msql))
(HS=OK)
4. Following is the entry in initdg4msql.ora in C:\product\11.1.0\tg_5\dg4msql\admin:
HS_FDS_CONNECT_INFO=10.148.45.242:1433//SalesDemo
HS_FDS_TRACE_LEVEL=DEBUG
HS_FDS_RECOVERY_ACCOUNT=RECOVER
HS_FDS_RECOVERY_PWD=RECOVER
5. Created the database link :
create database link dblink
connect to "sa" identified by "<pswd>"
using 'dg4msql'
On running :select * from test1@dblink i get the following error:
Error starting at line 1 in command:
select * from test1@dblink
Error at Command Line:1 Column:20
Error report:
SQL Error: ORA-28513: internal error in heterogeneous remote agent
ORA-02063: preceding line from DBLINK
Is there any issue with the set or definition that I get the above error?

What is the version of the Oracle database in which you have specified/and use the database link?
If it is for example 10.2.0.3.0 you need to apply the mandatory patch for RDBMS bug 5965763 first before being able to use an 11g gateway. Have a look at MetaLink note 457808.1 for details about this patch.

Ed

Failed to create Database Link in OWB 9.2 for remote SQL Server

Hi,
I have to create Database link for connecting to SQL server in a different machine.I am using OWB 9.2 and XP.

Testing...
Failed.
ORA-12154 TNS:could not resolve service name
*Cause: The service name specified is not defined correctly in the TNSNAMES.ORA file
*Action: Make the following checks and correct the error:
- Verify that a TNSNAMES.ORA file exists on your repository server
in the proper place and is accessible. See the operating
system specific manual for details on the required name and location.
- Check to see that the service name exists in one of the
TNSNAMES.ORA files and add it if necessary.
- Make sure there are no syntax errors in the file.
Particularly look for unmatched parentheses or stray characters.
Any error in a TNSNAMES.ORA file makes it unusable. See
Chapter 4 in the SQL*Net V2 Administrator's Guide. If possible,
regenerate the configuration files using the Oracle Network Manager.
Is there anything wrong in my configuration. Please help me in getting out of this problem.
Thanks in advance
Andy

Hi Mark,
Thanks Mark.I did the changes in the specified .ora file but now it shows a different error message.
The error is

Timeout when using database link connecting to a remote database

Hi,
I have another strange problem. I have two computers A and B. Both have an Oracle database server instance. I manage the one in B (which is my local computer) but not the one in A (which is a computer where I have a user account and an Oracle account but I don't own or manage).
I tried to establish a database link on the database in B pointing to the one in A. This works.
When I try the opposite, that is, establish a database link on the database in A pointing to the one in B I cannot get it work. I can create the database link but then when I try to use it (e.g., by submitting a "SELECT") it blocks for a long time and finally returns "ORA-12535: TNS:operation timed out". I tried to execute telnet from A to B using the port of the Oracle database server in B and it seems that the connection is established. I tried something similar with tnsping but this does not work, as I get again the timeout. I tried deactivating the firewall on my computer B, but it does not work either (besides, the telnet passes through even if I have the firewall activated).
Any idea?
My TNSPING looks like this:
tnsping '(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = <the-target-ip>)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = XE)
I also tried with:
tnsping '(ADDRESS = (PROTOCOL = TCP)(HOST = <the-target-ip>)(PORT = 1521))';
I'm lost... Any ideas are very much appreciated.
Thanks!

From A to B and from B to A can you ping ... post the output surrounded by tags for formatting.
Do the same thing for TNSPING.
What do these computers have in the way of firewalls and antivirus products installed and how are they configured?

