Currently we are loading data from oracle to sql server through oracle 11g gateway. during running scripts most of the queries takes a long time to complete. Because of this performance issue, we want to configure oracle golden gate to move data from oracle to sqlserver. whats the difference between oracle gateway & oracle golden gate? both are performing same functionality?
View 1 RepliesImplemented the Golden Gate replication tool? In particular, to replicate data from Oracle to Sybase?
No details are needed, just a quick nod indicating "yes, it has been done successfully".
Below questions are swirling in my mind while doing some research on Golden gate setup and replication
1) Can we put any time delay between source and target, so that the replication data will be applied after some set of time?
2) If I setup the Golden Gate between Oracle as source and SQL server as destination, then how the core of procedures/views/functions/packages will be replicated to SQL server target?
i.e. is only data replicates between the DBs or the other procedures/views/packages.. etc will also be replicated? If not,then do we need the manual involvement to replicate them?
3) Is it possible to replicate the schemas within the same DB using golden gate?
i.e. if TOOLS DB is shaving schemas A and B, can I replicate the A objects to B schema within the same DB TOOLS?
I am trying to configure Golden Gate but i am running into the following errors while configuring. Given below is the contents of the configuration.

I was planning to a production cut over from Aix to linux .I thought GG as an option so that i can have two DBs run parallel and replicate and do a cutover to linux during the change window.
Now the problem i see is that only half the tables have primary key.. so I THINK golden gate cannot be used an an option.
I want to learn Golden gate from the scratch.
1) Link for downloading golden gate software. I want to use it on oracle 11g on linux (X86). ( I have downloaded fbo_ggs_Linux_x64_ora11g_64bit.zip from oracle.com size 89mb but I'm not sure whether this is the actual version or not!)
2) Easy ,step by step guide to install the software.
3) Documents/link for performing basic operation.
I was trying to test out the bidirectional replication using golden gate 11g . while doing some tests i did find out there are inconsistency in the database.
Scenario:
Database 11gee,Goldengate11g.
Set up a bidirectional replication replication it works fine until i hit the below scenario. I updated 1 record in the source database then i updated same record in the target database . Now i issued commit one by one on both the src/target. Now checking the record in src/target have different values. src containing the value which was committed in target and vice versa in target. leading to data integrity.
How can we resolve the above issues i have tried different options but nothing seems to work till now.

What is the stream's "tag" equivalent in Golden gate ?My tables are already in GG replication, but i want to do few insert in to source which i dont want to replicate to target.

Secondly if my oracle is on linux, can i configure the gateway on a seperate windows machine(that will connect to linux oracle and ms sql server) as i have found the gateway installation setup only for windows version.
We are having oracle 9i as database and migrating to sql server 2008. Our oracle 9i database connects to another oracle databases and these databases are having different oracle version(9.2.0.8.0, 9.2.0.7.0,10.2.0.5.0,11.2.0.2.0,9.2.0.6.0,10.2.0.4.0,8.1.7.4.0 )
I do have two queries :
1) how to connect from Sql server 2008 R2 to different Oracle databases
2) How will other oracle databases connect to Sql server 2008 R2 database
connecting two oracle database in two different server.I installed Oracle 10g XE in both system.Both system act as Server.I need to connect both server using database link concept.
how to use the tnsnames,ora and listener.ora file for connecting both system.
where can i download the oracle gateway for sql server? i can't find the download web site .

I am trying to connect from Oracle 10G to a SQL Server database. I have looked at the manual and i will admit that i am finding the documentation quite difficult to follow. There seems to be several options to use but none of the documentation describe how each option works.
As an example, i have been given the following information on the database i need to connect to (i.e. the SQL Server database)
- Username
- Password
- Database Name [lets assume the database name is data_extract]
To connect the above i made the following changes
$ORACLE_HOME/hs/admin/inithsodbc.ora
---------------------------------------
HS_FDS_CONNECT_INFO = data_extract
HS_FDS_TRACE_LEVEL = 0
$ORACLE_HOME/network/admin/tnsnames.ora
---------------------------------------
sqlserver.db =

[code]....
Note: In listener.ora, i only added the last SID_DESC entry. I then went on and created the database link as shown below
create database link sqlservdb using 'sqlserver.db';
When i try to access a table i get the following error
sqlplus> select * from TESTTABLE@sqlservdb;
select * from TESTTABLE@sqlservdb

ERROR at line 1:
ORA-28545: error diagnosed by Net8 when connecting to an agent
Unable to retrieve text of NETWORK/NCR message 65535
ORA-02063: preceding 2 lines from ORASQLSERVER
A couple of things i am not sure of:
- Where do i specify the username and password to access the sql server from the oracle db to the sql server db
- Having read around on the internet, i can see some people refering to a DSN datasource. I am told that the information that i have is all i need. Is this correct or do i need something else?
- The sid i specified in inithsodbc.ora and tnsnames.ora is actually the sql server database. Is this correct?
I have 9i RDBMS Software and RHEL 4. I want to install a Oracle Names server. I install RDBMS.But Where I run netmgr and want to configure and start Oname server it says.
$ORACLE_HOME/bin/names file not exists.
How Can I configure OracleNames Server using Oracle 9i On Linux.
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)
how can i run dml statement on the oracle transparent gateway for sql server ,such as insert ,update,delete.
View 4 Replies View RelatedWe got a big problem that we have a db link to connect to sql server(big 5).
In original setting, there is no Chinese characters in the data. We simply grab the data from sql server and do not have any issue. But now we have data with Big5. When we import the data into our Oracle DB, which uses UTF8, all the text becomes "?
Changing character set in DB is not possible. We need to convert the text into unicode format, or allow oracle/sql server to convert it automatically.

For using replication in our production, here i am testing golden gate as replication tool. I tested all scenario in Uni direction ( source to destination). Now have to test replication with DDL support in Bi-Direction. Not getting any Doc for doing replication in Bi-direction( Two Way). If any one has done the same, then please share limitation of replication in Bi-direction through Golden Gate.

I am having difficulty in making the 32 bit Oracle client connection to an existing 64 bit DB. The 64 bit SQL*Plus will connect just fine, but when trying to configure the 32 bit client I can never get a successful TEST of the connection. It always returns "No TNS Listener". I have tried several things, but may be way off base. To name a couple ...
1) Stopped the 64 bit listener so my 32 bit listener can use Port 1521 ... no success
2) Tried naming the 32 bit listener to LISTENER32 to not conflict with the original LISTENER name ... no success
If there is a documented way to make this work, I would surely like to be pointed to the "how to" of this item. I need this as a commercial application I have that connects to the DB requires the 32 bit client.
I am having 11.2.0.1.0 database with windows2k3 OS. For ORA-609 error i have started server side tracing by adding TRACE_LEVEL_SERVER=16,TRACE_LEVEL_DIRECOTRY=D:TRACE,and DIAG_ADR_ENABLED=off in sqlnet.ora file and i reload the listener.
Now i want to stop tracing so i have tried TRACE_LEVEL_SERVER=off but it wouldnot work. After that i remove TRACE_LEVEL_SERVER=16,TRACE_LEVEL_DIRECOTRY=D:TRACE from sqlnet.ora file and reload the listener but trace file generation is going on D:TRACE. stop server side tracing.
When i connect from client to server the client looks up for the host address and port number in tnsnames.ora and connect to it via listener.ora in server.Where does pga and sga come into picture here?