Problems in using database link

Hi all,
I have problems in using the following created database link:
Name: fzanalyze
User: fzanalyze
PWD: xxx
Host: fz.domain.com
I get the following error message, if I try to start this select:
select * from tab@fzanalyze;
FEHLER in Zeile 1:
ORA-12154: TNS:Couldn't resolve service name
The problem, the TNS is correct, because I copied the hoststring from the tnsnames.ora. Also I can connect to the database by using the given hostname as follows:
connect fzanalyze/[email protected]
connected
What could be the problem, the I get the tns-Error, although I can connect normal to the database??
Thanks for helping
Dana

Dana,
Unlike Kamal, I don't use SQLNET anymore (isn't it obsolete from 8i+?), so I don't have any sqlnet.ora on my client or server.
I'm not really a sysop, so no clever thoughts behind the following ideas, I just use these for development purposes at home:
IP range at home = 192.168.x.x segment (another router server connects to the internet)
Oracle server computer name = dbserver.seinpost.nl (local address = 192.168.1.110)
instance entry in $TNS_ADMIN/listener.ora @ server:
    (SID_DESC =
      (GLOBAL_DBNAME = inst04.seinpost.nl)
      (ORACLE_HOME = /u01/app/oracle/product/10.1.0/db_1)
      (SID_NAME = inst04)
    )instance entry in $TNS_ADMIN/tnsnames.ora @ server:
INST04.SEINPOST.NL =
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = dbserver.seinpost.nl)(PORT = 1521))
    (CONNECT_DATA =
      (SERVICE_NAME = inst04.seinpost.nl)
)instance entry in tnsnames.ora @ client:
INST04 =
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS =
        (PROTOCOL = TCP)
          (HOST = 192.168.1.110)
            (PORT = 1521)
    (CONNECT_DATA =
      (SERVICE_NAME = inst04.seinpost.nl)
)So again, no sqlnet.ora and as you can see only on my client I use local IP addresses to prevent my client for searching the internet for the non-existing dbserver.seinpost.nl address
Hope this helps,
Michiel

Database link from Oracle to MySQL with the use of unixODBC

Hi,
I have 2 servers.
Server A:
- CentOS_5.1 x386
- MySQL 5.1
- unixODBC
- mysql-connector-odbc
Server B:
- CentOS_5.1 x86_64
- Oracle 11g
- unixODBC
- mysql-connector-odbc
I've configured ODBC, so I am able to do "isql <DSN> oracle oracle -v" sucessfully with "root" and "oracle" user on Oracle server. I've configured listener.ora and tnsnames.ora
I added below lines to listener.ora
SID_LIST_LISTENER=

There is "emp" table in MySQL, from where I can even select with the use of isql command and from this Oracle server.
I would really appreciate some help here.

Database link from Oracle to MySQL

I tried and googled an tried again...but I can't get this to work. So if you can spare a moment, please help me out (or try to ;-) ).
Environment:
The Oracle Developer Days Virtual Box image, so that's 11gR2 EE on OEL. MySQL 5.1.51-community + mysql-connector-odbc-5.1.7-0.i386.rpm
1. Created a database called test in MySQL, with a user "oracle" and a password "123".
2. Created the file /home/oracle/.odbc.ini with as contents:
[ODBC Data Sources]
myodbc5 = MySQL ODBC 5.1.7 Driver DSN
[myodbc5]
DRIVER      = /usr/lib/libmyodbc5.so
DESCRIPTION = MySQL ODBC 5.1.7 Driver DSN
SERVER      = 127.0.0.1
PORT        = 3306
USER        = oracle
PASSWORD    = 123
DATABASE    = test
CHARSET     = latin13. Created the file /home/oracle/app/oracle/product/11.2.0/dbhome_1/hs/admin/initmyodbc5.ora
# HS init parameters

       (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA = (SID=myodbc5))
    (HS=OK)
)5. Added to listener.ora (and restarted it) :
SID_LIST_LISTENER =
(SID_LIST =
    (SID_DESC =
      (ORACLE_HOME = /home/oracle/app/oracle/product/11.2.0/dbhome_1)

      (PROGRAM = dg4odbc)
      (ENVS ="LD_LIBRARY_PATH=$ORACLE_HOME/lib:$ORACLE_HOME/hs/lib:/usr/lib:/lib")
)6. Ran some tests:
a. isql dg4odbc -> Connected!
b. tnsping dg4odbc -> OK
c. lsnrctl status -> Service "myodbc5" has 1 instance(s). Instance "myodbc5", status UNKNOWN, has 1 handler(s) for this service...
d. in SQLPLUS (as system): create public database link mysql connect to "oracle" identified by "123" using 'dg4odbc';
e. select * from test@mysql ("test" is a simple table I created in the MySQL DB) returns
ERROR at line 1:
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:

Some addtional tests I ran:
dltest /usr/local/lib/libodbc.so returns SUCCESS: Loaded /usr/local/lib/libodbc.so
ldd /usr/local/lib/libodbc.so returns
linux-gate.so.1 => (0x00a44000)
libdl.so.2 => /lib/libdl.so.2 (0x00a22000)
libpthread.so.0 => /lib/libpthread.so.0 (0x00110000)
libc.so.6 => /lib/libc.so.6 (0x005b1000)
/lib/ld-linux.so.2 (0x00736000)
So it can find and load the necessary libraries (afaik)..
So any ideas left??

Error using database link

Before creating the link, I went into my init.ora file and made sure the GLOBAL_NAMES entry was false.
I then created a database link using the following:
create public database link cindy_link
connect to system identified by syspswd
using 'PRECISEI';
My link was created, but when I attempt to use it, I get the error:
ORA-02085:database link CINDY_LINK.WORLD connects to PRECISEI.WORLD
Here is the entry from my tnsnames.ora file:
PRECISEI =
(DESCRIPTION =
(ADDRESS_LINK =
(ADDRESS =(PROTOCOL = TCP)(HOST = taurus)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = precisei.world)
Here is the entry from my listener.ora file:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = precisei.world)
(ORACLE_HOME = E:|oracle\ora81)
(SID_NAME = precisei)
(I must admit to not having a full understanding of SID_NAME vs SERVICE_NAME.) I looked in dba_db_links, and my db_link is named CINDY_LINK.WORLD instead of CINDY_LINK.
Do I have a problem in one of my files?
I would really appreciate any help.
Thanks.

Well, I was facing the same problem but corrected it later on. Let me describe the solution is little detail.
You need to check few things before creating db link.
1) db_name and db_domain in init.ora file
2) global_name in listener.ora file
3) service name in tnsnames.ora file.
It seems to me that you have not specified the db_domain in init.ora file. And in that case, you need to follow these steps.
I am considering here that you have database A on server X and database B on server Y.
Go to the first server (server X).
set the global name in init.ora file by following
Global_name=true
db_domain=usa.com
Start and open the database.
connect as system user.
(if your oracle sid is orcl then)
svrmgr30>alter database rename global_name
to orcl.usa.com;
this will set the global_name as specified in init.ora file. Here, your SID is orcl and db_domain is usa.com so global_name will be orcl.usa.com.
svrmgr30>Select * from global_name;
You get the answer like this.
Orcl.usa.com
Now, go to Listener.ora file and change global_name to the new name (orcl.usa.com)
restart the listener.
WE WILL SEE ABOUT THE CHANGES OF TNSNAMES.ORA LITTLE LATER.
Now, go to second server(server Y) and perform the same operation as defined above. i.e. Specify the db_name, db_domain in init.ora file, execute "alter database.." command for setting global_name and edit listener.ora file for new global name.
Once you do all these you need to create service on server 1 to connect to server 2 and on server2 to connect to server1.
Go to server X.
Open tnsnames.ora file and create an entry like this.
P =
(DESCRIPTION =
(ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(Host = IP address of B)(Port= 1521)))
(CONNECT_DATA = (SID = P))
Here, P is global name of P ( at both the places).
Now, go to server Y.
Open tnsnames.ora file and create an entry like this.
Q =
(DESCRIPTION =
(ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(Host = IP address of A)(Port= 1521)))
(CONNECT_DATA = (SID = Q))
Here, Q is global name of Q ( at both the places).
you are all set now.
Create database link between 2 servers now.
Say these are all your settings..
Server X is having database A with global_name orcl.usa.com and server Y is having database B with global_name orcl2.us.com
Now go to server X and create db link to server Y
Create public database link orcl2.us.com using 'orcl2.us.com'
(Note. don't miss to create a service 'orcl2.us.com' in server X's tnsnames.ora file)
And go to server Y and create db link there.
Create public database link orcl.usa.com using 'orcl.usa.com'
(Note. don't miss to create a service 'orcl.usa.com' in server Y's tnsnames.ora file)
hope this helps,
If this doesn't work, feel free to contact me.

ORA-01017 error while using a database link

Hi all,
I have a TNS entry as below
HOME=
(DESCRIPTION=
(ADDRESS=(PROTOCOL=tcp)(HOST=10.66.205.110)(PORT=1521))
(CONNECT_DATA=(SID=HOME))
I have created a database link as
create public database link link92.com using 'HOME'.
This was created successfully and an entry was made in all_db_links table.
However if i try connecting to a table in the remote database...for example
select * from emp@link92;
I am receiving an error ORA-01017(Invalid username passwd).
Would appreciate if somebody could help me out.
Thank you

It is not that the Database Link is "PUBLIC" that makes it use the current username/password.
It is that the Database Link has been created without specifying a " CONNECT TO username IDENTIFIED BY password " that makes the DBLink behave as a "current user database link" using the current username/password to connect to the remote database.
You can have a PUBLIC database link that uses a "CONNECT TO username IDENTIFIED BY password" such that all connections use the same remote username and password.
You can also have "private" (ie not PUBLIC) database link that does not specify a "CONNECT TO username IDENTIFIED BY password" which becomes a "current user [owner] database link".

Database link to SQL Server Init error

Hi all,
i´m tryng to create a dblink between Oracle 10.2.0 in a RHEL4 and a SQL Server.
I can connect using isql but when i try using sqlplus i obtain this error:
SQL> CREATE DATABASE LINK dbl
CONNECT TO "user"
IDENTIFIED BY "pwd"
USING 'hsodbc'; 2 3 4
Enlace con la base de datos creado.
SQL> SELECT * FROM Table_1@dbl;
SELECT * FROM Table_1@dbl
ERROR en línea 1:

Unable to retrieve text of NETWORK/NCR message 65535
ORA-02063: 2 lines precediendo a DBL
This is the error explanantion in Oracle Docs:
I think the problem is the ini file inithsodbc.ora.

I have changed the inithsodbc.ora file including:
HS_FDS_SHAREABLE_NAME =/usr/lib/libodbc.so (I have ODBC installed)

The Database Link is not active

try to be more clear, i'm in lack of ideas in this problem.
I am following guide Oracle Database 2 Day + Data Replication and Integration Guide.
I defined global_names parameter of remote database as true.In the step of "creation database link" i am getting error.(oracle enterprise manager 11g-->schema-->database links-->create)
When i query on remote database(select * from global_name), I got orcl.
So,In "Name" and "Net service name" field i specified orcl.Check radio button "Fixed user." and Username and password of remote database, and i got message "Database Link STRMADMIN.ORCL has been created successfully."
But when i clicked on database link Name i got error, saying that
"The Database Link is not active.ORA-02084: database name is missing a component "
(Both dbs are oracle 11g.)
Please reply.

I think I am confused, "what should be Name and Net Service Name" while creating database link in context of "Database Replication." when global_names parameter is true in both database. I read somewhere "If the value of the GLOBAL_NAMES initialization parameter is TRUE, then the database link must have the same name as the database to which it connects." so what should database link name " should it be remote database name? db_domain?( or outtput of select * from global_name).......
my tnsnames.ora on source db is
ORCL.a.ernet.in =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = a.b.c.d)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = ORCL.a.ernet.in)
when i connect user of remote database(a.b.c.d) from sqlpuls then it is connected.
command which i give : sqlplus remoteUser/[email protected]
